KC Certification for Electronic Products

The KC marking confirms that a product complies with South Korea’s applicable regulatory requirements and has successfully completed the required conformity assessment procedures.
For radio and telecommunication equipment, this primarily relates to approval under the Radio Waves Act by the Radio Research Agency (RRA).

The process depends on the product category but typically includes local testing in Korea, appointment of a Korean applicant, and electronic submission via the RRA’s eKCC system.
For most radio-enabled products, RRA approval is mandatory before import or sale. Further details are explained in our Knowledge Base: RRA Certification Process.

Applications require technical documentation, official Korean test reports, and Korean-language labeling and user documentation. Foreign FCC or CE reports are generally not accepted as substitutes. A complete document overview is available in the Knowledge Base: Required Documents for RRA Approval.

The KC marking must be applied by the certificate holder registered with the RRA.
For imported products, this is usually the local representative or importer acting on behalf of the manufacturer.

The KC mark and certification number must be permanently affixed to the product and be clearly visible.
In specific cases, alternative labeling methods may be permitted. Practical examples and labeling rules are covered in the Knowledge Base: KC Marking & Labeling Requirements.
