How to Comply With TISI Standards When Exporting Power Cords to Thailand

1. Mandatory TISI Requirements for Power Cords

Power plugs and cords fall under Thailand’s compulsory certification list, meaning products must obtain TISI approval before import or local sale.

Required compliance covers:

• Product design

• Material specifications

• Testing procedures

• Plug dimensions

• Cable construction

• Labeling rules

---

2. TISI Testing Requirements

Products must undergo multiple laboratory tests, including:

2.1 Mechanical Tests

• Drop tests

• Plug pin bending tests

• Plug insertion force tests

2.2 Electrical Tests

• Dielectric strength

• Insulation resistance

• High-current load test

• Ground continuity test

2.3 Environmental Tests

• Aging test

• Humidity resistance

• Temperature cycling

Thailand’s tropical climate requires enhanced insulation and higher material durability.

3. Required Documentation for TISI Certification

Exporters must prepare:

• Technical drawings

• Cable construction charts

• Material specifications

• Factory quality-control system documents

• Sample test reports

Factories with existing UL/VDE/PSE systems typically pass TISI more easily.

4. Importer Requirements in Thailand

Thai importers usually require:

• Certificate of Conformity (CoC)

• Manufacturing license

• TISI mark authorization

• Original test reports

Reliable manufacturers like Toong Yean already follow strict production standards that align with TISI requirements.

5. Tips for Exporters Entering the Thai Market

• Use flame-retardant PVC or rubber materials

• Ensure accurate conductor size

• Use TISI-approved plug molds

• Label packaging according to Thai customs requirements

• Maintain consistent product quality

Conclusion

TISI certification is essential for all power cords entering Thailand. Manufacturers must follow strict material, structural, and testing requirements to ensure compliance. A reliable factory with multi-standard production capability will have a major advantage in Thailand’s regulated market.
