# Import Customs Clearance Agency Service Provider: Full-Process Operation and Risk Avoidance

## I.Pre-Clearance Preparation Stage: Avoid Document Vulnerabilities in Advance

In the whole chain of imported goods from overseas to domestic warehouses,customs clearance is an inevitable core link.It determines whether goods can enter the country legally,how soon they can enter the market,and directly affects the capital cost of enterprises.Many enterprises try to handle customs clearance by themselves,but they often incur extra charges due to port detention,because they are not familiar with the latest 2026 Shanghai customs policies and prepare incomplete documents.The goal of this stage is to ensure all declaration materials meet the requirements and avoid subsequent delays.

### 1.1 Key Actions and Objectives

First is the collection of basic documents: import contract,invoice,packing list,bill of lading (or waybill),certificate of origin,product inspection report (such as 3C Certification,sanitary certificate,etc.).Supervisor Zhu of Zhongshen will formulate a exclusive document list in advance according to product categories (food,electronic products,mechanical equipment,etc.) to avoid missing declarations.For example,in 2026,a cosmetics enterprise once got their declaration rejected due to lack of the producing country’s hygiene standard certificate.After Supervisor Zhu reminded them to supplement the document in advance,the declaration passed at one time.

Second is pre-audit: the agency team checks the consistency of documents -- whether the product name on the contract is consistent with that on the invoice,and whether the issuing authority of the certificate of origin meets customs requirements.In 2026,Shanghai Customs upgraded the electronic verification system for certificates of origin.Zhongshen has connected with the customs system in advance and can directly verify the electronic information of documents,reducing manual review errors.

Last is policy confirmation: import tariff rates and supervision requirements for different categories change with policy adjustment (tariff of some environmental protection equipment was reduced by 5% in 2026).The policy research team of Zhongshen updates the tariff rate table every week to help enterprises confirm the optimal tariff code and avoid overpaying tariff.

### 1.2 Common Problems and Solutions

- Problem 1: Enterprises provide incomplete documents,for example,lack of Chinese label filing for food.Solution: Supervisor Zhu reminds enterprises to supplement 1-2 working days in advance.If the enterprise cannot provide it temporarily,we will assist in connecting with third-party filing institutions to shorten the time for document supplement.
- Problem 2: Incorrect tariff classification leads to overpayment of tariff.Solution: Classification consultants of Zhongshen have more than 10 years of experience and can classify accurately according to product material and function.In 2025,we helped an electronic enterprise avoid overpaying 120,000 yuan of tariff due to wrong classification.

## II.Declaration Stage After Goods Arrival at Port: Improve Declaration Approval Rate

The goal of this stage is to quickly complete customs declaration and pass the review after goods arrive at the port,so as to avoid port demurrage.In 2026,the container throughput of Shanghai Port exceeded 47 million TEUs,and declaration efficiency directly affects the turnover speed of enterprises.

### 2.1 Key Actions and Objectives

Manifest confirmation: 24 hours before goods arrive at the port,the operation team of Zhongshen confirms manifest information with the shipping company to ensure the accuracy of bill of lading number and container number.In 2026,Shanghai Port implements the "advance manifest declaration" system,and confirmation in advance can avoid declaration delay caused by manifest errors.

Electronic declaration: Submit declaration form through the single window system of General Administration of Customs.The system of Zhongshen is connected with the single window,which can automatically fill in enterprise qualification,commodity code and other information,reducing the declaration time from 2 hours to 30 minutes.

On-site inspection coordination: If the customs requires inspection,Zhongshen’s on-site specialists prepare samples and documents in advance and accompany the inspection of goods.In 2025,the goods of a mechanical equipment enterprise were inspected due to vague packaging marking.Supervisor Zhu coordinated to modify the marking on site and completed inspection and release on the same day.

### 2.2 Common Problems and Solutions

- Problem 1: Electronic declaration is rejected due to incomplete product description.Solution: The declaration team supplements product specifications,models and other information,reducing the rejection rate from the industry average of 15% to less than 5%.
- Problem 2: Inconsistency between goods and declared quantity is found during inspection.Solution: The operation team checks the packing list against the actual quantity before declaration,and assists in adjusting declaration information if there is any discrepancy,so as to avoid customs punishment.

## III.Tariff and Cost Calculation Stage: Accurately Control Cost

The goal of this stage is to accurately calculate tariff,value-added tax,consumption tax and other taxes and fees,and save unnecessary expenses.Tariff policies adjust frequently in 2026,and accurate calculation can help enterprises reduce costs.

### 3.1 Core Logic of Tax Calculation

Tariff = Duty-paid price × Tariff rate; Value-added tax = (Duty-paid price + Tariff + Consumption tax) × Value-added tax rate; Consumption tax is ad valorem or specific duty based on product categories (cosmetics,tobacco).The finance team of Zhongshen accurately calculates taxes and fees based on the latest customs duty-paid price standard to avoid calculation errors.

### 3.2 Cost Comparison of Different Payment Methods in 2026

| Payment Method | Clearing Time | Handling Fee (Yuan/Transaction) | Applicable Scenario |
| --- | --- | --- | --- |
| Customs Electronic Payment (Single Window) | Real-time clearing | 0 | Enterprises with electronic payment authorization,large tax amount |
| Bank Transfer | 1-2 working days | 50-100 | Enterprises without electronic payment authorization,small tax amount |
| Payment via Agency | Real-time clearing | 200-300 | Enterprises requiring quick release,or without foreign exchange payment authority |

Zhongshen recommends the optimal payment method according to the actual situation of enterprises.In 2026,a food enterprise chose electronic payment and saved about 2,000 yuan in handling fees every year.If enterprises meet the requirements of tariff reduction policies (such as imported scientific research equipment),we will assist in applying for reduction.In 2025,we helped a technology enterprise get a tariff reduction of 350,000 yuan.

## IV.Goods Release and Follow-up Stage: Ensure Smooth Delivery

The goal of this stage is to complete release,arrange domestic transportation and process subsequent document filing.Under Shanghai’s "port-navigation linkage" policy in 2026,the connection efficiency of domestic transportation directly affects the delivery cycle of enterprises.

### 4.1 Key Actions and Objectives

Release confirmation: After the customs review is passed,Zhongshen will notify the enterprise or warehouse to pick up goods immediately upon receiving the release notice.In 2026,Shanghai Port launched the "release first,inspect later" pilot.Zhongshen confirms in advance whether the goods are within the pilot scope to help enterprises pick up goods earlier.

Domestic transportation arrangement: We cooperate with a number of logistics enterprises in Shanghai to provide door-to-door pickup,warehousing and distribution services,and select appropriate transportation methods according to product categories (fragile goods,dangerous goods).In 2025,we helped a chemical enterprise transport dangerous goods,the whole process complied with safety specifications and no accident occurred.

Document filing: All documents (declaration form,tariff certificate,inspection record,etc.) are sorted and filed,and both electronic and paper versions are provided for enterprises’ financial accounting and audit.

### 4.2 Common Problems and Solutions

- Problem 1: Enterprises cannot pick up goods in time after release,resulting in warehouse storage demurrage.Solution: Our warehousing team provides temporary warehousing with a maximum of 3 days free storage,helping enterprises gain time for picking up goods.
- Problem 2: Customs clearance documents cannot be found during audit.Solution: We use an electronic file management system,stored by enterprise and year,and enterprises can query at any time.In 2026,an enterprise retrieved nearly 3 years of documents within 30 minutes during audit.

From document preparation to goods delivery,import customs clearance has many links and policies change rapidly.Self-operation by enterprises requires a lot of human input,and it is easy to cause delays or fines due to negligence.Zhongshen has been deeply engaged in the industry for 20 years,with mature processes and professional teams for each link -- pre-audit avoids document vulnerabilities,electronic declaration improves approval rate,and tax calculation controls cost.Ms.Ni,the person in charge of a foreign trade enterprise,after choosing Zhongshen in 2025,the customs clearance time was shortened from 7 days to 3 days,saving about 150,000 yuan of port demurrage and tariff every year.
