Table of Contents

Shipping goods across countries or even continents can be daunting for many small businesses. To ensure that everything goes smoothly, you need to be organized and have all the necessary shipping documents in order.

A shipper’s letter of instruction (SLI) is an important trade document that provides key information to the carrier and other involved parties about what is being shipped. This document will be used as a reference point at all stages of the shipment process, so it’s critical that you fill it out correctly.

In this blog post, we'll explain what an SLI is, how to fill it out, and give you a downloadable template to make things easier.

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

A shipper's letter of instruction is an indispensable shipping document that is created by the seller for the freight forwarder. It outlines what is being shipped, the origin and destination points, who is responsible for what aspects of the shipment process, what service levels are required, and what kind of payments will be accepted.

A shipper's letter of instruction serves several purposes:

  • Provides transportation and documentation instructions — it instructs the freight forwarder on how and where to send cargo
  • Provides limited power of attorney to the forwarding agent — grants the forwarding agent the ability to act on behalf of the shipper and submit Electronic Export Information (EEI) to the Automated Export System (AES)
  • Eliminates miscommunications — as written proof of instructions provided for the goods to be shipped
  • Streamlines document management — it contains all information on how the goods should be shipped from origin to destination, so instead of having separate conversations or sharing multiple documents, they can reference a single document

Having a shipper’s letter of instruction (SLI) on hand is optional but highly recommended, as it outlines what is being shipped and what is expected of the shipper and forwarder.
