2026 Full Process Operation Guide for Import Customs Declaration and Clearance

Import Customs Declaration and Clearance: Core Customs Link for Foreign Trade Import

In 2026 Shanghai foreign trade market,the growth of import business cannot be separated from the smooth connection of customs declaration and clearance — this is the "necessary gateway" for goods entering the domestic market from overseas,which directly affects cargo circulation speed and cost control.Many enterprises often encounter problems in operation due to complex procedures,policy changes and other issues.Today,combined with the practical experience of Zhongshen,we systematically sort out the core links of import customs declaration and clearance to help you clarify key operation points.

1.Pre-Import Preparation Stage: Lay a Solid Foundation for Customs Clearance

The core goal of this stage is to confirm commodity compliance in advance and prepare all required declaration documents to avoid subsequent delays caused by early oversights.

Key Actions:

• Confirm the HS code of imported goods and corresponding regulatory requirements: HS code is directly related to tariff rate and regulatory requirements,and needs to accurately match commodity characteristics;
• Prepare basic documents: including import contract,commercial invoice,packing list,bill of lading (or waybill),certificate of origin (to enjoy preferential tariff if required);
• Obtain regulatory documents: such as 3C Certification,import license,animal and plant quarantine permit,etc.(depending on commodity category);
• Confirm cargo transportation arrangement: Confirm arrival time with the freight forwarder and reserve customs declaration slot in advance.

Common Problems:

• Incorrect HS code classification: Some enterprises have deviated understanding of commodity material and function,leading to wrong coding,which further causes incorrect tariff calculation or missing regulatory requirements;
• Missing documents: For example,failure to apply for certificate of origin in advance leads to inability to enjoy FTA preferential tariff,increasing import cost;
• Expired regulatory documents: Some documents have validity limits,failure to renew in time leads to failure to declare.

Role of Zhongshen: The document review team led by General Manager He will intervene in advance,conduct pre-classification of commodities and issue professional opinions based on the latest 2026 customs tariff; For commodities requiring regulatory documents,remind customers to prepare 1-2 weeks in advance,and can coordinate with relevant authorities for the whole process if agency service is needed,avoiding document delay.Last year,an electronic equipment importer was required to re-declare by customs due to wrong coding,causing a 3-day delay.After Zhongshen’s intervention,all subsequent similar goods were reviewed in advance,and no such problem occurred again.

2.Declaration Stage After Cargo Arrival: Complete Customs Declaration Accurately

After cargo arrival,declaration must be completed within the specified time (generally within 14 days,overdue will incur late declaration fee).The goal of this stage is to ensure accurate declaration information and smooth passing of customs review.

Key Actions:

• Electronic declaration: Submit declaration data via China International Trade "Single Window",including commodity information,quantity,amount,HS code,etc;
• Tax calculation and payment: Calculate tariff,value-added tax,consumption tax (if required) based on declaration information,and pay via electronic payment platform;
• Customs review: Customs compares declaration data with supporting documents,and may request supplementary materials.

Common Problems:

• Inconsistent declaration information and documents: For example,invoice amount does not match the contract,or commodity description deviates from the actual goods;
• Incorrect tax calculation: Unfamiliarity with calculation rules of customs dutiable value and VAT composite taxable price leads to overpayment or underpayment;
• Late declaration fee incurred: Failure to declare on time leads to 0.5‰ late declaration fee per day for overdue,with a maximum of 0.5% of the cargo value.

Role of Zhongshen: The declaration team led by General Manager Jin is familiar with 2026 customs declaration specifications,can quickly complete "Single Window" data entry,and check the consistency between declaration information and documents in advance; For tax calculation,the team combines commodity origin,FTA policies and other information to help customers obtain preferential tariffs.For example,after the upgrade of China-Korea FTA in 2026,a cosmetic importer declared via Zhongshen and enjoyed an additional 3% tariff reduction,saving more than 20,000 RMB for a single batch of goods.In addition,the team sets declaration time reminders to avoid late declaration fees.

3.Inspection and Release Stage: Ensure Compliant Entry of Goods

After customs approval,some goods will be randomly or selectively inspected.The goal of this stage is to pass inspection smoothly and obtain customs release order.

Key Actions:

• Inspection preparation: Arrange goods according to customs requirements,ensure clear packaging marks and consistency between goods and declaration information;
• On-site inspection: Customs officers unpack containers to inspect goods,verify quantity,specification,origin,etc;
• Release: After no problem is found in inspection,customs issues release order,and goods can be picked up from the port.

Common Problems:

• Long inspection duration: Disordered cargo packaging and vague declaration information increase inspection time;
• Non-compliance in inspection: Actual commodity specifications do not match declaration,or there are undeclared accessories,leading to customs penalties;
• Increased port storage fee: Inspection delay leads to longer port stay of goods,resulting in extra storage fees.

Role of Zhongshen: The inspection coordination team led by Manager Lu will guide customers to standardize cargo packaging in advance,and arrange a dedicated person at the port to coordinate with customs inspection to ensure efficient inspection process; If non-compliance is found in inspection,the team will communicate with customs immediately,explain the situation and supplement materials.For example,a machinery parts importer missed some small accessories in declaration,after on-site coordination by Zhongshen,customs agreed to release after supplementary declaration,avoiding cargo detention.In addition,the team communicates with the port in advance and arranges container pickup time reasonably to reduce storage fees.

4.Post-Release Formalities Stage: Complete the Closed-Loop of the Whole Import Process

After cargo release,some subsequent formalities are still required.The goal of this stage is to complete cargo delivery and compliance closing.

Key Actions:

• Cargo pickup and delivery: Pick up containers from the port with release order,and transport goods to the location designated by the customer;
• Post-release customs verification: Some commodities need to accept post-release customs verification,and relevant materials shall be provided as required;
• Document archiving: Organize declaration forms,tax certificates and other materials for future reference.

Common Problems:

• Failure to cooperate with post-release verification: Failure to respond to customs verification requirements in time affects the enterprise credit rating;
• Document loss: Loss of declaration form,tax certificate and other materials affects subsequent tax refund or financial accounting (import VAT is deductible).

Role of Zhongshen: The after-service team led by Supervisor Meng follows up the whole process of cargo pickup to ensure on-time delivery; For post-release customs verification,the team prepares relevant materials in advance to assist customers to respond; All documents are organized,archived and synchronized to customers,and electronic backup is provided to avoid loss.
