Korea KS Certification
Korea KS Certification

The KS certification is a voluntary certification system that conducts strict audit on companies that can continuously and stably produce products above the Korean Industrial Standards (KS) level. The KS certification mark can be affixed when products passed the strict audit. The system promotes the simplification and transparency of transactions and processes through the promotion of standardized products and services, which not only protects consumer rights and public safety, but also eliminates the need for quality confirmation and other procedures when countries, enterprises and public organizations purchase products, saving money and time.

Certification mark

According to the provisions of the Korean Industrial Standardization Law, KS certification is divided into product certification and service certification. All products or services selected as KS certification objects need to go through factory inspection, product inspection, or service inspection according to the corresponding KS standards. After passing the inspections, a KS certificate can be issued. CIRS currently provides KS product certification, the following content is only for reference during product certification.

The KS mark certification can only be obtained for product varieties that are designated by the Korea Institute of Technical Standards and are deemed necessary for the popularization and promotion of national standards. As of 2008, there are more than 800 kinds of products designated with the KS mark, and more than 6,000 factories have obtained more than 12,000 KS certifications. The factory audit standard adopted in the KS mark certification process is called "KS certification audit standard". The audit standard specifies the specific requirements of each item in detail. Therefore, it is recommended that enterprises purchase the audit standard, fully understand the requirements of the audit standard, and prepare according to its content, which can effectively promote the certification business.
