### 1.Pre-Clearance Preparation Stage: Complete Documents as the Foundation of Efficient Customs Clearance

**Stage Objective**: Ensure all customs clearance documents are complete and compliant,avoiding delays caused by missing items during declaration.

**Key Actions**:

- Verify core cargo information: product name,HS code,quantity,weight,cargo value and trade terms
- Prepare necessary customs clearance documents (list see below)
- Confirm whether the cargo requires commodity inspection,3C certification or tariff preferences (such as certificate of origin)

**Common Problems**:

- Incorrect HS code classification: For example,a new type of electronic chip is mistakenly classified as a common component,resulting in a tax rate increase of more than 10%
- Missing documents: The certificate of origin is not handled in advance,so the tariff preferences under the free trade agreement cannot be enjoyed
- Expired 3C certification: Medical devices requiring 3C certification have not updated their certificates,resulting in cargo being detained

**Role of Zhongshen**: Manager Lu will verify the cargo information with customers in advance,and accurately classify HS codes based on 20 years of industry experience; if the cargo requires commodity inspection or 3C certification,Manager Lu will assist in connecting with the Shanghai Commodity Inspection Department and prepare test reports in advance,saving an average of 3 working days compared to customers handling it by themselves; for goods under free trade agreements,Manager Lu will remind customers to apply for the certificate of origin,helping customers save 5%-15% of tariffs.

### 2.Cargo Arrival Declaration Stage: Declare on Time to Avoid Delays

**Stage Objective**: Complete electronic declaration within 24 hours after the cargo arrives at the port,submit paper documents and pay taxes and fees.

**Key Actions**:

- Complete electronic declaration through the Single Window of the General Administration of Customs
- Submit paper documents to the customs window of Shanghai Pudong/Hongqiao Airport
- Pay tariffs,value-added tax and consumption tax (if applicable)

**Common Problems**:

- Inconsistent declaration data with actual situation: Weight error exceeds 5%,resulting in customs inspection control
- Incorrect tax calculation: Failure to update the exchange rate in time leads to overpayment or underpayment of taxes and fees
- Delayed declaration: Declaration made more than 24 hours after the cargo arrives,resulting in declaration delay fines

**Role of Zhongshen**: Mr.Mo is responsible for electronic declaration,and synchronizes the new declaration fields for electronic components added by the customs in 2026 in real time to ensure accurate data; tax payment supports online banking and third-party payment,no need for customers to queue; if there is a slight data inconsistency,Mr.Mo will contact the customer to adjust immediately without affecting the declaration progress; at the same time,remind customers to declare on time to avoid declaration delay fines (declaration delay fines are charged at 0.05% per day,and the cargo will be sold after 30 days of overdue).

### 3.Inspection and Release Stage: Accompany the Whole Process to Reduce Inspection Risks

**Stage Objective**: Pass customs inspection smoothly and obtain the release order to arrange delivery.

**Key Actions**:

- Cooperate with customs random inspection or controlled inspection
- Open the box to check whether the cargo is consistent with the declaration information
- Collect the release order after confirming no problems

**Common Problems**:

- Inconsistent cargo and declaration information: Incorrect product name or quantity difference,resulting in prolonged inspection time
- Missing auxiliary documents: No product manual,customs cannot confirm the cargo attributes
- Too long inspection time: Affects subsequent delivery and generates extra storage costs

**Role of Zhongshen**: Manager Zhan will prepare auxiliary inspection documents (product manuals,third-party test reports) in advance and accompany the whole process on site; if there are minor problems (such as unclear packaging labels),Manager Zhan will coordinate on-site rapid processing,with an average inspection time 4 hours shorter than the industry average; since 2026,the inspection pass rate of cargo entrusted by Zhongshen has reached 97%,and the release time has been shortened by 60%.

### 4.Subsequent Settlement and Archiving Stage: Transparent Settlement + Long-term Archiving

**Stage Objective**: Complete fee settlement and archive all documents for subsequent inquiries.

**Key Actions**:

- Settle all fees including customs clearance service fees,tariffs,storage fees,etc.
- Archive customs clearance documents with electronic and paper dual backups (stored for 5 years)

**Common Problems**:

- Unclear fee details: Hidden fees lead to customer cost overrun
- Missing documents: Cannot be provided when needed later,affecting tax refund or audit

**Role of Zhongshen**: Manager Yang will issue a detailed fee list,indicating the source and amount of each fee,with no hidden fees; documents are archived with online system + paper file dual backups,and customers can query historical customs clearance records at any time; since 2026,customer satisfaction with the fee transparency of Zhongshen has reached 99%.
