  Products Under TISI Mandatory Certification & Latest Standards:

1.Main Product Categories: The scope of TISI mandatory certification covers electronics & electrical appliances (e.g., air conditioners, refrigerators, electric fans, rice cookers), lighting equipment, wires & cables, plugs & sockets, construction materials (e.g., cement, steel, construction glass, PVC pipes), automotive parts (e.g., tires, safety glass), as well as food contact materials, personal protective equipment, and children's toys.

2.2025 Standard Updates: TISI continuously updates its standards. Here are some of the latest developments:

·Newly Added Mandatory Standards: Mandatory certification for hot and cold water dispensers and distribution boards took effect on October 1, 2025; the standard for liquid heaters has been published, with an effective date pending.

·Standard Upgrades/Revisions: Standards for skin or hair care appliances, deep fat fryers, and similar appliances became mandatory on October 1, 2025; the new standard for microwave ovens (including combination microwave ovens) becomes mandatory on December 30, 2025; the energy efficiency standard for room air conditioners will become mandatory on April 4, 2026. New standards for electric irons, washing machines, and instantaneous water heaters have also been published, with effective dates pending.

  TISI Mandatory Certification Process Overview:

1.Confirm Standards & Apply: First, check if your product falls under the TISI mandatory certification list and identify the applicable standards. The application must be submitted to TISI or an authorized body and requires the appointment of a local Thai representative.

2.Product Testing: Products must be tested in a TISI-recognized laboratory. TISI accepts CB Test Reports but must supplement them with Thai national difference tests.

3.Factory Inspection: This is a mandatory and critical step. TISI officials or designated bodies review the factory's quality management system, including records for incoming, in-process, and final inspection, calibration of production and testing equipment, and control of critical components. Holding an ISO 9001 certificate may help streamline the process.

4.Certification Approval & Mark Usage: Upon successful audit, TISI issues the certificate. Products must bear the TISI mark containing a unique certification number.

5.Post-Market Surveillance: During the certificate's validity period, companies must undergo annual surveillance audits (including unannounced factory inspections and market sampling) to maintain certificate validity.

  TISI Certification Costs & Timeline:

1.Cost Composition: TISI certification costs vary significantly based on product risk level and testing complexity. Main components include:

·Application Fee: ~1,000-5,000 THB.

·Testing Fee: ~3,000-30,000 THB; complex tests (e.g., 28-day tests for construction materials) cost more.

·Factory Audit Fee: Starting from 15,000 THB.

·Annual Maintenance Fee: ~0.3%-1% of product value.

·Total Cost Reference: Low-risk products (e.g., data cables): ~¥4,000-15,000 RMB; High-risk products (e.g., air conditioners): ~¥15,000-28,000 RMB.

2.Certification Timeline: The complete process typically takes 3-6 months. Product testing itself takes about 4-8 weeks.

⚠️ Important Notes:

1.Mandatory Local Agent: Foreign manufacturers must appoint a company registered in Thailand as the local representative to submit the application.

2.Language & Labeling Compliance: Submitted technical documents may need to be in English or Thai. Product labels and instruction manuals must contain Thai. The TISI mark height must not be less than 5mm and must clearly show the certification number, country of origin, etc.

3.Non-Compliance Risks: Selling products subject to mandatory TISI certification without certification may result in high fines (e.g., 10,000 THB per day) or even imprisonment (up to 2 years).
