Thailand requires ISPM-15 heat-treated (HT) wood pallets for all imports. Every wood pallet or crate entering Thailand must be heat-treated to a 56C core for 30 minutes (or fumigated) and stamped with the IPPC mark, country code TH, the producer registration number, and the treatment code. Thailand enforces this under the Plant Quarantine Act B.E. 2507 through the Department of Agriculture, with document and physical inspection at Laem Chabang and Bangkok (Klong Toey) ports. Non-compliant wood packaging is treated, re-exported, or destroyed at the importer cost.
| Requirement | What Thailand Requires |
|---|---|
| Treatment | ISPM-15 heat treatment (HT) to 56C core for 30 minutes, or methyl bromide (MB) fumigation |
| Stamp / mark | IPPC wheat-stalk logo, country code TH, registered producer number, and treatment code (HT or MB), for example TH-1234 HT |
| Governing law | Plant Quarantine Act B.E. 2507, enforced by the Department of Agriculture (DOA) |
| Main entry ports | Laem Chabang and Bangkok Port (Klong Toey); air cargo via Suvarnabhumi |
| Inspection | Phytosanitary and shipping-document review plus physical inspection of the wood packaging |
| Exempt materials | Plastic, metal, and pressed or engineered wood (plywood, OSB, processed panels) are exempt from ISPM-15 |
| Non-compliance | Treatment at port, re-export, or destruction at the importer cost, plus clearance delays |
Thailand ISPM-15 Implementation
Thailand is a contracting party to the IPPC and applies the ISPM-15 international standard for wood packaging in international trade. Thailand applies ISPM-15 through Plant Quarantine Act; Bangkok port inspection is rigorous.
Country-Specific Documentation
Thailand Department of Agriculture is the implementing authority. Per USDA-APHIS guidance for US exporters, every load to Thailand must carry: heat treatment certificate from accredited facility, IPPC stamp on each pallet, and where required, phytosanitary certificate from US plant health authority.
Common Thailand Import Issues
Common rejection causes for US-origin pallets at Thailand ports include: missing or illegible IPPC stamp, bark presence, pest residue, documentation gaps, and incorrect facility code. According to NWPCA member surveys, exporters with documented sourcing programs face fewer rejection events.
Best Practices for Thailand Exports
Best practices for shipping pallets to Thailand include: source from APHIS-accredited facilities only, retain heat treatment certificates, photograph pallets before loading for documentation, and engage a customs broker familiar with Thailand requirements. United States Pallets ships every export load with audit-ready documentation pre-attached electronically.
United States Pallets Thailand Export Programs
United States Pallets serves US exporters shipping to Thailand with ISPM-15 heat-treated stock from APHIS-accredited facilities, audit-ready documentation per load, JIT staging to coastal ports, and same-day expedite for vessel-window emergencies.
