Afterwards the application documents for the respective products have to be handed in at the CRCC. For the third step, companies shall send product sample to the CRCC for receiving the test reports with the test results which are issued only in Chinese. 
If all product tests are completed successfully, Chinese inspectors will visit the manufacturing site for a 2-day audit. After the factory audit, the CRCC will issue a Certificate of Approval.
