Mainland China Import Customs Clearance Agency: Full Process Breakdown and Core Values

Import customs clearance is a key node for mainland enterprises to bring goods purchased overseas into the domestic market.From the departure of goods from overseas to final delivery to customers,clearance efficiency directly affects the speed of capital turnover,while compliance is related to the sustainable development of enterprises’ import business.In 2026,mainland customs has further refined the audit requirements for key categories such as imported food and chemical products.Many enterprises face delays,or even risks of cargo detention and fines due to unfamiliarity with the latest policies or operation procedures.This article,based on Zhongshen’s over 20 years of agency experience,systematically sorts out the core processes of mainland China import customs clearance agency,to help enterprises clarify key points of each link.

I.Pre-preparation: Build the First Line of Defense for Clearance Compliance

Stage Objective: Ensure accurate cargo information and complete documentation,meet the access requirements of mainland customs and commodity inspection authorities,and avoid delays in subsequent links caused by insufficient pre-preparation.

Key Actions:

• Accurately confirm HS Code: Classify goods according to material,purpose,technical parameters and other indicators against the latest 2026 Customs Tariff Schedule,to avoid tax rate deviation or clearance failure caused by incorrect code classification
• Pre-audit core documentation: Collect and check bill of lading,commercial invoice,packing list,certificate of origin,commodity inspection certificates (such as CCC certification,health certificate),etc.to ensure consistent information (such as cargo name,quantity,amount) across all documents
• Cargo pre-inspection: For goods subject to commodity inspection (such as food,cosmetics),confirm in advance whether they meet mainland inspection and quarantine standards (such as the new food nutrition label requirements introduced in 2026)

Common Problems: Mr.Luo once encountered an incorrect HS Code classification,which led to the import tax rate rising from 10% to 20%,resulting in an extra tax payment of nearly 50,000 yuan.Mr.Feng had his application returned by customs due to inconsistent information between the certificate of origin and the invoice,which delayed the delivery time after the goods arrived at the port.

Role of Zhongshen: The company has a professional classification team,which can provide accurate HS Code suggestions based on the actual situation of goods,and provide 3 rounds of free document pre-audit services.For special category goods,we will communicate with commodity inspection authorities in advance to confirm access standards,avoiding rejection due to compliance issues.

II.Port Declaration: Fast Completion of Dual Approval from Customs and Commodity Inspection

Stage Objective: Complete electronic declaration within 48 hours after the goods arrive at the port,ensure consistent manifest information and declaration information,and successfully pass the preliminary audit of customs and commodity inspection authorities.

Key Actions:

• Manifest confirmation: Synchronize and confirm cargo manifest information with the shipping company,to ensure the bill of lading number,container number,cargo weight and other information are consistent with the actual situation
• Electronic declaration: Submit declaration data through the General Administration of Customs "Single Window" system,and simultaneously submit commodity inspection declaration if required
• Tax calculation and payment: Accurately calculate customs duty,value-added tax (VAT),consumption tax (if applicable) according to the tax rate corresponding to the HS Code,and complete payment through the electronic payment system

Common Problems: After Ms.Hao’s goods arrived at the port,the declaration was rejected by customs due to inconsistency between the container size in the manifest information and the actual size,causing a delay of 3 working days.Mr.Lai overpaid 12,000 yuan due to incorrect tax calculation,and the subsequent tax refund application took nearly 2 weeks.

Role of Zhongshen: The company has established a real-time manifest synchronization mechanism with multiple shipping companies,and can obtain accurate manifest information 12 hours before the goods arrive at the port.At the same time,we have a professional tax calculation team,which can accurately calculate various taxes to avoid overpayment or underpayment,and support tax payment on behalf of customers,so that customers do not need to occupy their own funds.

III.Inspection and Release: Core Skills for Responding to Customs Inspection

Stage Objective: Successfully pass customs inspection (such as random inspection,directed inspection),timely handle problems found during inspection,and ensure fast release of goods.

Key Actions:

• Inspection preparation: Sort out cargo list and samples (if required) in advance,and arrange dedicated personnel to go to the site to cooperate with the inspection
• Problem rectification: If the goods are found to be inconsistent with the declaration information during inspection (such as quantity deviation,inconsistent product name),communicate with customers in time and rectify according to customs requirements
• Release confirmation: After passing the inspection,confirm the release status through the "Single Window" and arrange subsequent pickup

Common Problems: Manager Shi’s chemical goods were required to be rectified by customs because the packaging label did not meet the new 2026 requirements,causing a delay of 5 working days.Some enterprises have no dedicated personnel to cooperate with the inspection,leading to the inspection time extending to more than 2 days.

Role of Zhongshen: The company has on-site specialists familiar with the customs inspection process,who can arrive at the site 1 hour before the inspection and sort out all materials in advance.If problems occur,we can communicate with customs at the first time and formulate a rectification plan,shortening the average inspection time by 40%.For goods requiring rectification,we can also provide temporary storage services to avoid additional costs caused by port detention.

IV.Post-release Delivery: Realize Seamless Connection of Goods from Port to Customers

Stage Objective: Complete pickup within 24 hours after the goods are released,arrange storage or direct delivery according to customer needs,and ensure timely delivery of goods.

Key Actions:

• Pickup arrangement: Confirm pickup time with the port yard,and arrange compliant transport vehicles (such as dangerous goods transport vehicles) for pickup
• Warehouse management: If temporary storage is required,transfer the goods to Zhongshen’s bonded warehouse or ordinary warehouse near the Port of Shanghai,and provide value-added services such as sorting and labeling
• Delivery service: Arrange domestic transport (such as road,railway) according to the customer’s address,track the cargo location in real time and feed back to the customer

Common Problems: Some enterprises fail to arrange transport vehicles in advance,leading to failure to pick up goods in time after release,resulting in port detention fees (the 2026 Port of Shanghai port detention fee standard is 150 yuan per container per day).Some other enterprises face the risk of mandatory transfer by customs due to poor storage connection,leading to cargo detention at the port for more than 7 days.

Role of Zhongshen: The company has self-owned warehouses near major ports such as the Port of Shanghai and Port of Ningbo,and can provide 24-hour pickup services.At the same time,we have integrated more than 1,000 compliant transport resources across the country,and can arrange appropriate transport methods according to cargo types (such as dangerous goods,cold chain),shortening the average delivery time by 20%.
