Workflow

Overview

CaseMark's Shipper's Letter of Instruction skill automates the drafting of compliance-ready SLIs for U.S. international exports. It captures all critical elements—party details, commodity classifications, export control data, and EEI/AES filing authorizations—in a structured, nine-section document that aligns with commercial invoices and government filing requirements.

Drafting Shipper's Letters of Instruction manually is tedious and error-prone, requiring careful coordination of party details, commodity classifications, export control data, and filing authorizations across multiple source documents. A single mistake in an ECCN classification or AES filing designation can trigger compliance violations, shipment delays, and significant penalties.

CaseMark automates SLI drafting by extracting and organizing data from your commercial invoices, party records, and classification documents into a structured, compliance-ready format. The AI populates all nine required sections—from party tables to signature blocks—ensuring accuracy and consistency across your export documentation.

How it works

1. Upload your commercial invoices, party details, and export classification records
2. AI extracts shipment data, commodity details, and compliance classifications
3. Review the generated SLI with all nine compliance sections populated
4. Export the finalized Shipper's Letter of Instruction in your preferred format (DOCX, PDF)

Questions

What export control frameworks does this SLI cover?

CaseMark's SLI drafting skill handles ECCN classifications, ITAR/USML categories, and EAR99 designations. It documents license numbers, exemption bases, and restricted party screening results to ensure comprehensive export compliance coverage.

Does the SLI include EEI/AES electronic filing authorization?

Yes. CaseMark generates the proper EEI/AES filing section, including designation of filing responsibility (forwarder or shipper), the authorization statement, and all required data elements for electronic export information submissions.

Can I use this for shipments with multiple commodity line items?

Absolutely. CaseMark builds a detailed commodity table with per-line-item entries including descriptions, part numbers, HS/Schedule B codes, quantities, weights, and individual export control classifications for each item in the shipment.

How does CaseMark handle Incoterms and routing details?

CaseMark captures the full shipment profile including Incoterms with year designation, port of export and destination, carrier and transport mode, ship dates, insurance coverage, and any special handling or hazardous materials requirements.

Is the generated SLI legally compliant for U.S. exports?

CaseMark produces a compliance-ready SLI aligned with U.S. export regulations, including proper USPPI identification, restricted party screening documentation, and certification language. However, all generated documents should be reviewed by your compliance team before execution.

Can I cross-reference other shipping documents in the SLI?

Yes. CaseMark's SLI header section automatically cross-references related documents such as commercial invoices, purchase orders, and packing lists, ensuring traceability across your entire export documentation package.
