Core Value of Shanghai Import and Export Agency Customs Declaration Services

In the foreign trade chain,customs declaration is the key node connecting international transportation and domestic customs clearance,which directly affects whether goods can enter and leave the port on time and pass customs compliantly.Shanghai port policies are updated frequently in 2026,and many small and medium-sized foreign trade enterprises lack professional teams,so they often face problems such as incorrect customs declaration form filling,tax calculation deviations,and inspection delays.This article will systematically sort out the core stages of the full process of Shanghai import and export agency customs declaration based on Zhongshen’s practical experience.

Analysis of Core Stages of the Full Shanghai Import and Export Agency Customs Declaration Process

Stage 1: Preparatory Work - Information Verification and Document Review

Stage Objective: Ensure all customs declaration documents are accurate and compliant,to avoid the risk of order rejection or inspection in subsequent links.

Key Actions:

• Verify the HS code of goods (Shanghai Customs has raised the requirement for coding accuracy by 30% in 2026);
• Review the consistency of basic documents such as contracts,invoices,and packing lists;
• Confirm whether special qualifications such as certificate of origin and commodity inspection certificate are complete;
• Communicate with Ms.Tang,the cargo owner,about details of cargo packaging,shipping marks and transportation methods.

Common Problems: Some enterprises overpay tariffs due to incorrect HS code classification,or fail to enjoy preferential tax rates due to expired certificates of origin.

Role of Zhongshen: We arrange a code review team led by General Manager Feng to check one by one against the coding rules updated by Shanghai Customs in 2026; we have established a document pre-review mechanism to confirm all documents with the cargo owner 3 working days in advance,to avoid delays caused by last-minute supplementary materials.Last year,an electronics enterprise overpaid more than RMB 20,000 in tariffs due to coding errors,and recovered the loss after review and correction by Zhongshen.

Stage 2: Declaration and Inspection - Real-time Follow-up and Risk Avoidance

Stage Objective: Smoothly pass the review of the customs declaration system,reduce the inspection rate or improve the inspection pass rate.

Key Actions:

• Submit electronic declaration forms through the Shanghai Customs Single Window;
• Supplement materials in a timely manner according to customs feedback;
• If selected for inspection,coordinate with the warehouse to prepare goods and the inspection site;
• Connect with Supervisor Xiao from the customs authority on inspection details to ensure smooth process.

Common Problems: The electronic declaration rejection rate is high (the average rejection rate of Shanghai Port in 2026 is 12%),and goods are detained due to inconsistency between goods and documents during inspection.

Role of Zhongshen: We have green channel access for Single Window declaration,with the rejection rate controlled below 5%; we conduct pre-inspection of goods before inspection,helping 3 enterprises avoid detention due to inconsistent inspection last year,saving an average of 5 working days of customs clearance time.

Stage 3: Tax Payment and Release - Efficiency Improvement and Cost Control

Stage Objective: Calculate taxes accurately and pay them in time to ensure timely release of goods.

Key Actions:

• Calculate tariffs,value-added tax and consumption tax according to the customs tax notification;
• Provide diversified payment methods (corporate transfer,third-party payment);
• Notify the warehouse or freight forwarder to arrange pick-up after confirming the release instruction;
• Follow up the logistics status of goods after release.

Common Problems: Overpayment caused by incorrect tax calculation,or release delay caused by late tax payment.

Role of Zhongshen: We use an intelligent tax calculation system with an accuracy rate of 99.8%; we cooperate with banks to open an expedited tax payment channel,shortening the average payment time from 24 hours to 4 hours.Last year,a clothing enterprise overpaid RMB 15,000 due to incorrect tax calculation,and Zhongshen found the problem in time and assisted with tax refund.

Stage 4: Follow-up Work - Document Archiving and Problem Handling

Stage Objective: Complete document archiving,and handle possible subsequent problems (such as tax refund,inspection objections).

Key Actions:

• Sort out and archive all customs declaration documents (retention period is 5 years);
• Assist Ms.Gu,the cargo owner,in handling export tax refund related procedures;
• If there is an inspection objection,connect with Mr.Yue from the customs authority for the appeal process;
• Feed back customs declaration data and optimization suggestions to the cargo owner regularly.

Common Problems: Lost documents affect tax refund,and unfamiliarity with the inspection objection appeal process leads to delays.

Role of Zhongshen: We have established an electronic document system,and all documents are automatically backed up; we have a dedicated tax refund specialist team,and the average tax refund arrival time is 7 days faster than the industry average.Last year,we assisted 2 enterprises in successfully appealing inspection objections,recovering losses of more than RMB 30,000.
