2026 Full Guide to Agent Export Process: One-Stop Operation from Customs Declaration to Tax Refund

Core Breakdown of Full Agent Export Process for Goods (2026 Edition)

Against the backdrop of global supply chain restructuring in 2026,agent export has become the core choice for small and medium-sized foreign trade enterprises to access overseas markets compliantly.As an agent expert with 20 years of in-depth experience in Shanghai Port,I have seen too many enterprises encounter pitfalls due to unfamiliarity with the process: some clients were delayed for 3 days by customs inspection due to incorrect HS code classification,while some enterprises missed RCEP tariff reduction preferences due to failure to apply for certificate of origin.The following is a field-proven full agent export operation guide,covering key nodes from entrustment to foreign exchange receipt.

I.Entrustment Agency Stage: Clarify Boundaries of Rights and Responsibilities

• Lock contract clauses: Trade terms such as EXW/FOB/CIF must be clearly specified in the agency agreement.For example,a furniture factory mistakenly signed FOB clauses during agent export,which led to overseas customers refusing to pay freight,and we finally advanced an extra 3,000 US dollars.
• Qualification document verification: It is required to review the agent’s business license,import and export right certificate,and registration certificate of customs declaration unit (new e-port filing requirement added in 2026).
• Business scope definition: Clearly specify whether services including tax refund declaration,foreign exchange receipt verification and destination port customs clearance assistance are included,to avoid subsequent disputes.

II.Stock Preparation and Document Preparation: Lay a Solid Compliance Foundation

• Accurate HS code classification: Customs strengthened classification inspection in 2026.A lighting enterprise classified LED lights as "lighting equipment" instead of "lamps and lighting devices",which led to the customs declaration form being rejected and tax refund delayed for 2 weeks.It is recommended to conduct pre-review through the Classification Tong system in advance.
• Core document list: Commercial invoice (must include elements of the new version of electronic invoice launched in 2026),packing list,certificate of origin (HS code + exporter declaration required for RCEP member countries),customs declaration authorization letter.
• Extra preparation for special categories: MSDS (for chemicals),3C certification (for electronic products),dangerous goods packaging certificate (for dangerous goods) and other documents shall be provided for relevant goods,none of which can be missing.

III.Shanghai Port Customs Declaration and Logistics Coordination (Latest Service Advantages in 2026)

Note: Zhongshitong relies on the AEO senior certification qualification of Shanghai Customs,and can apply for the "advance declaration" mode,enabling 90% of goods to be picked up immediately upon release.

IV.Destination Port Certification and Anti-dumping Early Warning (Must-read for Enterprises)

Certification requirements for imported products vary greatly in different countries.The update of EU REACH regulation newly launched in 2026 has led to product returns for 12% of export enterprises.

• US FDA Certification: Product ingredient list shall be submitted 90 days in advance.A new electronic submission system was launched in 2026,and Zhongshitong can provide pre-review services
• Special requirements for Middle East market: Saudi SASO certification shall be completed at the production place of goods.An enterprise failed to handle it in advance,resulting in goods being detained at Jeddah Port for 5 days and incurring port demurrage of 40,000 US dollars
• Anti-dumping duty avoidance: Focus on the 38.6% anti-dumping duty rate imposed on Chinese bicycles by the US Department of Commerce in 2026.It is recommended to adopt the combined scheme of "certificate of origin + third-country assembly"

V.Dual Guarantee of Export Tax Refund and Foreign Exchange Receipt Security (Key Optimization Points in 2026)

Foreign exchange receipt and tax refund are the core value points of agent export.The State Taxation Administration issued new regulations in 2026: tax refund declaration requires "three-document matching" with export customs declaration form (customs declaration form,export invoice,foreign exchange receipt voucher).

(1) Practical Operation of Tax Refund Optimization

• Key to pre-review: Submit documents 3 days before declaration.Zhongshitong can lock the tax refund rate in advance through the "electronic tax refund rate query system" (tax refund rate for some chemical products increased from 9% to 13% in 2026)
• Special handling: For the situation of "tax refund first and certificate supplement later",the "Certificate of Tax Paid (No Tax Refund) for Returned Export Goods" shall be prepared in advance

(2) Foreign Exchange Receipt Security Scheme

A toy enterprise in Ningbo received foreign exchange through a third-party payment platform.In March 2026,the platform froze funds,resulting in failure to process tax refund.Zhongshitong recommends adopting the combination of "T/T telegraphic transfer + bank guarantee":

• Require customers to pay directly to the designated account of Zhongshitong via telegraphic transfer
• Bank payment guarantee is mandatory for large orders (over 500,000 US dollars)
• Monitor foreign exchange fluctuations in real time.The fluctuation range of RMB against US dollar reached ±5.2% in 2026,and it is recommended to use forward foreign exchange settlement to lock the exchange rate

VI.2026 Agent Export Pitfall Avoidance Guide (Expert Experience)

I once assisted a Suzhou enterprise in handling a typical case: the agent failed to verify the "fake certificate of origin" provided by the customer,and the goods were identified as fraud by EU customs at Hamburg Port,leading to the decline of the enterprise’s credit rating.

• Mandatory verification: Require the agent to provide the electronic ledger of certificate of origin (new requirement added in Announcement No.35 of the General Administration of Customs in 2026)
• Document consistency: The shipping mark on the packing list must be completely consistent with the bill of lading,otherwise additional amendment fee will be incurred for destination port customs clearance
• Exchange rate locking: When signing a forward foreign exchange settlement agreement with the bank,the clause of "automatic adjustment when exchange rate fluctuation exceeds ±3%" shall be clearly specified

Final reminder: The essence of agent export is "risk transfer and efficiency improvement".When selecting an agent,focus on its national port linkage capability and interpretation capability of the latest policies in 2026.Relying on the resources of its Shanghai headquarters,Zhongshitong can realize "entrustment in one place,customs clearance nationwide".For details,please feel free to consult (Note: This is for content description only,and the actual contact information shall be subject to the official release).
