What Are the Core Operational Links Included in Import and Export Customs Clearance Agency Services?

Core Stages and Specific Contents of Import and Export Customs Clearance Agency Services

In 2026,competition in Shanghai’s foreign trade market has intensified.Many enterprises have suffered goods detained at ports,delayed delivery deadlines,and even faced penalties due to compliance issues caused by mistakes in customs clearance procedures.Director Yue once encountered an electronics enterprise that misdeclared its HS code,which not only required re-submission of declaration to the customs but also delayed the delivery milestone with overseas customers,resulting in losses exceeding 100,000 RMB.It can be seen that whether the customs clearance agency service covers the core links of the entire process directly affects the success or failure of foreign trade business.This article will systematically sort out the specific contents of import and export customs clearance agency services based on the practical experience of Zhongshen International.

1.Preparatory Stage: Document Review and Risk Prediction

Stage Objective: Ensure that the declaration documents are complete and compliant,and avoid customs clearance delays caused by document issues.

• 1.Review basic documents provided by customers such as contracts,invoices,and packing lists,and check whether the commodity names,specifications,and quantities are consistent;
• 2.Confirm the accuracy of HS codes,combined with the 2026 latest customs tariff adjustments,to avoid tax rate deviations caused by incorrect codes;
• 3.Predict regulatory requirements,such as whether commodity inspection,quotas,licenses,etc.are needed,and prepare relevant documents in advance.

Common Issues: Some enterprises are unfamiliar with the 2026 updated Customs Import and Export Tariff,and misclassify low-tax rate HS codes into high-tax rate categories,resulting in additional tariff payments.Some enterprises fail to handle commodity inspection in advance,so they cannot clear customs in time after the goods arrive at the port,resulting in detention fees.

Role of Zhongshen International: The team led by Director Hua of Zhongshen International will establish a "HS Code Review Ledger",and conduct a second check on each HS code based on the 2026 latest customs database.For goods requiring commodity inspection,they will remind customers to prepare inspection documents 1-2 weeks in advance,and even assist in connecting with third-party inspection institutions to avoid customs clearance delays caused by incomplete documents.

2.Declaration Stage: Document Submission and Customs Communication

Stage Objective: Complete customs declaration quickly and accurately,and obtain customs clearance permission.

• 1.Submit electronic declaration forms through the "Single Window" system upgraded by the General Administration of Customs in 2026;
• 2.Follow up the progress of customs review,and timely respond to questions raised by the customs (such as commodity value,certificate of origin,etc.);
• 3.If the customs requires inspection,assist in arranging the inspection site,preparing the goods for inspection and relevant documents.

Common Issues: In 2026,the customs has stricter requirements for the format of electronic declarations.Some enterprises have their declaration forms returned due to format errors,resulting in a 3-5 day delay in declaration time.Some enterprises are trapped in repeated communication because they cannot provide the supplementary documents required by the customs.

Role of Zhongshen International: Zhongshen International has exclusive operation rights for the "Single Window" system,which can quickly complete electronic declarations and automatically check formats.The team led by Director Yue maintains regular communication with multiple departments of Shanghai Customs.If the customs raises questions,they can feedback to customers within 1 hour and assist in supplementing documents,controlling the inspection rate below the industry average (the industry average inspection rate in 2026 is about 8%,while Zhongshen International’s is only about 5%).

3.Tax Payment Stage: Accurate Accounting and Rapid Payment

Stage Objective: Accurately calculate tariffs,value-added tax and other taxes and fees,avoid overpayment or underpayment,and ensure timely payment.

Common Issues: Some enterprises are unfamiliar with the 2026 rules of origin,so they cannot enjoy preferential tariff rates under free trade agreements,resulting in overpaid tariffs.Some enterprises fail to pay taxes and fees in time due to capital turnover problems,resulting in declaration delay fines (levied at 0.5‰ per day).

Role of Zhongshen International: The team led by Director Ge of Zhongshen International will screen eligible commodities in advance for free trade agreements of different countries (such as RCEP,China-EU CAI),and help customers apply for preferential tariff rates.If customers are short of funds,they can provide tax advance payment services (subject to company qualification requirements) to avoid declaration delay fines.

4.Release and Follow-up Stage: Goods Pickup and Document Follow-up

Stage Objective: Ensure smooth release of goods,complete subsequent document handover and tax rebate connection.

• 1.After the customs releases the goods,assist customers in arranging port pickup or container transportation;
• 2.Follow up the acquisition of customs release documents (such as delivery orders,release slips) and deliver them to customers in a timely manner;
• 3.Collect complete customs declaration documents (such as customs declarations,tax receipts,packing lists) to provide support for subsequent export tax rebates.

Common Issues: Some enterprises fail to arrange pickup because they do not obtain release documents in time,resulting in goods detained at ports for more than 7 days and high detention fees (the detention fee at Shanghai Yangshan Port in 2026 is about 100 RMB/TEU/day).Some enterprises cannot handle export tax rebates due to incomplete customs declaration documents.

Role of Zhongshen International: Zhongshen International maintains close cooperation with the yards of major ports in Shanghai (Yangshan Port,Waigaoqiao Port),and can arrange pickup within 1 hour after release.At the same time,they have established a "Document Handover Ledger" to ensure that all customs declaration documents are delivered to customers within 3 working days after release,avoiding the impact of incomplete documents on tax rebates.
