FOB (Free On Board)

Also known as: Free On Board, FOB delivery term

FOB is an Incoterms® rule from the family intended for sea and inland waterway transport, under which the seller delivers on board a vessel nominated by the buyer at a named port of shipment, having cleared the goods for export. Its reference point is the ship itself, which is both its precision and its constraint.

Free On Board is one of the oldest and most widely recognised delivery terms in commodity trade. The seller clears the goods for export and delivers them on board a vessel that the buyer has nominated, at a port the contract names. The buyer contracts the ocean carriage, and from the moment of delivery carries the risk of what happens to the cargo.

The term belongs to the family built around ports and vessels rather than around any mode of transport. That is what makes it precise for a cargo that is physically loaded into a ship — and what makes it an awkward fit for cargo that leaves the seller’s control at an inland depot days before a vessel is involved. Both facts are consequences of the same design decision.

What the term allocates

FOB places delivery at the vessel. The seller’s obligations run to getting the goods through export clearance and on board the ship the buyer has nominated at the named port; the buyer’s begin with having a ship there to receive them and continue through the sea leg and beyond.

Cost
The seller bears costs to delivery on board and export clearance. The buyer bears the freight, the discharge, and everything at destination.
Risk
Passes at delivery on board the vessel. Loss or damage on the sea leg falls on the buyer, whether or not the buyer has insured it.
Carriage
The buyer contracts the ocean carriage and nominates the vessel. This makes vessel nomination an obligation with real consequences: the seller cannot deliver without a ship to deliver into.
Insurance
Neither party is obliged to insure for the benefit of the other. A buyer bearing sea risk from loading arranges its own cover if it wants any.
Export and import formalities
Export clearance is the seller’s obligation; import clearance and everything at destination are the buyer’s.

Why the reference point matters

A port-based term assumes that the moment the seller relinquishes the goods and the moment they are loaded into the international carrier are close enough to be treated as one. For a bulk cargo loaded directly from a terminal into a ship’s hold, that assumption holds well: the elevator, the spout, and the hatch are all part of a single operation.

For containerised cargo it often does not hold. A container is typically handed to the carrier or terminal well before it is loaded, and the seller has no control over it in the interval. A term that fixes delivery on board therefore leaves the seller bearing risk over a period in which the goods are already out of its hands. The ICC materials discuss this distinction directly, which is why the any-mode family exists alongside the port-based one.

Context in bulk agricultural trade

FOB is deeply embedded in the language of bulk commodity trade, to the point that prices for grains and oilseeds are routinely quoted on an FOB basis at a named port. A quotation of that kind describes the value of the cargo delivered on board at that port, and it is the reference from which freight and destination costs are added to reach a landed comparison.

Loading a bulk agricultural cargo is also where several measurement and quality questions crystallise. Quantity is established at the load port by an agreed method, and sampling for quality is customarily taken during loading. What method applies, who appoints the surveyor, and whether the load-port result binds the parties are contractual questions, settled by the sale contract and the trade rules it incorporates rather than by the delivery term.

  • Bulk cargoes load directly into a nominated vessel, which is the geometry the term is built around
  • Quantity and quality are conventionally established at the load port, around the moment the term fixes as delivery
  • Vessel nomination, laytime, and demurrage are handled by the sale and charter contracts, not by the delivery term
  • The term does not address whether the cargo will be admissible at destination

What this mechanism is for

To express, in a contract of sale for waterborne transport, a division in which the seller clears the goods for export and delivers them on board a buyer-nominated vessel at a named port, with cost and risk passing at that point.

Reference, not advice

This is an educational reference description of how a trade mechanism works, not legal, customs, or contractual advice. Tariff classification, valuation, origin, and admissibility are determinations made by the competent authority for a specific consignment under the law in force at the time. Nothing here substitutes for a customs broker, a qualified adviser, or the authority’s own ruling.

  • This page describes in general terms what the rule allocates. It does not reproduce or paraphrase the rule’s text, its obligation lists, or its delivery and risk provisions.
  • Nothing here presents this rule as appropriate or inappropriate for containerised cargo, bulk cargo, or any other trade. The observation about reference points is descriptive; selection is a matter for the parties and their advisers.
  • Laytime, demurrage, vessel nomination consequences, and load-port measurement are governed by the sale contract, the charterparty, and the trade rules the parties incorporate — not by the delivery term and not by this page.

Scope & limitations

Geographic scope: Global, wherever the parties incorporate the rule and the carriage is waterborne. Port practice, load-port measurement custom, and export formalities differ by port and jurisdiction.

  • A general description of what the term allocates, not a reproduction of or substitute for the published rule.
  • No delivery point, risk-transfer moment, or obligation is stated in rule terms; those are in the ICC publication the contract names.
  • No recommendation is made about using this or any other rule for any cargo form or route.
  • Load-port measurement, sampling, laytime, and demurrage practice vary by port, trade, and contract, and no figures or timescales are given.
