Electronic products, toys, automotive supplies need 3C, the rest of the free 3C.
3C certification is China's mandatory certification of product quality and safety, this certification is required by the inspection and quarantine requirements, free of 3C certification and "no customs declaration" statement does not exist in correlation.
Because the Entry-Exit Inspection and Quarantine Bureau of part of the electronic products, toys, automotive supplies set the 3C certification requirements, must have 3C certification of the product to enter the Chinese market sales, and for the sample, self-use, and other small quantities of goods, non-market distribution sales, you can apply for exemption from providing 3C certification.
The receipt of the "3C certification exemption approval" can apply for inspection and quarantine declaration procedures, in exchange for entry clearance. With the entry clearance in order to continue for customs declaration procedures, customs declaration will have customs declaration generated, so as to avoid 3C is the same as a customs declaration, free 3C is not the same as free declaration of customs clearance.
Express cargo, then, the value of goods less than 5000 yuan, you can express KJ3 for customs clearance, this is not required to provide 3C certification, do not need to provide the inspection and quarantine certificate requirements, but also no formal customs declaration, belonging to the simple customs clearance.
Based on your case study, this is a multi-batch of goods, may be identified by the Customs and Excise Department as "split single low report", to avoid the declaration of evidence. Customs may require the consolidation of manifest data, not to be less than 5,000 yuan express KJ3 declaration, according to the formal declaration of customs declaration.
