Customs Brokerage Company Full-Process Compliance Operation Guide for Import and Export

Core Value and Practical Key Points of Import and Export Services Provided by Customs Brokerage Companies

In 2026,global trade rules are iterating at an accelerated pace.From the EU Carbon Border Adjustment Mechanism to US tariff adjustments on Chinese goods,the compliance pressure on import and export enterprises continues to rise.Many enterprises,when declaring on their own,often face cargo demurrage,extra tariff expenses,and even customs penalties due to unfamiliarity with the regulatory requirements of destination countries and incomplete document preparation.The core value of a professional customs brokerage company is to help enterprises avoid these risks through full-link compliance services.

I.Pre-compliance Preparation for Destination Port Customs Clearance Certification

Customs clearance requirements vary drastically across countries.For example,Brazil requires INMETRO certification,Saudi Arabia requires SASO certification,and the EU requires CE marking.Last year,I encountered an auto parts enterprise based in Ningbo that exported 12 containers of auto parts to Brazil.The client designated a freight forwarder but did not prepare the certification in advance,resulting in 10 days of port demurrage after the cargo arrived,and incurred a demurrage fee of 20,000 Brazilian Reals.

Pre-services provided by professional brokers include: checking the certification requirements of the destination country in advance,assisting enterprises in preparing compliant documents,and coordinating the customs clearance process in collaboration with local agents.For instance,in the case mentioned above,we contacted the local agent in Brazil to apply for a temporary certification retroactively,adjusted the tariff rate declared under the corresponding HS code,and finally completed customs clearance in 2 days,reducing 80% of the demurrage fee.

• List of core destination country customs clearance documents: Certificate of Origin,Commercial Invoice,Packing List,Certification Documents,Customs Declaration Form
• Common misconception: Ignoring the impact of public holidays in the destination country on customs clearance efficiency.For example,the carnival season in Sao Paulo,Brazil will cause port congestion

II.Anti-dumping Early Warning and Compliance Risk Mitigation

In 2026,the number of WTO anti-dumping investigations increased by 12% year on year,of which over 60% target Chinese hardware and mechanical and electrical products.For example,Turkey raised the anti-dumping duty rate on Chinese hardware tools from 15% to 22%.A hardware enterprise based in Zhejiang originally planned to export directly.Through our early warning service,it adjusted the quotation in advance and applied for a Certificate of Origin from a third country,saving about 8% of tariff costs in the end.

The key to compliant risk mitigation is: real-time monitoring of changes in global trade policies,accurate HS code classification,and rational utilization of preferential treatment under free trade agreements.For example,Certificate of Origin between RCEP member states qualifies for zero tariff treatment,but many enterprises missed the tax reduction opportunity because they did not apply for the certificate in a timely manner.

III.Practical Skills for Export Tax Rebate Optimization

In 2026,China’s domestic export tax rebate policy was adjusted,and the tax rebate rate for some mechanical and electrical products increased from 13% to 16%.However,many enterprises face delayed tax rebate due to inconsistent information between the customs declaration form and the input invoice.I once met a textile enterprise based in Shanghai that missed filling in "fabric composition" in the declaration elements,leading to a 21-day block in tax rebate review.Later,we assisted in correcting the documents,and the enterprise received the tax rebate funds in just 3 days.

Three core key points for tax rebate optimization:

• Ensure that the product name,quantity and unit on the customs declaration form are completely consistent with those on the input invoice
• Collect compliant documents in a timely manner,including the tax rebate copy of customs declaration form,input invoice,and export contract
• Adjust product quotation and cost structure in accordance with the 2026 latest tax rebate rate policies

IV.Full-Link Risk Control for Foreign Exchange Collection Security

Foreign exchange collection risk is another major pain point for foreign trade enterprises,such as delivery of goods without original bill of lading under FOB terms,and exchange loss caused by exchange rate fluctuations.In 2026,foreign exchange administration policies are further tightened,and enterprises need to handle foreign exchange settlement in a compliant manner.The foreign exchange collection guarantee we provide for clients includes: locking exchange rate to avoid exchange loss,assisting in the processing of current account foreign exchange accounts,and monitoring title documents to prevent loss of cargo ownership.

For example,a cross-border e-commerce enterprise based in Shenzhen previously had its payment received via PayPal frozen.We assisted it in completing foreign exchange collection through legal foreign exchange settlement channels,and locked the exchange rate at the same time,avoiding about 5% of exchange loss.

V.Common Customs Declaration Pitfalls and Risk Early Warning

Pitfalls that many enterprises have encountered include: false declaration/under-declaration of HS codes,incomplete declaration elements,and ignorance of special requirements of destination countries.For example,declaring dangerous goods as general cargo will result in a fine equal to 30% of the cargo value imposed by customs; failure to provide brand and model declaration elements will cause delay in customs price verification.Our risk control system will check these risks in advance and issue compliance reports for enterprises.
