Determining the correct HS classification is a very important step in the import process. Under World Customs Organization rules, member countries use the same first six digits of an HS code, while later digits are determined by each country individually. Both Vietnam and Thailand currently apply the eight-digit ASEAN Harmonized Tariff Nomenclature (AHTN).

Enterprises must rely on the detailed description of the imported goods to classify them accurately under Thai regulations. If uncertain, they may contact the Thai Customs Department for advance classification assistance.

Accurate classification is important not only for customs declaration purposes but also for declaring origin on certificates of origin when goods seek preferential tariffs under FTAs to which both Vietnam and Thailand are parties, including ATIGA, ASEAN+ FTAs, and RCEP.
