KC certification, or Korean certification, is a product certification to ensure that products meet Korean safety standards (named K standards). KC certification (KC Mark Korea certification) focuses on preventing and reducing risks in terms of safety, health or environmental impact. Before 2009, different government agencies had 13 different certification systems, some even partially overlapping. In 2009, the Korean government decided to introduce KC mark certification and replace the previous 140 different test marks. The KC mark and the corresponding KC certificate are similar to the European CE mark and are applicable to 730 different products, such as auto parts, machines and many electronic products. This test mark confirms that the product complies with relevant Korean safety standards.

At present, three major institutions are recognized as certification bodies, and are approved to conduct product testing, factory audit and issue certificates. These institutions are Korea Testing and Research Institute (KTR), Korea Testing Laboratory (KTL) and Korea Testing Certification (KTC)

KC EMC certification confirms that electronic equipment, products and radio technology meet the requirements of electromagnetic compatibility. This certification is managed by the National Radio Research Agency (RRA). Since 2011, KC EMC certification has become a part of KC certification system. On this basis, the KC mark, as a unified mark, is also used for the mark under KC EMC.

Most of the technical equipment in the information, communication and telecommunications industries that will be sold in Korea need to obtain KC EMC certification. This certification confirms that the product conforms to electromagnetic compatibility and is harmless to consumers.

Products equipped with wireless and radio technologies need KC EMC certification to enter the Korean market.

These products usually use WIFI, Bluetooth, RFID and other wireless communication technologies.
