Thailand NBTC Type Approval: Step-by-Step Guide for Wireless & Telecom Devices

Thailand is a growing market for wireless, telecom, IoT, and connected devices. Before manufacturers import, distribute, or sell these products in Thailand, they need to check which NBTC requirements apply to their products.

The National Broadcasting and Telecommunications Commission (NBTC) regulates telecommunications, broadcasting, and radio frequency use in Thailand. Its rules help ensure that wireless devices meet technical requirements and do not cause harmful interference.

For manufacturers, the process starts with identifying the right regulatory route and preparing the required documents and test reports.

Step 1: Check If NBTC Requirements Apply

First, check whether the product is covered by NBTC requirements.

This can include:

• Mobile phones and tablets

• Wi-Fi and Bluetooth devices

• IoT and smart home products

• RF modules

• Short-range wireless devices

• Cellular equipment

• Other radio and telecom equipment

The product’s technology, frequency, power level, and intended use should be checked before choosing the approval route.

Step 2: Choose the Right NBTC Route

Thailand has different regulatory routes depending on the type of product.

Supplier’s Declaration of Conformity (SDoC)

SDoC is used for certain low-power and short-range wireless devices that operate within specified limits.

Examples include some:

• Wi-Fi devices

• Bluetooth products

• Short-range wireless equipment

The process is mainly based on documentation, but the product must still meet the applicable NBTC requirements.

Class A Certification

Class A applies to certain radio equipment that meets specific technical and frequency requirements.

Depending on the product, manufacturers may need:

• Product specifications

• Radio test reports

• Safety test reports

• EMF/SAR reports

• ISO/IEC 17025 accredited lab reports or ISO 9001 factory certification (where applicable)

Certain RFID, UWB, and radar products may fall under this route, depending on their technical characteristics.

Class B Certification

Class B generally covers more complex radio and telecom equipment, including certain products used with public communication networks.

It can include technologies such as:

• GSM

• WCDMA

• LTE

• 5G NR

Additional RF, safety, EMF/SAR, and other applicable test reports may be required.

Choosing the correct route from the beginning can help avoid unnecessary questions and delays.

Step 3: Check the Technical Requirements

After choosing the route, manufacturers should check the technical requirements that apply to the product.

These may include:

• RF performance

• EMC

• Electrical safety

• EMF

• SAR

• Frequency bands

• Output power

• Wireless technology

Requirements can vary from one product to another. A Bluetooth accessory, for example, will not have the same requirements as a 5G smartphone.

Step 4: Prepare the Documents

The required documents depend on the product and regulatory route.

Common documents may include:

• Product specifications and datasheets

• User manual

• Declaration of Conformity

• RF test reports

• EMC test reports

• Safety reports

• EMF/SAR reports, where applicable

• GSMA TAC information for cellular devices

• Product photos and labels

• Other supporting documents

Make sure the information is consistent across all documents. Model numbers, product names, manufacturer details, and technical specifications should match.

Step 5: Check Existing Test Reports

Manufacturers may be able to use existing international test reports to support an NBTC application if they meet the applicable requirements.

For example, CE or FCC reports may support the application when they cover the relevant Thai requirements.

However, CE or FCC certification does not automatically replace NBTC requirements.

Existing reports should be checked to make sure they cover the required frequencies, technologies, standards, and test conditions.

Step 6: Appoint a Local Representative

A local representative in Thailand is required for the NBTC certification process.

The local representative acts as the main communication channel between the applicant and NBTC and helps with:

• Application coordination

• Communication with NBTC

• Document submission

• Responding to regulatory queries

• Application follow-up

Manufacturers should arrange the local representative early to help keep the certification process on track.

Step 7: Submit the Application

Once the product route, documents, test reports, and any local requirements are ready, the application can be submitted through the relevant NBTC process.

Before submission, check that:

• Model numbers are correct

• Manufacturer details are accurate

• Technical information matches

• Test reports are complete

• Frequency information is correct

• Required declarations are included

• Supporting documents are complete

  
  

Step 8: NBTC Reviews the Application

NBTC or the relevant certification channel reviews the application and documents.

If something is missing or unclear, the applicant may need to provide additional information.

Good preparation can help reduce questions and avoid unnecessary delays.

Step 9: Receive the Applicable Approval

Once the applicable requirements are met, the product can receive the relevant NBTC type approval or certification.

The manufacturer can then proceed with the applicable import, distribution, or sales activities, subject to other requirements that may apply.

Step 10: Maintain Compliance

Getting approval is not always the end of the process.

Manufacturers should review major product changes, such as changes to:

• Hardware

• RF components

• Operating frequencies

• Wireless technology

• Internal design

• Software affecting wireless functions

Depending on the change, an updated assessment or new certification may be required.

NBTC Type Approval Checklist

Before starting, manufacturers should check:

• Does the product fall under NBTC requirements?

• Which regulatory route applies?

• What frequency bands does it use?

• What testing is required?

• Can existing test reports be used?

• Are RF, EMC, safety, and SAR requirements covered?

• Is GSMA TAC information required?

• Is local representation required?

• Do all documents show the same model information?

• Could product changes affect the approval?
