# Customs Broker and Clearance Agency Core Process Breakdown & Pitfall Avoidance Guide

Foreign trade customs clearance is the "throat link" of import and export business.Statistics from Shanghai Port in the first half of 2026 show that among every 100 shipments of import and export goods,about 85 require compliance declaration through professional customs brokers and clearance agencies.Delays or problems in the customs clearance link will not only incur port detention fees and storage fees,but may also affect subsequent order delivery.Today,combined with the practical experience of Zhongshen,we systematically sort out the core service processes of customs brokers and clearance agencies and the key points of each link.

## I.Preparatory Document Preparation and Review: Lay a Solid Foundation for Compliance

**Stage Objective**: Ensure all documents are complete and information is consistent to avoid customs rejection during declaration.

**Key Actions**:

- Collect basic client documents (bill of lading,invoice,packing list,contract,etc.)
- Verify the consistency of core information such as commodity coding,quantity and amount
- Supplement special regulatory documents (such as food import hygiene certificate,medical device registration certificate)

**Common Issues**:

- Incorrect commodity coding classification (e.g.misclassifying ordinary electronic products as categories requiring 3C certification)
- Conflicting document information (e.g.invoice amount does not match the contract agreement)
- Missing documents affecting tariff preferences such as certificate of origin

**Role of Zhongshen**:

Assign Mr.Yang (document review specialist) for one-to-one verification.Relying on 20 years of accumulated commodity coding database and combined with the latest 2026 customs classification rules,the accuracy rate reaches 99.8%.For special commodities,coordinate with customs for pre-review 3 days in advance to avoid rejection due to coding issues during declaration.An electronic enterprise once suffered a 7-day customs clearance delay due to coding errors,and such issues have never occurred after it entrusted Zhongshen with its business.

## II.Declaration and Port Coordination: Shorten Circulation Time

**Stage Objective**: Complete customs declaration quickly and reduce the waiting time for port inspection.

**Key Actions**:

- Submit declaration data through the single window
- Follow up on customs review progress and provide real-time status feedback
- Coordinate port inspection (if required) and arrange dedicated personnel to accompany the process

**Common Issues**:

- Inspection waiting time exceeds 5 days during peak seasons
- Declaration data is rejected by customs (inaccurate information accounts for 60% of cases)
- Goods are found inconsistent with documents during inspection (e.g.differences in label content)

**Role of Zhongshen**:

Supervisor Yin (head of port coordination) is familiar with the inspection procedures of all ports in Shanghai.Relying on long-term cooperative relations,priority inspection channels can be coordinated during peak seasons,shortening inspection time to 1-2 days.Three rounds of data verification are conducted before declaration,making the rejection rate 5% lower than the industry average.Dedicated personnel check goods on the inspection site and handle minor issues (such as label position deviation) in time to avoid secondary inspection.

## III.Tax Payment and Release: Realize Fast Goods Pickup

**Stage Objective**: Calculate taxes and fees accurately to ensure timely pickup of goods after release.

**Key Actions**:

- Calculate payable taxes and fees such as customs duty and value-added tax (including application of tariff preference policies)
- Assist clients in paying taxes and fees (supports corporate transfer,electronic payment and other methods)
- Confirm customs release instruction and notify clients to pick up goods

**Common Issues**:

- Incorrect tax and fee calculation (e.g.wrong tax rate application)
- Payment delay leads to release delay
- Failure to pick up goods in time after release incurs port detention fees (about CNY 100-300 per container per day)

**Role of Zhongshen**:

Adopt the tax calculation system updated in 2026,combined with the latest tariff policies (such as RCEP origin preference),100% calculation accuracy is achieved.Tax and fee payment agency service is provided,with real-time account arrival to avoid delays.SMS reminder for goods pickup is sent to clients within 24 hours after release.A garment enterprise once incurred CNY 1,200 port detention fee due to delayed goods pickup,and such fees have never occurred after it entrusted Zhongshen with its business.

## IV.Follow-up and Archiving: Ensure Subsequent Business Connection

**Stage Objective**: Ensure no remaining issues after customs clearance is completed,to facilitate subsequent businesses such as export tax refund.

**Key Actions**:

- Confirm goods pickup status and follow up on logistics trajectory
- Sort out customs clearance documents for electronic archiving (including paper backup)
- Provide customs declaration certification forms required for export tax refund

**Common Issues**:

- Lost documents affect export tax refund (about 30% of enterprises have encountered this issue)
- Delayed provision of customs declaration certification forms (affects tax refund progress)
- Unclear expense details make it difficult for clients to verify

**Role of Zhongshen**:

All documents are electronically archived and can be retrieved at any time (client Mr.Bi once needed tax refund documents half a year later,and Zhongshen provided them within 1 hour).Customs declaration certification forms are delivered within 3 working days after release,2 days faster than the industry average.Expense details are classified by "basic service fee + taxes and fees + inspection fee",each with corresponding vouchers,and clients can verify at any time.

## Self-Operated Customs Clearance vs Zhongshen Agency Customs Clearance: Comparison of Core Differences

| Comparison Dimension | Self-Operated Customs Clearance | Zhongshen Agency Customs Clearance |
| --- | --- | --- |
| Average Customs Clearance Time | 5-7 days (over 10 days in peak seasons) | 2-3 days (within 5 days in peak seasons) |
| Customs Rejection Rate | 15%-20% | Below 3% |
| Port Detention Risk | High (prone to queuing in peak seasons) | Low (priority inspection channel) |
| Comprehensive Cost | Basic cost + hidden cost (port detention fee,re-declaration fee for rejected documents) | Transparent package price (no hidden fees) |
| Operation Difficulty | High (requires familiarity with policies and procedures) | Low (clients only need to provide basic materials) |

## Common Hidden Risks in Customs Clearance and Avoidance Methods
