Regarding the costs for Thailand's TISI Mandatory Certification, this is indeed a critical part of market budgeting. It is important to note that there is no fixed "total price" for TISI certification, as costs vary significantly based on product category, risk level, testing complexity, and factory size.

The table below summarizes the main cost components and reference ranges for TISI certification as of 2025, helping you build an overall cost concept.

Thailand TISI Mandatory Certification Cost Composition & Range:

To make your budget more realistic, refer to the following **total cost estimates** based on product complexity (Note: these are total cost estimates including testing and audit fees; the official application fee is additional):

·Low-Risk Products (e.g., data cables, plugs): Total cost may range from ¥4,000 ~ ¥15,000 RMB.

·High-Risk Products (e.g., air conditioners, car tires): Due to mandatory factory audits and more complex testing, costs increase significantly, with total costs potentially around ¥15,000 ~ ¥28,000 RMB.

  Recommendations for Optimizing Certification Costs:

1.Confirm Product Category & Path Early: The first step is to determine your product's risk level and required certification model (long-term mark certification or single batch certification) by checking its Thai HS code or the TISI website. This helps quickly determine if costly factory audits or special tests are needed.

2.Leverage Existing Compliant Reports: If your product already has internationally recognized test reports (e.g., CB Report), they can be partially utilized in the TISI application, saving some testing costs, but Thai national difference tests must be supplemented.

3.Understand Certificate Validity & Maintenance: The TISI mark certification is valid for 3 years. It can be reused during this period but requires annual surveillance audits (which may include unannounced factory inspections and market sampling) to maintain validity. If the product design changes, re-certification may be needed, costing about 30%-70% of the initial certification.

⚠️Important Notes & Latest Developments:

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

2.Language & Document Compliance: All submitted technical documents need to be in English or Thai. Product labels and manuals **must contain Thai.

3.Latest Policies & Non-Compliance Risks:

·TISI has implemented a digital application system (e-TISI), improving application efficiency.

·Penalties for selling non-certified products are increasing, with potential maximum fines of 500,000 THB and product confiscation. Improper use of the TISI mark may also lead to daily fines until rectified.

We hope this detailed cost analysis and related interpretation helps you better plan your market entry into Thailand. As specific technical regulations and risk levels vary by product, it is recommended to confirm via the TISI official platform or consult a professional body before exporting.
