What is Spot Rate?
A spot rate is a freight price quoted for a single shipment or a short validity period at current market levels, as opposed to a contract rate fixed for months under a tender or service contract. In ocean freight, carriers and NVOCCs quote spot rates per container or freight unit, with surcharges such as bunker, peak season or security either listed separately or included in an all-in price. In air freight, spot rates are quoted per kilogram of chargeable weight and are often valid only for a specific flight or day. In US trades, a tariff rate increase cannot take effect earlier than 30 calendar days after publication, while decreases may take effect on publication. Published spot rate indices track these prices by trade lane and serve as benchmarks and as the basis for index-linked contracts.
Why it matters for forwarders
Spot rates react quickly to capacity changes such as cancelled sailings, port congestion or route diversions, so they can move well above or below contract levels within weeks. Forwarders use the spot market for volume surges, new lanes and customers without contracts, but must confirm validity, space commitment and which surcharges apply on the date of loading. A common loss arises when a forwarder sells a spot rate valid on the booking date while its own carrier rate is applied by a different date, such as gate-in or sailing, and the forwarder absorbs the difference. For NVOCCs in US trades, a spot price agreed with a customer must be published in the tariff or documented in an NRA or NVOCC service arrangement, and an NRA must be agreed in writing before the cargo is received. Keep a record of each spot quote and its acceptance to defend margins when carrier invoices arrive.
