KC mandatory certification requires annual factory inspections and product sampling tests. South Korea's safety act requires an initial factory inspection after the application is accepted. Once the certificate is issued, the certification body will conduct an annual follow-up inspection of the factory every two years to check the consistency of the factory's quality control system and whether it can continue to meet the standards of the safety act.
Self-discipline (voluntary) certification does not require factory inspection.
