Thailand's TISI certification is a vital market access condition. To give you a comprehensive understanding of its latest requirements, below is a systematic overview of TISI certification's core points, latest standard changes, and certified products.

TISI Certification Core Overview:

2.Marking Requirement: Products under mandatory certification must bear the TISI mark, indicating the corresponding TIS standard number and certification number, for legal sale in the Thai market.

3.Localization Requirement: This is a key point. Foreign manufacturers must appoint a company registered in Thailand as the legal representative (certificate holder) to submit the application. Additionally, product manuals and labels must contain Thai language information.
