We support RRA conformity assessment and KC marking for radio and electronic products entering South Korea. Plan your testing, documentation and next steps with our team.
Market Access for South Korea
RRA Assessment and KC Marking
Listed radio, telecommunications and EMC-relevant products require conformity assessment under South Korea’s Radio Waves Act. The National Radio Research Agency (RRA) administers the procedures for the applicable radio, telecommunications, EMC and RF exposure requirements. Separate KC product-safety requirements may also apply, depending on your product.
We help you identify the assessment route and prepare for market entry.
Plan Your Route to the Korean Market
The applicable route depends on the equipment classification: certification, registration or self-verification. Interim certification may be granted under specific legal conditions, for example where applicable technical criteria do not yet exist.
Plan test evidence that meets Korean requirements. RRA-recognized laboratories under a Mutual Recognition Agreement (MRA) can test abroad within their recognized scope. Applicants without an address or business office in Korea must appoint a Korean agent in writing.
Explore the RRA conformity assessment requirements in our Knowledge Base.
KC Marking and Assessment Records
Complete the applicable assessment and KC marking before market entry. Certification and registration produce different documents and numbers; self-verification requires a published declaration and a management number. RRA public records support verification of the assessment.
Applications are submitted through the e-civil-service portal of the Ministry of Science and ICT (MSIT) at emsit.go.kr. The selected route determines what you submit, publish and retain. See our guide to KC marking requirements and public records.

Frequently Asked Questions
Practical Questions About KC Assessment and Marking
- What does the KC marking mean?
-
KC marking indicates that a product meets the applicable Korean requirements and has completed the required conformity assessment. For listed radio, telecommunications and EMC-relevant equipment, the National Radio Research Agency (RRA) administers the procedures under the Radio Waves Act. Separate product-safety requirements may also apply.
- How does the KC certification process work?
-
Start with the equipment classification to determine whether certification, registration or self-verification applies. Interim certification may be granted under specific legal conditions. Plan accepted test evidence, prepare the required application or declaration and complete the KC marking. An applicant without an address or business office in Korea must appoint a Korean agent in writing.
See the RRA conformity assessment process for the route-specific steps.
- What documents are required?
-
The documents depend on the assessment route. Certification requires a Korean user manual; interim certification also requires a Korean technical description and manual. Registration and self-verification have their own submission, publication and document-retention duties.
Reports from RRA-recognized MRA laboratories can be used within their recognized scope when they address Korean requirements. An FCC or CE approval alone does not replace Korean conformity assessment. See the route-specific documents and evidence.
- Who is responsible for applying the KC marking?
-
The certificate or registration holder, or the party making the self-verification declaration, is responsible for the required marking. A Korean agent handles specified tasks on the applicant’s behalf; appointment alone does not make it the holder. The holder, agent and importer may be different parties.
- How must the KC marking be applied?
-
Apply the KC mark and the identification details required for the selected route to the equipment or its packaging. For self-verification, provide the additional required information and the RRA declaration address in the manual or declaration. Certification, registration and self-verification use different identification numbers. Reduced marking and electronic display or QR-code methods are available under defined conditions.
