Introduction to Thailand's Mandatory TISI Certification

TISI stands for the Thai Industrial Standards Institute, the national standards organization of Thailand.

Established under the Ministry of Industry and in accordance with the Industrial Product Standards Act (B.E. 2511), TISI is the authoritative body responsible for standard development and standardization promotion throughout Thailand.

TISI issues Thai Industrial Standards (TIS) and implements certification schemes to ensure that products distributed in Thailand comply with national standards. Upon successfUL certification, a product receives a certificate issued by TISI, a process commonly referred to as TISI Certification.

Types of Standards

TIS standards are divided into two categories:

Mandatory standards, which require the use of the TISI mandatory certification mark

Voluntary standards, which allow the use of the TISI voluntary certification mark

This document focuses on the mandatory certification mark.

Certification Process

TISI’s mandatory certification scheme follows ISO/IEC 17067 Type 5, which involves type testing, quality management system evaluation, and continuous surveillance of products during production and/or in the marketplace.

Applicants must submit product samples for type testing and pass a factory inspection before receiving certification.

There are currently four official TISI product certification bodies, all located in Thailand. Most testing laboratories, such as EEI and JETT, are also based in Thailand. Therefore, product samples must be sent to Thai labs for testing, and audits are conducted by Thai certification body representatives.

Common Mandatory TIS Standards

There are 122 mandatory TIS standards, with 42 of them covering electrical and electronic products, including household appliances, lighting, and other high-risk items.

Some frequently applied mandatory standards include:

Labeling Requirements

TISI has issued a guide known as the TIS BOOK that outlines how mandatory certification marks must be displayed. The product label must include the following information:

1.  The TISI mark and applicable standard number

2.  Manufacturer’s name or trademark

3.  Product name

4.  Model number

5.  Product specifications

6.  Manufacturing date

Additional product-specific requirements may apply. For example, power banks must include warnings, charging guidelines, operating temperature range, and recycling symbols.

QR Code Labeling Policy

On September 3, 2020, TISI introduced a new policy requiring certification labels to include a QR code, which officially took effect on January 21, 2020.
