A shipper's letter of instruction, or SLI, gives a freight forwarder or agent the shipper's directions and data for arranging an export shipment. It can also document authorization to prepare or submit specified export information.
What information can an SLI contain?
- Exporter, consignee and intermediate consignee
- Shipment route and transport method
- Commodity description and classification
- Quantity, value, weight and origin
- Export-control and license information
- Freight payment and document instructions
Is an SLI a transport document?
No. It instructs the forwarder and supports export processing. A bill of lading, air waybill or other carrier document evidences the transport arrangement.
Who is responsible for accuracy?
The exporter or authorized party remains responsible for accurate information and authority, even when a forwarder prepares filings. Responsibilities should be stated clearly.
What errors create risk?
Incorrect classification, value, consignee, license or routing can delay shipment and create compliance exposure. The final carrier and export records should be checked against the approved instruction.
How should it be controlled?
Use an approved version, authorized signer, secure transfer and record retention. Amend instructions formally rather than relying on disconnected emails.
