Complete Practical Guide for Manufacturing Enterprises on Eligibility for Export Tax Refund

Core Policy Framework for Manufacturers’ Export Tax Refund in 2026

General Administration of Customs updated the "Specifications for Completing Import and Export Goods Declaration Forms" in 2026,adjusting the document retention period for export tax refund declarations to 5 years,and refining the HS code classification rules for mechanical and electrical,and chemical products.Manufacturing enterprises that meet the tax refund conditions must simultaneously fulfill four basic qualifications: completed record-filing as a foreign trade operator and with customs,obtained an export goods declaration form accessible via the electronic port,goods actually departed from the territory and valid transportation documents retained,and completed compliant foreign exchange collection.In 2026,the tax refund rate for trade within RCEP member states is 1-2 percentage points higher than that of non-member states,provided that an electronically signed FORM R certificate of origin is provided.

Key Points for Basic Qualification Verification

• The record-filing registration form for foreign trade operators must be valid and consistent with the customs record-filing information
• The export goods declaration form must be the tax refund copy officially issued by the electronic port,with no alterations or inconsistent information
• Transportation documents must match the port of departure,port of destination,and departure date of the declaration form; ocean bills of lading must show the actual shipper
• Foreign exchange collection must be completed through the enterprise’s own foreign exchange account.In 2026,the State Administration of Foreign Exchange allows filing for forward foreign exchange collection,but advance registration in the tax system is required

Compliance Red Lines for HS Code Classification and Declaration Elements

The customs control model was upgraded in 2026,and the verification of consistency between declaration elements and physical goods was listed as a core link in the pre-audit of export tax refund.A mechanical and electrical manufacturing enterprise in Suzhou incorrectly classified the HS code of CNC machine tools under 84589100 (ordinary machine tools) when exporting in 2025,which triggered control by Shanghai Port Customs,delaying the tax refund by 3 months and resulting in a capital occupation cost loss of about RMB 80,000.In 2026,this enterprise entrusted Zhongshitong to reclassify to 84589900 (special CNC machine tools),and completed the tax refund audit 7 days in advance.

Compliance points to note: Declaration elements must strictly comply with the 2026 version of HS code notes.For mechanical and electrical products,brand,model,and origin must be marked; for chemical products,MSDS number and hazardous chemicals record number must be provided; for food products,production batch and quarantine number must be marked.It is strictly prohibited to apply similar codes,otherwise customs control will be triggered,leading to an extension of the tax refund cycle by at least 15 days.

Relevance Requirements Between Certificate of Origin and Tax Refund

The requirements for certificates of origin in major global trade regions have been adjusted in 2026,and compliance standards in different regions directly affect the tax refund rate and success rate.Below is a compliance comparison of mainstream trade regions in 2026:

The EU updated the "Implementing Rules for Anti-Dumping Duties" in 2026,adding new origin verification requirements for hardware tools and photovoltaic products exported from China.Manufacturing enterprises must complete electronic record-filing of the certificate of origin 30 days in advance; otherwise,it will be considered a compliance violation and the tax refund cannot be obtained.

Risk Control and Practical Points of Local Agency

Manufacturing enterprises that meet the tax refund conditions still need to avoid three hidden risks in practice: document inconsistency,illegal foreign exchange collection,and classification errors.Zhongshitong relies on the national linkage resources of Shanghai Port to provide one-stop services such as off-site declaration,pre-classification,and document review.Specific practical points include:

• Complete pre-declaration of the declaration form 15 days in advance,and verify that the quantity and amount of goods in the electronic port data are consistent with the enterprise’s financial ledgers
• Retain all tax refund documents for at least 5 years,including declaration forms,transportation documents,foreign exchange collection vouchers,certificates of origin,etc.in line with the 2026 customs new document retention regulations
• Apply to customs for HS code pre-classification for high-risk goods (such as chemical,mechanical and electrical products) in advance to avoid control risks
• Use formal foreign exchange settlement channels; it is strictly prohibited to collect foreign exchange through third parties.In 2026,the State Administration of Foreign Exchange will strictly verify third-party foreign exchange collection acts,and tax refund eligibility will be suspended for violations

In 2026,some manufacturing enterprises had their tax refunds rejected due to failure to complete foreign exchange collection record-filing in a timely manner.Zhongshitong can assist enterprises in quickly completing foreign exchange collection record-filing in the tax system,reducing the tax refund cycle from an average of 22 days to less than 10 days.

Risk Early Warning and Pitfall Avoidance Guide

The State Taxation Administration and the General Administration of Customs established a tax refund data linkage mechanism in 2026,and will implement key verification for export businesses with a declared amount exceeding RMB 1 million.Common violations include: false declaration of goods quantity,tampering with declared amount,and use of false certificates of origin.Such acts will be fined 1 to 3 times the amount of fraudulently obtained tax refund,and the enterprise’s tax refund eligibility will be suspended for 3 years.Manufacturing enterprises need to entrust professional agencies to complete the whole process review of tax refunds to avoid losing more due to small gains.
