KC (Korea Certification) is a mandatory product certification in Korea to ensure the safety of its citizens. It requires that safety management objects, including electronic and electrical products or household goods, meet relevant Korean safety conditions before entering the Korean market. The KC certification uses a unified KC mark (2009), which was formed by merging 13 statutory mandatory marks in Korea. The main requirements for electronic and electrical products to enter the Korean market are in three aspects: safety, electromagnetic compatibility (EMC), and radio frequency (RF) certification. After obtaining the certificate, the KC certification mark and the corresponding certification number need to be printed on the product nameplate. The radio frequency part can reference the certificate of the integrity module.
