Thai Industrial Standards Institute (TISI) is the national standards body and certification authority in Thailand, responsible for developing, managing, and enforcing industrial standards to ensure safety, performance, and regulatory compliance. TISI provides two key types of product certification schemes, each represented by different certification marks: the voluntary certification mark and the mandatory certification mark.
The mandatory certification is applicable to a wide range of critical products that impact public safety and welfare. These include electrical and electronic devices, medical equipment, civil and construction materials, vehicles, agricultural goods, mechanical components, and food products. For products not falling under the mandatory scope, voluntary certification can be pursued as a mark of quality assurance and commitment to product standards.
TISI certification addresses requirements related to safety, electromagnetic compatibility (EMC), and energy efficiency, tailored to each product category. The TISI mark signifies a product’s compliance with Thai national standards and reinforces trust with consumers and regulatory authorities alike.
What Is the TISI Certification Scheme?
TIS Certification Mark (Mandatory) – No Specified Validity Period
Products requiring mandatory TISI certification include but are not limited to:
- Incandescent lamps
- Low-voltage distribution link fuses

Why TISI Certification Is Important for Your Business
For manufacturers or importers aiming to place industrial goods in the Thai market, TISI certification is a legal requirement for all products listed under compulsory standards. The certification process includes factory audits and product testing, both of which must be carried out by TISI-authorized inspection bodies and laboratories.
Without TISI certification, these products cannot be legally sold in Thailand. Non-compliance may lead to enforcement actions, including product bans, recalls, or financial penalties.
