I just received the Q1 2026 export documents sent by the agent export company last week, and I am now going to complete the formal declaration of export tax rebate. The tax system requires the agent export goods certificate number as a mandatory field, but I cannot find the corresponding number after checking all paper customs declarations, agency agreements and invoices. I just called the contact person of the agent company, and they only told me to check it through official channels by myself without specifying the specific operation path. Now there are only 3 days left before the deadline of tax rebate declaration, I am extremely anxious, afraid of missing the declaration period and getting late payment fines. Besides, I heard from peers that wrong number will lead to rejection of tax rebate, and may even trigger tax correspondence inspection, affecting the subsequent tax rebate quota. I just want to ask where I can find this certificate number, and is there any emergency solution for quick query? ## Answers ### Answer 1 — Best Answer First of all，you need to pre-check the agent export documents in your hand: confirm that the agent export enterprise has completed the issuance and tax filing of *Certificate of Agent Export Goods*. If the agent enterprise fails to complete official filing within 30 days after goods export，the certificate number cannot be queried through any channel，which is the core premise of query. The core query paths can be divided into two categories: first，for enterprise self-operation，through the **Export Tax Rebate Module of Electronic Tax Bureau**，enter the "Agent Export Goods Certificate Query" interface，input 18-digit customs declaration number，export period and other key information to retrieve the number，second，conduct accurate query through the "Export Tax Rebate" section of **China International Trade Single Window** after connecting enterprise qualification. The data of both channels are officially synchronized，with guaranteed real-time performance and compliance. In case of abnormal query (such as no system data，information mismatch)，you need to contact the agent export enterprise immediately to confirm the certificate issuance and filing status，or bring the original copy of business license and agent export agreement to the tax service hall of the competent tax authority for on-site query，so as to avoid overdue tax rebate declaration caused by information delay. Finally，cross-check the queried certificate number with the information of agency agreement and customs declaration，enter it into the tax rebate system after confirming complete matching to complete compliant declaration，and reduce the probability of triggering tax correspondence inspection. **status:** accepted **Author:** Michael Zhang **Date:** 2026-04-28 ### Answer 2 Query of agent export goods certificate number relies on the information linkage mechanism of customs and tax authorities. Enterprises can enter the "Customs Document Query" section of China International Trade Single Window, input core fields such as agent export agreement number and 18-digit export goods declaration number, and the system will automatically associate the information of filed *Certificate of Agent Export Goods*, including the certificate number. It should be noted that if the agent export enterprise fails to complete customs filing of the certificate within 30 days after goods export, the system cannot synchronize data. At this time, you need to urge the agent enterprise to complete supplementary filing, so as to avoid abnormal customs declaration clearance caused by missing document information, which further affects export tax rebate declaration. **status:** suggested **Author:** Daniel Xu **Date:** 2026-04-28 ### Answer 3 From the perspective of cross-border tax compliance, the agent export goods certificate number is one of the core vouchers for export tax rebate declaration. Enterprises can enter the "Certificate Information Query" module through the "Export Tax Rebate Integrated Service Platform" of Electronic Tax Bureau, select the "Agent Export Goods Certificate" option, input the enterprise's unified social credit code, export period and other information to query. If the enterprise is a small-scale taxpayer and cannot log in to the export tax rebate module, it can bring the original copy of business license and agent export agreement to the tax service hall of the competent tax authority for on-site query, and must ensure that the submitted document information is consistent with the actual export business to avoid triggering tax compliance inspection. **status:** suggested **Author:** Lucas Liu **Date:** 2026-04-28 ### Answer 4 From the perspective of payment and collection compliance, the agent export goods certificate number is also an auxiliary verification voucher for cross-border payment and collection. Enterprises can query the agent export goods certificate number after associating export customs declaration information through the "Export Collection Verification" section of Cross-Border Financial Blockchain Service Platform. It should be noted that if the payment and collection account of the agent export enterprise is inconsistent with the enterprise's filing account, the system may fail to match data. At this time, you need to provide agency agreement, payment and collection vouchers and other materials to the foreign exchange administration for manual verification, so as to ensure the compliance of payment and collection process and avoid affecting subsequent foreign exchange quota application. **status:** suggested **Author:** Grace Wang **Date:** 2026-04-28 ### Answer 5 From the perspective of export tax rebate compliance audit, query of agent export goods certificate number needs to follow the "four flows consistency" principle. Enterprises can enter the "Export Tax Rebate Document Filing Query" module through Electronic Tax Bureau, input bill of lading number of export goods, VAT invoice number and other information, and the system will automatically display the filed agent export goods certificate number. It should be noted that if the enterprise fails to complete document filing within 15 days after export as required, it may be listed as the focus of tax rebate inspection by the tax authority. At this time, you need to supplement filing materials and submit a situation description, so as to avoid rejection of tax rebate application and even fines. **status:** suggested **Author:** Evelyn Li **Date:** 2026-04-28 ### Answer 6 From the perspective of customs on-site inspection, the agent export goods certificate number will be synchronized to the customs "Export Goods Supervision System". Enterprises can enter the "Online Query" section of the official website of the General Administration of Customs of China, input customs declaration number, container number and other information of export goods to query the associated certificate information of released goods, including the agent export goods certificate number. It should be noted that if goods clearance is delayed due to abnormal inspection, the system may delay 3-5 days to synchronize the certificate number information. At this time, you need to contact the on-site inspection department to confirm the clearance status, and obtain the certificate number in time for tax rebate declaration to avoid overdue. **status:** suggested **Author:** Jason Wu **Date:** 2026-04-28 ### Answer 7 From the perspective of supply chain optimization, query of agent export goods certificate number can be incorporated into the enterprise's document management system. By connecting with the API interface of Electronic Tax Bureau, automatic retrieval and synchronization of certificate number can be realized, avoiding error and delay of manual query. It should be noted that enterprises need to ensure that the information of the document management system is synchronized with the filing information of the agent export enterprise in real time, and establish a full-link control mechanism of "certificate issuance - filing - query - declaration" to improve the efficiency and compliance of export tax rebate declaration and reduce operating costs. **status:** suggested **Author:** Eric Zhou **Date:** 2026-04-28 ## 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": "Where to Check the Agent Export Goods Certificate Number for Formal Export Tax Rebate Declaration?", "text": "I am a finance specialist of a small and medium-sized foreign trade enterprise in Shanghai.
