Free on Board (FOB) is an Incoterm rule for sea and inland waterway transport. The seller delivers the goods on board the vessel nominated by the buyer at the named port of shipment. Risk of loss or damage transfers from seller to buyer when the goods are loaded on board. The buyer bears all costs and risk from that point, including main carriage, insurance, and import clearance. FOB is one of the most widely used terms in bulk and breakbulk maritime trade.
FOB creates a clean risk transfer point: the ship’s rail (now “on board” under Incoterms 2020). For exporters, it limits liability once cargo is loaded. For importers, it grants control over carrier selection, freight rates, and insurance. Over 80% of seaborne container contracts still reference FOB, although alternative terms like FCA are recommended for containerised cargo.
Under FOB, the seller pays export handling, terminal charges and loading. The buyer pays ocean freight, insurance, discharge, and import duties. The critical moment: once the goods are on the vessel, the buyer carries all risk.
| Party | Key Obligations |
|---|---|
| Seller | Export packaging, delivery to named port of shipment, export licenses & customs clearance, loading charges, pre-carriage to port, risk until goods are onboard, commercial invoice, proof of delivery. |
| Buyer | Main carriage (ocean freight), insurance, unloading, import clearance & duties, on-carriage to final destination, cost of pre-shipment inspection (if required). |
In North American domestic freight, FOB is often split into FOB Origin (buyer assumes risk at pickup) and FOB Destination (seller assumes risk until delivery). However, under international Incoterms 2020, FOB always refers to the named port of shipment. Confusion between these frameworks leads to disputes. Below are the four common US domestic variations — but for ocean trade, stick to the Incoterms definition.
| FOB Term (Domestic US) | Ownership Transfer | Freight Payment |
|---|---|---|
| FOB Origin, Freight Collect | At origin (buyer assumes risk at pickup) | Buyer pays freight |
| FOB Origin, Freight Prepaid | At origin (buyer assumes risk) | Seller pays freight |
| FOB Destination, Freight Collect | At destination (seller bears risk in transit) | Buyer pays freight |
| FOB Destination, Freight Prepaid | At destination (seller bears risk) | Seller pays freight |
Using FOB for containerised goods is risky under Incoterms. Since containers are typically delivered to a terminal and loaded by the carrier, risk should transfer when goods are handed to the carrier at the terminal, not when loaded onto the vessel. Use FCA (Free Carrier) instead for containerised freight. FOB remains correct for bulk, breakbulk, or project cargo where seller loads directly onto the vessel.
FOB legally transfers risk only when cargo is “on board” the vessel. For container freight that rolls onto a Ro-Ro or is loaded by terminal, FCA or CIP/CIF are more suitable.
The contract must specify the exact port (e.g., “FOB Shanghai”). Without it, the seller can choose an expensive port, causing cost disputes.
If the buyer fails to nominate a vessel or cancels, the seller may incur storage or demurrage. The LOI should cover this.
Risk passes to buyer at loading, so the buyer must arrange marine cargo insurance immediately. Many small buyers skip this, leading to six-figure losses.
Seller packages goods, obtains export license, clears export customs, and delivers to the named port of shipment.
Seller loads goods onto the vessel nominated by the buyer. Risk transfers to buyer exactly at on-board moment.
Buyer pays ocean freight, insurance, and monitors cargo during transit.
Buyer handles import customs, pays duties, arranges inland transport to warehouse.
A UK importer buys garments from Bangladesh under FOB Chittagong. The Bangladeshi seller delivers to the port, clears export, and loads onto the vessel nominated by the UK buyer. Once goods are on board, the UK buyer pays ocean freight, insurance, and handles customs clearance in Southampton. If the container is lost at sea, the buyer bears the loss unless they purchased marine insurance.
| Incoterm | Risk Transfer | Seller covers main carriage? | Seller covers insurance? |
|---|---|---|---|
| FOB | On board vessel at port of shipment | No | No |
| CFR | On board vessel (seller pays freight to destination port) | Yes | No |
| CIF | On board vessel | Yes | Yes (minimum cover) |
| FCA | When goods handed to carrier at seller’s premises or terminal | No | No |
