Initial Factory Audit:​ Conducted at the time of initial certification to ensure the factory has the capability to produce compliant products.

Annual Surveillance Audit:​ After the certification is granted, the certification body will conduct a surveillance audit once a year to ensure ongoing compliance with requirements.

2.4 Certificate Issuance:

After passing the testing and factory audit, the certification body will issue the KC certification certificate. The company may then affix the KC mark on its products, indicating compliance with Korea‘s safety requirements and allowing the products to be sold in the Korean market.

2.5 Questions

1. Does KC certification require a factory audit?

KC certification requires a factory audit in certain cases, depending on the risk level of the product and the type of certification:

Mandatory Safety Certification (KC Safety Certification):

Factory audit required:​ For high-risk electrical appliances such as household appliances, information technology equipment, etc., a factory audit is mandatory. This includes an initial factory audit and subsequent annual surveillance audits.

Audit content:​ Quality management system, production process control, management of raw materials and components, product consistency, etc.

2. If the factory is located in China, how is the factory audit for KC certification conducted?

When the manufacturing factory is located in China and applying for KC certification in South Korea, the factory audit remains a necessary step. Below are the specific procedures and considerations for factory audits when the factory is in China:

Arrangement of the Audit by the Certification Body

Korean certification bodies dispatch auditors:​ Korean certification bodies such as KTL, KTC, or KTR will send trained and authorized auditors to the factory in China to conduct on-site inspections.

Entrustment to local partner organizations:​ Some Korean certification bodies may entrust their partner organizations in China or qualified third-party inspection agencies to conduct the factory audit on their behalf.

3. Self-Regulatory Safety Confirmation:

Factory audit may not be required:​ For medium-risk products, companies are required to self-confirm that their products comply with safety standards, and submit test reports along with relevant documentation.

Spot-check mechanism:​ Relevant Korean authorities may conduct irregular spot checks, but regular factory audits are not required.

4. Supplier‘s Declaration of Conformity:

No factory audit required:​ For low-risk products, companies may self-declare that their products comply with relevant standards, without the need for a factory audit.

5. Summary:

Products subject to mandatory certification:​ A factory audit is required.

Voluntary or low-risk products:​ A factory audit is generally not required, but it is necessary to ensure that the products comply with relevant standards and to retain the required technical documents for inspection purposes.

III. Key Focus of KC Certification: Compliance with Relevant Standards
