Full Process of Import & Export Agency: Guide to Customs Declaration, Tax Refund and Foreign Exchange Collection Risk Control

Core Business Modules of Import & Export Agency

As a practitioner with 20 years of experience in foreign trade agency,I have seen too many enterprises stumble in links such as customs clearance,tax refunds,and foreign exchange collection due to vague understanding of agency responsibilities.Import & export agency is by no means a simple "errand-running service",but a full-link risk control expert from overseas market compliance to domestic policy implementation.In 2026,we helped clients resolve 92% of trade disputes through the "Four-Step Tackling Method",with the most typical case being that of a machinery manufacturing enterprise:

This enterprise exported machine tools to Germany for the first time,and its products were detained by customs at the Port of Hamburg for failing to meet the "EMC (Electromagnetic Compatibility) requirements" in the EU CE certification.Relying on our familiarity with the policies of the German Federal Customs,we completed the rectification plan within 3 days,while coordinating with our partner laboratory in Germany for expedited testing,and finally avoided a detention fine of 270,000 euros.

I.Full Process of Compliance Certification for Overseas Destination Countries

Certification requirements for imported goods vary greatly among different countries,which is the first firewall of agency services.Taking the EU Carbon Border Adjustment Mechanism (CBAM) newly implemented in 2026 as an example,we have established a "Three-Stage Certification System":

• Pre-Certification Stage: Verify whether the product is included in the EU carbon tax list 3 months in advance.For categories newly added in 2026 such as lithium batteries and textiles,carbon footprint data must be highlighted
• Pre-Examination of Documents: Ensure that the header of the Certificate of Origin (CO) completely matches that of the Bill of Lading (B/L).A furniture enterprise once had its goods detained by Belgian customs due to an extra space in the header.The agency coordinated with the shipping company to replace the documents urgently,recovering 12 days of detention losses
• Port Emergency Handling: For dangerous goods (such as chemicals),it is mandatory that the MSDS (Material Safety Data Sheet) report is consistent with the actual composition of the goods.In 2026,a chemical enterprise experienced customs clearance delays in the Netherlands due to an outdated MSDS.We obtained a new version of the report quickly through the Shanghai Research Institute of Chemical Industry and resolved the problem within 48 hours

Key Term Explanation

II.Dynamic Early Warning of Anti-Dumping and Trade Barriers

The number of global trade barriers increased by 18% year-on-year in 2026,and anti-dumping early warning has become the core competitiveness of agency services.We have established a "Three-Dimensional Monitoring System":

• Policy Radar: Track trade restriction measures notified by the WTO every week.In March 2026,the United States launched a "sunset review" on Chinese photovoltaic modules.We notified cooperating enterprises 15 days in advance to adjust their export strategies
• Tariff Rate Calculator: Enter the HS code to generate the tariff rate of the target country in real time.In 2026,the EU reduced the anti-dumping duty on Chinese stainless steel tableware from 42% to 38%.We assisted clients in applying for tariff reduction,saving approximately 1.5 million yuan in costs
• Case Database Comparison: Cross-verify past cases of similar products with current declaration data.An auto parts enterprise was levied a 12% anti-dumping duty due to failure to detect "HS code classification error".The agency recovered the losses through classification adjustment

Practical Guide to Avoid Pitfalls

Note: Anti-dumping early warning is not just "knowing the tariff rate in advance",but "dynamically adjusting declaration parameters".Once,a client exported textiles to India.We found that the declared "fabric composition" did not match the actual one (5% more cotton content).Although it did not directly involve anti-dumping,it invalidated the Certificate of Origin (FORM A),and finally a 20% punitive tariff was levied at the destination port.

III.Export Tax Refund Optimization and Declaration

The export tax refund policy was further simplified in 2026,but there are still many pitfalls in practice.We have summarized a "Five-Dimensional Optimization Model":

• Code Accuracy: In the 2026 customs code adjustment,the code for "Bluetooth speakers" was changed from 85189090 to 85181090.An electronic enterprise saw a 30% reduction in tax refund amount due to misdeclaration.The agency avoided the risk through the "pre-audit of classification" service
• Document Matching Degree: Ensure that the interval between the issuing date of the VAT invoice and the export date on the customs declaration form does not exceed 90 days.A garment enterprise was required to provide a "non-deduction certificate" due to early invoicing,delaying the tax refund for 3 months
• Exchange Rate Locking: Apply for "export tax refund exchange rate locking" simultaneously when settling foreign exchange.In 2026,the exchange rate fluctuated by 12%.We helped clients lock the exchange rate at 6.82,earning 2.3 percentage points more than the market price
• Special Supervision Zones: Enterprises in the Shanghai Free Trade Zone can enjoy the "tax refund upon departure" policy.In 2026,a "declaration-refund immediately" channel was added,reducing the average tax refund cycle from 15 days to 7 days
• Risk Isolation: For enterprises engaging in "buying export documents",it is mandatory to achieve "triple flow consistency" (goods flow,capital flow,document flow).A foreign trade company was identified as tax fraud due to "quadruple flow inconsistency".The agency recovered losses of 12 million yuan through legal channels

IV.Foreign Exchange Collection Security Guarantee System

The proportion of cross-border RMB settlement reached 34% in 2026,but 45% of enterprises still encountered problems due to foreign exchange collection paths.We have built a "Dual-Track Foreign Exchange Collection Mechanism":

Practical Exchange Rate Management

In June 2026,a toy enterprise received an order of 1 million US dollars,with the exchange rate at 6.89 at that time.We recommended the combination of "forward foreign exchange settlement + option hedging".Three months later,the exchange rate dropped to 6.78,and the enterprise locked in a profit of 210,000 yuan by exercising the option.This reflects the value-added of "non-financial services" in agency services.

V.2026 Import & Export Agency Service Checklist

Based on customer feedback in 2026,we have compiled a necessary "Five-Dimensional Risk Checklist" for enterprises to self-check against:

• Customs Declaration Document Checklist: Sales Contract (S/C),Invoice,Packing List,Customs Declaration Form (10-digit code),Bill of Lading (B/L),Certificate of Origin (CO)/FORM A
• Special Supervision Certificates: 3C Certification (home appliances),Endangered Species Certificate (timber),Export License (rare earths),Automatic Import License (used equipment)
• Foreign Exchange Filing Checklist: Filing is required 3 working days in advance if the collection amount exceeds 500,000 US dollars.In 2026,classified supervision of "foreign exchange receipts and payments for service trade" was added
• Qualifications of Importers in Destination Countries: FSC Certification is required in the US,CNPJ Tax ID in Brazil,and GOST Certification in Russia
• Logistics Coordination Checklist: For dangerous goods,the "Marine Dangerous Goods Declaration Form" must be submitted 48 hours in advance; for cold chain goods,full-process temperature control records must be provided

Conclusion

The value of import & export agency lies in integrating scattered compliance requirements,policy changes,and risk points into an executable operation chain.The trade environment in 2026 is becoming more complex,and enterprises need not only "agency services" but also "trade consultants".With 20 years of practical experience,Zhongshitong has established a "7×24 Hour Response Center" at the Shanghai Port to ensure that each link can achieve closed-loop services of "pre-warning,in-process control,and post-review".
