Executive summary
- A voyage charter moves a cargo from point to point.
- A time charter gives commercial use of a ship for a period of time.
- A COA secures transport capacity for a programme of shipments (i.e. multiple voyages) without necessarily linking it to a specific ship.
- A bill of lading connects carriage with sale, finance and delivery. It is a document of title and, in a way, represents the goods, which allows for them to be sold in transit.
- A sea waybill speeds up straightforward delivery where documentary control is unnecessary.
- A ship’s delivery order allows one bulk cargo to be divided downstream.
- A through or multimodal document extends the sea bargain into a wider logistics chain.
Introduction: contracts of affreightment and the commercial choice
2-001 A shipment usually sits on a stack of contracts
A typical movement of grain, fertiliser, coal, ore, sugar or oil products may involve a sale contract, one or more charterparties, bills of lading, port arrangements, insurance and bank documents. English shipping law matters to traders because it provides the language through which those contracts are fitted together. This chapter focuses on the main shipping documents in that stack and explains what commercial job each of them is meant to do.
2-002 Contract of affreightment is the umbrella concept
English law uses the broad idea of a contract of affreightment to describe an agreement under which goods are to be carried by sea, or a ship is to be provided for that purpose, in return for payment. That broad category is wider than the everyday distinction between charterparties and bills of lading. For trading purposes, it is better to treat the phrase as the umbrella and then ask which specific tool the parties have chosen underneath it.
2-003 Four questions usually decide the commercial choice
First, does the trader want carriage of one cargo, a stream of cargoes, or commercial use of a ship for a period? Secondly, who should pay bunkers, port charges and cargo-handling costs? Thirdly, who should bear waiting time and other delay risk? Fourthly, does the cargo need to be sold, financed or otherwise controlled while still afloat? Those questions are usually more useful than abstract definitions because they take the trader directly to the contract form that best matches the deal.
The voyage charter
2-004 The voyage charter is the classic bulk-carriage point-to-point contract
Under a voyage charter, the owner agrees to carry a named cargo on a named voyage in return for freight. The owner keeps possession and navigation of the ship. The charterer does not hire the vessel’s earning capacity for a period; the charterer buys performance of a carriage task. This is why the voyage charter remains the natural instrument for a single parcel or a single stem where the trader wants one movement done, not ongoing control of tonnage.
2-005 Voyage charters allocate delay risk in a very distinctive way
In a voyage charter, the freight bargain is usually built on the assumption that the ship will have a defined period for loading and discharging. Laytime, demurrage, dispatch, notice of readiness and deadfreight therefore move to the centre of the commercial bargain. For a trader, that has immediate consequences. A cheap freight rate may become expensive if congestion risk sits with the cargo side. Equally, a familiar sale clause can become dangerous if it does not match the charterparty’s laytime machinery.
2-006 Traders use voyage charters when they want precision rather than flexibility
A trader fixing one wheat cargo from one Black Sea port to one Mediterranean port will often want the economics of that single trip priced and documented cleanly. The voyage charter is well suited to that model. It can also work for back-to-back trading chains where the trader expects the cargo to move under a single freight bargain and wants the owner, not the trader, to manage navigation and ship operation. The price for that simplicity is reduced flexibility once the voyage has been fixed.
The time charter
2-007 The time charter buys commercial use of the ship over time
A time charter is a different bargain. The owner still provides the vessel, crew and navigational management, but the charterer pays hire for a period and obtains the right to direct the ship’s commercial employment within the contractual limits. In trader language, the time charter buys access to carrying capacity over time rather than one point-to-point carriage task. That distinction matters because the charterer gains commercial freedom, but also assumes wider market exposure and a larger share of operational cost risk.
2-008 Time charters suit programmes, optionality and market movement
International trade works on shipping goods from places where they are available to places where they are needed most. A trading house with repeated cargoes over several months may prefer a time charter because it gives room to decide later which cargo will move next, from which port, and to which destination within the agreed limits. It also means the charterer commonly takes on hire exposure, bunkers and many port-related expenses. A trader who time-charters a vessel is no longer simply buying transport. The trader is managing a mobile business asset for the duration of the fixture.
2-009 Employment and navigation must not be confused
One of the recurrent legal themes in time charter disputes is the line between the charterer’s right to give orders about employment and the owner’s continuing responsibility for navigation and safety. For commercial users, the practical lesson is straightforward. A time charter gives real control, but not total control. The trader can direct the ship’s business use within the charter terms, yet the owner and master still retain core navigational functions. That boundary becomes important whenever routing, speed, safety and cargo orders may be in conflict.
2-010 A time charter is not a demise charter
This matters because non-specialists sometimes speak as if a time charter were a lease of the vessel. Under English law it is not. Possession stays with the owner. That affects who remains carrier under bills of lading, who answers for the crew and navigation, and why a time charterer’s liabilities do not simply mirror those of an owner. For commodity traders, the practical conclusion is that a time charter expands commercial control without turning the trader into the vessel owner in law.
2-011 Bareboat or demise charters are usually outside the trader’s core transport toolkit
A bareboat charter transfers possession and operating control of the ship to the charterer. That is closer to ship operation than to ordinary cargo trading. Commodity traders may encounter bareboat structures in the background, especially in group arrangements or long-term projects, but they are rarely the main carriage contract through which an ordinary cargo parcel is moved.
Contracts of affreightment (COA)
2-012 The contract of affreightment in the narrower commercial sense secures capacity for a programme
Modern trading often needs something between the single-voyage precision of a voyage charter and the open-ended flexibility of a time charter. A contract of affreightment, often called a COA or tonnage contract, answers that need. It commits transport capacity for a series of shipments over a period, while leaving the carrying vessels to be nominated later. For a trader with monthly stems or recurring supply obligations, that can be the most commercially efficient structure.
2-013 COAs work well where cargo volume is predictable but vessel choice need not be fixed in advance
A refinery supply programme, a fertiliser season, or a chain of coal deliveries may require capacity to be secured months ahead without tying the trader to one named ship. That is the commercial strength of the COA. The legal drafting, however, must be handled carefully. Nomination machinery, cancellation rights, freight calculation, performance defaults and any incorporation of carriage terms become more important precisely because the deal is designed to repeat.
The bill of lading
2-014 The bill of lading as the most important transport document
For traders, the bill of lading remains the most important transport document because it does several jobs at once. It acts as a receipt for the goods shipped. It contains or evidences the contract of carriage. In negotiable form, it also operates as a mercantile document by which control over the goods can move while the cargo is still at sea. That is why bills of lading stand at the junction of carriage law, sale law and trade finance.
2-015 Bills of lading are often the real control document in a commodity deal
A cargo may be resold during the voyage. A bank may advance money against documents rather than against physical possession of the goods. Delivery may lawfully depend on presentation of an original bill. Rights of suit may move under statute from one holder to another. Those consequences explain why an apparently small documentary mistake can have very large commercial effects. A trader may still have the goods physically afloat, yet lose leverage if the documentary position has not been structured properly.
2-016 The bill is not always the whole contract between original parties
As between original shipper and carrier, the bill is often powerful evidence of the carriage contract, but it may not be the complete contract in every case. That distinction matters when traders assume that everything important must appear on the face of the bill. Sometimes it does not. The charterparty behind the bill, or an earlier booking agreement, may still matter greatly.
2-017 Straight bills are not transferrable
A straight bill names a consignee and is not generally transferable in the same mercantile way as an order bill. A straight bill still functions as a bill of lading or similar document of title for relevant purposes, and presentation requirements may still matter. A straight bill should still be distinguished from a sea waybill, as to which see below.
2-018 Carrier identity on the face of the bill matters
In chartered trades, especially under time charters, traders can easily assume that the vessel owner must necessarily be the carrier or, conversely, that the charterer issuing the document must necessarily be the carrier. English law is more exacting than that. The bill must be read carefully, and the face of the document matters greatly. That is why poorly drafted signature boxes and inconsistent carrier wording still generate expensive disputes.
The sea waybill
2-019 The sea waybill trades control for speed
A sea waybill is usually the right instrument where the buyer is fixed, the cargo is not expected to be traded in transit, and the parties want to avoid the delay and inconvenience of moving original bills around the world. It is a receipt and evidence of the carriage contract, but it is not a negotiable transport document and does not provide the same documentary control over delivery as a bill of lading. It is efficient, but commercially narrower.
2-020 Sea waybills are often sensible for stable relationships and poor for trading chains
If the shipment is between related companies, or between commercial partners who do not expect any resale afloat, a sea waybill may save time and trouble. But where the seller wants to keep documentary control until payment, or where a bank expects traditional bill of lading security, a sea waybill may strip away exactly the leverage the trader needs. Choosing a waybill in the wrong deal can therefore be more than an administrative mistake. It can change the commercial balance of the transaction.
Ship’s delivery orders
2-021 The ship’s delivery order is the practical document for splitting bulk cargoes
Commodity cargoes are often sold onward in parcels after shipment. One bulk cargo loaded under one bill of lading may by discharge time represent several onward trades. The ship’s delivery order allows that bulk parcel to be broken down operationally and legally. In the right case it is the sensible bridge between one original shipment and multiple downstream deliveries. Traders working with part-cargo sales should therefore treat delivery-order mechanics as a core issue, not a port-side detail.
Through and multimodal transport documents
2-022 Through and multimodal transport documents matter whenever the trader buys a logistics chain rather than only a sea leg
Not every commodity movement begins and ends ship-side. Bagged products, containerised commodities, inland-origin metals and project cargoes may travel under one broader transport arrangement covering road, rail, terminal and sea stages. In that setting, the trader may contract with a freight forwarder or multimodal operator rather than directly with the ocean carrier. The legal question then becomes not only how the sea leg works, but who assumes responsibility across the entire chain and on what terms.
2-023 Integrated logistics can simplify operations and complicate liability
From a trading perspective, the attraction is obvious: one provider, one document and one operational interface. The legal price is that liability can become more complicated. Some documents create a genuine through-responsibility regime; others leave each stage to its own carrier or subcontractor. A trader who assumes that a multimodal document automatically gives one-stop liability may discover otherwise only after a loss occurs inland or during terminal handling.
Conclusion
2-024 The commercial choice should be made openly, not by habit
Many disputes are caused not by exotic legal doctrine but by using yesterday’s document for today’s transaction. A trader should decide whether the need is for one voyage, rolling capacity, floating optionality, documentary control over the goods, or a full logistics solution. Once that choice is made clearly, the contract form usually follows. Once the wrong form is chosen, later amendments and side letters often fail to repair the mismatch.
2-025 The simplest summary is also the most useful
A voyage charter moves a cargo from point to point. A time charter gives commercial use of a ship for a period. A COA secures transport capacity for a programme of shipments. A bill of lading connects carriage with sale, finance and delivery. A sea waybill speeds up straightforward delivery where documentary control is unnecessary. A ship’s delivery order allows one bulk cargo to be divided downstream. A through or multimodal document extends the sea bargain into a wider logistics chain. Traders who keep those distinctions clear usually negotiate better and litigate less.
