The Thailand Industrial Standards Institute (TISI) oversees the mandatory certification system under the Industrial Product Standards Act. This ensures that imported and locally produced goods meet Thailand’s national safety and quality standards.
Certification Nature:
TISI certification is categorized into Mandatory and Voluntary schemes.
→ You must first confirm whether your product falls under the mandatory list before importing or selling in Thailand.
Marking Requirement:
Products under the mandatory scope must display the TISI Mark, including the TIS standard number and certification number, before being legally sold in Thailand.
Localization Requirement:
Foreign manufacturers must appoint a Thai-registered company as their local representative (certificate holder) to submit the application.
→ Additionally, product labels and manuals must include Thai language content.
TISI regularly updates or expands the list of controlled products based on new technologies and market safety needs. Below are the latest standard updates as of the second half of 2025:
Newly Added Mandatory Certification Categories
Certain product types (e.g., power tools, smart appliances, low-voltage electronics) have been added to the mandatory list — meaning certification is required for import or sale from the official enforcement date.
Standard Upgrades
Existing TIS standards have been updated to include:
Enhanced safety requirements (e.g., electrical shock and fire risk protection).
Improved energy efficiency benchmarks.
Revised test methods aligned with international IEC standards.
Compliance Reminder:
Manufacturers and importers must ensure products comply with the latest version of applicable TIS standards before applying for certification.
TISI has long enforced certification across a wide range of industrial and consumer goods. Common product groups include:
Electrical & Electronic Equipment:
Household appliances
Power cables and plugs
Lighting and LED lamps
Bluetooth and Wi-Fi devices
Automotive Components:
Tires, safety belts, and glass components
Electrical charging equipment for EVs
Construction Materials:
Cement, steel bars, PVC pipes
Consumer Products:
Helmets, toys, pressure vessels
Each product is linked to a specific TIS standard number and compliance must be verified through TISI-approved laboratories before certification.
To achieve faster certification and avoid rejections, follow these best practices:
Early Product Classification:
Check the TISI controlled product list and confirm applicable standard versions before production.
Technical Document Preparation:
Ensure all test reports, technical drawings, and manuals are complete and translated into Thai.
Local Representative Authorization:
Appoint a qualified Thai local company to act as your legal applicant for submission and future surveillance.
Post-Certification Maintenance:
Follow annual surveillance requirements.
Update certificates after design or supplier changes.
Keep product labeling consistent with certification data.
Non-Compliance Penalties:
Selling or importing uncertified products can lead to:
Fines or seizure of goods
Revocation of import licenses
Criminal penalties for severe violations
✅ Risk Mitigation:
Monitor new TIS standard announcements.
Partner with professional consultants familiar with Thai regulations.
Conduct pre-testing before applying officially.
TISI certification is Thailand’s core regulatory gate for foreign manufacturers. To ensure smooth market access in 2025 and beyond, companies should:
✅ Confirm mandatory scope and standards early.
✅ Appoint a licensed local representative.
✅ Prepare Thai documentation and product labeling.
✅ Maintain ongoing compliance with updated TISI standards.
Q1: Is TISI certification mandatory for all products sold in Thailand?
A1: No. Only products listed under the Mandatory Certification List require TISI approval. However, voluntary certification can help improve consumer trust and brand reputation.
Q2: Can foreign manufacturers apply directly without a Thai company?
A2: No. Only a company registered in Thailand can act as the certificate holder or local representative.
Q3: How long does the TISI certification process take?
A3: On average, 2–4 months, depending on testing complexity, document quality, and the product category.
Q4: Can I use IEC or CB test reports to support the TISI application?
A4: Yes, but reports must be supplemented with Thailand-specific differences and translated documents.
Q5: What happens if my product standard is updated after certification?
A5: You must update your certification within the transition period specified by TISI, usually 6–12 months.
