Navigating TISI Certification in Thailand: A Guide to Full Regulatory Compliance for Building Materials
- Aug 8
- 3 min read
Thailand’s construction and infrastructure sectors are booming, attracting global suppliers of innovative building materials. However, entering this vibrant market requires more than just offering quality products—it demands thorough regulatory compliance, particularly with the Thai Industrial Standards Institute (TISI). This guide aims to simplify the TISI certification process and help you navigate the regulatory landscape effectively.
What Is TISI Certification?
TISI is Thailand’s national standards body, crucial in setting and enforcing product standards that ensure safety, quality, and environmental protection. The certification can be categorized into two types:
Mandatory Certification: This type is required by law for products that impact public safety. Examples include electrical components and fire-rated materials.
Voluntary Certification: While not mandatory, this certification can enhance market credibility and facilitate smoother import procedures for businesses aiming to expand in Thailand.

Who Needs TISI Certification?
Many manufacturers and suppliers need TISI certification for their products, especially those involved in:
Integrated lighting systems
Fire-resistant or load-bearing ceiling panels
Electrical components such as LEDs, ballasts, or switches
Any products used in public infrastructure or commercial buildings
Even if your products do not require mandatory certification, opting for voluntary certification can be advantageous. It will help to build trust with local Thai partners, facilitate customs clearance, and prepare your brand for any future changes in regulations.
Importing Without TISI: Is It Possible?
Yes, it is possible to import products without TISI certification under specific conditions:
Project-based Imports: Products intended solely for a particular construction project, rather than for resale, may not require certification.
Documentation: Proper documentation, including project permits, technical specifications, and a declaration of use, must be provided.
Non-mandatory Listings: If your product is not listed under mandatory TISI standards, it may qualify for import without certification.
However, be aware that customs may still demand technical documentation. The absence of certification could lead to essential delays or restrictions during the import process.

Full TISI Certification Process: Step-by-Step
At AD ASIA Consulting, we guide clients seamlessly through the TISI certification journey. Here’s a breakdown of the process:
1. Product Classification
The first step is to classify your product correctly. We will assess whether your product falls under mandatory or voluntary standards by reviewing:
The type and function of the product
Electrical or structural components involved
The intended use (whether it is for commercial, residential, or public infrastructure)
2. Document Preparation
Once classified, we move on to gathering and preparing all required documents. This includes:
Technical specifications
Safety and performance test reports
Details of the manufacturing process
Product drawings and manuals
This stage is crucial as the TISI requires comprehensive documentation to evaluate your product effectively.
3. Application Submission
Next, we will submit your application to TISI and manage all communications. This process ensures that:
All forms and formats are correct
Timely responses are given to any queries
You can track the status of your application effectively
4. Product Testing
Should testing be required, we coordinate this with TISI-accredited laboratories in Thailand. Testing may include:
Electrical safety tests
Fire resistance tests
Structural integrity evaluations
Proper testing ensures that your products will meet all required safety and performance standards.
5. Factory Audit
For specific products, a factory inspection might be mandatory. We will assist you by:
Scheduling and preparing for audits
Translating and presenting the necessary documentation
Addressing any non-conformities identified during the audit
6. Certification Issuance
Upon approval, TISI will issue a certificate that remains valid for a set period. We help you ensure:
Proper labeling and documentation for customs
Reminders for renewal and compliance updates
7. Local Representation
Foreign companies are required to appoint a local representative. AD ASIA Consulting can act as your authorized agent, ensuring ongoing compliance, facilitating communication with Thai authorities, and providing support for any future product updates or renewals.
