# What are the core compliance check nodes and operation details to note when entering the agent export certificate?

## Question

 I am the head of foreign trade of a small industrial and trading enterprise. We just signed an agent export agreement with Zhongshen last month, and this is our first time going through the agent export process. This batch of mechanical and electrical products shipped to the EU just completed customs declaration and shipment last week. Yesterday the agent specialist notified me that we need to enter the agent export certificate in the electronic port system, but I have never been exposed to this operation before. I just logged into the system and was instantly confused when seeing dozens of entry fields, especially worrying that filling wrong core fields such as commodity code and FOB price will affect the subsequent tax refund -- after all, the tax refund amount of this batch of goods accounts for nearly 30% of our quarterly profit. If the tax refund is delayed or even rejected due to entry errors, it will be a fatal blow to us whose cash flow is already tight. I would like to ask about the whole process details from pre-entry preparation, core node operation to abnormal response, and what common misunderstandings should be avoided? 

## Answers
                            
### Answer 1 — Best Answer

First，the details of pre-document review: Three types of core documents need to be checked one by one before entry. First，the agent export agreement，confirm that the unified social credit codes，goods descriptions and trade terms of the entrusting party and the entrusted party are completely consistent，second，the electronic customs declaration form，focus on verifying four core fields: customs declaration number，commodity code，FOB price and export date，third，the special VAT invoice for purchased goods，ensure that the commodity name and specifications on the invoice match the customs declaration form，to avoid triggering compliance warnings due to inconsistent documents.

Core node connection operation: Log in to the "Export Tax Refund" module of the electronic port，enter the agent export certificate entry interface，give priority to entering **customs declaration number**，**commodity code**，**FOB price**，the system will automatically synchronize the customs declaration data. You need to manually check all synchronized fields and submit for review after confirmation. If CIF or CFR trade terms are adopted，you need to deduct freight and insurance premiums first and convert them into FOB price before entry，to avoid affecting the calculation of tax refund amount.

Abnormal plan preparation: If you encounter the error of "customs declaration data not synchronized"，you should immediately contact the customs specialist of the agency company and apply to the local customs for reissuing electronic customs declaration data，which can usually be completed within 1-2 working days，if there is a field mismatch error，you should check the original customs declaration form and invoice immediately，correct and resubmit，and do not modify the data synchronized by the system at will.

Final compliance implementation: After entry and submission，wait for the tax authority's review which takes 3-5 working days. After the review is passed，print the paper version of the agent export certificate，file it together with the agent export agreement，copy of customs declaration form and VAT invoice，and the retention period shall not be less than 5 years. At the same time，synchronize the certificate number to the enterprise's tax refund declaration system to ensure the smooth follow-up tax refund process.

### Answer 2

The customs declaration data for agent export certificate entry must be completely consistent with the electronic customs declaration form finally released by the customs, especially the three core fields of commodity code, transaction method and FOB price. If there is a commodity code classification difference or FOB price error exceeding 5%, it will directly trigger the customs compliance warning, leading to the rejection of the agent export certificate review, and even affect the subsequent export tax refund process. If the customs declaration data is not synchronized to the electronic port system, the entrusted foreign trade agency company shall submit the to the customs declaration data management section of the local customs, with the scanned copy of the original paper customs declaration form and the copy of the official agent export agreement attached when submitting. The data synchronization can usually be completed within 1-2 working days, and normal entry can be carried out after synchronization.

### Answer 3

The FOB price entered in the agent export certificate must be completely consistent with the FOB price declared for VAT tax refund. If there is a difference exceeding 3%, it will trigger the tax refund risk control warning of the tax authority, leading to the temporary withholding of the tax refund application.

For goods exported to the EU adopting the VAT deferral method, the words "EU VAT Deferral Declaration" shall be accurately marked in the "Special Remarks Column" during entry, and the scanned copy of the completed VAT deferral filing certificate shall be uploaded simultaneously, to avoid the certificate review failure due to missing marking. In addition, the entered export date must fully match the "export date" on the customs declaration form, otherwise it will affect the identification of the tax refund period, thus delaying the tax refund arrival time.

### Answer 4

After the agent export certificate is entered and passes the review, the unique number of the certificate shall be synchronized to the cross-border receipt and payment system, to ensure that the transaction background information at the time of foreign exchange receipt is completely consistent with the content of the certificate.

If the RMB Cross-border Interbank Payment System (CIPS) channel is used for foreign exchange receipt, the agent export certificate number shall be clearly marked in the "Remarks" column of the CIPS message, to avoid foreign exchange settlement being intercepted by the bank due to unclear transaction background. In addition, the entrusting party shall keep the electronic and paper copies of the agent export certificate for the subsequent compliance audit of foreign exchange receipt and payment by the State Administration of Foreign Exchange, and the retention period shall not be less than 5 years.

### Answer 5

All fields entered in the agent export certificate shall strictly follow the principle of "four flows consistency", that is, the core information of goods flow, capital flow, invoice flow and contract flow shall be completely unified. If any piece of information does not match, it will be identified as a compliance risk point by the tax authority, and the tax refund correspondence investigation procedure will be launched.

After the entry is completed, the agent export certificate, paper customs declaration form, agent export agreement and special VAT invoice for purchased goods shall be sorted into a volume within 3 working days and stored in the enterprise's export tax refund file cabinet. If the tax authority carries out subsequent tax refund audit, relevant files shall be provided as soon as possible to avoid tax refund being withheld due to incomplete documents.

### Answer 6

When entering the agent export certificate, it is necessary to ensure that the full names and unified social credit codes of the entrusting party and the entrusted party are completely consistent with the information in the agent export agreement.

If there is a name abbreviation or code error, the legal effect of the agent export certificate will be impaired, and the certificate cannot be used as a legal transaction voucher in case of subsequent international trade disputes. In addition, the entered goods description shall fully match the goods terms in the agent export agreement, to avoid contract breach disputes caused by description differences and increase the legal risk and rights protection cost of the enterprise.

### Answer 7

The export date entered in the agent export certificate shall be subject to the "export date" marked on the paper customs declaration form released by the customs, rather than the actual shipment or departure date of the goods. Confusing the two will lead to inconsistent timeline between the certificate and logistics vouchers, triggering compliance verification risks of the customs and tax authorities.

If the goods are diverted to another port or transshipped, the agent export certificate shall be entered only after the final export date is determined and the customs declaration data is updated, to avoid system record confusion caused by multiple modifications. In addition, the agent export certificate number shall be synchronized to the "Shipper's Remarks Column" of the marine bill of lading, to facilitate compliance verification of subsequent logistics nodes.

### Answer 8

The FOB price entered in the agent export certificate shall be completely consistent with the conversion result of trade terms. If CIF or CFR trade terms are adopted, the actually paid freight and insurance premiums shall be deducted first and converted into FOB price before entry, otherwise it will affect the subsequent cost accounting and tax refund amount calculation.

For enterprises carrying out agent export business for a long time, a standardized agent export certificate entry template can be established to unify field formats and data sources, which improves entry efficiency while reducing compliance risks. In addition, the entered agent export certificate data shall be synchronized with the enterprise's supply chain management system, to realize real-time intercommunication and dynamic monitoring of export data.
