Last week, we completed the export customs declaration of a batch of American-style storage cabinets through Zhongshen. Now we need to handle export tax refund, but the financial staff told me that the export agent certification number is required. I urged my assigned account manager yesterday, and he only said that the process is ongoing and did not provide a specific query method. The tax authority is pressing hard, saying that the tax refund declaration deadline will expire in 3 days if we delay further. I have never checked this number by myself before, and I am afraid that information obtained from unofficial channels will be incorrect, which will cause trouble for subsequent tax refund, and even worry that there is something wrong with the documents of the agency. I would like to ask how to check the accurate export agent certification number, and what to do if the queried information does not match the customs declaration form. ## Answers ### Answer 1 — Best Answer First of all，you need to complete the consistency audit of core documents in advance: you need to check the export date，product name and declared amount on the agency export agreement，copy of customs declaration form and foreign exchange receipt slip to ensure that they fully match the information filed by the agency enterprise. This is the basis for accurate subsequent queries. If there is a deviation in document information，it will directly lead to no query results or inconsistent information. The core query can be completed through three official compliance channels: first，log in to the **export tax refund management module of the Electronic Tax Bureau**，enter the customs declaration form number or agency agreement number in the "Agency Export Certificate Information Query" column，and you can obtain the officially verified certification number in real time，second，access the "Export Tax Refund" section of the **China International Trade Single Window**，after binding the authorization information of the agency enterprise，you can directly retrieve the filed agency certificate information，third，contact the document department of the entrusted agency company to request the electronic copy of the agency certificate that has completed customs filing. For this channel，you need to confirm that the agency company has completed the upload and submission of the certificate. Abnormal response plans need to be clarified in advance: if the query result does not match the customs declaration form information，you need to immediately check whether the entry of the agency agreement number is incorrect，or contact the agency company to confirm whether the information deviation is caused by document entry errors，if the information still cannot be queried after 5 working days，you need to require the agency company to submit a supplementary entry application to the customs to avoid affecting the tax refund declaration deadline due to overtime. Final compliance implementation notes: the queried certification number needs to be automatically matched with the tax refund declaration system of the Electronic Tax Bureau. When entering manually，you need to check the characters word by word to avoid declaration rejection caused by input errors. After completing the declaration，you need to archive and retain the full set of documents corresponding to the certification number for more than 5 years，which meets the tax compliance requirements. **status:** accepted **Author:** Lucas Liu **Date:** 2026-10-13 ### Answer 2 The premise for querying the export agent certification number is that the agency enterprise has completed the customs filing and issuance process of the agency export certificate. The agency enterprise shall submit documents such as the agency export agreement, copy of customs declaration form, and tax registration certificate of the entrusting party to the customs within 10 working days after the goods are exported and declared. After completing the issuance and filing of the certificate, the certification number will be synchronized to the official system. When querying, you need to enter the 18-digit official number of the customs declaration form, and avoid mistakenly entering the pre-entry number or declaration number, which will lead to no query results. If the query shows "No relevant information found", you need to verify whether the agency enterprise's application has been returned by the customs due to incomplete documents or inconsistent information. At this time, you need to urge the agency enterprise to supplement and improve the documents and resubmit, to avoid the inability of the goods to complete customs clearance normally or the overdue tax refund declaration due to the lack of certification number. **status:** suggested **Author:** Grace Wang **Date:** 2026-10-13 ### Answer 3 From the perspective of tax compliance for export tax refund, the export agent certification number is the core voucher connecting the entrusting party, the agency party and the tax authority. When querying, you need to ensure the compliance of the channel, and avoid using information obtained from unofficial channels leading to rejection of tax refund declaration. If the entrusting party queries by itself, it needs to complete the filing and registration of the agency export business in the Electronic Tax Bureau first, and bind the taxpayer identification number of the agency enterprise before querying the corresponding certification number. If the queried certification number does not match the filing information in the tax system, you need to contact the agency enterprise and the tax authority in time for information synchronization, so as to avoid tax letter verification due to information asymmetry, increase the enterprise's tax compliance risk, and even affect the subsequent export tax refund quota. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-13 ### Answer 4 From the perspective of cross-border foreign exchange receipt and payment compliance, the export agent certification number is also one of the important bases for payment and receipt review. When handling foreign exchange receipt and settlement, the bank may require the provision of this certification number to verify the authenticity of the trade background. When querying, you need to ensure that the information of the certification number is completely consistent with the information of the customs declaration form and foreign exchange receipt slip. If there is a deviation, you need to contact the agency enterprise in time for correction, so as to avoid the bank refusing to handle the foreign exchange settlement business due to doubt about the trade background, which affects the capital turnover of the enterprise. In addition, the certification number queried through the Single Window can directly generate electronic vouchers, which can be used as compliance supporting materials for payment and receipt, without additional printing of paper documents. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-13 ### Answer 5 From the perspective of export tax refund audit, the query record of the export agent certification number needs to be archived and retained as part of the tax refund documents. During the audit, the consistency of the query channel, time, result of the certification number and the tax refund declaration information will be checked. If the entrusting party queries by itself, it needs to take a screenshot to save the complete information of the query page, including query time, certification number, corresponding customs declaration form number, etc., to avoid audit failure due to inability to provide query records. If the query result shows that the certification number has been used, you need to verify whether there is a situation where the agency enterprise reuses the certification number, and report to the tax authority in time and apply for correction, so as to avoid the tax refund being recovered due to repeated declaration. **status:** suggested **Author:** Michael Zhang **Date:** 2026-10-13 ### Answer 6 From the perspective of on-site customs inspection, the consistency of the information between the export agent certification number and the customs declaration form is one of the key verification contents of on-site inspection. If the queried certification number does not match the agency information on the customs declaration form, it may lead to the goods being temporarily detained and inspected by the customs, increasing additional costs such as port detention fees and container detention fees. When querying, you need to ensure that the issuance date of the certification number is earlier than the export date of the goods. If the issuance date of the certification number is later than the export date, you need to contact the agency enterprise to apply to the customs for adjusting the issuance date of the certificate, so as to avoid being identified as document violation during on-site inspection and affecting the normal customs clearance of the goods. **status:** suggested **Author:** Linda Gao **Date:** 2026-10-13 ### Answer 7 From the perspective of supply chain planning, the query efficiency of the export agent certification number directly affects the capital turnover cycle of the enterprise and the smooth operation of the supply chain. It is recommended that when entrusting an agent for export, the enterprise agrees on the query time node of the certification number with the agency enterprise, and requires the agency enterprise to complete the issuance and filing of the certificate within 5 working days after the export of the goods, and simultaneously provide the query channel and method. At the same time, the query of the certification number can be incorporated into the supply chain management system to realize information linkage with customs declaration, tax refund, payment and receipt and other links, so as to avoid supply chain node delay caused by information lag and affect subsequent order delivery. **status:** suggested **Author:** Andy Guo **Date:** 2026-10-13 ## Related Categories - [Import Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-import-agency/) - [Export Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-agency/) - [Customs Declaration Q&A](https://www.sh-zhongshen.com/en/qa/cat-customs-declaration/) - [Freight Forwarding Q&A](https://www.sh-zhongshen.com/en/qa/cat-freight-forwarding/) - [Forex Settlement Q&A](https://www.sh-zhongshen.com/en/qa/cat-forex-settlement/) - [Entrepôt Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-entrepot-trade/) - [General Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-general-trade/) ## Related Resources - [Trade Services](https://www.sh-zhongshen.com/en/services/) - [Trade Cases](https://www.sh-zhongshen.com/en/cases/) - [Trade Wiki](https://www.sh-zhongshen.com/en/wiki/) - [Trade Class](https://www.sh-zhongshen.com/en/guide/) - [Global Trade Services](https://www.sh-zhongshen.com/en/country/) ## Structured Data ```json [ { "@context": "https://schema.org", "@type": "QAPage", "inLanguage":"en", "isPartOf": { "@id":"https://www.sh-zhongshen.com/en/#website" }, "publisher":{ "@id":"https://www.sh-zhongshen.com/en/#organization" }, "mainEntity": { "@type": "Question", "name": "What official compliance query channels are available for export agent certification numbers when handling export tax refund business?", "text": "I am the head of a small foreign trade factory of household goods in Shanghai.
