Freight in Shipping: Voyage Charter Freight, Deadfreight, Prepaid Freight, and Freight Payment Explained

 

Freight

Freight is the payment earned by a Shipowner for the carriage of cargo by sea under a voyage charter. It is the commercial price of maritime transportation and represents the financial reward for placing the ship at the service of the Charterer for a particular voyage. In ordinary dry cargo chartering, freight is often expressed as United States dollars per metric ton of cargo, although the parties may also agree lump sum freight, minimum freight, freight on a measurement basis, freight on intake quantity, freight on delivered quantity, or another formula suitable for the trade.

The word Freight must be kept separate from hire. Freight belongs to voyage chartering. Hire belongs to time chartering. Under a voyage charter, the Shipowner undertakes a defined carrying service: the ship loads the agreed cargo at the loading port and carries it to the agreed discharging port or range. Under a time charter, the Shipowner provides the commercial use of the ship and crew for a period of time, and the Charterer pays daily hire while the ship remains on hire. The two payments are connected with different commercial structures and different legal consequences.

Freight is not merely a number inserted into a charter party. It is the economic center of the voyage. The freight level must compensate the Shipowner for the cost and risk of performing the voyage and must also produce a return on the ship’s employment. A voyage may look attractive at first sight, but if the freight does not properly cover bunkers, port charges, canal dues, cargo expenses, commissions, time exposure, insurance premiums, and likely delay, the voyage may become unprofitable.

In voyage chartering, the Shipowner normally keeps control of the ship’s navigation, crewing, technical operation, insurance, and day-to-day management. The Charterer normally provides the cargo, nominates ports within the agreed limits, and pays freight when the contract requires payment. The freight bargain therefore allocates commercial risk between the parties. The Shipowner accepts the obligation to carry, and the Charterer accepts the obligation to pay for that carriage.

What is Freight?

Freight is the consideration payable for carrying cargo from one place to another by ship. It is the price paid for the sea carriage service. In legal terms, freight is earned when the Shipowner has performed the agreed transportation service sufficiently to satisfy the charter party and the applicable law. In commercial terms, freight is the revenue generated by the voyage.

A freight rate is shaped by market forces and voyage economics. The rate may rise when cargo demand is strong, ships are scarce, port congestion is high, or bunker prices increase. The rate may fall when ships are plentiful, cargo volumes decline, or Charterers have greater bargaining power. Freight markets are therefore cyclical, volatile, and sensitive to world trade, commodity demand, fleet supply, weather, geopolitics, port congestion, energy prices, and financial conditions.

Freight may be agreed on different bases. The most familiar method is a rate per metric ton of cargo. In some trades, freight is paid per long ton, short ton, cubic meter, revenue ton, freight ton, unit, piece, container, vehicle, or package. In project cargo and heavy-lift work, a lump sum figure may be more practical because the cargo cannot be measured easily by ordinary bulk cargo standards. In tanker trades, freight may be expressed through market scales, percentage rates, or other specialized formulas.

The freight clause should make the payment basis unmistakable. It should state whether freight is calculated on the quantity loaded, the quantity delivered, the bill of lading quantity, shore scale weight, draft survey weight, or another agreed measurement. A small difference in wording can create a significant financial difference, particularly in cargoes where moisture loss, handling loss, natural wastage, or measurement discrepancy is common.

Freight in Voyage Chartering

The voyage charter is the classic commercial framework for freight. The Shipowner agrees to carry the cargo on a particular voyage, and the Charterer agrees to pay freight for that service. The voyage may be simple, involving one loading port and one discharging port, or it may be complex, involving several loading ports, several discharging ports, optional ranges, part cargoes, cargo substitutions, draft restrictions, river passages, canals, ice areas, or politically sensitive destinations.

The freight clause in a voyage charter party should normally address the following matters:

• freight rate or lump sum amount;
• currency of payment;
• cargo quantity basis;
• whether freight is payable on loaded quantity or delivered quantity;
• time of payment;
• banking details and bank charges;
• whether payment is made before or after bills of lading are released;
• whether freight is prepaid, payable on shipment, payable after loading, payable on arrival, or payable on delivery;
• whether freight is returnable or non-returnable;
• whether deductions or set-off are allowed;
• whether freight tax is for Shipowner’s or Charterer’s account;
• whether commission and address commission are deducted from freight;
• whether deadfreight is payable if the Charterer fails to supply the agreed cargo quantity.

In practice, freight wording is often negotiated quickly, but it should never be treated as routine. Freight is usually the largest payment in a voyage charter. Disputes about freight can affect cargo release, bills of lading, letters of credit, liens, demurrage, commission, and cash flow. For this reason, the freight clause should be drafted with the same care as the laytime, demurrage, cargo, and port clauses.

Freight and Hire Compared

Freight and hire are both payments made for the commercial use of a ship, but they arise under different chartering structures. Freight is voyage-based. Hire is time-based. Freight is normally earned by carrying cargo to the destination. Hire is normally earned by making the ship available for the Charterer’s service during the charter period.

In a voyage charter, the Shipowner usually bears the risk of voyage duration, subject to laytime and demurrage provisions. If the voyage takes longer because of weather, currents, distance, routing, or ordinary sea conditions, the Shipowner may absorb that time unless the contract gives additional compensation. In a time charter, the Charterer usually bears the commercial risk of time because hire continues to run while the ship is on hire, unless an off-hire event occurs.

The distinction also affects bunkers. In a voyage charter, the Shipowner normally pays for bunkers and includes expected bunker cost in the freight rate. In a time charter, the Charterer normally pays for bunkers consumed during the charter period. Therefore, a voyage freight calculation must include expected fuel consumption at sea and in port, whereas a time charter hire calculation is usually separate from bunker cost.

Freight also differs from hire in its relationship with cargo delivery. The right to freight has traditionally been connected with the carriage and arrival of goods. Hire, by contrast, does not depend on the arrival of a particular cargo at a destination. A time Charterer may employ the ship in several voyages during the charter period, and hire is payable because the ship is commercially available for service.

How Freight is Calculated

Freight calculation depends entirely on the contract. The same cargo, carried on the same ship, may produce a different freight amount depending on whether the parties agree freight on loaded quantity, delivered quantity, lump sum basis, minimum quantity basis, or measurement basis.

Freight per ton loaded is common in bulk trades. The quantity may be established by draft survey, shore scale, bill of lading figure, terminal measurement, or other agreed evidence. If freight is payable on bill of lading quantity, the Shipowner is normally paid by reference to the figure stated in the bill of lading, even if later outturn figures differ, subject to any contrary wording.

Freight per ton delivered shifts more quantity risk onto the Shipowner because the amount payable depends on the cargo actually delivered. This may be relevant where natural loss, leakage, evaporation, handling shortage, moisture change, or measurement difference is expected. The parties should state clearly whether shortage claims are separate from freight calculation or whether freight is automatically reduced by outturn shortage.

Lump sum freight fixes the freight amount for the voyage. It may be attractive where the cargo quantity is uncertain, where the cargo is unusual, or where the parties want simplicity. Lump sum freight reduces the need to calculate freight by exact tonnage, but it may create disputes if the cargo quantity is materially different from what the parties expected. A clear clause should state whether the lump sum is payable regardless of quantity and whether deadfreight may still be claimed.

Minimum freight protects the Shipowner against underloading. If the Charterer agrees to pay freight on a minimum quantity, the Shipowner receives freight on that minimum even if less cargo is loaded. This is commercially similar to deadfreight, but it is usually built into the freight clause itself.

Freight ton calculations are common in liner, breakbulk, and general cargo trades. Freight may be charged by weight or measurement, whichever produces the greater amount. This reflects the fact that some cargoes are heavy and compact, while others are light but occupy significant space. A ship’s earning capacity depends on both weight capacity and cubic capacity.

Freight and Voyage Estimation

Before accepting a voyage charter, a Shipowner or Ship Operator should prepare a voyage estimate. The purpose is to calculate whether the proposed freight will produce a satisfactory return. A voyage estimate compares expected revenue against expected cost and time exposure.

A professional voyage estimate normally includes:

• cargo quantity and freight rate;
• total freight revenue;
• brokerage and commission;
• address commission, if applicable;
• loading port expenses;
• discharging port expenses;
• canal dues and transit costs;
• pilotage, towage, agency, and port dues;
• bunker consumption at sea;
• bunker consumption in port;
• bunker price and grade requirements;
• ballast voyage duration;
• laden voyage duration;
• expected waiting time and congestion;
• weather, ice, river, canal, or tidal delays;
• war risk, piracy, or special insurance premiums;
• daily operating cost of the ship;
• expected demurrage or despatch exposure;
• net result and daily equivalent earnings.

The final freight decision is not only mathematical. A Shipowner may accept a lower freight if the voyage positions the ship well for a stronger market afterward. A Shipowner may reject a high freight if the port is risky, the Charterer is unreliable, the cargo is dangerous, the trade is sanctioned, or the voyage would trap the ship in a weak area. Freight must therefore be evaluated commercially, operationally, and legally.

What Costs Must Freight Cover?

Freight must cover both visible and hidden costs. Visible costs include bunkers, port charges, canal dues, agency fees, and commissions. Hidden costs include time risk, operational uncertainty, ship depreciation, finance cost, maintenance exposure, insurance, opportunity cost, and market risk. A freight rate that covers only the obvious expenses may still be inadequate.

Bunker cost is often one of the largest voyage expenses. The freight rate must reflect the expected fuel consumption of the ship at the agreed or assumed speed, plus fuel used in port and during waiting periods. If the ship must trade inside an emission control area or use more expensive low-sulphur fuel, that cost must be considered. If the voyage involves slow steaming, the freight calculation must reflect the longer time needed to complete the voyage.

Port costs can vary dramatically between ports. Some ports are efficient and inexpensive, while others involve high dues, compulsory services, expensive agency charges, long waiting time, or difficult local practices. Canal dues can also be significant. A voyage through a major canal may save time and fuel, but the toll may be substantial. The freight must reflect the chosen route.

Commissions reduce the net freight received. Brokerage is payable to Shipbrokers involved in the fixture, and address commission may be payable to the Charterer or deducted for the Charterer’s benefit. If a Shipowner forgets to include commission in the voyage estimate, the net result may be overstated.

Freight should also account for risk. A voyage to an ice area, war risk area, piracy area, congested port, shallow draft port, politically sensitive country, or difficult river port may require a higher freight rate. The additional freight compensates not only for cost but also for uncertainty and exposure.

When is Freight Earned?

The right to receive freight is traditionally conditional on performance of the transportation service. Under the ordinary rule, freight is earned when the goods have been carried to the agreed destination and are ready for delivery to the person entitled to receive them. If the voyage never begins, or if the Shipowner does not carry the cargo to the destination, no freight is payable unless the charter party clearly changes that result.

This traditional rule reflects the commercial purpose of the bargain. The Charterer pays for carriage, not merely for the ship’s attempt to carry. If the carrying service is not provided, the freight is not earned. However, commercial parties are free to modify this position by contract. Many charter parties provide for freight to be paid earlier, such as on shipment, on completion of loading, on signing bills of lading, or within a fixed number of banking days after loading.

Where freight is payable in advance, the key question becomes whether the freight is returnable if the voyage is not completed. If the contract clearly provides that freight is prepaid and non-returnable, the Shipowner may be able to retain freight even if the cargo is later lost or the voyage is not completed, depending on the governing law and exact wording. If the clause is unclear, the parties may dispute whether the payment was truly earned freight, advance payment, or money paid subject to later performance.

Freight and Delivery of Cargo

Delivery is central to freight. The Shipowner normally earns freight by carrying the cargo to the destination and placing it in a condition where it can be delivered. The cargo does not always need to arrive undamaged for freight to be earned. A Shipowner may earn freight even where the cargo arrives damaged, provided the transportation service has been substantially performed. The cargo interest may still claim damages for the cargo damage, but that claim does not automatically eliminate the freight obligation.

For example, if a cargo of bulk grain arrives at the discharge port with part of the cargo damaged by moisture, the Shipowner may still be entitled to freight if the cargo has been carried and delivered, subject to any cargo claim. The receiver’s remedy may be a claim for damage, not refusal to pay all freight. Conversely, if the ship fails to reach the destination and the cargo is never delivered, the Shipowner may not earn freight under the traditional rule.

The distinction between freight and cargo damage claims is important. Freight is the price of carriage. Cargo damage is a separate claim arising from loss, damage, or breach of duty. Whether the Charterer or cargo interest can deduct a cargo claim from freight depends on the contract and applicable law. Some charter parties require freight to be paid in full without deduction, leaving claims to be pursued separately. Others allow certain deductions or set-offs.

Substantial Performance and Freight

The principle of substantial performance is essential in freight disputes. The question is whether the Shipowner has performed the service for which freight was agreed. If the essential service has been performed, freight may be payable even if performance was imperfect. If the essential service has not been performed, freight may not be earned.

Substantial performance depends on facts and contract wording. A small shortage, minor cargo damage, or ordinary handling loss may not defeat freight. A total failure to carry the cargo to the destination normally will. A serious failure that changes the commercial identity of the performance may create a difficult dispute. The court or tribunal must examine the charter party, cargo condition, quantity delivered, cause of loss, and commercial purpose of the contract.

Where only part of the cargo is carried, freight is generally payable for the part carried unless the charter party makes full carriage a condition precedent to any freight. Such a clause should be clear because freight is usually treated as earned in respect of cargo actually carried and delivered. The parties should therefore state expressly if freight on part cargo is not to be payable unless the whole cargo is delivered.

Part Cargo, Short Delivery, and Damaged Cargo

Freight disputes often arise where cargo is short-delivered or damaged. Short delivery may result from theft, spillage, natural loss, evaporation, measurement error, incorrect draft survey, leakage, handling loss, or cargo remaining in holds. Damaged cargo may result from water ingress, heating, contamination, rough handling, inherent vice, poor stowage, bad ventilation, cargo incompatibility, or perils of the sea.

The first question is whether freight is calculated on loaded quantity or delivered quantity. If freight is payable on loaded quantity, shortage at destination may not automatically reduce freight, although a cargo claim may exist. If freight is payable on delivered quantity, shortage directly affects the amount payable. If the charter party is silent or unclear, disputes may arise.

The second question is whether the cargo was substantially carried to the destination. If damaged goods arrive and remain deliverable as the contracted cargo, freight may still be earned. If the cargo is so damaged that it no longer has the identity or commercial character of the goods shipped, the analysis may become more complex. This is a factual question and may depend on expert evidence, cargo documents, survey reports, and sale contract requirements.

The third question is whether any deduction or set-off is permitted. A Charterer may want to deduct alleged cargo damage from freight. A Shipowner may insist that freight must be paid without deduction and that cargo claims must be resolved separately. Clear charter party drafting can prevent uncertainty.

Advance Freight and Prepaid Freight

Advance freight and prepaid freight are important because they alter the ordinary timing of freight payment. Instead of waiting until cargo delivery, the Charterer or shipper pays freight earlier. The payment may be due on shipment, on signing bills of lading, after completion of loading, or within a fixed number of banking days.

Prepaid freight is common in documentary sales. A bill of lading marked “freight prepaid” may be required under a letter of credit or sale contract. The buyer may want evidence that freight has already been paid, so that no freight demand will be made at destination. The statement on the bill of lading can therefore have commercial consequences beyond the charter party.

If a bill of lading states “freight prepaid” when freight has not actually been paid, serious disputes may arise. The Carrier may have difficulty demanding freight from the consignee because the document represents that freight has been prepaid. The Shipowner may then need to recover from the Charterer or shipper. This is why Ship Masters and agents should be cautious when bills of lading are presented for signature with freight statements that do not reflect the true payment position.

The charter party should state whether prepaid freight is returnable or non-returnable. If the parties intend the Shipowner to keep advance freight even if the cargo is lost later, the wording should be clear. If the parties intend freight to be returned if carriage is not completed, that should also be expressed. Ambiguity in prepaid freight clauses can lead to expensive disputes.

Lump Sum Freight

Lump sum freight is a fixed freight amount agreed for the voyage. It is often used when the parties want certainty or when cargo quantity cannot be conveniently calculated by tonnage. It may also be used for full cargoes where the Shipowner wants a guaranteed return regardless of small cargo variation.

Lump sum freight can be commercially useful, but it should be drafted carefully. The charter party should state whether the lump sum is payable even if the Charterer loads less cargo than expected. It should also state whether additional freight is payable if extra cargo is loaded and whether deadfreight can be claimed if the Charterer fails to supply the agreed cargo.

For example, if a ship is fixed for lump sum freight on a full cargo basis but the Charterer loads substantially less than expected, the Shipowner may argue that the lump sum remains payable. The Charterer may argue that the lump sum was based on a particular cargo quantity or cargo commitment. The result depends on the wording. A clear clause can avoid the dispute.

Deadfreight (DF)

Deadfreight is compensation payable when the Charterer fails to load the agreed cargo quantity and the Shipowner loses freight on the unused carrying capacity. It is not freight on cargo carried. It is damages for cargo that should have been loaded but was not supplied.

The right to deadfreight usually arises when the Charterer has promised to load a full and complete cargo or a stated quantity, and the Shipowner has provided the ship ready and able to load that cargo. If the Charterer supplies less cargo without contractual excuse, the Shipowner may claim the freight that would have been earned on the shortfall, subject to proof and mitigation.

To claim deadfreight, the Shipowner usually needs to show:

• the cargo quantity the Charterer was required to load;
• the cargo quantity actually loaded;
• the unused cargo capacity;
• the freight rate applicable to the shortfall;
• that the ship could have carried the additional cargo;
• that the Charterer had no contractual excuse for failing to load.

Deadfreight is closely connected with freight because it protects the Shipowner’s expected freight earnings. However, it is legally different. Freight is earned by carriage. Deadfreight compensates for lost freight where the Charterer fails to provide cargo.

Back Freight and Transshipment Costs

Sometimes cargo cannot be delivered in the ordinary way at the intended destination and must be carried onward, returned, transshipped, stored, or delivered at another place. In such cases, additional freight-like charges may arise, often described commercially as back freight, forwarding freight, on-carriage charges, or transshipment expenses.

If cargo is discharged at an intermediate port because of casualty, port closure, unsafe conditions, or other difficulty, the parties must determine who bears the cost of forwarding the cargo to its final destination. The answer depends on the contract, the cause of the interruption, the bill of lading terms, and the applicable law. A Shipowner may be entitled to additional compensation if the cargo owner requests carriage beyond the original contractual obligation.

Back freight may also arise where cargo is refused, misdelivered, overcarried, or sent to the wrong port. These situations are document-sensitive and can involve freight, storage, demurrage, lien, cargo claims, and sale contract issues. Clear instructions and prompt communication are essential.

Freight Payment and Bills of Lading

Bills of lading often contain freight statements. A bill of lading may state “freight prepaid,” “freight payable as per charter party,” “freight payable at destination,” or similar wording. These statements can affect the rights of the Carrier, shipper, consignee, and bill of lading holder.

If the bill of lading states that freight is prepaid, a consignee may rely on that statement and resist a later freight demand. If the bill of lading states that freight is payable at destination, the Carrier may be able to demand freight before delivery, depending on the terms. If the bill of lading incorporates the charter party, the freight terms may need to be read together with the charter party.

In chartered shipments, the relationship between the charter party and bills of lading can be complex. The Charterer may be responsible for freight under the charter party, while the bill of lading holder may have separate rights and obligations. The Shipowner should ensure that freight statements on bills of lading are consistent with the charter party and the actual payment position.

Freight Lien

A freight lien is the right to retain cargo or withhold delivery until freight or other sums are paid, if such a right exists under the contract or applicable law. The lien is commercially powerful because it gives the Carrier leverage at the moment when the cargo receiver wants delivery.

A lien for freight should be clearly stated in the charter party and bill of lading. The lien may extend to freight, deadfreight, demurrage, general average contributions, charges, expenses, or other sums, depending on wording. Without clear wording, the scope of the lien may be disputed.

Exercising a lien requires caution. The Carrier must confirm that the sum is genuinely due, that the lien covers the sum claimed, that the cargo is in the Carrier’s possession or control, and that local law permits the lien to be exercised in the proposed manner. Wrongful refusal to deliver cargo can expose the Carrier to claims. On the other hand, releasing cargo without payment may leave the Shipowner unsecured.

In some ports, practical control over cargo may pass quickly to terminals, customs authorities, receivers, or inland carriers. If the Shipowner intends to rely on a lien, notice should be given early, and local legal and agency advice should be obtained before cargo is released.

Freight Tax, Commission, and Deductions

The freight amount stated in the charter party is not always the amount the Shipowner receives net. Freight may be reduced by brokerage, address commission, freight tax, bank charges, withholding tax, currency conversion, or permitted deductions. These items should be included in the voyage estimate and addressed in the charter party.

Brokerage is commission payable to Shipbrokers involved in negotiating the fixture. It is often calculated as a percentage of freight, deadfreight, and demurrage, unless the charter party states otherwise. Address commission is often deducted by or for the Charterer and reduces the Shipowner’s net revenue. The parties should state whether commission is payable on freight only or also on deadfreight and demurrage.

Freight tax can be significant in some jurisdictions. It may be deducted from freight paid to a foreign Shipowner or Ship Operator. The tax may depend on the loading country, discharging country, flag, residence of the freight recipient, or local tax treaty. The charter party should state who bears freight tax. If it does not, the Shipowner may receive less than expected.

Deductions and set-off are frequent sources of dispute. Charterers may attempt to deduct cargo claims, despatch, alleged overpaid freight, bank costs, or other claims from freight. Shipowners often require freight to be paid in full without deduction. The contract should make the position clear. If freight is to be paid “free of discount, deduction, or set-off,” the wording may protect the Shipowner’s cash flow, subject to applicable law.

Freight and Cargo Claims

Cargo damage does not automatically eliminate freight. The Shipowner may still earn freight if the cargo has been carried and arrived ready for delivery, even if damaged. The cargo interest may bring a separate claim for damage, but the freight obligation may remain.

This separation is commercially important. If every cargo claim allowed automatic refusal of freight, Shipowners would face serious cash-flow risk. On the other hand, cargo interests need remedies for damage, shortage, contamination, or delay. The law and contract must balance these interests.

The parties should therefore decide whether cargo claims can be deducted from freight. A no-deduction clause protects the Shipowner by requiring freight to be paid first, leaving claims to be resolved later. A set-off right gives the Charterer or cargo interest more immediate protection but can create disputes over whether the claim is genuine, quantified, and legally recoverable.

Where cargo is badly damaged, the legal position may become more difficult. If the cargo is still delivered as the same commercial cargo, freight may remain payable. If the cargo is destroyed, lost, or fundamentally changed, freight may not be earned under the ordinary rule. Each case depends on the facts and contract wording.

Freight in Contract of Affreightment

A contract of affreightment may cover a series of shipments over a period rather than one voyage. Freight under such a contract may be fixed for each shipment, indexed, adjusted by formula, or negotiated within agreed parameters. The freight structure must match the commercial purpose of the contract.

In long-term cargo programs, freight clauses may include escalation provisions, bunker adjustment factors, port cost adjustments, currency provisions, and mechanisms for changing market conditions. If the contract lasts for months or years, a fixed freight rate may become unfair to one party if fuel prices, port costs, canal tolls, or regulations change dramatically.

Contracts of affreightment also require careful treatment of minimum and maximum cargo quantities. If the Charterer fails to provide cargo within the agreed program, deadfreight or damages may arise. If the Shipowner fails to nominate suitable ships, the Charterer may have a claim for non-performance. Freight is therefore part of a broader cargo program, not merely a single voyage payment.

Freight in Liner Shipping

Freight in liner shipping operates differently from freight in tramp voyage chartering. Liner services carry many shipments for many customers under published or negotiated rates. Freight may be charged per container, per unit, per weight, per measurement, or by commodity class. Additional charges may include terminal handling charges, bunker adjustment factors, currency adjustment factors, documentation fees, security charges, congestion surcharges, and equipment charges.

In liner shipping, freight is often closely connected with service reliability, schedule frequency, equipment availability, transit time, and inland logistics. The customer may pay more for faster transit, reliable service, refrigerated equipment, hazardous cargo handling, or door-to-door logistics. Freight is therefore not simply the cost of ocean carriage; it may form part of an integrated logistics price.

Electronic booking systems and digital freight platforms have made liner freight more transparent in some trades. However, freight remains affected by capacity, equipment imbalance, port congestion, peak seasons, fuel cost, alliances, regulatory changes, and trade disruptions.

Freight in Tanker and Dry Bulk Markets

In dry bulk shipping, freight commonly reflects cargo volume, ship size, route, loading/discharging speed, port restrictions, and market balance between available cargoes and available ships. Common dry bulk cargoes include iron ore, coal, grain, bauxite, fertilizers, cement, salt, sugar, steel products, and forest products. Freight rates may be quoted per metric ton or as a lump sum.

In tanker markets, freight may be quoted according to specialized market scales or as a lump sum, depending on the trade. Tanker freight is influenced by cargo type, contamination risk, tank cleaning, heating requirements, port restrictions, demurrage exposure, sanctions risk, war risk, and oil market conditions. Tanker freight calculations must also account for ballast legs, cargo compatibility, and inspection requirements.

Both dry bulk and tanker freight markets are highly sensitive to world events. A change in energy demand, grain exports, mining output, refinery margins, sanctions, canal disruption, or port congestion can quickly affect freight. Shipowners and Charterers therefore treat freight not only as a contract payment but also as a market signal.

Currency, Payment Risk, and Freight Security

Freight is usually payable in a major currency, often United States dollars. However, currency and payment risk remain important. The Charterer may be in one country, the Shipowner in another, the cargo in a third, and the paying bank in a fourth. Banking sanctions, currency controls, compliance checks, correspondent bank delays, and documentation errors can delay payment.

The freight clause should specify the payment currency, bank account, due date, value date, and responsibility for bank charges. If payment must be made before bills of lading are released, the clause should state that clearly. If payment delay gives the Shipowner a right to suspend performance, withhold documents, exercise lien, or claim interest, that should also be addressed.

In high-risk fixtures, Shipowners may require freight to be prepaid, secured by a letter of credit, guaranteed by a parent company, supported by escrow, or paid before discharge. Charterers may resist such terms because they affect cash flow. The final agreement depends on market strength, credit risk, cargo value, and bargaining position.

Interest on Late Freight

If freight is not paid on time, the Shipowner may claim interest if the contract or applicable law allows it. A freight clause may specify an interest rate for late payment. If it does not, statutory or common law principles may apply. Interest encourages timely payment and compensates the Shipowner for the loss of use of money.

Late freight can also create operational pressure. If freight is due before discharge and remains unpaid, the Shipowner may consider exercising a lien or withholding delivery. If freight is due after delivery, the Shipowner may have less leverage and may need to pursue arbitration or litigation. Payment timing is therefore a major commercial issue.

Freight and Demurrage

Freight and demurrage are different payments, but they are closely connected in voyage chartering. Freight pays for the carriage of cargo. Demurrage compensates the Shipowner for delay after laytime has expired. A voyage may be profitable because of freight alone, or it may become profitable only because demurrage is earned during prolonged port delay.

The charter party should state whether commission is payable on demurrage as well as freight. It should also state payment timing for demurrage and whether demurrage can be deducted from freight or must be invoiced separately. In some trades, demurrage claims take months to settle because they depend on statements of facts, time sheets, notices, weather records, and documentary evidence. Freight, by contrast, is usually payable earlier and with fewer factual disputes.

Shipowners should not rely on demurrage to correct a poor freight rate. Demurrage may not be earned, may be disputed, or may be reduced by exceptions. A sound voyage estimate should be profitable on realistic assumptions, not on optimistic delay expectations.

Freight and Despatch

Despatch is the opposite commercial concept to demurrage. If the Charterer completes loading or discharge faster than the allowed laytime, the Shipowner may owe despatch money if the charter party provides for it. Despatch reduces the Shipowner’s net voyage earnings, while demurrage increases them.

When calculating freight economics, the Shipowner should consider possible despatch exposure. A high freight rate may appear attractive, but if fast cargo operations generate substantial despatch, the net voyage result may be lower. The charter party should state the despatch rate, whether it applies to all time saved or only working time saved, and when it is payable.

Freight and Charter Party Forms

Standard charter party forms often contain freight clauses, but the parties frequently amend them through rider clauses. A standard form may not suit every trade. The freight clause should match the cargo, route, payment structure, bill of lading requirements, and commercial expectations.

Rider clauses should be checked against printed clauses. Conflicts between printed and added wording can create uncertainty. If a rider clause states freight is payable on shipment but the printed form suggests freight is earned on delivery, the parties may dispute which wording prevails. Usually, typed or rider clauses may prevail over inconsistent printed wording, but the safest approach is to remove contradictions before signing.

Freight clauses should also be coordinated with lien clauses, bill of lading clauses, commission clauses, tax clauses, cargo quantity clauses, and law and arbitration clauses. Freight is not an isolated provision. It interacts with the entire commercial structure of the charter party.

Freight Disputes

Freight disputes may arise from many causes. Common disputes include:

• whether freight has been earned;
• whether freight is payable on loaded or delivered quantity;
• whether prepaid freight is returnable;
• whether the Charterer may deduct cargo claims;
• whether deadfreight is payable;
• whether freight tax may be deducted;
• whether commission applies to freight, deadfreight, or demurrage;
• whether freight is payable despite damaged cargo;
• whether a lien for freight is valid;
• whether the bill of lading freight statement prevents a later claim;
• whether interest is payable on late freight.

Freight disputes are usually resolved by reference to the charter party, bills of lading, cargo documents, payment records, survey reports, port documents, and correspondence. Good documentary practice is essential. A Shipowner should preserve freight invoices, payment reminders, bank records, bills of lading, statements of facts, cargo quantity evidence, and communications about payment.

Many freight disputes are handled through arbitration because charter parties commonly contain arbitration clauses. The tribunal will examine the contract wording and the evidence of performance. The outcome often turns on precise language rather than general fairness.

Practical Drafting Tips for Freight Clauses

A professional freight clause should be clear, complete, and consistent with the rest of the charter party. It should avoid vague expressions where a precise payment obligation is needed. The parties should not rely on assumed market practice unless the wording reflects that practice.

Useful drafting points include:

• state the exact freight rate and currency;
• identify the quantity basis for freight calculation;
• state when freight becomes due;
• state whether freight is earned on shipment, loading, arrival, or delivery;
• state whether advance freight is returnable or non-returnable;
• state whether freight is payable without deduction or set-off;
• state whether deadfreight is payable and how it is calculated;
• state whether the Shipowner has a lien for freight and related sums;
• state who bears freight tax and bank charges;
• state whether commission applies to freight and other sums;
• ensure bills of lading do not contradict the charter party freight position;
• include interest for late payment where appropriate.

The best freight clauses are not necessarily long, but they must be precise. Freight disputes are often avoidable if the parties state clearly what they mean.

Commercial Importance of Freight

Freight is the economic foundation of voyage chartering. It determines the Shipowner’s revenue, influences the Charterer’s delivered cargo cost, affects commodity pricing, and reflects the balance of supply and demand in shipping markets. Freight is also a key signal for investment. When freight markets are high, Shipowners may order new ships, purchase secondhand tonnage, or keep older ships trading. When freight markets are weak, Shipowners may delay investment, scrap older ships, or lay up tonnage.

For cargo interests, freight affects competitiveness. A commodity may be profitable in one market when freight is low but uneconomic when freight rises. Grain, coal, iron ore, cement, fertilizers, and other bulk commodities are especially freight-sensitive because transport cost can represent a significant part of delivered price. Freight therefore connects shipping markets with global trade patterns.

For Shipbrokers, freight is the central negotiation point. The broker must understand not only the rate but also the payment terms, cargo basis, market direction, port risks, ship suitability, and the financial reliability of the parties. A freight rate that seems attractive may not be good if payment is insecure or deductions are likely. Conversely, a lower freight rate may be acceptable if payment is prompt, ports are efficient, and the voyage positions the ship favorably.

Conclusion

Freight is the payment earned by the Shipowner for carrying cargo under a voyage charter. It differs from hire, which is paid under a time charter for the use of the ship over a period. Freight is usually expressed as a rate per ton of cargo, but it may also be agreed as lump sum freight, minimum freight, freight on measurement, or another contractual basis.

The right to receive freight is traditionally linked to performance of the carrying service. Freight is normally earned when the cargo is carried to the agreed destination and is ready for delivery. If the voyage never begins, or if the Shipowner fails to carry the cargo to the agreed destination, no freight is payable unless the contract clearly provides otherwise. However, charter parties may modify this rule by providing for advance freight, prepaid freight, or non-returnable freight.

Freight remains payable in many cases even where the cargo arrives damaged, provided the transportation service has been substantially performed. Cargo damage claims and freight claims are not automatically the same issue. Where only part cargo is delivered, or where there is shortage or damage, the result depends on the facts and the true construction of the charter party.

Freight clauses must be drafted carefully. The parties should specify the rate, currency, quantity basis, payment timing, deduction rights, tax responsibility, commission, lien rights, deadfreight, interest, prepaid status, and bill of lading wording. Clear freight provisions protect Shipowners, Charterers, Shipbrokers, cargo interests, and receivers from avoidable disputes.

In commercial shipping, freight is more than a payment term. It is the measure of the voyage’s economic success, the basis of the Shipowner’s revenue, and a major factor in global commodity trade. Understanding freight is therefore essential for anyone involved in voyage chartering, shipbroking, cargo trading, maritime law, or ship operation.
