SI Cut-off Date (Shipping Instruction Cut-off)

SI Cut-off Date is a key deadline in international ocean freight export, referring to the last date set by the shipping line or freight forwarder for receiving the Shipping Instruction (SI) submitted by the shipper. The SI typically includes consignee, notify party, description of goods, marks, weight, volume, etc., and is used to prepare the Bill of Lading. The SI Cut-off Date is generally earlier than the CY Cut-off and the vessel departure date, and later than the Gate Cut-off. If the SI is not submitted or amended before the SI Cut-off Date, the shipping line may refuse changes, resulting in B/L errors, amendment fees, late declaration charges, or even affecting customs clearance at the destination port. Usage scenarios: document flow between shippers, freight forwarders, and shipping lines, especially under FOB shipments where overseas agents often require strict compliance with the SI Cut-off Date. Notes: The SI Cut-off Date is different from the CY Cut-off, which is the last time containers must enter the terminal; the SI Cut-off Date only concerns documents. In addition, SI Cut-off Dates may vary by shipping line, route, and port, and may be advanced during holidays, so always confirm in writing with the freight forwarder. Difference: SI Cut-off focuses on documents, CY Cut-off focuses on cargo, and Gate Cut-off focuses on gate-in; the three must not be confused.
