FOB, or Free On Board, is an Incoterms 2020 rule for sea and inland waterway transport. The seller delivers when the goods are on board the vessel nominated by the buyer at the named port of shipment, where risk transfers under the rule.

Review points before the transaction moves

  • Confirm the party responsible for the delivery obligation.
  • Keep the source data and approval with the transaction.
  • Record exceptions instead of silently changing the original instruction.
  • Make the downstream owner able to reconstruct what happened without an email search.

The boundary worth keeping clear

The definition matters because nearby terms can describe a different document, event or responsibility. Use FOB only when the record matches the conditions above. A familiar label attached to the wrong stage creates cleaner-looking data and worse decisions. That discipline also makes reports comparable across teams, systems and reporting periods.

The trade-off

More controls add work at the start. That cost is visible. The cost of weak records arrives later as rework, delayed approval, margin leakage, a payment investigation or a delivery dispute. Set the control depth according to the amount, risk and reversibility of the decision.
