NBTC Certification for Wi-Fi Routers & Access Points

Wi-Fi routers and access points sold or imported into Thailand require NBTC certification before they can be placed on the market. For most products, the applicable path is a Supplier's Declaration of Conformity (SDoC). The only exception is products operating in the 5725–5850 MHz band under the Long Term Evolution (LTE) condition, which require Class A registration.

What Counts as a Wi-Fi Router or Access Point?

For NBTC certification purposes, this category covers any device that transmits wirelessly using IEEE 802.11 standards and is intended for network access. This includes home Wi-Fi routers (single-band, dual-band, tri-band), commercial and enterprise access points, mesh network nodes and range extenders, Wi-Fi modules embedded in gateways and smart home hubs, and industrial wireless access points.

If your product includes additional radio technologies such as Bluetooth or cellular, those interfaces are covered under separate NBTC applications. Zergo will identify all applicable applications and submit a single combined certification.

Certification Requirements

The 2.4 GHz and 5 GHz bands are governed by NBTC TS 1035-2562. The 6 GHz band (5925–6425 MHz) is governed by NBTC TS 1039-2566.

Note: Where a product includes LTE in the 5725–5850 MHz band, Class A registration is required — even if all other bands qualify for SDoC. Where a product operates across multiple bands, only one application is submitted. NBTC issues a single certificate covering all technologies.

Required Documents

  • Technical specification or datasheet including wireless communication details
  • Product photos
  • Test reports (RF, Safety, EMF as applicable) from accredited laboratories
  • ISO/IEC 17025 accreditation certificate and laboratory scope (Class A only)
  • Authorised declaration

No physical product sample submission is required.

Indicative Timeline

SDoCApproximately 1 week from submission
Class AApproximately 5 weeks from submission

Additional time may be required if NBTC requests supplementary documents during review.
