The CCC certification is administered by the Certification and Accreditation Administration of the People's Republic of China (CNCA). 

The objective of the CCC certificate is to provide safe products to its final customers. 

The CCC certification can only be renewed through a follow-up certification. 

The validity of the CCC certification is five years. However, it should be maintained through annual audits. 

You can refer to the First Catalogue of Products Subject to China Compulsory Certification to find whether your product needs CCC certification or not. 

Indeed, the penalty would be imposed on the seller or importer if they try to sell a product in the Chinese market without approval. Moreover, the imported products would be returned to the senders, if not CCC marked. 

Thus, to enter your product in the Chinese market, you must obtain the CCC certificate.

No, the product testing outside China is not authorized.

Indeed, a product could require additional certifications. For instance, telecommunication products and medical products do not require additional certification. However, television might need to acquire a license from the SARFT. 

Thus, you must check the requirement of additional certification, as per the type of your product.
