KC Marking for Radio and Telecommunication Products

The Republic of Korea, usually referred to as South Korea, is one of the world's leading industrial nations. Of course, IEC standards and legal regulations apply there as well, specifying all relevant requirements for the safety of the various products. In order to gain a foothold in the Korean market with your radio and telecom products, you need to prove that all specifications are met. For example, product safety requirements and KC safety certification include a factory audit and a factory inspection. Let our experienced experts help you prepare the necessary CB certificates. You will save costs and, most importantly, a lot of time.

Approval of your Products on the Korean Market

Products with wireless technologies are often found in various product categories such as automotive parts, machinery and equipment in industry, but also in privately used devices. Wireless data transmission enables the remote control of switches and drives, the control of technical processes, and the processing and exchange of information. The used frequency range and the transmitted amount of energy are the most important factors for safety. This applies both to protection against health hazards and to the avoidance of risks from unintentional electromagnetic interference with devices within the range of the radio waves. Certifications are required for almost all radio and telecommunications products offered on the Korean market. They confirm electromagnetic compatibility as well as mechanical and electrical harmlessness according to the requirements of Korean standards.

Our certification service is available for the entire product range. This includes products for vehicle short- and long-range radars, radio frequency identification for reading data storage devices (Radio Frequency Identification, RFID), and for high-frequency areas of industry, science and medicine (Industrial, Scientific and Medical Band, ISM).

Background of KC Mark Certification

KC stands for Korea Certification. In South Korea, your radio and telecommunication products require approval for the market, which you receive after successfully completing certifications by the local authorities. The Korean Ministry of Labor has established a certification system as the basis for approval. It requires a Notified Certification Body to verify that products meet the requirements of national standards for health and safety.

In South Korea, these include the Korea Occupational Safety and Health Agency (KOSHA), the Korea Testing Laboratory (KTL) and the Korea Gas Safety Corporation (KGS). The Korean Communications Commission (KCC) is responsible for the certification of radio and telecommunication products. IB-Lenhardt AG has been working in partnership with the KCC for several years. The approval for the Korean market is indicated on your products by the KC mark, which corresponds to the CE mark in the European Union.

Frequently Asked Questions

All you need to know about KC marking

What does the KC marking mean?

The Korean certification mark on the product indicates that all requirements of the national standards for safety and electromagnetic compatibility have been met and the certification has been successfully completed. This is the prerequisite for certification and access to the market in South Korea.

How does the KC certification process work?

After you have conducted and documented product tests according to Korean standards, you can register your company and apply for certification. You then submit the required documents and a reference product to a Korean Notified Certification Body. Certifications consist of document review, product testing, product evaluation and, in the case of special safety requirements (e.g. explosion protection), surveillance audits at the manufacturer's premises. If the process is successful, the authority issues a certificate.

What documents are required for the application?

In addition to the application form and company registration, the documents you need to apply for certification include documentation showing compliance with Korean standards. This includes design documents, schematics, PCB placements for printed circuit boards, product descriptions or operating manuals in Korean, and existing test reports.

Who assigns the KC marking?

The manufacturer whose products have been certified must mark them with the Korean certification mark. If the product is a component of a technical system (vehicle, machine, plant), the manufacturer of the respective component is obliged to apply for and mark it.

How is the KC marking done?

The marking is engraved or printed on the surface of the products and on the packaging. It consists of the Korean symbol for certifications and the indication of the conformity assessment holder, the product name, the model name, the year of manufacture and the name of the manufacturer and the country of manufacture. This information is provided in the Korean language. In addition, an identification number must be provided according to a specified key.
