Shipping Instruction (SI)
A Shipping Instruction (SI) is a document provided by the exporter to the freight forwarder or carrier with complete details of the shipment. It acts as the primary source for preparing the Bill of Lading. The SI clearly states how the cargo should be documented. Accuracy here is critical for smooth shipping.
The SI includes shipper and consignee information, cargo description, weight, volume, routing, Incoterms, and payment terms. It also specifies how the bill of lading shall be issued. Missing or incorrect data can result in documentation errors. These errors may result in delays or clearance issues.
Freight forwarders and carriers rely on the SI to create transport documents exactly as instructed. Once the Bill of Lading is issued, changes become more difficult and time-sensitive. That’s why exporters must review the SI carefully before submission. Clear instructions help avoid rework and disputes.
Overall, the shipping instruction ensures consistency between the physical shipment and its documentation. It aligns all parties on shipment details from the start. It reduces the risk of delays, penalties, or incorrect releases. And it supports a smooth documentation and delivery process.
