KC Certification

South Korea is one of the most developed markets in Asia. Accordingly, the certification system has undergone many advances and changes. Before 2009, there were 13 different certifications, some with overlapping content, with 140 different test marks. With the Korean Electrical Appliance & Consumer Goods safety Management Act 2009, the Ministry of Trade, Industry & Energy (MOTIE) standardised the certification market to KC certification.

In the KC system, there are Consumer Products, Children’s Products, Electronics, EMC, KCs (KOSHA, Safety), KEMCO (Energy Efficiency) and MFDS (Food&Drugs). Some areas define product categories, others specific technical properties. It may therefore happen that a product is required to undergo several tests.

The certification process usually consists of application with various forms, product tests (or equal calculated test report tests) and marking. KCs certification may also involve factory inspections.

What is the KC certification for?

Even after the standardisation of the KC certification in 2009, it still has a very high level of complexity due to the different areas and the different certification procedures (also within the areas). An overview of the main differences can be found in this extendable table:

How does the KC certification process work?

The procedures of the new KC certifications are relatively standardised, even though there are still different authorities with different responsibilities. Any given procedure consists minimally of application and proof of product testing to Korean standards, and maximally of application, factory inspection, product testing in Korea, marking and annual (simplified) repetition of this procedure. However, the procedures for a large proportion of products tend to be at the simpler end of this spectrum.

South Korea often advertises the cheapest certification costs in Asia…. For the pure administrative steps this may be true, but please note that testing fees (be it from the product itself or from recognised existing test reports) can be comparatively high even compared to European conditions.

The “Korean Agency for Technology and Standards” (KATS) within the “Ministry of Trade, Industry and Energy” (MOTIE) is responsible for the registration of your KC certification as well as the development of the KC standards. It should be noted that KATS is a member of the International Standardisation Organisation (ISO) and the International Electrotechnical Commission (IEC), so that the Korean standards are largely in line with international standards.

KC certification can be carried out either at the “Korea Testing and Research Institute” (KTR), the “Korea Testing Laboratory” (KTL) or the organisation “Korea Testing Certification” (KTC). The South Korean authorities “National Radio Research Agency” (RRA) and the “Korean Communications Commission” (KCC) are responsible for all EMC-related certifications. The industrial safety certifications KCs and KOSHA, in turn, are carried out either by the “Korea Occupational Safety and Health Agency” (KOSHA), the “Korea Gas Safety Corporation” (KGS), or again at the “Korea Testing Laboratory” (KTL).

Frequent mistakes

There are errors in the application documents

The authorities for KC etc. also have formal requirements that must be observed.

They have recognised test reports, but testing them costs the same as tests themselves

Recognised test reports can shorten the duration of certification, but do not reduce the fees for product tests.

The products do not comply with the standards

Korean KC standards are almost always based on international standards, especially IEC standards. Nevertheless, there are specific differences every now and then.

The products are not marked

Some products do not need to be marked, but most need a KC logo.
