Thailand TISI Certification is administered by the Thai Industrial Standards Institute (TISI), under the Ministry of Industry. TISI operates both mandatory and voluntary product certification schemes to ensure products meet Thai Industrial Standards (TIS) for safety, quality, and performance.
TISI mandatory certification applies to products specified in the mandatory standard list, typically products that may impact consumer safety, health, or the environment. These products must obtain TISI certification before they can be imported, sold, or distributed in Thailand.
TISI voluntary certification covers products not on the mandatory list but where manufacturers wish to demonstrate compliance with Thai standards. The TISI quality mark helps build consumer trust and provides competitive advantage in the Thai market.
The certification process follows "Type Test + Factory Quality System Assessment + Post-Certification Surveillance." TISI-designated laboratories conduct product testing, and TISI inspectors perform factory assessments to ensure consistent product quality.
