Effective July 1, 2022, CCC applicants can start testing and certification activities based on GB/T 17743-2021, but mandatory dates — the compulsory implementation period — have not yet been defined by the China Quality Certification Center (CQC). This also means that impacts to existing test report and certificates are not available yet and will be defined in the following months.

CCC certification organizations like CQC are expected to issue a notification guideline related to the effectiveness of the new standard and recommended actions for applicants/manufacturers to facilitate the transition plan.
