Complete Guide to Thailand TISI (Thailand Industrial Standards Institute) Certification
Essential for Market Access in Thailand for Electrical Products / Auto Parts / Building Materials / Consumer Goods (Mandatory Certification)
1. Understand Thailand's TISI certification
Thailand's TISI (Thai Industrial Standards Institute) is the core standardization regulatory body under the Ministry of Industry, responsible for formulating and implementing the Thai Industrial Product Standards (TIS). TISI certification is divided into mandatory certification (TISI Mandatory Certification) and voluntary certification (TISI Voluntary Certification). Products in the mandatory catalog must complete TISI certification and affix the TISI mark before being imported, sold, and used; Non-compliant products are prohibited from customs clearance and shelving; violations face hefty fines and product confiscation. Certification follows the Thai Industrial Standards (TIS) and is a core mandatory requirement for entering the Thai industrial goods market.
1.1 Which products require Thailand TISI certification?
| Category | Specific products |
|---|---|
| Electrical products | Household appliances (refrigerators/air conditioners/washing machines), power adapters, wires and cables, switches and sockets, lighting fixtures, power tools, transformers, batteries |
| Automobiles and parts | Motorcycle/car tires, brake pads, seat belts, rearview mirrors, batteries, spark plugs, headlights, exhaust systems |
| Building materials | Rebar, cement, tiles, glass, pipes, waterproof materials, aluminum alloy profiles, sanitary ware, coatings |
| Consumer goods | Toys, children's products, food contact materials, kitchenware, safety helmets, firefighting equipment, bicycles, gas appliances |
| Chemical products | Lubricants, fuel oils, adhesives, cleaning agents, plastic raw materials, flame retardants |
- Low-risk, non-regulated daily necessities (such as ordinary fabric crafts and handmade accessories) do not require TISI certification and only require routine customs clearance
- Samples intended solely for research and testing (non-sale) may apply for a temporary import license (valid for 6 months) and are exempt from TISI certification
- Non-mandatory catalog products produced locally in Thailand only require TISI filing, without the need for a complete certification process
1.2 Types of Thailand TISI certification
| Types of certification | Applicable products/scenarios | Validity period |
|---|---|---|
| Mandatory Certification | TISI mandates imported/locally produced products within the catalog | 3 years (annual supervision and review required) |
| Voluntary Certification | Non-mandatory catalog products (to enhance market recognition) | 2 years |
| Import Certification | Customs clearance certificate for each batch of TISI mandatory imported products | Only valid for the current batch of imports |
| Factory Certification | A local Thai company producing TISI mandatory products | 3 years (requires on-site factory audit) |
| Type Approval | Electrical/Automotive Products (Product Model Compliance Certification) | 5 years (model change and recertification required) |
2. Certification Process & Core Basic Information
Document preparation and preliminary evaluation
Preparation phaseConfirm whether the product is listed in the TISI mandatory catalog, organize the product technical documents, and select a local authorized representative recognized by Thailand's TISI.
Product testing and report acquisition
20-35 working daysProducts are sent to TISI-accredited laboratories in Thailand to complete tests that comply with Thai Industrial Standards (TIS) (such as electrical safety, material performance, environmental indicators), and obtain qualified test reports.
Submit your certification application online
10-15 working daysSubmit test reports, product labels, specifications, and other documents through the official TISI system and pay TISI certification fees (charged by product category/model).
Audits and factory checks (if applicable)
25-40 working daysTISI reviews the completeness and compliance of documents; local manufacturers and high-risk products (such as electrical and automotive parts) must undergo on-site factory inspections (compliant with ISO 9001 standards).
Issuance of TISI certificates and customs clearance
5-10 working daysAfter passing the review, you will receive the TISI certification certificate. Before each batch of import, you must present the TISI certificate to apply for import certification and complete customs clearance at Thai customs. The product must bear the TISI mark before sale.
