The KC Mark (Korea Certification) is a mandatory safety certification for electrical and electronic products sold in South Korea, managed by KATS (Korean Agency for Technology and Standards). Without the KC Mark, your products will be detained at customs and subject to fines.

In 2026, KC has evolved from simple product testing to a comprehensive system covering product safety, supply chain traceability, and regional compliance. Inspections and penalties have been significantly strengthened.
