Thailand / NBTC / TS 1035-2562
Last updated 7th October 2026 · By Vas Parshin and Anabel Amar

NBTC Technical Standard TS 1035-2562 extends electrical safety testing to every piece of 2.4 GHz and 5 GHz radio equipment going through Supplier's Declaration of Conformity (SDoC) — Bluetooth and Bluetooth Low Energy, Zigbee and other short-range devices, IoT products, and Wi-Fi transceivers and access points. Electrical safety testing under this track previously applied to Wi-Fi equipment only, under NBTC's 2019 standard TS 4001-2561; TS 1035-2562 closes that gap for the rest of the devices sharing the same bands. From 1 February 2026, an SDoC application for any of these devices must include three reports: an RF test report, a SAR report where applicable, and an electrical safety test report against IEC 60950-1, IEC 62368-1, or the Thai national standard TIS 1561-2556. Applications already lodged by 31 January 2026 are not affected.
A manufacturer that has only ever needed RF and SAR reports for a Bluetooth or Zigbee product now needs a third report before NBTC will accept the SDoC filing — and that report has to come from an ISO 17025-accredited lab, the same accreditation bar NBTC already applies to every other test report in the process. Booking electrical safety test capacity on top of RF/SAR testing, for a product line that previously didn't need it, is new lead time that a filing plan built on the old two-report assumption won't have accounted for. Products already certified before 1 February 2026 are not required to retest, but any new submission, re-certification, or product variant filed on or after that date needs the full three-report package from day one.
Thailand runs type approval through three tracks. Class A equipment — GMPCS terminals, microwave fixed links — is tested and certified directly by NBTC's own office. Class B equipment — high-power RFID, vehicle radar, maritime and aeronautical radio, land-mobile VHF/UHF — goes through NBTC certification too, but NBTC accepts a test report against an international standard (FCC or ETSI/EN) from an accredited lab rather than running its own testing. Most consumer radio products — WLAN, Bluetooth, low-power and short-range devices — fall under SDoC: a supplier self-declaration backed by accredited-lab test reports, without NBTC issuing a separate certificate. The new electrical safety requirement sits inside this SDoC track, so it lands hardest on exactly the consumer electronics and IoT makers who use it most. A local representative is required to hold and submit a Thai filing for a manufacturer with no Thai-registered entity.
Thailand's NBTC regime sits alongside a wider set of Asia-Pacific type-approval processes we track on their own separate clocks — Indonesia's SDPPI certification, Singapore's IMDA cellular rules, and Vietnam's QCVN 86 EMC requirements all move independently of Thailand's own TS 1035-2562 update. We fold the NBTC requirement into the same regional review we run for the rest of Southeast Asia, so a device programme covering more than one of these markets gets one coordinated testing and filing plan rather than a separate one per country.
Contact usFrom 1 February 2026, NBTC Technical Standard TS 1035-2562 requires an electrical safety test report alongside the existing RF test report and SAR report (where applicable) for Supplier's Declaration of Conformity (SDoC) applications covering 2.4 GHz and 5 GHz radio equipment — Bluetooth, Bluetooth Low Energy, Zigbee, other short-range devices, IoT devices and Wi-Fi transceivers. Previously, electrical safety testing under this track applied only to Wi-Fi equipment; the update closes that gap for every other device sharing the same frequency bands. Applications lodged by 31 January 2026 remain exempt.
IEC 60950-1, IEC 62368-1, or the Thai national standard TIS 1561-2556 (also written TIS 1561-2013). These are the same three standards NBTC has accepted for electrical safety since its 2019 standard NBTC TS 4001-2561.
Class A equipment is tested and certified directly by NBTC's own office (for example GMPCS terminals and microwave fixed links). Class B equipment goes through the same certification route but NBTC accepts a test report from an accredited laboratory against an international standard such as FCC or ETSI/EN (for example high-power RFID, vehicle radar, maritime/aeronautical and land-mobile VHF/UHF equipment). SDoC (Supplier's Declaration of Conformity) covers most consumer radio products — WLAN, Bluetooth, short-range and low-power devices — and is a self-declaration backed by test reports from an accredited lab, without a separate NBTC certificate.
Industry-reported average lead time for radio type approval is around 8 weeks once testing is complete, though this varies by equipment class and NBTC's own processing load. Certificates and SDoC registrations do not expire on a fixed term, provided the approved equipment is not subsequently modified.
