Standards for Trade
Last published date:


The Thai Industrial Standards Institute (TISI) is the national standards organization for Thailand under the Ministry of Industry.  TISI is a member of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).  TISI also participates in the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC).  In Southeast Asia, TISI is a member of the ASEAN Consultative Committee for Standards and Quality (ACCSQ).  TISI is also a member of the Standards and Conformance Subcommittee (SCSC) under the Asia Pacific Economic Cooperation (APEC) organization and represents Thailand in the Pacific Area Standards Congress (PASC).  Thailand follows ISO guidelines to synchronize standards with its trade partners.


TISI develops both mandatory and voluntary Thai Industrial Standards (TISs) to suit the needs and the growth of industry, trade, and economy of the country.  TISI publishes a work program every six months with its plan for standards development for Thailand.  Thai Standards are developed according to the government policy in consumer protection and industrial promotion to be competitive in the world market, environmental protection, and natural resources preservation.  There are two types of TSI product certifications with different certification marks: voluntary and mandatory certification marks. 

Use ePing to review proposed technical regulations and conformity assessment procedures

The ePing SPS&TBT platform (, or “ePing”, provides access to notifications made by WTO Members under the Agreements on Sanitary and Phytosanitary Measures (SPS) and Technical Barriers to Trade (TBT), distributed by the WTO from January 16, 1995 to present.  ePing is available to all stakeholders free of charge and does not require registration unless the user wishes to receive customized e-mail alerts.  Use it to browse notifications on past as well as new draft and updated product regulations, food safety and animal and plant health standards and regulations, find information on trade concerns discussed in the WTO SPS and TBT Committees, locate information on SPS/TBT Enquiry Points and notification authorities, and to follow and review current and past notifications concerning regulatory actions on products, packaging, labeling, food safety and animal and plant health measures in markets of interest.

 Notify U.S., operated and maintained by the National Institute of Standards and Technology (NIST) since 2003 to distribute and provide access to notifications (and associated draft texts) made under the WTO TBT Agreement for US stakeholders, has reached its end of life.  Per obligation under the TBT Agreement, each WTO Member operates a national TBT (and an SPS) Enquiry Point.   National TBT Enquiry Points are authorized to accept comments and official communications from other national TBT Enquiry Points, which are NOT part of the WTO or the WTO Secretariat.  All comment submissions from U.S. stakeholders, including businesses, trade associations, U.S domiciled standards development organizations and conformity assessment bodies, consumers, or U.S. government agencies on notifications to the WTO TBT Committee should be sent directly to the USA WTO TBT Inquiry Point.  Refer to the comment guidance at for further information.  

Conformity Assessment

The Office of National Standardization Council (ONSC) of Thailand is part of TISI that is responsible for the impartiality of accreditation activities, including certification bodies, inspection bodies, and laboratory accreditation.  Through the process of the Thai accreditation system, the Office of National Standardization Council gives formal recognition that a conformity assessment body is competent to carry out specific functions or tasks according to relevant international requirements.  TISI issues product certifications according to established Thai standards and is an accredited body for ISO and Hazard Analysis and Critical Control Points (HACCP) certifications in Thailand.

Testing, Inspection, and Certification

The Government of Thailand requires a compulsory certification of 129 products in eighteen sectors, including food, civil and construction materials, consumer goods, electrical appliances and accessories, steel, electric power, plastic, chemistry, ceramic, lighting, concrete, medical devices, rubber and rubber products, surface coatings, chemical, mechanical engineering, petroleum, and vehicles.  Certification of other products is on a voluntary basis. Industrial products that have TISI certification are generally regarded as having high standards and good quality.  Thailand is part of the ASEAN Economic Community, and as such, Mutual Recognition Agreements (MRAs) are effective for compulsory standards of certain electrical products traded between Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam.  Eligible products for MRAs must meet the International Electrotechnical Commission (IEC) or its equivalent standards.


Thailand Accreditation is operated under the National Standardization Act B.E. 2551 (2008) as one single network that includes the National Bureau of Agricultural Commodity and Food Standards (ACFS), Department of Medical Sciences (DMSc), and Department of Science Services (DSS, and Office of the National Standardization Council (ONSC)
