To help you quickly understand the main new regulations for Thailand's TISI Mandatory Certification in 2025, the table below summarizes the core information. These new regulations mainly focus on the household appliance sector, involving newly added mandatory certification products and upgrades to existing certified product standards.

Detailed Interpretation & Action Guide for New TISI Regulations:
Beyond the basic information in the table, the following points of interpretation and advice can help you respond more effectively:
·Focus on Newly Added Categories: For products newly added to mandatory certification, like hot/cold water dispensers and distribution boards, it means that from October 1, 2025, they must obtain TISI certification before entering the Thai market. You need to start preparing your certification application immediately.
·Understand Standard Upgrades: For products with revised standards, the new standards often introduce new requirements in safety, energy efficiency, or testing methods. For example, the new standard for room air conditioners, TIS 2134-2565 (2022), focuses on enhanced energy efficiency requirements. You must ensure your product design complies with the latest version.
·Plan Certification Timing: Ensure certification is completed before the mandatory effective date of the product standard. Considering testing and factory audits can take weeks to months, it is advised that you immediately contact a TISI-recognized certification body to develop a certification plan based on the timeline.
Brief TISI Certification Process Introduction:
If you are unfamiliar with the TISI certification process, here is a brief overview:
1.Application & Testing: Submit the application to TISI or a recognized body and send samples to an accredited laboratory for testing.
2.Factory Inspection: This is a mandatory step. TISI officials or designated bodies audit the factory's quality management system.
3.Certification & Marking: Upon successful evaluation, receive the certification certificate. Products must bear the TISI mark with a unique certification number.
4.Post-Market Surveillance: During the certificate's validity period (typically 3 years), annual surveillance audits are required to maintain validity.
⚠️Important Reminders:
·Local Representative Requirement: Foreign manufacturers must appoint a company registered in Thailand as the local representative to submit the application.
·Language & Labeling: Submitted technical documents may need to be in English or Thai. Product labels and instruction manuals must contain Thai.
