Key functions for traders and investors
Tariff classification and valuation
The Customs Department issues tariff binding rulings and conducts post-clearance audit on HS code classification — the primary arena for importers challenging duty assessments.
FTA rules-of-origin verification
Verifies origin certification for AFTA, JTEPA, TAFTA, RCEP, and bilateral FTA preference claims; incorrect CO form triggers back-duties with penalties.
Bonded zones, free-trade zones
Administers Customs Act Section 152 deferral warehouses, IEAT Free Zones, and EEC export-processing zones — structures that allow duty-suspended manufacturing and re-export.
IP and counterfeit seizures
Works with DIP and rights holders on border enforcement of trademarks, copyrights, and registered patents against infringing imports — a key node in Thailand's IP enforcement chain.
