What Are the TISI Certification Processes in Thailand? What Are the Certifications Required for Lithium Battery Exports to Various Countries?

According to the Industrial Products Standard Act, the Thai Industrial Standards Institute (TISI) is authorized to conduct certification work in Thailand. TISI serves as the government authority for mandatory certification in Thailand, as well as a standard-setting and management organization, certification body, laboratory accreditation, personnel training and registration organization. Thailand implements a TISI certification system that combines mandatory certification and voluntary certification. For products that meet the standards, the use of the TISI logo is allowed. In addition, according to a decision of the Thai Cabinet, TISI also implements product registration as a temporary certification measure for products that have not yet been standardized.

Importance of TISI certification for battery testing

Starting from January 26, 2007, the Industrial Standards Bureau of Thailand formulated mandatory standards for single or portable rechargeable batteries composed of alkaline or non-acidic electrolytes. The standards require that battery products entering the Thai market must comply with specific norms, including form approval, testing regulations, safe operation, logos and packaging. On January 9, 2019, the Thai Ministry of Industry TISI issued new technical standards for mobile power sources (power banks), which came into effect on the same day.

TISI certification logo requirements for battery testing

The TISI certification logo for battery testing must include the following elements:

  • Product name;

  • IEC naming;

  • Battery polarity;

  • Production date;

  • Name of the manufacturer or supplier;

  • Rated capacity and voltage;

  • Method of battery disposal;

  • Charging instructions.

Before or during the TISI certificate application, the product label should not include the certification logo. After obtaining the TISI certificate, the product must include the TISI certification logo as well as the name of the certificate holder. Moreover, the merchant must affix the safety label to the product before entering it into Thailand.

TISI certification process for battery testing

The TISI certification process for battery testing is as follows:

  1. The customer provides product and importer information to ESTL, and ESTL contacts local Thai importers to collect relevant documents;

  2. The customer provides samples and testing documents. ESTL sends the samples to an accredited laboratory recognized by ThaiTIS. The laboratory arranges the testing;

  3. ESTL and the customer, as well as Thai engineers, confirm the inspection date. ESTL assists with factory inspections;

  4. ESTL follows up on the testing progress and inspection report progress. After completion of both, TISI certificates are issued.

Battery testing certifications for exporting lithium batteries to various countries in the world

CB certification

The IECEE-CB system is a globally recognized system for electrical product safety testing results established by the International Electrotechnical Commission (IEC) Certification and Testing Organization (IECEE). It achieves mutual recognition of test results for 19 categories of electrical products including batteries, household appliances, information and communication equipment, and medical electrical equipment. Currently, there are 53 countries worldwide that are members of the CB system. Multilateral agreements have been formed between the national certification bodies (NCBs) of each country, and manufacturers can obtain national certification for other CB system member countries based on a CB test certificate issued by one NCB. The CB system is based on international IEC standards. If national standards of some member countries cannot fully comply with IEC standards, differences are allowed but should be made public to other members.

UL certification

UL stands for Underwriter Laboratories, a US-based product safety testing and certification organization. UL1642 is the authoritative standard for evaluating the safety and reliability of lithium-ion batteries under various fault conditions, mainly for the cell; UL2054 is mainly for lithium-ion battery packs or batteries.

KC certification

The Korea Certification (KC) mark is a mandatory safety certification system for electronic and electrical products established by the Korea Agency for Technology and Standards (KATS) in accordance with the Electrical Appliances Safety Control Act, which began implementation on January 1, 2009. KC certification is divided into three categories: mandatory safety certification, voluntary safety certification, and self-confirmation by suppliers. Secondary lithium battery products belong to the second category and do not require factory inspections.

PSE certification

PSE is a mandatory market access system for electrical products in Japan. Japan divides electrical products into "specified electrical products" and "non-specified electrical products". Products belonging to the "specified electrical products" catalog that enters the Japanese market must be certified by a third-party certification body authorized by the Ministry of Economy, Trade and Industry, and obtain a qualified certification certificate. The rhombus PSE mark should be added to the product label. For products belonging to the "non-specified electrical products" catalog that enters the Japanese market, manufacturers must test and declare conformity to Japanese electrical product technical standards and add the circular PSE mark to the product label.
