2026 Complete Guide to Export Tax Refund for Enterprises

I.2026 Tax Refund Rate Adjustment and Declaration Window Management

Effective January 1,2026,the Ministry of Finance and the State Taxation Administration jointly issued the *Notice on Optimizing Export Tax Refund Services*,involving tax refund rate adjustments for 127 HS code categories.Take machinery products as an example: the tax refund rate for compressors (841430) increases from 13% to 15%,while that for textile fabrics (551410) decreases from 13% to 11%.

Enterprises should focus on three key points: ① Declaration deadline: Tax refund declaration for the previous month shall be completed before the 15th of each month,and a late fee of 0.05% per day will be charged for overdue declarations (data from a Shanghai customs broker in Q1 2026 shows that 23 enterprises suffered total losses of over 1.2 million yuan due to overdue declarations); ② Dynamic HS code classification: For example,the tax refund rate difference between 850710 (other semiconductor equipment) and 850720 (lithography machines) reaches 7%,which requires verification through the pre-classification system; ③ VAT invoice certification time limit: Invoices not certified within 360 days of issuance will not be eligible for tax refund.

Typical Case (S-T-A-R): Situation: A Shanghai-based auto parts enterprise focusing on gearboxes had its tax refund rate reduced from 15% to 9% because its finance team incorrectly classified automatic gearboxes (848310) as other mechanical parts (848390); Task: Zhongshitong detected the classification deviation 3 working days in advance through the Shanghai Port pre-classification platform,and assisted the enterprise in correcting the declaration; Action: The tariff list of imported bearings from Germany was retrieved for comparison to prove the original classification was wrong; Result: A tax refund amount of 538,000 yuan was recovered,and customs inspection risks were avoided.

II.Certificate of Origin Endorsement and Practical Operation of Tariff Reduction and Exemption

In 2026,the RCEP tariff reduction and exemption policy is expanded to 6 countries including Japan and Australia.Enterprises can obtain tariff reduction and exemption through FORM R Certificate of Origin.The following points should be noted in practical operation:

• Accuracy of value-added rate calculation: For example,if the rule of origin requires "regional value content ≥30%",the cost of raw materials (including domestic procurement and imported materials) shall be calculated accurately;
• Consistency of shipping company bill of lading title: When issuing the certificate of origin,it shall be ensured that the "consignor" on the bill of lading is completely consistent with the "operating unit" on the customs declaration form;
• Endorsement time limit: The application shall be completed 3 working days before the shipment of goods.Delay will result in non-retroactive tariff reduction and exemption (a Shanghai garment enterprise lost 42,000 yuan in tariffs due to a 2-day delay in FORM R application).

Featured services of Shanghai Port: Relying on the AEO certification qualification of the free trade zone customs,Zhongshitong can realize "same-day declaration and same-day issuance" of certificates of origin.For example,an LED lighting enterprise exporting to Thailand applied for FORM R through Zhongshitong,and the tariff reduction rate was reduced from the general rate of 12% to 0.8%,saving 87,000 yuan in tariffs per shipment.

III.Consistency of Declaration Elements and Risk Prevention and Control

Announcement No.1 of the General Administration of Customs in 2026 clarifies that inconsistency between declaration elements and actual goods will trigger an "abnormal document" warning,resulting in delayed tax refund.Core warning points include:

• Incorrect filling of model and specification: For example,filling "20W" instead of "200W" caused an electronic component enterprise to be inspected by customs and delay tax refund for 45 days;
• Missing brand information: Imported transit goods not marked with "transit trader brand" lead to failure of certificate of origin verification;
• Deviation in material description: For example,writing "alloy" instead of "stainless steel" led to a kitchenware enterprise’s goods being detained in the EU market due to material disputes.

Zhongshitong’s original "three-review mechanism": First review (enterprise self-review): Verify declaration data through the ERP system; Second review (agency pre-review): Call 10 years of historical data of Shanghai Customs for comparison; Third review (port final review): Assign customs affairs specialists to conduct on-site verification.Data from Q2 2026 shows that this mechanism reduced the declaration abnormality rate from 17% to 3.2%.

IV.2026 New Tariff Regulations and Risk List

Focus on three types of risks:

• Anti-dumping duty warning: The EU maintains a 19.8% anti-dumping duty (AD) on Chinese photovoltaic modules,and enterprises need to lock export volume 30 days in advance;
• Foreign exchange loss hedging: Bank of China’s "special account for export tax refund" can lock the exchange rate,and a Shanghai foreign trade company saved 127,000 yuan in foreign exchange losses through this service in June 2026;
• New access regulations: Saudi SASO certification requirements add "carbon emission label",and non-compliant goods will be detained at Saudi ports.
