KC certification is mandatory for electrical/electronic products and many other consumer goods. Here's a practical rundown of which category you fall into, accredited test labs and timelines, and the Korean-agent requirement.
What KC certification is
The KC (Korea Certification) mark is a statutory mandatory certification required to sell products in Korea. It's grounded in several laws, including the Electrical Appliances and Consumer Products Safety Control Act, the Radio Waves Act, and the Special Act on the Safety Control of Children's Products.
Selling a covered item without the KC mark can mean customs rejection, a sales ban, and fines. Platforms such as Coupang and Naver also require a copy of the KC certificate.
Covered categories
| Category | Governing law | Note |
|---|---|---|
| Electrical/electronic products (chargers, appliances, etc.) | Electrical Appliances Safety Control Act | Mandatory certification in most cases |
| Wireless devices (Bluetooth, Wi-Fi) | Radio Waves Act | Separate conformity certification |
| Children's products (toys, stationery) | Special Act on Children's Product Safety | Supplier conformity declaration or safety certification |
| Household chemical products (cleaners, fragrances) | Household Chemical Products Safety Control Act | Approval or notification |
| Apparel/textiles (some items) | Quality Management and Safety Control of Industrial Products Act | Check whether it's a safety-confirmation item |
The certification process
Cost & things to watch for
Test costs run roughly KRW 2M–15M, depending on the item and the number of test items. There's also an ongoing certificate-maintenance cost (annual renewal, etc.).
A common mistake: if the certified model's specs differ from what's actually sold (a component swap, for example), the certification becomes invalid and retesting is required. Always check with the certifying body before changing a model.
