2026 Full-Process Compliance Guide for Agent and Entrusted Export Tax Refund for Enterprises at Shanghai Port

Core Logic of Agent and Entrusted Export Tax Refund and 2026 Policy Changes

In 2026,the General Administration of Customs updated the export tax refund rate library,optimized the electronic networked verification mechanism for certificates of origin,and anti-dumping duty rates for Chinese mechanical and electrical products in the EU and RCEP member states saw partial adjustments.The core of agent and entrusted export tax refund is that foreign trade enterprises accept authorization from the entrusting party,complete export customs declaration,foreign exchange settlement and tax refund processing in their own name,and then transfer the tax refund to the entrusting party.This model can help manufacturing enterprises without export qualification and cross-border e-commerce sellers complete the tax refund process quickly,and avoid verification risks caused by non-standard documents.

Practical Key Points of 2026 New Export Tax Refund Policy

The new policy this year clarifies that complete entrustment agency agreement and export cargo manifest are required for entrusted export goods,and the agent shall mark "entrusted export" in the remark column of the customs declaration form.For goods exported to RCEP member states,electronic filing of certificates of origin shall be completed in advance,otherwise preferential agreement tariff cannot be enjoyed.Meanwhile,the customs has added a new inspection model for high-risk categories,and the customs valuation pass rate of goods with incorrect HS code classification or inconsistent declaration elements dropped by 37%.

Practical Pain Points and Risk Warning of Agent and Entrusted Export Tax Refund

• Incorrect HS code classification: Spot check by the Customs Classification Center in 2026 shows that 32% of tax refund verification failure cases are caused by code classification deviation,directly leading to a tax refund rate difference of up to 6 percentage points
• Inconsistent declaration elements: Inconsistency between declared information such as brand,model and material and the actual goods will trigger customs inspection,delaying the tax refund cycle by up to 21 days
• Non-standard foreign exchange settlement: Remitting payment through third-party accounts without providing corresponding collection receipts will be identified as abnormal transaction by the customs,and the tax refund application will be directly rejected
• Missing endorsement on certificate of origin: For mechanical and electrical products exported to the EU,goods without endorsement of Generalized System of Preferences Certificate of Origin Form A are required to pay an extra 4.5% anti-dumping duty

In February 2026,a hardware manufacturing enterprise in Suzhou entrusted an unqualified team to handle export to Germany.Due to failure to conduct HS code pre-classification in advance,electric wrenches were incorrectly classified as manual tools,the tax refund rate dropped from 13% to 9%,resulting in a loss of 126,000 yuan.After receiving the entrustment,Zhongshitong worked with the Shanghai Customs Classification Center to complete pre-ruling,adjusted the code to the correct category,completed supplementary tax refund declaration within 7 working days,and recovered the full loss.
