I am the person in charge of a hardware and building materials factory based in Shanghai. Last month, I commissioned Zhongshen as the agent for an export order of 20 containers of galvanized steel pipes bound for Germany. The profit margin of this order is only 8%, and we rely entirely on export tax refund to cover the cost gap.

When I handled export tax refund on my own in 2025, a one-word difference in the product name between the customs declaration form and the VAT invoice triggered letter verification from the tax authority. It took 3 months to finalize the process, and I incurred more than RMB 20,000 in overdue tax surcharges. I was so anxious that I visited the tax bureau every day back then.

Now I hear that the four-flow consistency requirement for agency-based tax refund is stricter, and there are various pitfalls in pre-declaration and document filing. I am especially worried about repeating the same mistake. I would like to know the full process details of your agency tax refund service, what documents need to be prepared in advance, how to quickly cut losses in case of abnormalities, and whether you can help me minimize tax refund risks?

We focus on checking 100% matching of product name，specification and quantity，with the error controlled within 0.3%. We will also verify the compliance of the foreign exchange collection account to avoid tax refund suspension caused by non-compliant accounts.

Core node connection: Relying on the 2026 "Export Tax Refund Intelligent Pre-review System" of Shanghai Municipal Tax Service，we will complete pre-declaration within 10 working days after the goods are declared for export，and simultaneously coordinate with the customs to obtain the tax refund copy of the export customs declaration form. We will submit the formal declaration immediately after the pre-declaration passes verification to ensure no gaps between nodes and avoid overdue tax surcharges caused by delayed declaration.

Exception response plan: If tax authority letter verification is triggered，we will launch an exclusive response team within 24 hours，coordinate with you to provide supporting materials such as factory production records and logistics vouchers，and connect with the exclusive liaison of the tax authority to shorten the letter verification period to less than 15 working days.

For the customs declaration link of agency export tax refund, it is necessary to strictly follow the 2026 "Intelligent Customs Declaration Verification Rules" implemented by Shanghai Customs. The product name and HS Code on the customs declaration form must be completely consistent with those on the VAT invoice. If there is an error in HS Code classification, it will not only lead to the rejection of tax refund review, but also trigger customs classification questioning, and even bring anti-smuggling risks. When declaring customs, accurate data such as the weight, volume and packaging method of the goods shall be uploaded simultaneously to avoid inconsistency between the customs declaration form and the logistics document caused by data deviation.

If you need to modify the customs declaration form, you shall submit the modification application within 7 working days after export. Overdue applications will not be accepted, which will directly affect tax refund declaration. In addition, it is necessary to ensure that the "domestic source of goods" on the customs declaration form is consistent with the location of the VAT invoice issuer, otherwise it will be identified as four-flow inconsistency by the tax authority and trigger letter verification.

In 2026, tax planning for foreign trade agency export tax refund can combine "VAT deferment" and "fast tax refund channel" to optimize costs: If the order destination is an EU country, you can apply for EU VAT deferment through the agency company, no need to pay import VAT in the importing country, and directly use this part of funds to offset domestic VAT, reducing capital occupation costs. If the issuing date of the special VAT invoice is within 30 days after export, you can enjoy the "fast tax refund channel" of Shanghai Municipal Tax Service, and the tax refund crediting time can be shortened to less than 10 working days.

In addition, avoid collecting foreign exchange through personal accounts, otherwise it will be identified as capital backflow by the tax authority and trigger tax refund review risks. It is recommended to use the compliant foreign exchange collection account of the agency company.

The agency agreement for agency export tax refund shall clearly specify the division of responsibilities for tax refund. For agency export tax refund dispute cases handled by Shanghai High People's Court in 2026, it is clearly required that the agency agreement shall specify the specific standards of "four-flow consistency", handling methods for abnormal tax refund, the party bearing overdue tax surcharges and other contents.

If the agency company fails to complete tax refund declaration as agreed, it shall bear corresponding liability for breach of contract, including compensation for overdue tax surcharges, interest and other losses. In addition, avoid setting "catch-all clauses" in the agency agreement, otherwise it will be deemed as invalid clauses by the court. If there is a tax refund dispute, you can safeguard your legitimate rights and interests through arbitration or litigation, and provide a full set of evidentiary materials including agency agreements, document materials, communication records, etc.

The 2026 "Logistics Information Linkage System" implemented by Shanghai Customs will automatically compare data such as product name, quantity and weight between the logistics document and the customs declaration form.

The consignor on the logistics bill of lading shall be consistent with the name of the agency company, and the consignee shall be consistent with the name of the overseas purchaser, to avoid bill of lading endorsement errors.

If there is logistics delay, a "logistics delay explanation" shall be submitted together with the delay certificate issued by the shipping company within 10 working days after export, otherwise it will be identified as abnormal export by the tax authority and trigger tax refund review risks. In addition, it is necessary to ensure that the transportation method on the logistics document is consistent with that on the customs declaration form, otherwise it will affect the compliance of tax refund declaration.
