Trade Documents Glossary is core export documentation literacy for Trade31 operators — wrong docs delay clearance, bank payment, and delivery.
Trade Documents Glossary covers the commercial paperwork chain that proves what was sold, packed, shipped, and declared.

Use this cluster when issuing PI/CI/PL, applying for CO, aligning L/C presentations, or training new ops staff.
