Table 1. Unified customs declaration solution in mainland China

The customs system checks the order information, payment information, logistics information, and import list by following the steps below:

Match the four documents with the same value of the orderNo parameters.
Ensure that all the enterprises involved in the declaration are registered by checking the registration information in each document. For more information, see Table 2.
Logically compare the order information, payment information, and logistics information with the import list. For more information, see Table 3.

The table below lists the key information contained in the four documents.

Table 2. Key information in the four documents

The table below lists the Customs' check logic among the four documents.

Document	Order information	Payment information	Logistics information	Import list
Order information	The value of goodsValue equals the sum price of goods contained in orderList, with an error within 1 yuan allowed. The following formula is satisfied: acturalPaid = goodsValue + freight + taxTotal - discount.	The buyer information is consistent with the payer information. The values of acturalPaid are the same, with an error within 1 yuan allowed. The e-commerce platform registration information is consistent.	The consignee information is consistent.	The buyer information is consistent. The value of freight in the order information is the sum of freight and insuredFee in the import list. The goods information is consistent.
Payment information	N/A	N/A	N/A	N/A
Logistics information	N/A	N/A	N/A	The value of packNo is the same.
Import list	N/A	N/A	N/A	The sum weight of goods contained in inventoryList is no more than the value of grossWeight.
