On Board

“On Board” in shipping refers to the confirmed loading of cargo onto a vessel, aircraft, or truck. When a bill of lading is stamped or notated “On Board,” it means the goods have been physically loaded onto the named vessel on a specific date. This is not a trivial distinction. The on-board date determines when risk transfers under many Incoterms (FOB, CFR, CIF), when the seller has met their delivery obligation, and whether the shipment satisfies the documentary requirements of a letter of credit.

On Board Bills of Lading

An ocean bill of lading can be issued in two forms: “Received for Shipment” or “On Board.” A Received for Shipment bill confirms that the carrier has taken custody of the cargo, but the goods may still be sitting in the port terminal yard waiting to be loaded. An On Board bill confirms that the goods are physically on the vessel. The distinction matters enormously in trade finance.

Banks dealing with letters of credit almost always require an On Board bill of lading. The Uniform Customs and Practice for Documentary Credits (UCP 600), which governs letter of credit transactions globally, states in Article 20 that the bill of lading must indicate that the goods have been shipped on board a named vessel. A Received for Shipment bill does not meet this requirement unless it contains a subsequent on-board notation with the date of loading and the vessel name.

The On Board Notation

When a carrier issues a Received for Shipment bill of lading and the goods are later loaded, the carrier adds an on-board notation. This notation includes the date the goods were loaded, the name of the vessel, and the signature or stamp of the carrier or their agent. The on-board date becomes the effective shipment date for all purposes, including letter of credit compliance, insurance coverage activation, and Incoterms risk transfer.

Backdating an on-board notation is fraud. If goods are loaded on March 15 but the seller needs a March 10 on-board date to comply with a letter of credit deadline, pressuring the carrier or agent to backdate the bill is a criminal act in most jurisdictions. The consequences include letter of credit dishonor, cargo insurance voidance, and potential prosecution under maritime law. Carriers that knowingly issue false on-board dates risk their reputation and their P&I insurance coverage.

On Board in Air Freight

For air cargo, the equivalent concept applies through the Air Waybill (AWB). The AWB includes the flight date and flight number, which serves the same function as the on-board notation for ocean freight. When the cargo is physically loaded onto the aircraft, the AWB is considered executed. Air freight on-board confirmation is typically more straightforward than ocean freight because the time between cargo acceptance and loading is hours rather than days.

On Board and Risk Transfer

Under FOB (Free on Board) Incoterms, the seller’s risk ends and the buyer’s risk begins when the goods are on board the vessel at the port of shipment. Under CFR and CIF, risk also transfers at the on-board point, even though the seller pays for freight (and insurance under CIF) beyond that point. If the ship sinks the day after loading, the loss falls on the buyer under all three of these Incoterms, not the seller.

This means the buyer must have insurance in effect by the on-board date. A buyer who waits to activate their marine cargo policy until the vessel arrives at the destination port has no coverage for the entire ocean transit. Insurance must be placed before or at the time of loading.

Practical Considerations for Importers

Importers should request on-board bills of lading for every ocean shipment, even when a letter of credit is not involved. The on-board date establishes a clear record of when goods entered international transit, which is useful for tracking transit times, evaluating carrier performance, and supporting insurance claims if cargo is damaged during the voyage.

Freight forwarders typically provide the on-board bill of lading within 3 to 7 days after the vessel sails, once the carrier’s documentation team has processed the loading records. Sellers can request draft bills of lading before sailing and verified on-board copies after departure. For FBA import shipments, the on-board date helps sellers estimate arrival at the destination port and plan downstream prep and fulfillment center delivery accordingly.
