Label Requirements for RF Certification in Thailand: Two Mandatory Labels You Need to Know

The first step in marketing your product in Thailand is to obtain Radio Frequency (RF) certification. The final step before the product can be legally marketed is to apply the required labeling.

Labeling requirements for RF certification in Thailand are mandatory. However, there are three product classes with three different labeling requirements. Failing to comply with or making mistakes in this process will delay the import and distribution of your products.

In this article, we’ll cover everything you need to know about labeling requirements for RF certification in Thailand. You can also watch the full video to learn the requirements in detail.

Label Requirements for RF Certification in Thailand

The National Broadcasting and Telecommunications Commission (NBTC) has three requirements regarding labeling. These include what must be included on the label, where it must be placed, and what warnings must accompany it.

As we know, there are three certification classes in Thailand: Class A, Class B, and SDoC. Each of these classes has its own specific requirements based on established regulations.

Class A label

Let’s start with the Class A label. The label for this type of certification requires three components: the NBTC logo, the class designation, and the NTC ID.

• NBTC Logo: Indicates that the product has been officially verified by the NBTC.
• Class type: Labelled “Class A”
• NTC ID: A unique identifier consisting of a six-digit registration number, a two-digit registration year, and a four-digit supplier code.

This label must be affixed directly to the product’s surface in a clear and permanent manner. You may also affix the label to the packaging or user manual if the product is too small to accommodate the label.

Class B Label

The Class B label has the same component structure as Class A: the NBTC logo, class type, and NTC ID. However, only the format of the NTC ID is slightly different.

The unique identifier on Class B consists of a six-digit certification number (not a registration number), a two-digit registration year, and a four-digit supplier code. The placement rules are also the same: directly on the product, clearly visible, and permanently affixed.

SDoC Label

The Supplier’s Declaration of Conformity (SDoC) has a different format from Class A and Class B. This type of certification does not need to include a logo, class type, or NTC ID.

The label for the SDoC consists solely of a written statement of conformity in Thai or English. This statement explains that the product complies with applicable standards or technical requirements

• In Thai: “เครื่องโทรคมนาคมและอุปกรณ์นี้มีความสอดคล้องตามมาตรฐานหรือข้อกำหนดทางเทคนิค ของ กสทช.”
• In English: “This telecommunications equipment complies with NBTC’s standards or technical requirements.”

The statement does not need to be affixed to the product. It is sufficient to include the statement in the user manual or other supporting documents provided with the product at the time of sale.

The Notice Label

This is what sets Thailand apart from most other countries. Not only are there specific labels for these three types of products, but the NBTC also requires each product to have its own warning label.

There are two formats for warning labels: Class A and Class B, which require a license, and SDoC, which is exempt from licensing. Both warning labels must measure 5 centimeters by 5 centimeters.

The labels are affixed to the user manual, the packaging, or included as an insert inside the packaging. It’s important to remember that these notice labels are not optional—a detail that is often overlooked by most manufacturers.

Notice labels are a separate requirement distinct from the main label. They are supplementary labels. Therefore, there are two mandatory labels for NBTC certification: the specific label for each type of certification and the notice label.

Labels and Recertification

In addition to labeling requirements, you should understand the implications if recertification is required. As explained in a previous article, there is no validity period for RF certification in Thailand. The certificate will only become invalid if there are modifications to the RF design. If this occurs, recertification is required.

Each certificate has its own NTC ID. Recertification means the NTC ID has changed. This is where it affects the label on your product.

When a product must be recertified due to modifications, the label on the product must also be updated. Units produced after recertification must be affixed with a new label bearing the new NTC ID. The original label remains valid for units already on the market.

That’s a brief overview of the labeling requirements for RF certification in Thailand. To see the visual format of each type of label, you can watch the video for a clearer explanation.
