- Can declare in advance and two-step declaration be used together? Yes, and the Customs hopes that import and export enterprises can further improve the time limit for customs clearance by combining declare in advance with two-step declaration.

- The key premise of the two-step declaration is the same as that of declare in advance, that is, manifest data has been transmitted to China's customs in a complete, accurate and timely manner.

On October 30, Xinhai responded to Shanghai Customs' pilot work of "two-step declaration" and completed the "summary declaration" of the two- step declaration. On October 31, when the ship arrived, the receipt of the customs approval for departure was also reached simultaneously, and the pilot was a complete success.
