TISI Certification

As an accredited testing laboratory, we’ve helped thousands of manufacturers complete safety, EMC and energy efficiency testing for their products and achieve TISI certification.

1. TISI certification

TISI stands for Thailand Industrial Standards Institute. TISI certification is mandatory for certain products and ensures that the products meet the safety electromagnetic compatibility and energy efficiency requirements set by the Thai government. EMI and EMS marks can be applied according to the customer's needs. Products entering Thailand must comply with both the IEC and TISI standards.

2. More about TISI certification

TISI certification is mandatory for power supplies, lamps, monitors, printers, routers, gateways, cameras and other electronic products.

Not sure if your product requires TISI certification? Please fill out our short form, our expert will be glad to assist further.

Required documentation varies depending on the products. For detailed required documentation on specific product, please fill out our short form, our expert will be glad to assist you further. Below are some of typical required documentation for power supplies:

  • Circuit diagram;
  • PCB layout;
  • Label;
  • List of key parts;
  • User manual
  • Technical specification;
  • Product photos;
  • Factory ISO system certificate and quality control plan, flow chart, quality manual;

TISI certification requires products to comply with the relevant standards, but also requires manufacturers to have a completed quality assurance system to maintain product compliance with the standards. In addition to product type approval testing, TISI certification process also includes factory inspection before certification and and supervision after certification.

1. Product evaluation

TISI evaluates the products according to Thai Industrial Standards (TIS) and special requirements for product certification, which can be done in one of the following three ways:

  • (1) Taking samples and having them tested by a designated laboratory
    Samples are taken by qualified TISI officials and tested by a designated laboratory, or by a laboratory accredited by the Thai Laboratory Accreditation System (TLAS) or by a laboratory accredited by TISI;
  • (2) Samples taken by factory worker and tested at the factory and monitored by TISI qualified officials
    When it is considered that the factory’s laboratory is fully equipped with specific testing equipment and qualified engineers, the test sample can be tested at the factory and monitored by TISI qualified officers;
  • (3) Inspect test reports
    Obtain a test report from a TISI accredited laboratory. However, if the test report is incomplete or differs from the corresponding certification standards and specific requirements, TISI may take samples for supplementary testing of these items.

2. Factory inspection before certification

Factory inspection is not required for imported products, only to review the quality control document. For foreign factories, inspections are required when the quality control documents are incomplete. If the factory has obtained ISO 9000 quality management system certificate, its quality control system will be exempted from review, but the certificate issuing body should meet the following requirements:

  • Has been accredited by ONAC;
  • Approved by TISI.

However, TISI may conduct supplementary reviews of these items when the factory’s quality management system is incomplete or differs from the specific requirements for product certification and the general requirements for product quality control systems.

3. Supervisory review after certification

The purpose of supervision and review after certification is to ensure that the certified products continue to meet the corresponding standards and that the factory is still capable of maintaining the quality of the certified products. The supervision and review system includes:

  • (1) Routine supervision
    The supervision can be carried out by supervision of the quality control system and/or quality of certified products. The frequency of supervision is based on the consistency of the quality control system of the holder and the previous supervision.
  • (2) Supervision of quality control system
    Sampling test will be carried out for samples taken from factory or market by TISI qualified officers and tested by designated laboratories or laboratories accredited by Thailand Laboratory Accreditation System (TLAS) or TISI approved laboratory.

Note: Manufacturers, importers, and sellers are under supervision without prior notice to ensure that products are manufactured and sold in compliance with TISI standards and to prevent the abuse and misuse of the certification mark and any violation of the Industrial Products Standards Act and its amendments.

Below are the general application steps for achieving TISI certificate. Have questions or not sure where to start? Please fill out our short form, our expert will be glad to assist further.
