What is it?

Customs inspection is the authority’s review of goods and/or documents to confirm classification, valuation, origin, prohibitions, and other regulatory requirements.

Important Terms

Keep definitions operational: name places/ports, dates, document triggers, and cash milestones — avoid naked acronyms in contracts.

Why does it matter?

Exams create demurrage and missed shelves. Preparation is cheaper than terminal storage while you “find the packing list.”

How is it used?

1. Define commercial objective and constraints.
2. Map Customs inspection options to cash, risk, and documents.
3. Write chosen path into PI / contract.
4. Verify with Trade31 tools; check TradeVik for country policy.
