The Validity Period for Thailand NBTC Certification

For manufacturers seeking to market Information and Communication Technology (ICT) products in Thailand, it is crucial to understand the validity period for Thailand NBTC certification. This certification is valid permanently as long as there are no changes to the RF equipment specifications.
However, if there are changes to the equipment that affect NBTC standards and technical requirements, it need to be re-examined for compliance purposes. Modified telecommunications equipment needs to undergo re-verification and re-inspection through Class A registration, Class B certification, or SDoC.
Here are some examples of modifications that may result in re-inspection according to NBTC standards:
- Replaced transmission antenna
- Changed transmission or RF wave characteristics
- Replaced or newly added interface card
These NBTC regulate these updates to ensure that product models remain compliant with the latest Technical Standards and Specifications. Standards may be updated periodically to keep pace with technological developments and spectrum management needs.
Conclusion

The validity period for Thailand NBTC certification is permanent as long as there are no changes to the device specifications. If there are changes to the equipment that affect NBTC technical standards and requirements, they need to be re-examined through Class A registration, Class B certification, or SDoC again.
