HS Code, OGA and Import Permits: Why Cargo Gets Held at Thai Customs

Quick answer: Cargo may be held because classification is inconsistent, product descriptions are vague, valuation or origin needs review, or another government agency regulates the goods. Requirements should be checked before origin dispatch.

For new importers, procurement teams and suppliers shipping a product model into Thailand for the first time.

Information to check before starting

  • HS code based on actual product characteristics
  • Catalogue, specification, model and use
  • Required OGA permits
  • Price, trade terms and payment evidence
  • Origin and preference claims

A practical operating sequence

  1. Collect technical data before classification
  2. Align all documents
  3. Check regulator and permit conditions
  4. Run a pre-check before transport
  5. Keep the decision trail for repeat shipments

Common causes of delay and extra cost

  • Reusing a foreign HS code without Thai review
  • Ordering before knowing who can hold the permit
  • Changing descriptions only after arrival
