Dead Freight in Shipping: Meaning, Calculation, Charterparty Claims and Examples

What is Dead Freight?

Dead Freight is the compensation payable by a Voyage Charterer to a Shipowner when the Voyage Charterer has agreed to load a stated quantity of cargo but fails to supply the full contractual quantity for shipment. In practical chartering language, dead freight represents the freight that the Shipowner would have earned on the cargo space that was reserved under the Charter Party but left unused because the Voyage Charterer did not provide enough cargo.

Dead freight is most commonly encountered in Voyage Charterparties, especially in dry bulk, tanker, project cargo, and commodity trades where the freight is calculated by reference to the quantity of cargo loaded. If the Charter Party provides that the ship is to load a full cargo, a minimum quantity, or a quantity within an agreed tolerance, the Voyage Charterer must make cargo available within that contractual range. If the Voyage Charterer falls short, the Shipowner may claim dead freight for the missing quantity, provided that the Shipowner can show that the ship had the capacity and legal ability to load the cargo that was not supplied.

The commercial purpose of dead freight is simple: the Shipowner fixes the ship on the basis of expected freight earnings. If the Voyage Charterer reserves the ship but uses only part of the agreed cargo space, the Shipowner loses the opportunity to earn freight from that unused space. The dead freight claim is designed to place the Shipowner, so far as money can do so, in the position the Shipowner would have occupied if the agreed cargo quantity had been loaded.

Dead freight should not be understood as a random penalty. It is normally a contractual or damages-based claim arising from the Voyage Charterer’s failure to perform the cargo supply obligation. The claim may be straightforward when the Charter Party clearly states the cargo quantity and freight rate. However, dead freight can become more complicated where the cargo quantity is expressed with options such as MOLOO, MOLCO, MOLCHOP, “about,” “minimum/maximum,” “full and complete cargo,” or where draft restrictions, port limits, stowage factor, cubic capacity, load line restrictions, or safety considerations reduce the quantity that can actually be loaded.

Dead Freight Meaning in Ship Chartering

In ship chartering, the expression Dead Freight refers to freight that is commercially “lost” because the agreed cargo was not fully provided. The ship was made available, the cargo space existed, and the Shipowner expected to earn freight on the contractual quantity. However, part of that freight becomes “dead” because the corresponding cargo was never loaded.

The word “dead” does not mean that the ship has suffered physical damage or that the cargo is unusable. It means that the freight-earning opportunity attached to the unused carrying capacity has been lost. A dead freight claim therefore focuses on the difference between the cargo quantity contractually required and the cargo quantity actually shipped.

Dead freight usually arises when the Charter Party states a cargo quantity in one of the following ways:

Exact Quantity: The Voyage Charterer agrees to load a fixed quantity, such as 50,000 metric tons.
Minimum Quantity: The Voyage Charterer agrees to load not less than a stated quantity, such as minimum 45,000 metric tons.
Quantity Range: The Charter Party provides a range, such as 45,000/50,000 metric tons.
Full and Complete Cargo: The Voyage Charterer must load as much cargo as the ship can safely and lawfully carry for the voyage.
More or Less Option: The cargo quantity is subject to a tolerance option, such as 10% more or less in Owners’ option or Charterers’ option.

In each case, the first question is not simply how much cargo was missing. The first question is what quantity the Voyage Charterer was contractually required to provide. Once that contractual quantity is identified, the actual loaded quantity can be compared against it. The shortfall then becomes the starting point for a dead freight calculation.

Dead Freight in Voyage Charterparties

Dead freight belongs primarily to the world of Voyage Charterparties. Under a Voyage Charterparty, the Shipowner agrees to carry cargo from one place to another in exchange for freight. The freight may be calculated per metric ton, per long ton, per cubic meter, per unit, or sometimes on a lump sum basis. Where freight is calculated by the quantity loaded, the actual cargo quantity directly affects the Shipowner’s revenue.

If a Voyage Charterer fixes a ship for 60,000 metric tons of cargo but loads only 55,000 metric tons, the Shipowner may have lost freight on 5,000 metric tons. If the shortage is the Voyage Charterer’s contractual responsibility, the Shipowner may claim dead freight for that shortfall.

The dead freight concept is particularly important in bulk shipping because a bulk carrier’s commercial value depends heavily on cargo intake. A difference of a few thousand metric tons can represent a substantial freight loss, especially on long voyages or high freight-rate fixtures. In commodity trades, where margins may be tight and market timing is important, a disputed dead freight claim can become a serious financial issue.

Dead freight is less relevant where the freight is payable as a true lump sum regardless of how much cargo is loaded. If the Voyage Charterer pays a fixed lump sum for the voyage and is free to load more or less cargo within safety and contractual limits, the Shipowner may already receive the full agreed freight even if the cargo loaded is below the ship’s full capacity. In that situation, there may be no loss of freight to recover as dead freight unless the Charter Party contains a separate provision.

Dead Freight and Lump Sum Freight

A common way to avoid dead freight disputes is to agree freight on a lump sum basis. Lump sum freight means that the Voyage Charterer pays an agreed total amount for the voyage, regardless of the exact quantity loaded, subject to any express contractual restrictions. This can be attractive when the Voyage Charterer is uncertain about the final cargo quantity or when the parties prefer simplicity.

For example, if the freight is fixed at a lump sum of USD 900,000 for the voyage, the Shipowner receives USD 900,000 whether the Voyage Charterer loads 42,000 metric tons or 45,000 metric tons, unless the Charter Party states otherwise. Because the Shipowner’s freight is not reduced by the smaller cargo quantity, there may be no dead freight claim.

However, lump sum freight must be drafted carefully. If the Charter Party also contains a minimum cargo obligation, or if the lump sum is linked to a declared quantity, disputes may still arise. The parties should make clear whether the Voyage Charterer has complete freedom to load any quantity within the ship’s safe intake, or whether the Voyage Charterer must still provide a minimum cargo quantity.

Dead Freight, Freight, Demurrage and Detention

Dead freight should be distinguished from freight, demurrage, and damages for detention. These terms are related to the commercial earnings of the ship, but they serve different purposes.

Freight: Freight is the agreed remuneration payable to the Shipowner for carrying cargo from the loading port to the discharging port.
Dead Freight: Dead freight is compensation for cargo that should have been loaded but was not supplied by the Voyage Charterer.
Demurrage: Demurrage is agreed compensation payable when loading or discharging takes longer than the allowed laytime.
Damages for Detention: Damages for detention may arise where the ship is delayed beyond the contractual framework and demurrage does not fully cover the claim.

Although these claims are different, they often appear together in Charter Party clauses. A lien clause, for example, may state that the Shipowner has a lien on cargo for freight, dead freight, demurrage, and damages for detention. This is commercially important because if the Voyage Charterer fails to pay, the Shipowner may seek security against the cargo, provided that the lien is valid, incorporated, and enforceable in the relevant jurisdiction.

When Does Dead Freight Arise?

Dead freight normally arises when three conditions are present. First, the Charter Party must impose an obligation on the Voyage Charterer to load a certain cargo quantity. Second, the ship must be able and ready, within the contractual and legal limits, to load that quantity. Third, the Voyage Charterer must fail to provide the required cargo quantity.

The issue is not always whether the ship could theoretically carry more cargo. The ship’s actual loadable quantity may depend on a series of technical and commercial factors, including:

Summer, Winter, Tropical or Fresh Water Load Line: The relevant load line may restrict how deeply the ship can be loaded.
Draft Restrictions: Loading berth, sailing channel, river passage, canal transit, bunkering port, or discharging berth draft restrictions may reduce permissible intake.
Stowage Factor: A light cargo may fill the ship’s cubic capacity before the deadweight is fully used, while a heavy cargo may reach draft limits before the holds are full.
Bunkers and Constant Weights: Fuel, freshwater, stores, sludge, ballast, and constants affect the ship’s available deadweight for cargo.
Port and Berth Safety: A ship cannot be required to load beyond safe access, safe departure, or local port limits.
Cargo Characteristics: Moisture content, angle of repose, trimming requirements, hazardous properties, or segregation requirements may affect loadability.
Charter Party Options: MOLOO, MOLCO, MOLCHOP, “about,” and similar quantity terms affect the contractual quantity.

Because of these factors, a dead freight claim should be supported by proper calculations and documents. The Shipowner must be able to show that the ship could have loaded the additional cargo and that the shortage was not caused by the Shipowner’s own fault, the ship’s deficiency, or a legitimate safety restriction.

How Do You Calculate Dead Freight?

The basic dead freight formula is:

Dead Freight = Cargo Shortfall × Freight Rate

However, this simple formula must be applied carefully. The cargo shortfall should be measured against the contractual quantity, not merely against the ship’s maximum physical capacity. The freight rate should be the contractual rate applicable to the missing cargo. If the Charter Party provides a specific method for calculation, that contractual method should be followed.

A practical calculation normally follows these steps:

Identify the Contractual Cargo Quantity: Read the Charter Party quantity clause and determine whether the obligation is exact, minimum, maximum, full cargo, or subject to an option.
Identify Who Holds the Quantity Option: Determine whether the final quantity is in the Shipowner’s option, Voyage Charterer’s option, or cargo supplier’s option.
Check the Master’s Declaration: If the Master declares the loadable quantity, confirm that the declaration is based on proper draft, stability, stowage, cubic, bunker, and port restriction calculations.
Confirm the Actual Loaded Quantity: Use bills of lading, draft survey figures, shore scale figures, mate’s receipts, or other agreed documents.
Calculate the Shortfall: Subtract the actual loaded quantity from the contractual quantity that should have been loaded.
Apply the Freight Rate: Multiply the shortfall by the applicable freight rate.
Consider Contractual Adjustments: Apply any express deductions, savings, exceptions, commission, brokerage, or special provisions if the Charter Party requires them.
Issue a Dead Freight Statement: Prepare a written claim with supporting documents and send it in accordance with the Charter Party’s notice and payment provisions.

Dead Freight Calculation Example

Assume the Charter Party provides as follows:

Contractual cargo quantity: 55,000 metric tons
Actual cargo loaded: 51,800 metric tons
Freight rate: USD 24 per metric ton

The calculation would be:

55,000 metric tons – 51,800 metric tons = 3,200 metric tons shortfall

3,200 metric tons × USD 24 = USD 76,800 dead freight

In this example, the Voyage Charterer would owe USD 76,800 as dead freight, assuming that the Shipowner was entitled to receive cargo up to 55,000 metric tons and that the shortage was caused by the Voyage Charterer’s failure to supply cargo.

In practice, the parties may also argue about whether the freight rate should be adjusted for brokerage, address commission, loading costs, discharging costs, or savings. The answer depends on the Charter Party wording and the governing law. Therefore, the calculation should not be prepared mechanically; it should be tied to the exact contract.

Deadfreight Example with MOLOO

Consider a Charter Party stating:

60,000 metric tons, 10% MOLOO

MOLOO means More or Less in Owners’ Option. This gives the Shipowner, usually through the Master, the right to declare the final cargo quantity within the agreed tolerance. With 60,000 metric tons and 10% MOLOO, the Master may normally call for a quantity between 54,000 metric tons and 66,000 metric tons, subject to the ship’s safe and lawful loadable intake.

If the Master validly declares 64,000 metric tons and the Voyage Charterer supplies only 60,500 metric tons, the shortfall is 3,500 metric tons. If the freight rate is USD 28 per metric ton, the dead freight would be:

3,500 metric tons × USD 28 = USD 98,000

The Shipowner must still be able to justify the declaration. If the Master declares an excessive quantity that cannot be loaded because of draft limits, stability restrictions, stowage factor, port rules, or discharging berth restrictions, the dead freight claim may be reduced or rejected.

MOLOO, MOLCO and MOLCHOP in Dead Freight Claims

Cargo quantity options are central to many dead freight disputes. The same shortage can produce different results depending on who holds the option.

MOLOO: More or Less in Owners’ Option. The Shipowner may declare the final quantity within the agreed margin. If the Voyage Charterer fails to load the quantity validly declared by the Shipowner, dead freight may arise.
MOLCO: More or Less in Charterers’ Option. The Voyage Charterer may declare the final quantity within the agreed margin. Dead freight is usually measured against the minimum or the quantity selected by the Voyage Charterer, depending on the wording and timing of the declaration.
MOLCHOP: More or Less in Charterers’ Option. This is another expression often used to describe the Voyage Charterer’s quantity option.
About: The word “about” may allow a reasonable margin, but the margin is not always fixed unless the Charter Party states it clearly.
Minimum/Maximum: If the Charter Party says minimum 50,000 metric tons, the Voyage Charterer must normally provide at least that amount unless prevented by a contractual exception.

Where the Charter Party uses quantity options, timing matters. If a party must declare the final quantity before loading, that declaration should be made clearly and promptly. Ambiguity in the declaration can later create disputes about whether dead freight is payable and on what quantity.

Full and Complete Cargo

A Charter Party may state that the Voyage Charterer must load a Full and Complete Cargo. This expression generally requires the Voyage Charterer to provide enough cargo to fill the ship’s available carrying capacity, subject to the ship’s safe draft, cubic capacity, stability, port restrictions, cargo characteristics, and agreed contractual limits.

A full and complete cargo does not mean that the ship must be loaded recklessly or beyond safety limits. The ship must not be overloaded. It must also comply with load line rules, stability requirements, port limitations, and good seamanship. Therefore, when calculating dead freight under a full and complete cargo clause, the Shipowner must establish the ship’s true loadable quantity for the voyage.

For dry bulk cargoes, the ship’s intake can be affected by the cargo’s stowage factor. A dense cargo such as iron ore may bring the ship to its draft limit before all hold space is filled. A lighter cargo such as grain may fill the holds before the ship reaches maximum deadweight. In each case, the ship’s loadable cargo quantity must be assessed realistically.

Dead Freight and the Master’s Role

The Ship Master plays an important role in dead freight matters. The Master is often responsible for calculating or declaring the ship’s loadable cargo quantity, taking into account draft, trim, stability, bunkers, ballast, constants, load line zone, port restrictions, river limits, canal limits, and cargo stowage factor.

The Master should not declare a quantity casually. A careless or unsupported declaration may weaken the Shipowner’s dead freight claim. The Master’s declaration should be based on proper calculations and should be recorded in writing. If the Voyage Charterer fails to supply the declared quantity, the Master should issue an appropriate protest or letter recording the shortage.

Useful documents may include:

Loading plan and stowage plan
Draft survey reports
Bunker ROB figures
Ballast condition records
Loadable quantity calculations
Port draft restriction information
Weather, tide, and sailing condition records
Mate’s receipts
Bills of lading
Statement of facts
Notice of protest or letter of reservation

A well-documented claim is much stronger than a claim based only on a final invoice. Dead freight disputes are often decided by the quality of contemporaneous evidence.

Who Pays Dead Freight?

Dead freight is normally payable by the Voyage Charterer because the Voyage Charterer is the party that promised to provide cargo under the Charter Party. If the Voyage Charterer fails to provide the agreed cargo quantity, the Voyage Charterer may be liable to compensate the Shipowner.

However, commercial chains can complicate the matter. The Voyage Charterer may be a trader, cargo seller, cargo buyer, receiver, disponent shipowner, or intermediary. The physical cargo may be supplied by a shipper who is not the contractual Voyage Charterer. The Shipowner’s primary claim remains against the contractual counterparty, unless the Charter Party, bill of lading, guarantee, indemnity, or local law gives the Shipowner rights against another party.

Because of this, Shipowners should not assume that the physical shipper is liable for dead freight merely because the shipper failed to bring enough cargo to the berth. The contract must be checked carefully. Similarly, Voyage Charterers should ensure that their sale contract or supply contract protects them if the cargo supplier fails to provide the promised quantity.

Shipowners’ Right to Dead Freight

The Shipowner’s right to dead freight depends on the Charter Party and the circumstances of loading. The Shipowner must normally show that:

The Voyage Charterer had a contractual obligation to provide a specified cargo quantity or a full cargo.
The ship was ready and able to load the missing quantity.
The missing quantity was not loaded.
The shortage was caused by the Voyage Charterer’s failure or by a risk allocated to the Voyage Charterer.
The Shipowner suffered a freight loss or is otherwise entitled to the contractual dead freight amount.

The Shipowner should protect the claim during loading. If it becomes clear that the cargo supplied is insufficient, the Master or Shipowner’s agent should notify the Voyage Charterer and reserve the Shipowner’s rights. If the ship sails without protest and without proper documentation, the Shipowner may still have a claim, but proving it may become more difficult.

Dead Freight Charter Party Clauses

A well-drafted dead freight clause can prevent later uncertainty. A Charter Party clause dealing with dead freight should address the following issues:

Cargo Quantity: The clause should clearly state whether the cargo quantity is exact, minimum, maximum, about, range-based, or subject to a tolerance option.
Option Holder: The clause should identify whether the quantity option belongs to the Shipowner, Voyage Charterer, or another party.
Declaration Procedure: The clause should state when and how the final cargo quantity must be declared.
Calculation Method: The clause should specify how dead freight is calculated if the required cargo is not supplied.
Freight Rate: The clause should confirm whether the same freight rate applies to dead freight or whether a different rate is agreed.
Commissions and Deductions: The clause should state whether brokerage, address commission, taxes, loading expenses, or other deductions apply.
Evidence: The clause may identify the documents used to determine loaded quantity, such as bills of lading, draft survey, shore scales, or terminal figures.
Payment Time: The clause should say when dead freight becomes due and how it must be paid.
Lien Rights: The clause may connect dead freight to the Shipowner’s lien on cargo, freight, sub-freights, or other security.
Exceptions: The clause should state whether dead freight is excused by force majeure, port closure, strikes, export restrictions, safety restrictions, or other events.

Dead freight clauses should be written with precision because disputes often arise from small differences in wording. A vague cargo quantity clause can create a major claim if the freight market moves sharply or if the cargo supply fails at the loading port.

Dead Freight and Lien on Cargo

Many Voyage Charterparties give Shipowners a lien on cargo for freight, dead freight, demurrage, and damages for detention. A lien is a form of security. It may allow the Shipowner to retain possession of cargo until amounts due are paid, provided that the lien is contractually valid and enforceable under the relevant law and local practice.

A lien for dead freight can be commercially valuable because the Voyage Charterer may not pay immediately. However, exercising a lien is not always simple. The Shipowner must consider whether the lien is incorporated into the bill of lading, whether the cargo owner is bound by the relevant terms, whether the debt is already due, whether local law recognizes the lien, and whether retaining the cargo may expose the Shipowner to claims from cargo interests.

The practical enforcement of a lien may be difficult where the cargo has been sold to third parties, where local courts are hostile to lien enforcement, where the bill of lading does not properly incorporate the Charter Party clause, or where cargo interests obtain local court orders for release. Therefore, while a lien clause can strengthen the Shipowner’s position, it should not be treated as an automatic guarantee of payment.

Dead Freight and Cesser Clauses

A cesser clause may state that the Voyage Charterer’s liability ceases once the cargo is shipped, usually on the basis that the Shipowner has a lien on cargo for freight, dead freight, demurrage, or other charges. The relationship between cesser and lien wording can be very important in dead freight disputes.

If the Voyage Charterer argues that liability has ceased, the Shipowner may need to show that the lien was effective and available. If the lien cannot be enforced in practice, the Voyage Charterer may remain liable depending on the wording of the Charter Party and the governing law. The key commercial point is that a cesser clause should not be read in isolation. It must be considered together with the lien clause and the actual ability of the Shipowner to recover from the cargo.

Dead Freight in Bills of Lading

Dead freight may also become relevant in bill of lading disputes. A bill of lading may incorporate the Charter Party terms, including lien provisions for dead freight. However, incorporation must be effective. A cargo receiver or bill of lading holder may dispute liability if the relevant Charter Party clause is not clearly incorporated or if the claim is personal to the Voyage Charterer.

For this reason, Shipowners should ensure that the bill of lading wording is consistent with the Charter Party where a lien for dead freight is intended. Where the cargo is to be released without payment, the Shipowner should consider whether security is required before delivery.

Dead Freight and Cargo Shortage

Dead freight should not be confused with an outturn shortage at the discharging port. Dead freight concerns cargo that was not loaded at the loading port. An outturn shortage concerns cargo that was loaded but not delivered in full, or was allegedly lost, damaged, spilled, stolen, or mismeasured during the voyage or discharge.

The difference is important. Dead freight is a claim by the Shipowner for unused cargo capacity. Cargo shortage is usually a claim by cargo interests against the carrier or by receivers against sellers. The evidence is also different. Dead freight depends heavily on loading documents and contractual quantity obligations. Outturn shortage depends on loading and discharging figures, bills of lading, draft surveys, shore scale records, and cargo condition evidence.

Dead Freight and Draft Survey Evidence

Draft surveys are often central in dry bulk dead freight claims. A draft survey estimates the weight of cargo loaded by measuring the ship’s draft before and after loading and adjusting for water density, ballast, bunkers, freshwater, stores, and constants. Because draft survey results can affect substantial sums, both parties should pay close attention to the survey method.

Disputes may arise where shore scale figures differ from draft survey figures. The Charter Party should ideally identify which figure governs for freight and dead freight purposes. If the Charter Party is silent, the parties may need to rely on evidence of custom, the bill of lading quantity, the mate’s receipt, independent survey reports, and the reliability of the measuring method used at the loading port.

Dead Freight and Cargo Stowage Factor

The cargo’s stowage factor can determine whether the ship can load the agreed quantity. Stowage factor measures the volume occupied by a unit weight of cargo. A cargo with a high stowage factor takes more space per metric ton; a cargo with a low stowage factor is denser and heavier.

If the Voyage Charterer declares a stowage factor that proves inaccurate, the ship may be unable to load the expected quantity. For example, a cargo described as having a stowage factor of 45 cubic feet per metric ton may actually stow at 52 cubic feet per metric ton. The ship may then cube out before reaching the expected weight. Whether dead freight is payable depends on the Charter Party wording, the accuracy of the cargo description, who gave the stowage factor, and whether the Shipowner relied on it when fixing the ship.

To avoid disputes, cargo descriptions should state the expected stowage factor, moisture condition, trimming requirements, and any known factors affecting loadability. The Shipowner should also check whether the ship’s cubic capacity is adequate for the cargo quantity proposed.

Dead Freight and Safe Loading Limits

A Voyage Charterer cannot normally be required to load cargo beyond safe or lawful limits. If the ship cannot load the agreed quantity because of a genuine draft restriction, load line restriction, port authority order, safety concern, cargo hazard, or stability limitation, the dead freight claim may fail or be reduced unless the Charter Party allocates that risk to the Voyage Charterer.

However, if the shortage results from the Voyage Charterer’s failure to provide cargo, late delivery of cargo to the terminal, export permit problems, cargo supplier default, shortage at the mine, warehouse disruption, or commercial inability to source cargo, the Voyage Charterer may remain liable for dead freight.

Dead Freight and Readiness to Load

The Shipowner should be able to show that the ship was ready to load the missing cargo. If the ship’s holds were unclean, the ship was not at the agreed berth, the ship was not ready in all material respects, or the ship could not legally load the cargo, the Voyage Charterer may argue that no dead freight is payable because the Shipowner was not in a position to carry the cargo.

Readiness to load includes practical and legal readiness. The ship should be physically ready, properly documented, within the agreed loading place, and capable of loading the cargo safely. The Shipowner’s dead freight claim becomes stronger when the Notice of Readiness, statement of facts, inspection records, hold cleanliness certificates, and loading documents all show that the ship was ready and able to load the agreed quantity.

Dead Freight and Deadweight Capacity

Dead freight is not the same as deadweight. Deadweight is the ship’s carrying capacity measured by weight, including cargo, bunkers, freshwater, stores, crew effects, ballast, and other weights. Dead freight is a monetary claim for cargo not loaded. The similarity in wording sometimes causes confusion, but the two concepts are different.

A ship may have enough deadweight capacity but not enough cubic capacity. A ship may have cubic space but not enough draft. A ship may have technical capacity but face a port restriction. For dead freight purposes, the relevant question is the contractual and practical cargo quantity the ship could and should have loaded for that voyage.

Dead Freight and Deadweight Cargo

The expression deadweight cargo refers to heavy cargo that uses the ship’s weight capacity more than its cubic capacity. Iron ore, steel products, minerals, and some concentrates may be deadweight cargoes. This is different from dead freight. Deadweight cargo describes the physical character of cargo; dead freight describes compensation for cargo not supplied.

Confusing these terms can lead to mistakes in chartering communications. Shipbrokers, operators, and chartering managers should distinguish clearly between cargo that is heavy by nature and freight that is claimed because cargo was not loaded.

Can a Shipowner Always Claim Dead Freight?

A Shipowner cannot automatically claim dead freight merely because the ship sailed with empty space. The claim depends on the Charter Party and evidence. The Shipowner may face difficulty if:

The Charter Party does not impose a minimum cargo obligation.
The freight is a true lump sum and no separate dead freight clause applies.
The Shipowner failed to declare the quantity properly under MOLOO.
The ship could not safely or lawfully load the additional cargo.
The shortage was caused by the Shipowner’s fault or the ship’s deficiency.
The Voyage Charterer was entitled to load a lower quantity under MOLCO or similar wording.
The Shipowner failed to mitigate the loss where mitigation was reasonably possible.
The evidence of actual loaded quantity or available space is unreliable.

For this reason, dead freight should be treated as a serious contractual claim requiring careful analysis, not as an automatic invoice.

Can the Voyage Charterer Defend a Dead Freight Claim?

A Voyage Charterer may defend a dead freight claim by arguing that the alleged shortfall was not contractually due, that the ship could not load the quantity claimed, that the Master’s declaration was invalid, that the cargo shortage was excused by the Charter Party, or that the Shipowner suffered no recoverable loss.

Common Voyage Charterer arguments include:

No Minimum Quantity: The Charter Party allowed the Voyage Charterer to load the actual quantity shipped.
Charterers’ Option: The quantity was in the Voyage Charterer’s option, and the Voyage Charterer selected a lawful lower quantity.
Invalid Declaration: The Shipowner’s declared quantity exceeded the ship’s safe or contractual loadable intake.
Ship Not Ready: The ship was not physically or legally ready to load the missing cargo.
Port Restriction: A draft, berth, river, canal, or authority restriction prevented the higher quantity.
Cargo Exception: A force majeure, strike, export ban, mine stoppage, or other contractual exception applied.
Measurement Dispute: The alleged shortfall is based on inaccurate figures.
Failure to Mitigate: The Shipowner could reasonably have reduced the loss but failed to do so.

These defenses are fact-sensitive. The outcome usually turns on the Charter Party wording, loading documents, operational evidence, and the law governing the contract.

Dead Freight and Mitigation

Where dead freight is treated as damages, mitigation may become relevant. The Shipowner may be expected to take reasonable steps to reduce the loss where practical. For example, if substitute cargo is available at the loading port and can be loaded without unreasonable delay, expense, or contractual complication, the Shipowner may need to consider whether accepting it would reduce the claim.

However, mitigation does not require the Shipowner to act against the Charter Party, expose the ship to unsafe operations, accept unsuitable cargo, delay the voyage unreasonably, or enter into commercially unrealistic arrangements. The duty is one of reasonableness, not perfection.

Dead Freight and Partial Cargo

A partial cargo does not automatically create dead freight. The Charter Party may have been fixed for part cargo only. In some trades, the ship carries several parcels for different charterers. If one parcel is smaller than expected, dead freight depends on whether the relevant Voyage Charterer promised a specific minimum quantity and whether the Shipowner could have used the unused space for another cargo.

Where the ship is fixed for part cargo, the wording should specify whether the Voyage Charterer is liable for unused space, whether the Shipowner may load additional cargo, and whether dead freight applies if the declared quantity is not supplied.

Dead Freight in Dry Bulk Shipping

Dead freight is common in dry bulk shipping because cargo quantities are often linked to mining output, stockpile availability, terminal performance, cargo moisture, draft restrictions, and fluctuating commodity trades. Cargoes such as coal, grain, iron ore, bauxite, fertilizers, cement, sugar, salt, petcoke, concentrates, and aggregates may all give rise to dead freight disputes if the declared or agreed quantity is not loaded.

Dry bulk dead freight disputes often involve:

MOLOO or MOLCO cargo quantity declarations
Draft survey differences
Cargo stowage factor errors
Port draft restrictions
Terminal stockpile shortages
Moisture content and weight variations
Load line zone changes
Incorrect cargo nomination
Berth or channel depth limits
Short loading caused by shipper or supplier default

Because dry bulk cargo quantities can be affected by both ship and shore factors, the parties should exchange technical information early and document the basis of any loadable quantity declaration.

Dead Freight in Tanker Chartering

Dead freight may also arise in tanker trades where the Voyage Charterer fails to provide the agreed cargo quantity. Tanker calculations may involve cubic capacity, cargo density, temperature, load line restrictions, port draft, segregation requirements, slop capacity, vapor pressure restrictions, and safety margins.

Tanker dead freight disputes may also involve whether the ship’s tanks were suitable, clean, inerted, certified, and ready for the nominated cargo. If the ship could not load the missing cargo because of tank condition, temperature restrictions, previous cargo residues, or operational deficiencies, the Voyage Charterer may resist the dead freight claim.

Dead Freight and Cargo Nomination

The Voyage Charterer’s cargo nomination can affect dead freight. If the Charter Party allows a range of cargoes, the nominated cargo must be compatible with the ship and the agreed voyage. If the Voyage Charterer nominates cargo with an inaccurate stowage factor, unsuitable characteristics, or a quantity that cannot be supplied, a dead freight claim may follow.

The Shipowner should check the cargo nomination against the ship’s hold capacity, tank capacity, cargo gear, load line, draft restrictions, stability limits, and any cargo-specific safety rules. If there is a problem, the Shipowner should raise it promptly rather than waiting until the end of loading.

Dead Freight and Laytime

Dead freight and laytime may interact but they are different claims. Laytime concerns the time allowed for loading or discharging. Dead freight concerns cargo quantity not supplied. A Voyage Charterer may be liable for demurrage because loading took too long and also liable for dead freight because the full cargo was not loaded. Conversely, a ship may complete loading quickly but still sail short of cargo, giving rise to dead freight without demurrage.

The statement of facts should record both time and quantity issues accurately. If loading stops because no more cargo is available, the record should identify the time when cargo supply ended, any protests made, and whether the Master requested additional cargo.

Dead Freight and Freight Payment

The time when dead freight becomes payable depends on the Charter Party. It may be payable together with freight, on signing or releasing bills of lading, before sailing, after completion of loading, upon invoice, or at another agreed time. If the Charter Party is silent, the parties may need to consider the general law of damages and the freight payment terms.

Shipowners should avoid uncertainty by including clear wording. Voyage Charterers should also check whether dead freight is payable before bills of lading are released, because this may affect documentary sale arrangements and letters of credit.

Dead Freight Statement

A dead freight statement is a practical document showing the basis of the claim. A proper dead freight statement should include:

Charter Party date and parties
Ship name
Voyage details
Contractual cargo quantity
Option wording, if any
Declared loadable quantity
Actual loaded quantity
Shortfall quantity
Freight rate
Total dead freight amount
Supporting documents
Payment instructions
Reservation of rights

The statement should be consistent with the bills of lading, mate’s receipts, draft survey reports, loading documents, and any notices or protests issued during loading.

How to Avoid Dead Freight Disputes

Dead freight disputes can often be avoided by clear drafting and disciplined operations. The parties should address the issue before the ship arrives, not after the cargo shortage has already occurred.

Draft the Quantity Clause Clearly: Avoid vague wording where the commercial intention is a firm cargo commitment.
State the Option Holder: Make clear whether the option belongs to Shipowners, Voyage Charterers, or another party.
Agree the Calculation Method: State exactly how dead freight will be calculated.
Define the Governing Quantity Evidence: Specify whether draft survey, shore scale, bill of lading, or another figure controls.
Check Port Restrictions Early: Confirm draft, berth, channel, tide, air draft, and discharging port restrictions before declaring quantity.
Verify Cargo Availability: Voyage Charterers should confirm that the cargo is physically available and export-ready.
Exchange Stowage Factor Information: Incorrect stowage factor is a common cause of disputes.
Issue Clear Notices: Shipowners should reserve rights promptly if the cargo supply is insufficient.
Record Events Accurately: The statement of facts should identify cargo stoppages, shortage, and any protest.
Use Consistent Documents: Avoid contradictions between Charter Party, bills of lading, mate’s receipts, and invoices.

Practical Checklist for Shipowners

Before claiming dead freight, Shipowners should ask:

What exact cargo quantity did the Voyage Charterer promise to load?
Was the cargo quantity subject to MOLOO, MOLCO, MOLCHOP, or another option?
Was the final quantity declared validly and on time?
Could the ship safely and lawfully load the missing quantity?
Did any port, berth, draft, river, canal, or load line restriction apply?
Was the ship ready to load in all material respects?
What quantity was actually loaded?
Which document proves the loaded quantity?
Was a protest or reservation issued?
Does the Charter Party provide a lien for dead freight?
When is dead freight payable?
Are there any defenses, exceptions, or mitigation issues?

Practical Checklist for Voyage Charterers

Before resisting or negotiating a dead freight claim, Voyage Charterers should ask:

Did the Charter Party truly require the higher quantity claimed by the Shipowner?
Was the quantity in Charterers’ option?
Was the Shipowner’s declaration within the agreed range?
Was the declaration commercially and technically justified?
Could the ship load the alleged missing cargo safely?
Was the cargo shortage caused by an excepted event?
Did the Shipowner protest during loading?
Are the draft survey and bill of lading figures reliable?
Did the Shipowner suffer a recoverable loss?
Can the claim be reduced by contractual deductions or savings?
Is there exposure under a sale contract, supply contract, or guarantee?

Dead Freight in Chartering Negotiations

Dead freight should be considered during fixture negotiations, not only when a dispute appears. Shipowners want protection against underloading. Voyage Charterers want flexibility where cargo availability is uncertain. The balance is usually achieved through clear quantity tolerances, careful option wording, and realistic assessment of the ship’s loadable intake.

Shipbrokers should be precise when recording fixture recap terms. A small difference between “60,000 metric tons 10% MOLOO” and “60,000 metric tons 10% MOLCO” can change the commercial result completely. Similarly, “full cargo” and “about full cargo” may not produce the same outcome. Accurate recap wording can prevent later arbitration or litigation.

Dead Freight and Commercial Risk

For Shipowners, the dead freight risk is loss of earnings from underutilized cargo space. For Voyage Charterers, the risk is paying for cargo space they could not fill. For traders, the risk may come from a mismatch between the sale contract and the Charter Party. A trader may buy or sell cargo on one quantity basis but fix the ship on another. If the cargo supplier defaults, the trader may still owe dead freight to the Shipowner.

Good chartering practice requires aligning the sale contract, cargo supply contract, terminal arrangements, financing documents, and Charter Party. If the Voyage Charterer has promised a minimum quantity to the Shipowner, the Voyage Charterer should ensure that the cargo supplier is equally committed to providing that quantity.

Dead Freight and Common Drafting Mistakes

Common drafting mistakes include:

Using “about” without defining the tolerance.
Failing to state who holds the quantity option.
Failing to state when the final quantity must be declared.
Using inconsistent cargo quantities in the recap and Charter Party.
Failing to address draft restrictions at both loading and discharging ports.
Failing to state whether dead freight is subject to commission.
Failing to provide a clear payment date for dead freight.
Failing to preserve lien rights for dead freight.
Failing to identify the controlling weight certificate or survey.
Assuming lump sum freight automatically removes every cargo quantity dispute.

Dead Freight and Evidence Preservation

Dead freight claims are evidence-driven. The Shipowner should preserve all operational records showing the ship’s ability to load the missing cargo and the Voyage Charterer’s failure to provide it. Voyage Charterers should preserve all records showing cargo availability, port restrictions, ship limitations, and any contractual excuse.

Important evidence may include:

Fixture recap and Charter Party
Loadable quantity declaration
Loading plan
Stability calculations
Draft restrictions and port information
Draft survey reports
Bunker and ballast records
Hold capacity or tank capacity plans
Cargo stowage factor data
Terminal loading records
Emails and notices
Statement of facts
Letters of protest
Mate’s receipts and bills of lading

Dead Freight Summary

Dead Freight is the compensation due to the Shipowner when the Voyage Charterer fails to load the cargo quantity required under the Voyage Charterparty. It is closely connected with cargo quantity clauses, freight rate wording, loadable quantity declarations, MOLOO and MOLCO options, draft restrictions, stowage factor, bills of lading, and evidence from the loading port.

The basic calculation may look simple, but the legal and commercial analysis can be detailed. The parties must identify the contractual quantity, confirm the ship’s actual safe loadable intake, measure the loaded quantity accurately, and apply the agreed freight rate and contract terms. A successful dead freight claim depends not only on the existence of unused space but on the Voyage Charterer’s contractual obligation to provide cargo and the Shipowner’s ability to prove the resulting loss.

For Shipowners, dead freight protects expected voyage earnings. For Voyage Charterers, careful quantity wording protects against paying for cargo space that was never firmly promised or could not safely be used. For both sides, the safest approach is clear drafting, realistic cargo planning, accurate loadable quantity calculations, prompt notices, and complete documentary evidence.
