1 Overview
FOB, short for Free On Board, is one of the oldest and most familiar rules in the Incoterms family. In plain terms it says the seller delivers the goods by placing them on board the vessel the buyer has nominated, at the port of shipment the parties named in the contract. Everything before that moment is the seller's problem; everything after it is the buyer's. That sounds simple, and for bulk cargo lifted over a ship's rail it largely is. The trouble for first-time ocean shippers is that the rule was written for a world of breakbulk and bulk, while most new exporters are moving palletized or containerized cargo through a terminal.
The gap between the rule's wording and modern terminal practice is where confusion starts. A container is usually handed to a terminal or a carrier at a gate, not physically lifted onto a ship by the seller. Under a strict reading of FOB, risk does not pass at that gate; it passes only when the container is loaded on board. Sellers who assume their responsibility ends when the truck leaves their yard can be surprised to learn they still carry risk during the days the box sits at the port. Buyers, meanwhile, may think they control the shipment from the moment it is in the terminal, which is not what the rule says. Reading FOB literally, and matching it to how the cargo actually moves, prevents most of these disputes before they begin.
2 Where the risk and the cost actually land
Risk and cost do not always travel together, and FOB is a good example of why shippers must track them separately. Risk passes when the goods are on board the vessel at the named port of shipment. Cost, however, is split at the same point only for the charges the rule assigns. The seller pays for packaging, inland transport to the port, export clearance, terminal handling on the origin side as agreed, and the loading operation. The buyer pays the ocean freight, the destination terminal charges, import clearance, duty and taxes, and onward delivery. If the contract names a port but not a specific terminal or berth, the parties may disagree about which handling charges fall on which side.
The insurance position follows from the risk point. FOB obliges neither party to buy cargo insurance. In practice the buyer arranges cover from the moment of loading, because that is when its risk begins, and the seller may arrange its own cover for the inland leg and any storage before loading. A common and expensive mistake is a gap: the seller's policy ends when the goods reach the port, the buyer's policy starts only on board, and a loss during terminal storage falls between them. Another is assuming the carrier's liability substitutes for cargo insurance. Carrier liability is limited by the contract of carriage and by international conventions, and it rarely covers the full commercial value of the goods. Insurance is a private arrangement, and under FOB it is the buyer's decision to make, not an obligation the seller can rely on.
3 How the mechanics work end to end
The sequence begins with the sales contract naming FOB, the port of shipment, and often a specific terminal or delivery point. The seller prepares the goods, books inland transport, and completes export formalities, including any export licence and the export declaration. The buyer, or its agent, nominates a vessel and communicates the vessel name, loading window, and terminal details in time for the seller to deliver. The seller moves the cargo to the port and hands it to the terminal or carrier against a receipt. That receipt matters, because it is the first written evidence of where the goods were and when.
Loading is the pivot. Once the goods are on board, risk passes to the buyer, and the carrier issues an on-board bill of lading or a received-for-shipment bill of lading that is later marked on board. The seller presents the commercial invoice, packing list, bill of lading, and any certificate of origin to the buyer, often through a bank if payment is by letter of credit. The buyer then handles the ocean leg, arranges insurance, and prepares import documentation. At destination the buyer or its customs broker files the entry, pays duty and taxes, and takes delivery. Two practical points deserve attention. First, the bill of lading is a document of title in many transactions, so its form and wording affect payment as much as transport. Second, the named port must be precise; a vague reference such as a country or a range of ports leaves the delivery point undefined and invites argument about who pays the last inland mile.
4 A worked example from door to destination
Imagine a furniture maker in an inland city selling a container of chairs to a buyer overseas on FOB terms at a named seaport. The seller arranges a truck to the port, prepares the export declaration, and pays the inland freight and export clearance. The buyer nominates a vessel and a terminal. The container arrives at the terminal gate and is stacked to await loading. Under FOB, risk has not yet passed, because the goods are not on board. If a fire, flood, or theft damages the container during that waiting period, the loss falls on the seller, even though the seller no longer has physical control of the goods. This is the single most common surprise for first-time shippers.
Once the container is lifted onto the vessel, risk passes to the buyer. The carrier issues a bill of lading, and the seller presents it with the invoice, packing list, and certificate of origin. The buyer pays the ocean freight, insures the cargo from loading, and, at destination, files the import entry, pays duty and value-added tax, and collects the container. If the buyer's insurance was arranged only from the moment of loading, and the seller's cover ended at the terminal gate, the waiting period is uninsured. If the contract had instead named a precise terminal and required the seller to insure until loading, the gap would close. The lesson is not that FOB is wrong, but that its risk point must be matched to the physical journey and to the insurance each side actually buys.
5 Mistakes that cost money at the border
The first costly mistake is using FOB for containerized cargo without adjusting the delivery point. Because containers are handed over at a terminal rather than lifted over a rail, the strict risk point can leave the seller exposed for days. Parties who want risk to pass at the terminal gate should consider a rule designed for that handover, or state clearly in the contract how the terminal period is treated. The second mistake is leaving the port vague. Naming a country, a coast, or a range of ports gives the seller no defined destination and gives the buyer no defined loading point, which delays booking and can trigger demurrage or storage charges while the parties argue.
The third mistake is assuming the freight forwarder or carrier will handle customs. Carriers move cargo; they do not act as the importer of record. The buyer must file the import declaration, classify the goods under the harmonized system, and pay duty and taxes. Misclassification is a quiet and expensive error: the wrong code can mean the wrong duty rate, missing preferential treatment, or a penalty on review. The fourth mistake is documentary. A bill of lading that does not match the invoice, a missing certificate of origin, or a packing list that disagrees with the cargo description can stall payment under a letter of credit and hold the container at destination. Small inconsistencies at the border cost storage, inspection fees, and time, and they are almost always avoidable with a checklist and a second pair of eyes before documents are presented.
6 Documents worth keeping
The commercial invoice is the anchor document. It identifies the parties, describes the goods, states the Incoterm and named port, and gives the value used for customs and for payment. The packing list supports it by showing how the goods are packed, how many packages there are, and their weights and dimensions, which helps the carrier and the customs broker alike. The bill of lading is the transport contract and, in many transactions, the document of title; it should show the shipper, consignee, notify party, port of loading and discharge, and the number of packages, and it should be marked on board once loading occurs.
Around these core papers sit the origin and compliance documents. A certificate of origin can support a preferential duty rate under a trade agreement, but only if it is correctly completed and the goods genuinely qualify. The export declaration and any export licence prove that the seller cleared the goods out of the origin country. On the import side, the customs entry, duty and tax receipts, and any inspection or release notices show that the buyer fulfilled its obligations. Keep all of these for the period your jurisdiction requires, because customs audits can reach back several years. Store them together, in a form that links each shipment to its invoice, bill of lading, and entry, so that a question months later can be answered with one file rather than a search through email.
7 Frequently asked questions
Does FOB mean the seller pays the ocean freight? No. Under FOB the buyer arranges and pays the main carriage, because risk and cost pass when the goods are on board. The seller pays the costs of getting the goods to and onto the vessel, including export clearance. If the parties want the seller to pay the ocean freight, that is a different rule and should be named in the contract.
Who insures the cargo under FOB? Neither party is obliged to insure. The buyer normally insures from the moment of loading because that is when its risk begins, and the seller may insure its own pre-loading exposure. The important thing is to avoid a gap between the two policies.
Can FOB be used for containers? It can be named, but it fits containerized trade awkwardly because the handover happens at a terminal rather than on board. Parties should either choose a rule suited to terminal delivery or define the delivery point and the terminal period explicitly.
What if the named port is vague? A vague port leaves the delivery point undefined and can cause disputes over charges, delays, and risk. Always name the port, and where possible the terminal, in the contract and on the invoice.
Who clears customs? The seller handles export clearance; the buyer handles import clearance, classification, and duty. A freight forwarder can assist with paperwork but does not become the importer of record unless it is licensed and engaged to do so.
