Rotation Restriction

Rotation Restriction is a term in international trade transportation, referring to the restriction imposed by a carrier (such as a shipping line) on the rotation sequence of containers or cargo for different ports of call on the same route during stowage. It usually occurs when the buyer designates a freight forwarder or shipowner. To prevent cargo for different consignees from being wrongly discharged at the same port, or to meet special operational requirements of certain ports (such as draft restrictions or berth sequence), the shipping line may require the shipper to load cargo in a specific order, meaning that a certain batch of cargo can only be stowed in specific slots or can only arrive with a specific voyage. Usage scenarios are mostly seen in FOB exports where the buyer designates the shipping line, or when a letter of credit requires submission of a shipping line certificate. Precautions: violating the rotation restriction may lead to cargo being rolled, port congestion, or extra charges; the seller should confirm with the freight forwarder before booking whether it applies and keep written instructions. Unlike 'port of loading/discharge restrictions' and 'transshipment restrictions,' rotation restriction emphasizes the sequence constraint among multiple ports of call within the same voyage, rather than simply prohibiting loading or discharge at a certain port.
