Automotive & Parts — Thailand

Thailand implements a classified mandatory certification system for market access of motor vehicles and their components. Whole vehicle certification is supervised by Thailand's Department of Land Transport (DLT), while component certification is supervised by the Thai Industrial Standards Institute (TISI). As a contracting party to the UN WP29 1958 Agreement, Thailand adopts a model combining international certification and local testing, recognizes UN ECE/WVTA certification results, and pure electric vehicles are exempted from the emission certification process.

Motor Vehicle Act: Governs type approval of whole vehicles including passenger cars, light trucks and motorcycles Land Transport Act: Governs type approval of large passenger buses and cargo vehicles Industrial Product Standards Act: Authorizes TISI to be responsible for industrial product standardization and mandatory certification management Consumer Protection Act: Clarifies energy-saving labeling requirements for motor vehicles. The technical framework mainly references the UN ECE series regulations of the United Nations, and TIS series standards are implemented locally.

Whole Vehicle: Must comply with UN ECE safety regulatory requirements, complete local emission testing (exemption for pure electric vehicles), and pass DLT's whole vehicle static inspection, braking test and safety device inspection; M1/N1 category vehicles are required to affix the ECO Sticker energy-saving label, and electric vehicles need an additional special marking. The label is the basis for consumption tax collection and subsidy application. Components: Glass, seat belts, and emission-related components fall under the mandatory TISI certification scope; tires, seats, etc. are subject to voluntary certification; components exported together with complete vehicles can be recognized with a valid E-mark certificate, and after-sales replacement spare parts must meet TIS standards and obtain TISI certification; TISI certification is long-term valid, and the original certificate will automatically become invalid if the standard is updated.
