I am the head of a small and micro enterprise focusing on outdoor camping equipment based in Shanghai. I just secured a large order of 300,000 euros from a European customer this year, and this is my first time handling export tax refund independently. Previously, we always entrusted freight forwarders to handle the process, but this time we want to handle it by ourselves to cut 10% of our operating costs. When I stayed up late sorting out documents last week, I suddenly found that the first 6 digits of the commodity code on the customs declaration do not match that on the input VAT invoice, and the remark of the foreign exchange settlement receipt also fails to clearly mark the corresponding export batch. Now I am so anxious that I can't sleep through the night. I worry about missing the 2026 declaration deadline, not only failing to get the tax refund of more than 120,000 yuan, but also triggering a tax bureau warning, which may even affect the customs clearance of another batch of goods next month. I want to know how to apply for export tax refund in compliance step by step, how to quickly fix the current document problem, and what common pitfalls I need to avoid?

First complete the pre-document review details: focus on conducting consistency check on the first 6 digits of the commodity code. The tax bureau clearly requires in 2026 that the first 6 digits of the core commodity code on the customs declaration and the input VAT invoice must be fully matched. If there is a discrepancy，contact your customs broker immediately to apply for deletion and re-declaration if the goods have not left the port，if the goods have already left the port，you need to issue a Commodity Code Difference Statement and attach the commodity classification report from a third-party testing institution，for the foreign exchange settlement receipt，you need to add the remark of the corresponding export customs declaration number，and upload it to the "Foreign Exchange Verification" module of China Electronic Port to complete the association.
Core node connection: Log in to the export tax refund declaration module of Shanghai Electronic Tax Bureau. The "one-click pre-audit" function has been upgraded in 2026，and you can get the pre-audit result within 1 hour after uploading the sorted documents. You need to complete the formal declaration within the April VAT filing deadline of the year following the export date，if pre-audit fails，the system will accurately mark the problematic items，and you need to correct and re-upload within 3 working days.
Abnormal contingency plan: If you have already exceeded the declaration deadline，you can submit the Application for Deferred Declaration attached with proof of reasonable reasons (such as the communication letter of customer's overdue payment)，and the tax bureau will approve the extension based on actual situation，if you trigger a tax bureau warning，you need to immediately sort out the proof materials that ensure consistency of goods，invoice，document and foreign exchange (four-flow consistency)，and actively cooperate with the tax bureau's inspection.
Final compliance implementation: After the formal declaration is approved，the tax refund will arrive in your account within 10 working days. You need to keep all documents for inspection for at least 5 years，which meets the 2026 compliance requirements.

Regarding the mismatched commodity code issue between customs declaration and input invoice, if the goods have left the port, you need to first apply to the customs for a Commodity Classification Confirmation Letter, submit detailed specifications, material, usage and other information of the commodity. After the customs issues the confirmation letter, you can submit the confirmation letter together with the Commodity Code Difference Statement to the tax bureau as supplementary basis for tax refund declaration; if the goods have not left the port, you need to contact the customs broker to modify the commodity code before the electronic customs declaration data is sent to the customs, to ensure it is fully consistent with the input invoice, avoiding subsequent tax audit failure.

In 2026, you can combine export tax refund with EU VAT deferral policy to optimize costs. If your European customer agrees to clear customs via VAT deferral, you can mark "VAT Deferral" on the export declaration, so you don't need to pay import VAT in the EU, while your domestic export tax refund will not be affected; note that you need to submit the customer's valid VAT number, deferred clearance agreement and other materials to the tax bureau to ensure compliance, avoiding your tax refund application being rejected by the tax bureau due to incomplete materials.

Export tax refund document filing must strictly follow the 2026 requirements of the tax bureau. You need to organize and bind the customs declaration (export tax refund copy), input VAT invoice (deduction copy), foreign exchange settlement receipt, transport document, export sales contract and other materials, and keep them for inspection for at least 5 years; note that the foreign exchange settlement receipt must correspond to the export customs declaration one by one. If multiple foreign exchange receipts correspond to one export, you need to issue a Foreign Exchange Correspondence Statement, clearly specify the corresponding proportion of each receipt, avoiding doubts during tax bureau inspection.

Regarding the unclear remark issue on foreign exchange settlement receipt, you need to contact your depositary bank to supplement a Foreign Exchange Details Statement, clearly specify the corresponding customs declaration number, export date, commodity name and other information of the received amount, and complete the association filing between the receipt and the export customs declaration via CIPS system; the tax bureau requires in 2026 that foreign exchange collection must be completed within 180 days from the export date. If foreign exchange is overdue due to customer reasons, you need to submit an Overdue Foreign Exchange Statement attached with the customer's delayed payment letter, as the compliance basis for tax refund application.

The export sales contract must clearly mark core information such as commodity code, specification, quantity and amount, to ensure it is fully consistent with the customs declaration and input invoice; if there is a commodity code change, you need to sign a supplementary agreement with the customer in time to clarify the new commodity code, and use the supplementary agreement as supplementary material for tax refund application; note that the supplementary agreement must be stamped with the official seal or business seal of both parties, avoiding rejection of the application due to insufficient validity of the agreement.

If the export goods require on-site inspection, you need to ensure the commodity code on the customs declaration fully matches the actual goods. You need to provide supporting materials such as detailed specification, material and usage of the commodity to the customs during inspection, avoiding mismatched code caused by wrong commodity classification; if the code error is found during inspection, you need to immediately contact the customs broker to apply for modifying the customs declaration, ensuring the code is consistent with that on the input invoice, avoiding compliance doubts in subsequent tax refund audit.
