FOB

Definition

Free On Board — an Incoterm-style shipping term indicating the point at which responsibility and risk transfer from seller to buyer, commonly specified as FOB origin or FOB destination.

Overview

FOB An Incoterm commonly used for ocean freight where responsibility transfers according to the named port and agreed FOB terms.


FOB assigns different costs and risks to seller and buyer around a clear transfer point: the named export port when goods are loaded on board the vessel. Understanding which party pays for each leg—export packing, inland carriage to port, loading, ocean freight, insurance, and import fees—prevents billing disputes and clarifies who is liable for loss or damage at every stage.


Basic Cost Allocation Under FOB


  • Seller Pays: Export packing and labelling, inland transport to the named port, export customs clearance and duties (if any), terminal handling up to loading, and costs of placing goods on board the vessel.
  • Buyer Pays: Ocean freight, sea carriage, marine insurance (if purchased), import customs clearance, duties and taxes at destination, and inland transport from the destination port to final delivery.


Risk Transfer Versus Cost Allocation


FOB separates risk and cost: risk of loss or damage shifts from seller to buyer when goods are on board at the named port, while cost liability may follow the same split but always depends on contract specifics. Parties can agree to variations, but any deviation from standard FOB obligations should be spelled out in the sales contract.


Common Billing Disputes And How They Start


Disagreements often arise over whether loading onto the vessel actually occurred, who paid for terminal charges like storage or demurrage before loading, and responsibility for short-shipped or concealed damage discovered after arrival. These disputes occur when documents (bill of lading, mate’s receipt, terminal receipts) are missing or contradictory.


Practical Steps To Avoid Cost Disputes


  • Clarify responsibilities in the contract: State who pays port handling, terminal storage, demurrage, and container detention if delays occur before loading.
  • Use precise Incoterm phrasing: Quote the full term and version, e.g., FOB Port of Los Angeles, Incoterms���� 2020.
  • Collect loading evidence: Sellers should obtain bills of lading or mate’s receipts showing 'loaded on board' status; buyers should confirm before arranging insurance and onward carriage.
  • Negotiate responsibility for terminal charges: Agree who pays storage and demurrage that result from buyer-controlled booking delays.


Example Cost Breakdown


Exporter in Savannah sells on FOB Savannah terms. Exporter pays damage-proof palletizing, drayage to the terminal, export clearance, and loading. Buyer contracts the ocean carrier and pays the ocean freight and arrival terminal fees; buyer also arranges insurance for the sea voyage. If the container sits at the terminal awaiting booking and incurs storage fees because the buyer delayed booking the vessel, the contract should state who bears those fees.


Insurance Considerations


FOB does not obligate either party to buy insurance, but because risk passes at loading, buyers commonly purchase marine insurance from that point. Sellers can offer to secure insurance as a commercial courtesy, but doing so without written agreement can create ambiguity about claims handling and premiums.


In short, the FOB Incoterm creates a clear handover at loading but does not eliminate billing disputes—those are best prevented by detailed contracts, unambiguous documentation, and agreed responsibility for terminal and delay-related charges.
