Thailand Industrial Standards Institute (TISI) certification is a mandatory market access requirement for products entering Thailand, ensuring compliance with Thai safety, quality, and performance standards. This article details the latest TISI certification process, timeline, costs, and compliance strategies to help you plan your certification work efficiently.

I. TISI Certification Core Information Overview:

·Regulatory Body: Thailand Industrial Standards Institute (TISI).

·Certification Nature:Mandatory Certification (for listed products) combined with voluntary certification.

·Core Requirements: Product Testing + Factory Quality Control System Assessment.

·Certificate Validity:3 years (for Mark Certification), requires annual surveillance audits.

·Localization Requirement: Foreign manufacturers must appoint a Thai local representative (certificate holder) to submit the application.

  II. Products Under TISI Mandatory Certification (Latest 2025):

1.Electronics & Electrical Appliances: Air conditioners, refrigerators, electric fans, lamps, wires & cables, plugs & sockets, lithium batteries & charging equipment.

2.Construction Materials: Cement, steel, construction glass, PVC pipes.

3.Automotive & Parts: Tires, safety glass, motorcycle helmets.

4.Other Products: Food contact materials, personal protective equipment, children's toys.

  III. Detailed TISI Certification Process (5 Key Steps):

1.Confirm Product Standards & Application Preparation:

·Confirm Applicable Standards: Check the TISI website or authorized bodies to determine the applicable Thai Industrial Standard (TIS), e.g., household appliances often use the TIS 60335 series (aligned with IEC standards).

·Prepare Application Documents:

Application Form (English or Thai).

Product Technical Files (specifications, circuit diagrams, manuals).

Factory Quality Management System Documents (e.g., ISO 9001 certificate).

Thai Local Representative Authorization Documents.

2.Product Testing:

·Testing Requirements: Conduct safety, performance, and EMC testing (depending on product category) in a TISI-recognized laboratory.

·Use of CB Reports: CB Test Reports are accepted but must be supplemented with Thai national difference tests.

·Testing Timeline: Approximately 4-8 weeks (varies with product complexity).

3.Factory Inspection (Critical Step):

·Inspection Necessity:Mandatory for initial certification, focusing on the quality management system and production consistency.

·Inspection Content:

Quality Management System Documents (quality manual, inspection records, etc.).

Calibration status of production and testing equipment.

Control of critical components and supplier evaluation records.

·Inspection Timeline: Typically 1-3 days.

·Outcome Handling:

Pass: No major non-conformities.

Conditional Pass: Requires rectification within a specified time (e.g., 3 months) and application for re-audit.

Fail: Major non-conformities exist.

4.Certification Approval & Mark Usage:

·Certificate Issuance: TISI issues the certification certificate upon successful audit.

·Mark Usage: Products must bear the TISI mark with a unique certification number (e.g., TIS XXX-XXXX).

5.Post-Market Surveillance & Maintenance:

·Annual Surveillance Audit: Once per year, includes unannounced factory inspections and market sampling.

·Change Management: Product design or process changes (e.g., hardware modifications, software adjustments) require re-evaluation, costing ~30%-70% of initial certification.

·Certificate Renewal: Apply for renewal before the 3-year validity period expires.

  IV. Certification Timeline & Cost Analysis:

1.Certification Timeline:

·Total Timeline: Typically 3-6 months.

Document Review & Testing: ~30-60 days.

Factory Inspection: ~1-3 days.

·Optimization Advice: Prepare documents in advance; use CB reports to reduce testing time.

2.Cost Composition:

  V. Key Considerations & Latest Policies (2025 Update):

1.Mandatory Local Representative:

·Foreign manufacturers must submit applications through a company registered in Thailand as the holder.

2.Language & Labeling Compliance:

·Technical documents must be in English or Thai versions.

·Product labels and instruction manuals must contain Thai.

·The TISI mark height must be not less than 5mm and show the certification number and country of origin.

3.Non-Compliance Risks:

·Selling non-TISI certified mandatory products may lead to a maximum of 2 years imprisonment or a 200,000 THB fine (approx. ¥40,000 RMB).

·Improper mark usage can result in daily fines until rectified.

4.Latest Policy Dynamics:

·2025 Standard Updates: Mandatory certification for some products (e.g., hot/cold water dispensers, distribution boards) took effect October 1, 2025; the new microwave oven standard becomes mandatory December 30, 2025.

·Digital Application: TISI has implemented the e-TISI system, improving application efficiency.

Thailand TISI certification is a core market access barrier. By understanding the process (Confirm Standards → Testing → Factory Inspection → Certification → Surveillance), planning the timeline (3-6 months) reasonably, and ensuring local agent and document compliance, companies can efficiently complete certification and seize opportunities in the Southeast Asian market.
