ROK Conformity Assessment System: Conformity Marks Used in Korea

Conformity Assessment System

In order to demonstrate compliance with certain standards or other requirements, manufacturers often place marks of conformity on their products, which are usually granted by certification or accreditation bodies. In Korea, there are a couple different marks that are used in the market.

KS Mark

As already mentioned, the KS mark indicates conformity with applicable Korean Industrial Standards (KS), and is granted by the certification body, the Korean Standards Association (KSA). In most cases, obtaining the KS mark is a voluntary measure designed to enable manufacturers to enhance their competitiveness and empower consumers by providing information about the quality of products.

KC Mark

Beginning July 1, 2009, the Korean Agency for Technology and Standards (KATS) implemented a new certification mark, the Korea Certification (KC) Mark. The new KC mark is designed to integrate thirteen certification marks previously required by mandatory certification systems from the Ministry of Knowledge and Economy (MKE) and the Ministry of Labor (MOL). By November 1, 2011, mandatory certifications required by all Korean ministries will use the KC mark.
