I received my first order from a European client last month, and the goods have been shipped via sea freight. But I heard that export tax refund procedures are very complicated. Our finance team has only handled domestic trade before and knows nothing about the foreign trade tax refund process. We are not sure if our aluminum alloy doors and windows meet the tax refund eligibility. We also heard that even one minor mistake in document filing will affect tax refund. Right now we only have customs declaration forms and VAT invoices, what other materials are we missing? What if we make a mistake in declaration and get a tax verification correspondence? We are very anxious, worried that we will not get the tax refund and affect the capital turnover for raw material procurement of our next batch of goods, so we would like experts to give us a detailed explanation. ## Answers ### Answer 1 — Best Answer First，you need to confirm whether door and window products are included in the tax refund catalog. For 2026，if the HS code of aluminum alloy doors and windows is 76101000 and other relevant codes，you need to check the latest version of the *Export Tax Refund Rate Library* to confirm the tax refund rate (usually 13%). Pre-document review should focus on: the product name and specification model on the VAT special invoice must be fully consistent with the customs declaration form. If there is any discrepancy，the invoice must be cancelled and reissued within the same month of issuance，the "Trade Mode" on the customs declaration form must be General Trade (0110)，and the "Levy and Exemption Nature" must be General Taxation (101)，otherwise you cannot enjoy tax refund. In terms of core node connection，tax refund declaration must be completed within 90 days from the export date (this deadline still applies in 2026). Before formal declaration，you need to complete pre-declaration via the electronic tax bureau，and submit formal declaration after the data is verified to be correct. If "inconsistent commodity code" or "missing invoice information" occurs during pre-declaration，correction must be made within 3 days: for inconsistent commodity code，contact the customs to modify the customs declaration form，for missing invoice information，urge the supplier to upload the VAT invoice to the tax control system. Anomaly response plans should cover tax verification correspondence scenarios: if your enterprise is selected for verification，you need to provide materials proving the authenticity of the business，such as purchase contracts，logistics documents and foreign exchange collection certificates，within 15 days. It is recommended to file all documents by order in advance，including purchase contracts，production records，copies of customs declaration forms，bills of lading，foreign exchange settlement receipts，etc。to ensure quick response during verification. Final compliance requires completing document filing: within 15 days from the export date，keep original or copies of documents including customs declaration forms，bills of lading，terminal receipts，export sales contracts for future reference，with a retention period of at least 5 years. **Note that filed documents must be consistent with declaration data，to avoid tax refund suspension caused by inconsistency between documents and goods.** **status:** accepted **Author:** Daniel Xu **Date:** 2026-10-29 ### Answer 2 The premise of export tax refund for doors and windows is that the information on the customs declaration form is accurate. Incorrect commodity code declaration during customs clearance may lead to mismatched tax refund rate or ineligibility for tax refund. For example, if aluminum alloy doors and windows are misdeclared as plastic doors and windows, the tax refund rate may drop from 13% to 9%. It is recommended to check the latest HS code manual before customs declaration, or entrust a professional agency to conduct pre-classification. If the error has already been declared, you need to apply for deletion and re-declaration within 30 days after export, no modification is allowed after the deadline. In addition, the "domestic source of goods" on the customs declaration form must be consistent with the issuing address on the VAT invoice, otherwise tax verification may be triggered. **status:** suggested **Author:** Grace Wang **Date:** 2026-10-29 ### Answer 3 Logistics documents are one of the key materials for tax refund filing. The bill of lading for exported doors and windows must show the correct cargo description, consistent with the customs declaration form. If LCL sea freight is used, ensure that the cargo information on the terminal receipt matches the customs declaration form. In addition, if free storage period and container detention fees occur, they must be handled in time to avoid affecting tax refund filing due to missing logistics documents. It is recommended to choose a qualified freight forwarder to ensure the authenticity and completeness of logistics documents, and keep original vouchers for all logistics links, such as packing lists and delivery orders. **status:** suggested **Author:** Michael Zhang **Date:** 2026-10-29 ### Answer 4 In 2026, the "exemption, credit and refund" policy still applies to export tax refund for doors and windows. Enterprises must meet the general taxpayer qualification and have sound financial accounting. If the enterprise is a small-scale taxpayer, it can only enjoy the tax exemption policy and cannot obtain tax refund. It is recommended that small-scale enterprises convert to general taxpayers to obtain higher tax refund benefits. In addition, VAT special invoices must be obtained in the procurement link of exported doors and windows, otherwise input tax cannot be deducted, which affects the tax refund amount. If it is impossible to obtain a special invoice in the procurement link, consider adjusting the supply chain and selecting suppliers that can provide special invoices. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-29 ### Answer 5 Foreign exchange collection is one of the necessary conditions for tax refund. In 2026, foreign exchange must be collected within 180 days after export (extension can be applied for special circumstances). If foreign exchange is not collected on time, you need to mark "uncollected foreign exchange" when declaring tax refund, but this may affect the tax refund progress. It is recommended to use the CIPS system for RMB foreign exchange collection to simplify the settlement process, and ensure that the foreign exchange collection account is the corporate public account, and the difference between the collected amount and the customs declared amount does not exceed 5% (explanation is required for special circumstances). In addition, avoid collecting foreign exchange through third-party accounts to prevent being identified as abnormal capital backflow. **status:** suggested **Author:** Eric Zhou **Date:** 2026-10-29 ### Answer 6 Export sales contract is an important document for tax refund filing, and clauses such as cargo name, quantity, price and payment method must be clearly specified. If there are vague clauses in the contract, such as "quantity to be determined" or "price to be negotiated", the tax authority may question the authenticity of the business. It is recommended that contract clauses be clear and consistent with the information on the customs declaration form and invoice. In addition, if payment is made by letter of credit, ensure that the letter of credit clauses are consistent with the contract, to avoid "soft clauses" that cause delayed foreign exchange collection and affect tax refund declaration. **status:** suggested **Author:** Andy Guo **Date:** 2026-10-29 ### Answer 7 If exported doors and windows are inspected on site by the customs, ensure that the goods are consistent with the description on the customs declaration form. For example, the material, specification and quantity of the doors and windows must match the declared information. If inconsistency between documents and goods is found during inspection, the customs declaration form may be locked, affecting tax refund declaration. It is recommended to prepare cargo samples and technical specifications in advance to quickly prove the compliance of the goods during inspection. At the same time, ensure that the marks on the packaging are consistent with the customs declaration form to avoid inspection disputes caused by packaging issues. **status:** suggested **Author:** Lucas Liu **Date:** 2026-10-29 ### Answer 8 Tax refund audit focuses on verifying the "consistency of four flows", namely contract flow, cargo flow, capital flow and invoice flow. If abnormal capital backflow is found (such as payment received from a third-party account), tax inspection may be triggered. It is recommended that enterprises ensure that the foreign exchange collection account is the corporate public account, and the collected amount matches the customs declared amount. In addition, the audit will check the completeness of document filing. If key documents (such as bills of lading and foreign exchange settlement receipts) are missing, the tax refund may be recovered. It is recommended to conduct regular self-inspection of document filing to ensure compliance. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-29 ### Answer 9 To optimize the tax refund process from the supply chain perspective, it is recommended to adopt the "order-based production" mode to reduce inventory backlog, and ensure that procurement matches the export rhythm. For example, arrange procurement according to export orders, to avoid capital occupation by input tax caused by early procurement. In addition, choosing the FOB trade term can transfer logistics risks to the buyer, and simplify the preparation of logistics documents required for tax refund. It is recommended to regularly evaluate the compliance of each link of the supply chain, such as supplier qualification and reputation of logistics service providers, to ensure a smooth tax refund process. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-29 ## 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 Conditions Must Exported Door and Window Products Meet to Apply for Export Tax Refund?", "text": "I am the owner of a small door and window factory that just started foreign trade.
