## Customs check logic

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

1.  Match the four documents with the same value of the _orderNo_ parameters.
2.  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.
3.  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.

| **Item/Document** | **Order information** | **Payment information** | **Logistics information** | **Import list** |
| --- | --- | --- | --- | --- |
| Order No. | - _orderNo_ | - _orderNo_ | - _orderNo_ | - _orderNo_ |
| Payment No. | - _payTransactionId_ | - _payTransactionId_ | N/A | N/A |
| Logistics No. | N/A | N/A | - _logisticsNo_ | - _logisticsNo_ |
| E-commerce platform registration information | - _ebpCode_ - _ebpName_ | - _ebpCode_ - _ebpName_ | N/A | - _ebpCode_ - _ebpName_ |
| E-commerce enterprise registration information | - _ebpCode_ - _ebpName_ | N/A | N/A | - _ebpCode_ - _ebpName_ |
| Payment enterprise registration information | - _payCode_ - _payName_ | - _payCode_ - _payName_ | N/A | N/A |
| Logistics enterprise registration information | N/A | N/A | - _logisticsCode_ - _logisticsName_ | - _logisticsCode_ - _logisticsName_ |
| Consignee information | - _consignee_ - _consigneeTelephone_ - _consigneeAddress_ | N/A | - _consignee_ - _consigneeTelephone_ - _consigneeAddress_ | N/A |
| Buyer or payer information | - _buyerName_ - _buyerTelephone_ - _buyerIdType_ - _buyerIdNumber_ | - _payerName_ - _payerIdType_ - _payerIdNumber_ | N/A | - _buyerName_ - _buyerTelephone_ - _buyerIdType __buyerIdNumber_ |
| Goods fee information | - _goodsValue_ - _freight_ - _taxTotal_ - _discount_ - _acturalPaid_ | - _amountPaid_ | - _freight_ - _insuredFee_ | - _freight_ - _insuredFee_ |
| Goods information | - _orderList_ | N/A | - _packNo_ | - _packNo_ - _inventoryList_ - _grossWeight_ |

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** | 1. The value of _goodsValue_ equals the sum price of goods contained in _orderList_, with an error within 1 yuan allowed. 2. The following formula is satisfied: _acturalPaid_ \= _goodsValue_ \+ _freight_ \+ _taxTotal_ \- _discount_. | 1. The buyer information is consistent with the payer information. 2. The values of _acturalPaid_ are the same, with an error within 1 yuan allowed. 3. The e-commerce platform registration information is consistent. | The consignee information is consistent. | 1. The buyer information is consistent. 2. The value of _freight_ in the order information is the sum of _freight and insuredFee_ in the import list. 3. 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_. |
