Cargo Quantity

Cargo Quantity in Ship Chartering

Cargo Quantity is a central commercial term in voyage chartering because it determines how much cargo the Charterer must provide, how much freight the Shipowner expects to earn, whether the ship's carrying capacity is properly used, and whether deadfreight can arise. A cargo quantity clause is not just a number in a Charter Party. It controls risk, freight, loading planning, draft, cargo documentation, laytime, demurrage, and the final financial result of the voyage.

From a practical chartering perspective, the parties must determine the cargo quantity to be supplied according to the Charter Party. The issue is often discussed in daily chartering negotiations without detailed legal analysis, but it is one of the most important operational points in the fixture. The clause may require a fixed quantity, a quantity with a tolerance, a minimum quantity, or cargo up to the ship’s full cargo capacity. The exact wording decides whether the option belongs to Shipowners or Charterers.

A full and complete cargo normally means cargo which, when properly loaded, trimmed, and stowed, either fills the ship’s available cargo spaces or brings the ship down to her maximum lawful loading marks. Cargo spaces do not include crew accommodation, passenger areas, machinery spaces, store rooms, ballast tanks, bunker tanks, or spaces not intended for cargo. Loading cargo into unauthorized spaces may create serious customs, smuggling, safety, class, flag-state, and insurance problems.

The quantity of cargo may be expressed in several common ways:

1. 100,000 metric tons with an allowance of 5% more or less at the Owner's option (MOLOO)
2. 100,000 metric tons with an allowance of 5% more or less at the Charterer's option (MOLCHOP)
3. A minimum of 100,000 metric tons at the Charterer's option up to the ship's full cargo capacity

No Dead Freight is charged to the Charterer's Account Provided that the Minimum Quantity is Supplied (CHOPT FC NDFCAPMQS)

These examples may look similar, but they produce different legal and commercial consequences. If the option is in Owners’ option, the Shipowner or Master may decide the final quantity within the agreed range. If the option is in Charterers’ option, the Charterer may decide the final quantity within the range. If the clause is based on a minimum quantity up to full cargo capacity, the Charterer may avoid deadfreight by supplying the minimum quantity, provided the contract clearly gives that protection.

In practical terms, a 100,000 metric ton cargo with 5% more or less creates a range between 95,000 and 105,000 metric tons. Under MOLOO, Shipowners may require a quantity inside that range. Under MOLCHOP, Charterers may choose a quantity inside that range. Under a minimum quantity clause, Charterers may be obliged to supply at least the minimum but not necessarily the ship’s maximum possible intake.

Why Cargo Quantity Matters in Voyage Chartering

Cargo quantity affects almost every part of the voyage. It affects freight, deadfreight, cargo planning, draft, trim, stability, port restrictions, hold capacity, laytime, demurrage, despatch, Bills of Lading, sale contracts, and terminal operations. Shipowners want to use the ship's earning capacity efficiently. Charterers want flexibility to match cargo availability, storage, sale contracts, production, export permits, and market demand.

If Charterers supply less cargo than required, Shipowners may claim deadfreight. Deadfreight compensates Shipowners for freight lost on cargo space that should have been used but was not filled. If Charterers supply more cargo than the ship can safely load, the Master cannot be forced to accept the excess. Safety, lawful loading marks, stability, and port restrictions override commercial pressure.

Cargo quantity must also be considered together with cargo type. A dense cargo such as iron ore may bring the ship down to maximum draft before the holds are full. A light cargo may fill the holds before the ship reaches maximum deadweight. Therefore, quantity, stowage factor, cubic capacity, draft, and deadweight must all be reviewed together.

Full and Complete Cargo

A full and complete cargo is the quantity that uses the ship's cargo-carrying ability in the contractual and safe sense. It may be limited by weight, volume, draft, load line, cargo density, stowage factor, port depth, or stability. It does not mean Charterers may demand cargo beyond what the ship can legally or safely carry.

The ship’s full cargo capacity depends on deadweight capacity, grain or bale cubic capacity, cargo stowage factor, bunkers onboard, fresh water, stores, ballast condition, draft restrictions, seasonal load line, water density, stress limitations, and port requirements. A ship may have theoretical deadweight available but still be unable to load more cargo because the holds are full or because draft restrictions prevent deeper loading.

Deadweight, Cubic Capacity, and Stowage Factor

Deadweight tonnage is the total weight a ship can safely carry, including cargo, bunkers, fresh water, stores, crew, lubricants, and other weights. Cargo capacity is not the same as total deadweight because part of the ship's deadweight is used by non-cargo items. The real cargo intake depends on the ship's loading condition.

Cubic capacity refers to the cargo volume available inside the holds. Grain capacity is relevant for cargoes that flow into available spaces, while bale capacity is relevant for cargoes that do not fill all spaces tightly. Stowage factor tells the parties how much space a cargo occupies for a given weight. Heavy cargoes are weight-limited. Light cargoes are space-limited.

Ignoring stowage factor is a common mistake. A Charterer may promise a quantity that the ship cannot physically load because the cargo is too light. A Shipowner may expect more cargo than the draft permits because the cargo is too dense. Accurate cargo information is therefore essential before fixing.

What Is MOLOO in Ship Chartering?

MOLOO means "More or Less in Owners' Option." In ship chartering, MOLOO gives Shipowners the right to decide the final cargo quantity within the agreed tolerance. This is often used where final safe intake depends on the Master's calculation of draft, trim, stability, bunkers, load line, water density, port restrictions, and cargo characteristics.

If a Charter Party states 100,000 metric tons 5% MOLOO, Shipowners may require a quantity between 95,000 and 105,000 metric tons. Charterers must normally be prepared to supply any quantity properly nominated by Shipowners within that range. The nomination must still be consistent with the ship’s safe and lawful carrying capacity.

MOLOO is valuable to Shipowners because the Master may not know the final intake until close to loading. The ship’s remaining bunkers, fresh water, ballast, stores, draft restrictions, and load line zone may affect the final amount that can be safely loaded. MOLOO gives operational flexibility while keeping the quantity within an agreed commercial range.

More or Less in Owners' Option (MOLOO) Example

Assume a Charter Party provides for 10,000 metric tons of cargo, 5% more or less in Owners' option. The permitted range is 9,500 to 10,500 metric tons.

If the Master calculates that the ship can safely load 10,200 metric tons, Shipowners may nominate 10,200 metric tons because that quantity is within the MOLOO range. Charterers should supply that quantity if the nomination is properly made and the cargo can be provided.

If Shipowners ask for 10,800 metric tons, that is outside the agreed 5% tolerance. Unless Charterers agree separately, Charterers are not obliged to provide the additional 300 metric tons beyond the contractual range.

What Is MOLCHOP in Ship Chartering?

MOLCHOP means "More or Less in Charterers' Option." In ship chartering, MOLCHOP gives Charterers the right to decide the final cargo quantity within the agreed tolerance. This gives Charterers flexibility to match cargo availability, sale contract requirements, terminal stock, production schedules, storage limitations, and buyer demand.

If a Charter Party states 100,000 metric tons 5% MOLCHOP, Charterers may supply any quantity between 95,000 and 105,000 metric tons. Shipowners must normally accept a quantity within that range, provided the ship can safely and lawfully carry it and the nomination complies with the Charter Party.

MOLCHOP does not allow Charterers to force the ship to load beyond safe capacity. It also does not allow Charterers to supply less than the lower end of the range without risk unless Shipowners agree or the Charter Party contains another protective clause.

More or Less in Charterers' Option (MOLCHOP) Example

Assume a Charter Party provides for 12,000 metric tons of cargo, 10% more or less in Charterers' option. The permitted range is 10,800 to 13,200 metric tons.

If Charterers nominate 11,500 metric tons, the nomination is valid because it falls within the permitted range. If Charterers nominate only 10,000 metric tons, the nomination is below the permitted range and may expose Charterers to deadfreight or damages. If Charterers nominate 13,500 metric tons, the quantity exceeds the permitted range and Shipowners are not required to accept it unless separately agreed.

MOLOO vs MOLCHOP

The difference between MOLOO and MOLCHOP is the identity of the party holding the option. Under MOLOO, the option belongs to Shipowners. Under MOLCHOP, the option belongs to Charterers. The quantity range may be identical, but the commercial control is different.

Clause	Meaning	Option Holder	Commercial Effect
MOLOO	More or Less in Owners' Option	Shipowners	Shipowners can nominate final quantity within the agreed range
MOLCHOP	More or Less in Charterers' Option	Charterers	Charterers can nominate final quantity within the agreed range

The distinction should never be left unclear. If the recap uses abbreviations, the final Charter Party should expand them or use wording that clearly states who controls the option.

What Is Deadfreight?

Deadfreight is compensation payable to Shipowners when Charterers fail to provide the cargo quantity required by the Charter Party and the ship sails with unused cargo capacity that should have earned freight. It is a claim for lost freight on the missing cargo quantity.

For example, if Charterers agree to load 50,000 metric tons but provide only 47,000 metric tons, the shortfall is 3,000 metric tons. If the freight rate is $20 per metric ton and the Charter Party gives Shipowners the right to claim deadfreight, the basic deadfreight claim may be $60,000 before considering any saved expenses or contract-specific adjustments.

Deadfreight is closely tied to cargo quantity wording. If Charterers supply a quantity within a MOLCHOP range, deadfreight should not arise merely because the ship could carry more. If Shipowners validly nominate a quantity within a MOLOO range and Charterers fail to supply it, deadfreight may arise. If a minimum quantity clause protects Charterers, deadfreight may not be payable if the minimum is supplied.

No Deadfreight for Charterers' Account Provided Minimum Quantity Supplied

No Deadfreight For Charterers' Account Provided Minimum Quantity Supplied (CHOPT FC NDFCAPMQS) is a protective clause for Charterers. It means that Charterers should not be charged deadfreight for unused space if they have supplied the minimum quantity required by the Charter Party.

For example, assume the Charter Party provides “minimum 100,000 metric tons Charterers’ option up to full cargo capacity, no deadfreight for Charterers’ account provided minimum quantity supplied.” If the ship can load 115,000 metric tons but Charterers supply 100,000 metric tons, Charterers may not be liable for deadfreight because the agreed minimum has been supplied. If Charterers supply only 96,000 metric tons, a deadfreight issue may arise for the shortfall below the minimum.

This wording is useful where Charterers want access to the ship’s capacity but do not want to guarantee the full intake. It must be drafted clearly because abbreviations alone can create disputes.

CHOPT FC NDFCAPMQS Explained

CHOPT FC NDFCAPMQS is a compact chartering abbreviation. It may be understood as Charterers' option up to full cargo capacity, with no deadfreight for Charterers' account provided the minimum quantity is supplied. The main elements are:

1. CHOPT: Charterers' option.
2. FC: Full cargo capacity, depending on the fixture context.
3. NDFCAPMQS: No deadfreight for Charterers' account provided minimum quantity supplied.

Because abbreviations can be misunderstood, the safer practice is to spell out the clause in full in the recap and Charter Party. If a dispute later arises, clear words are more reliable than shorthand.

Cargo Quantity and Freight Calculation

Cargo quantity directly affects freight when freight is calculated per metric ton. If the freight rate is $30 per metric ton and 40,000 metric tons are loaded, freight is calculated on that quantity unless the Charter Party provides a different basis. If freight is lump sum, the total freight may be fixed regardless of final quantity, subject to the contract wording.

The Charter Party should state whether freight is based on Bill of Lading quantity, shore scale quantity, draft survey quantity, intake quantity, delivered quantity, or another measurement. Disputes can arise when shore figures differ from draft survey figures or when load port and discharge port measurements differ.

In dry bulk trades, draft surveys are common. In other trades, terminal scales or certified weighing systems may be used. The contract should identify which figure governs freight and deadfreight.

Cargo Quantity and Laytime

Cargo quantity can affect laytime if laytime is calculated by loading or discharging rate. For example, if the Charter Party provides loading at 10,000 metric tons per weather working day and the cargo quantity is 50,000 metric tons, the allowed loading laytime is five days. If the final cargo quantity is 40,000 metric tons, the allowed loading laytime may be four days.

This means that MOLOO, MOLCHOP, or minimum quantity wording can also affect demurrage and despatch. The parties should check whether laytime is based on the contractual quantity, loaded quantity, Bill of Lading quantity, or another figure.

Cargo Quantity and Draft Restrictions

Draft restrictions may prevent the ship from loading the contractual maximum quantity. Loading ports, discharge ports, river channels, tidal berths, locks, canals, and anchorages may all impose draft limits. A ship may have enough deadweight on paper but still be unable to load more cargo because the port does not permit a deeper draft.

Draft restrictions should be checked before fixing. If Charterers nominate a port that cannot accommodate the cargo quantity, disputes may arise. If Shipowners represent a ship as capable of carrying a quantity that the ship cannot load due to known restrictions, Shipowners may also face difficulty.

Cargo Quantity and Load Line Rules

Load line rules set the maximum lawful draft for the ship. The Master cannot load the ship beyond the applicable load line. The permitted mark may depend on season, zone, voyage, water density, and regulations. Cargo quantity clauses cannot override load line law.

If commercial pressure conflicts with safety, safety prevails. Neither MOLOO nor MOLCHOP gives either party the right to demand unsafe or unlawful loading.

Cargo Quantity and the Master's Role

The Master has an important role in final cargo intake. The Master considers stability, trim, draft, stress, bunkers, fresh water, ballast, port restrictions, load line, and cargo density. The Master's calculation may determine the safe quantity that can be loaded.

Where MOLOO applies, the Master’s final request may decide the cargo quantity within the agreed range. Where MOLCHOP applies, Charterers may choose the quantity, but the Master still controls safety. A Charterer’s option cannot require the Master to overload or endanger the ship.

Cargo Quantity and Bill of Lading Quantity

The Bill of Lading quantity is important for freight, sale contracts, letters of credit, customs, insurance, and cargo claims. The Bill of Lading should reflect the quantity actually loaded according to the applicable measurement method. The Master should not sign Bills of Lading for unsupported or incorrect quantities.

If there is disagreement between shore scale and draft survey figures, the parties should follow the Charter Party and issue protests where appropriate. Incorrect Bill of Lading quantities can create disputes with receivers, banks, insurers, and cargo interests.

Cargo Quantity and Draft Survey

Draft surveys are widely used to calculate bulk cargo quantity. A draft survey measures the ship's drafts, determines displacement, deducts known weights, and estimates the cargo loaded or discharged. Accuracy depends on careful readings, correct water density, accurate ballast and bunker figures, and proper calculations.

Draft survey results can be affected by swell, trim, list, mud in ballast tanks, inaccurate tank soundings, water density errors, and poor reading conditions. If quantity is commercially important, both parties may appoint surveyors.

Cargo Quantity and Shore Scale Figures

Some cargoes are measured by shore scales, belt weighers, silos, weighbridges, or terminal systems. Shore figures may be reliable where equipment is calibrated and procedures are controlled. However, shore figures may also be affected by equipment error, moisture variation, spillage, or documentation mistakes.

The Charter Party should state whether shore figures or draft survey figures are final. If the contract is silent, disputes may arise.

Cargo Quantity and Cargo Shortage

Cargo shortage occurs when Charterers cannot provide the required cargo quantity. Reasons may include production failure, stockpile shortage, weather damage, export restrictions, buyer cancellation, cargo rejection, customs problems, terminal breakdown, or market changes. Unless excused by the Charter Party, cargo shortage may create deadfreight exposure.

Charterers should avoid fixing quantities they cannot supply. Shipowners should assess Charterer reliability and cargo readiness, especially where cargo is seasonal, newly produced, or dependent on export permits.

Cargo Quantity and Cargo Over-Supply

Cargo over-supply occurs when Charterers present more cargo than the contract requires or more than the ship can load. If the quantity is within Charterers' option and the ship can safely carry it, loading may proceed. If the quantity is outside the range or unsafe, Shipowners need not accept it unless a new agreement is made.

Over-supply can create terminal, storage, documentation, and sale contract problems. If Charterers want the right to load additional cargo, the Charter Party should provide a clear maximum quantity and option wording.

Cargo Quantity and Charter Party Drafting

Cargo quantity clauses should be drafted with precision. The clause should state the base quantity, the tolerance, the option holder, the minimum quantity, the maximum quantity, deadfreight consequences, measurement basis, and any full cargo capacity wording. Abbreviations should be expanded if there is any risk of misunderstanding.

Good drafting avoids disputes. “About 50,000 metric tons” is less clear than “50,000 metric tons 5% more or less in Charterers’ option.” “Full cargo” may be unclear unless the cargo, stowage factor, draft restrictions, and minimum obligation are also understood. “No deadfreight” should clearly state when the protection applies.

Common Cargo Quantity Abbreviations

• MOLOO: More or less in Owners' option.
• MOLCHOP: More or less in Charterers' option.
• CHOPT: Charterers' option.
• FC: Full cargo capacity, depending on context.
• NDFCAPMQS: No deadfreight for Charterers' account provided minimum quantity supplied.
• DWT: Deadweight tonnage.
• SF: Stowage factor.

Cargo Quantity Checklist for Charterers

1. Confirm cargo availability before fixing.

Cargo Quantity Checklist for Shipowners

1. Check cargo quantity against ship capacity.
2. Review cargo stowage factor and cargo density.
3. Calculate safe intake before loading.
4. Check load line and seasonal restrictions.
5. Check port draft and berth limitations.
6. Confirm the effect of bunkers, water, stores, and ballast on cargo intake.
7. Ensure the Master understands the quantity clause.
8. Record quantity requests clearly.

Common Mistakes in Cargo Quantity Clauses

Common mistakes include confusing MOLOO with MOLCHOP, failing to identify the option holder, relying on abbreviations without clear wording, ignoring stowage factor, ignoring draft restrictions, assuming the ship can always load full cargo, failing to connect quantity with laytime, and omitting deadfreight consequences.

Another mistake is treating cargo quantity as a purely commercial number. Cargo quantity is also a safety and operational issue. The ship’s structure, stability, load line, draft, cargo spaces, and port restrictions all affect what can be loaded.

Conclusion: Cargo Quantity in Ship Chartering

Cargo Quantity is a key Charter Party term because it affects freight, deadfreight, laytime, draft, stability, port planning, cargo documentation, and the commercial balance between Shipowners and Charterers. The clause must clearly state whether the quantity is fixed, whether a more-or-less tolerance applies, who holds the option, and whether supplying a minimum quantity protects Charterers from deadfreight.

MOLOO gives the option to Shipowners. MOLCHOP gives the option to Charterers. No Dead Freight is charged to the Charterer’s Account Provided that the Minimum Quantity is Supplied (CHOPT FC NDFCAPMQS) protects Charterers where the contractual minimum is supplied, provided the wording clearly applies.

A cargo quantity clause should always be read together with the ship’s deadweight, cubic capacity, stowage factor, draft, load line, port restrictions, cargo readiness, freight calculation, Bill of Lading quantity, and deadfreight provisions. Clear drafting and careful operational planning reduce disputes and help both Shipowners and Charterers perform the voyage efficiently.
