What is a Shipper's Letter of Instruction (SLI)?

A shipper’s letter of instruction (SLI) is a document issued by the shipper to a freight forwarder that provides clear instructions for handling, shipping, and documenting a shipment in compliance with trade regulations.

The Fundamental Role of the SLI in Global Logistics

The shipper’s letter of instruction (SLI) plays an important role in cross-border logistics. It acts as a communication link between the shipper and the freight forwarder, setting out specific instructions to ensure the shipping process meets the shipper’s expectations. The SLI also supports compliance with international trade regulations, making it a key part of global logistics operations.

Main Components of the Shipper’s Letter of Instruction

  • Contact details: Names, addresses, and contact information of both the shipper and consignee. Accurate contact details are essential for effective communication.

  • Shipment description: A summary of the goods, including dimensions, weight, and value. This information helps determine transport methods and shipping costs.

  • Destination details: Specifies the final delivery location, allowing the freight forwarder to plan the most efficient route.

  • Export and import instructions: May include customs clearance requirements or other documentation needed for cross-border movement.

  • Special handling requirements: Notes any specific handling needs for items such as fragile or perishable goods.
     

Benefits of Using the SLI

  • Enhanced accuracy: Clearly documented instructions reduce the risk of errors during shipment.

  • Improved communication: Establishes a shared understanding between the shipper and the freight forwarder.

  • Regulatory compliance: Helps ensure all legal and customs requirements are met.

  • Cost efficiency: Accurate shipment details allow for precise cost calculation and help avoid unexpected charges.
