Conformity Assessment>

The National Standardization Council (NSC) of Thailand is the part of TISI that administers the accreditation system in Thailand.  Through the process of the Thai accreditation system, the 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 124 products in 10 sectors including: agriculture, civil and construction materials, consumer goods, electrical appliances and accessories, PVC pipe, medical, LPG gas containers, surface coatings, chemical, mechanical engineering 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.  TISI has certified more than 3,000 products on a voluntary basis.  Thailand is part of the ASEAN Economic Community, and as such, Mutual Recognition Agreements (MRAs) become effective for compulsory standards of certain electrical products traded between Thailand, Malaysia, and Singapore.  Eligible products for MRAs must meet the International Electrotechnical Commission (IEC) or its equivalent standards.
