Part of the Key Freight Documents Guide
A Shipper’s Letter of Instruction (SLI) is a note from the exporter to the freight forwarder with instructions on how a shipment is being sent and where it is going.
While each forwarder has their own SLI form, they all request the same details:
- Designation of consignor/consignee and their contact information
- Routing information
- Shipment dimensions and weight
- Goods description, and a UN number (if applicable)
- HS codes
Why do I need an SLI?
An SLI serves as both an order form and as proof that you are purchasing from the forwarder. It must be completed upon the pickup of your goods.
