In 2026,Shanghai’s total foreign trade import and export volume increased by 8.2% year-on-year,with general trade exports accounting for more than 60%.However,many foreign trade enterprises reported that cargo is often detained at ports in the export customs clearance link due to unfamiliarity with procedures and incorrect documents,with an average delay of 3 to 5 days and direct losses of over ten thousand yuan in freight and storage fees.Export customs clearance procedures are the "last mile" for goods to be transported from China to abroad,and also a high-risk link.Combining 20 years of industry experience from Zhongshen,this article systematically breaks down the core processes of export customs clearance to help you avoid common pitfalls.

I.Core Stage Breakdown of Export Customs Clearance Procedures

1.Preparatory Stage: Complete Documents Are the Foundation of Customs Clearance

The goal is to ensure all declaration materials meet customs requirements and avoid document rejection.Key actions include: verifying foreign trade contracts,commercial invoices,packing lists,customs declaration forms (draft),completing inspection for legally inspected goods in advance,and providing dangerous goods packaging certificates for special goods (such as hazardous materials).

Common issues:

• Inconsistent document information: For example,the invoice amount does not match the contract,and the weight on the packing list deviates from the actual goods
• Missing inspection for legally inspected goods: Some textiles,food,etc.fall under the scope of legal inspection,and direct declaration without inspection will lead to document rejection
• Incorrect filling of customs declaration form elements: Such as errors in commodity codes,origin and other information

Role of Zhongshen:

• Preliminary review of all documents: Manager Lei’s team will check each document three times to ensure information consistency
• Remind of inspection deadlines: Remind customers of legally inspected goods to complete inspection 10 working days in advance,and coordinate with inspection institutions to speed up the process
• Commodity code verification: Use the latest customs database to accurately match commodity codes,avoiding increased inspection rate due to code errors

2.Declaration and Inspection Stage: Accurate Declaration Reduces Inspection Rate

The goal is to smoothly pass customs electronic declaration and on-site inspection,and quickly enter the release link.Key actions include: submitting electronic declaration through the Single Window of the General Administration of Customs,cooperating with customs to open boxes for inspection if selected,and verifying whether the goods match the documents.

Common issues:

• Non-cooperation during inspection: Some enterprises are unfamiliar with the inspection process,leading to prolonged inspection time
• Missing declaration elements: For example,key elements such as food ingredients and origin are not filled in
• Mismatch between goods and documents: The actual brand of the goods does not match the declaration,or there is a difference in quantity

Role of Zhongshen:

• Special personnel accompany inspection: If the goods are selected for inspection,Manager Lei will arrange an experienced customs declarer to accompany on-site and answer customs questions
• Declaration element optimization: Supplement and improve declaration elements according to the 2026 latest customs requirements,reducing the inspection rate to below 5% (industry average is 12%)
• Pre-inspection of goods: Assist customers in verifying the information between goods and documents before the goods are put into storage,avoiding mismatch issues

3.Tax Payment Stage: Pay Taxes in Time to Avoid Late Fees

The goal is to accurately calculate and pay taxes in time to ensure smooth release of goods.Key actions include: confirming the tax payment form issued by the customs,paying tariffs,value-added tax,and consumption tax (if required) through the Single Window or bank,and some goods can enjoy the export tax rebate policy.

Common issues:

• Incorrect tax calculation: Some enterprises are unfamiliar with tariff rates and VAT deduction policies,leading to overpayment or underpayment
• Delayed payment: Failure to pay taxes in time results in a late fee of 0.05% per day
• Lack of understanding of tax rebate policies: Goods eligible for tax rebates are not declared in time,missing the tax rebate deadline

Role of Zhongshen:

• Accurate tax calculation: Connect to the customs system,update tax rates in real time,and accurately calculate the taxes payable
• Diversified payment channels: Provide multiple methods such as online payment and bank transfer,and remind payment within 24 hours to avoid late fees
• Tax rebate policy interpretation: In 2026,the export tax rebate rate for some high-tech products has been increased to 17%.Manager Lei’s team will inform customers in advance and assist in preparing tax rebate materials

4.Release and Shipment Stage: Coordinate Logistics to Ensure Timeliness

The goal is to quickly arrange loading of goods onto ships/aircraft after customs release,avoiding logistics connection delays.Key actions include: confirming customs release information,contacting freight forwarders to arrange shipping space,and verifying bill of lading information to ensure timely shipment of goods.

Common issues:

• Release delay: Some goods require manual review,and failure to track in time leads to release delay
• Shortage of shipping space: Tight shipping space during peak seasons (such as before Christmas) makes it impossible to ship on time
• Incorrect bill of lading information: Errors in consignee,address and other information on the bill of lading affect delivery

Role of Zhongshen:

• Release status tracking: Monitor customs release progress in real time,and coordinate and solve problems in time
• Shipping space reserve: Long-term cooperation with more than 3 mainstream freight forwarders,reserving 10% of shipping space during peak seasons to ensure timely shipment of goods
• Bill of lading verification: Verify bill of lading information three times to avoid delivery problems caused by incorrect information

5.Follow-up Stage: Complete Tax Rebate and Foreign Exchange Settlement

The goal is to complete foreign exchange receipt and payment,foreign exchange settlement and purchase,and export tax rebate to realize capital recovery.Key actions include: collecting foreign payments,settling foreign exchange through banks or agency companies,and preparing tax rebate materials to declare to the tax authorities.

Common issues:

• Delayed arrival of foreign exchange: Some countries have strict foreign exchange controls,leading to prolonged payment arrival time
• Fluctuations in foreign exchange settlement exchange rates: Failure to settle foreign exchange in time leads to exchange rate losses
• Incomplete tax rebate materials: Missing VAT invoices,customs declaration forms and other materials make it impossible to apply for tax rebates

Role of Zhongshen:

• Foreign exchange receipt and payment agency: Provide safe and compliant foreign exchange receipt and payment channels to speed up the arrival of payments
• Exchange rate locking service: In 2026,exchange rates fluctuate greatly,assisting customers in locking exchange rates to avoid losses
• Preliminary review of tax rebate materials: Establish exclusive tax rebate files,regularly remind customers to supplement materials,ensure smooth arrival of tax rebates,and shorten the average tax rebate time to 15 working days (industry average is 25 working days)
