First of all, we should make clear the classification details of commodities, and decide whether we need import and export customs clearance forms for commodity inspection according to the classification of commodity codes. If there is, it depends on what kind of goods the commodity belongs to in the requirements of the commodity inspection bureau. The regulatory requirements for each commodity will be different, such as textiles, mechanical and electrical products, toys, wood products, food and so on. And the scope involved is too wide. Only the specific goods can be answered specifically, and the customs declaration formalities can be handled after commodity inspection. On the issue of customs declaration, it depends on the classification of goods. There will be a temporary import and export date, and some need to be approved by the department.
