Complete Breakdown of Full Process of Overseas Import Cargo Customs Clearance and Key Notes

Full Process Breakdown and Practical Guide for Overseas Import Cargo Customs Clearance

For overseas imported goods from the port of departure to the domestic destination,customs clearance is the core node connecting international transportation and domestic distribution -- whether the goods can be released quickly after arrival,whether additional fees are incurred,and whether compliance meets standards all depend on the operation of the customs clearance link.Although the import customs clearance policy of Shanghai Port has been optimized in 2026,process details still require accurate control.It is not uncommon for many enterprises to have cargo delays of more than 3 days due to unfamiliarity with new regulations or operational errors.This article systematically sorts out the core stages and precautions of the full customs clearance process based on Zhongshen’s more than 20 years of practical experience.

I.Pre-Import Preparation Stage (Key: Compliance in Advance,Avoid Passivity After Arrival)

1.1 Stage Objective

Ensure that cargo information,qualification documents fully match the policies of the importing country,and avoid declaration rejection caused by incomplete or non-compliant materials in advance.

1.2 Key Actions

• Confirm cargo HS Code and supervision conditions: Must correspond to the latest 2026 tariff schedule.Some commodities (such as electronic products,food) need to apply for 3C Certification,sanitary quarantine permission in advance
• Prepare import qualification documents: Including import and export operation right (you can entrust an agent if you have no qualification),contract,invoice,packing list,bill of lading (or waybill),certificate of origin,etc.
• Dock cargo details with Zhongshen: Supervisor Fu will check whether the cargo weight,volume and declared value are consistent with the actual situation,to avoid the risk of under-declaration or over-declaration

1.3 Common Issues

• Incorrect HS Code classification: The codes of some chemical products and medical devices have been adjusted in 2026.Wrong classification may lead to a tax rate difference of more than 10%,and also trigger customs inspection
• Missing qualification documents: For example,food products without completing sanitary quarantine approval in advance cannot be declared after cargo arrival,and can only be temporarily stored in the supervised warehouse,resulting in storage fees

1.4 The Role of Zhongshen

Supervisor Fu will arrange a dedicated person to check the latest 2026 tariff schedule and supervision policies.For commodities that require pre-approval (such as cosmetics filing),we will assist customers to complete material submission 3-5 working days in advance; if the customer does not have import and export operation right,we can provide agency qualification to avoid customs clearance delay caused by qualification issues.

II.Cargo Arrival and Declaration Stage (Key: Accurate Data,Rapid System Entry)

2.1 Stage Objective

Complete electronic declaration within 24 hours after cargo arrival,ensure system data is consistent with paper documents,and pass the preliminary customs review.

2.2 Key Actions

• Enter information into the customs declaration system: Accurately enter the information of contract,invoice,packing list into the China International Trade Single Window
• Submit tariff and value-added tax declaration: Calculate taxes according to the tax rate corresponding to the HS Code,and submit after confirmation
• Follow up the system review status: Respond to the system’s requirement for supplementary materials in a timely manner

2.3 Common Issues

• Inconsistent declaration data: For example,the invoice amount does not match the contract,or the difference between the packing list weight and the bill of lading weight exceeds 5%,which will be rejected by the system for re-declaration
• Incorrect tax calculation: The tax rates of some free trade agreements have been adjusted in 2026.Failure to update the latest rate may lead to overpayment or underpayment of taxes,triggering subsequent verification

2.4 The Role of Zhongshen

Manager Hua’s team is familiar with the operation process of the Single Window,and the average declaration entry time is no more than 1 hour; for goods under free trade agreements,we will check the validity of the certificate of origin in advance to help customers enjoy preferential tax rates (for example,the RCEP agreement tax rate is 2-5% lower than the most-favored-nation tax rate).We also follow up the review status in real time,and the response time for supplementary materials is no more than 2 hours.

III.Inspection and Release Stage (Key: Cooperate with Inspection,Rapid Customs Clearance)

3.1 Stage Objective

If inspection is triggered,cooperate with customs to complete cargo verification; if no inspection is triggered,release directly and connect to domestic transportation.

3.2 Key Actions

• Confirm inspection type: Customs may conduct manual inspection,machine inspection or unpacking inspection,and you need to prepare the cargo list in advance for customs verification
• Cooperate with on-site inspection: Arrange a dedicated person to be present,assist customs in unpacking and sampling,and ensure that cargo information is consistent with the declaration
• Release after tax payment: After taxes are paid,the customs system releases the cargo,and you can arrange pickup

3.3 Common Issues

• Cargo found inconsistent with declaration during inspection: For example,declared as general trade cargo,but actually contains prohibited imported used equipment,which will be detained by customs
• Inspection delay: Failure to prepare cargo labels in advance (such as no Chinese label pasted) leads to inspection time extended by more than 1 day

3.4 The Role of Zhongshen

General Ke’s team has rich experience in customs inspection coordination,we will inform customers of inspection precautions in advance (such as food needs to provide Chinese labels,electronic products need to paste 3C marks); if inspection is triggered,we arrange a dedicated person to accompany the whole process,and the average inspection response time is no more than 30 minutes,helping customers reduce inspection delay.

IV.Subsequent Settlement and Filing Stage (Key: Clear Reconciliation,Compliant Retention)

4.1 Stage Objective

Complete customs clearance fee settlement,retain all materials for subsequent verification (such as customs audit,tax refund).

4.2 Key Actions

• Check customs clearance fees: Including tariff,value-added tax,agency fee,storage fee (if any),ensure each fee has a clear breakdown
• File all documents: Retain declaration forms,inspection records,tax certificates for at least 3 years (required by customs audit)

4.3 Common Issues

• Unclear fee breakdown: Some agents do not provide tax certificates,leading to enterprises cannot record the expenses or have no basis for subsequent verification
• Incomplete data retention: Missing data within 3 years may be fined by customs

4.4 The Role of Zhongshen

General Yang’s team will provide a detailed fee list,each tax is attached with the tax payment certificate printed by customs; all customs clearance documents are archived electronically and backed up in paper,customers can retrieve them at any time to meet the requirements of customs audit.
