# In-depth Analysis of Full Process of Import Agency Customs Declaration and Clearance and Key Node Control Strategies

## Position and Value of Import Customs Declaration and Clearance in Foreign Trade Chain

The most critical bottleneck for goods transported from overseas factories to Shanghai warehouses is not international transportation,but customs declaration and clearance.This link directly determines whether goods can be delivered on time and whether costs are controllable.Many import enterprises take customs declaration too lightly,assuming that smooth clearance can be achieved as long as documents are complete.As a result,they often encounter cargo detention at ports and incur high demurrage charges due to incorrect classification,incomplete declaration elements or missing regulatory certificates.Zhongshen has been operating in this field for 20 years,having handled more than 3,000 exception cases,and we are well aware of the hidden risks at each node.

## Stage 1: Pre-import Preparation and Document Pre-review

### Objectives and Key Actions

The core objective of this stage is to ensure cross-validation of all declaration elements is completed before the goods are shipped.Manager Deng’s team will require customers to provide basic documents including contracts,invoices,packing lists and certificates of origin,and check regulatory conditions in advance based on HS codes.Key actions include: application for pre-ruling on commodity classification,advance handling of regulatory certificates,and item-by-item confirmation of declaration elements.Last year,a machinery import enterprise was forced to return the goods after arrival at the port for failing to apply for automatic import license in advance,resulting in losses of more than CNY 800,000.

### Common Problems and Avoidance Strategies

The most common problem is that the HS code provided by customers does not match the actual goods.Zhongshen adopts a three-level review mechanism: initial review by sales representatives,re-review by customs affairs supervisors,and cross-validation of system data.In 2026,customs will conduct stricter inspection on declaration elements,especially for chemical products and electronic products.Fields such as specification and model,usage,and material must be 100% consistent with the actual goods.We recommend customers provide sample photos or technical specifications before shipment to avoid document modification after the goods arrive at the port.

## Stage 2: Goods Arrival at Port and Customs Declaration

### Objectives and Key Actions

After the goods arrive at Shanghai Port,there is a 48-hour golden declaration period.Beyond this period,demurrage charges will accumulate on a daily basis.Zhongshen’s operation process is: once the release information from the shipping company is received,pre-entry is started immediately,and the draft customs declaration form is completed before the ship berths at the port.Key actions include: confirmation of arrival report,pre-entry of draft customs declaration form,and tax and fee estimation.We maintain direct data connection with multiple on-site sections of Shanghai Customs District,and can obtain inspection risk reminders in advance.

### Exception Handling and Efficiency Optimization

In 2026,the customs implements the "two-step declaration" model,under which enterprises can first pick up goods with summary declaration,and supplement complete information within 14 days.This is a great benefit for enterprises in urgent need of goods,but the premise is that the consignor and consignee must complete the filing and have a good credit rating.Zhongshen completes qualification filing in advance for long-term cooperative customers,realizing release within 4 hours after summary declaration.For an auto parts project managed by Ms.Yuan,the clearance time was reduced from 3 days to 6 hours through this model.

## Stage 3: Customs Inspection and Tax Payment

### Inspection Types and Response Strategies

Customs inspection is divided into three types: machine inspection,manual unpacking inspection and thorough inspection.Zhongshen’s customs affairs system captures inspection instructions in real time and notifies customers to prepare explanatory materials at the first time.2026 inspection rate data shows that the inspection rate of chemical products and food remains at around 30%,and that of ordinary mechanical and electrical products is about 15%.The key is on-site cooperation.Our on-site staff will check in advance whether the shipping marks,models of the goods are consistent with the declaration information.

### Tax Calculation and Capital Planning

The import link involves customs duty,value-added tax and consumption tax,and anti-dumping duty is also applicable to some commodities.Zhongshen will issue a tax and fee estimation form before declaration to help customers arrange funds.Last year,an enterprise imported wine,and the tax payment was 40% higher than expected due to failure to calculate the anti-dumping duty,which almost broke its capital chain.Our current practice is: for commodities imported for the first time,three-level tax review must be carried out,and a 30-day customs duty guarantee insurance scheme is provided at the same time to ease the capital pressure of enterprises.

| Cargo Type | Average Inspection Rate | Common Risk Points | Zhongshen Response Plan |
| --- | --- | --- | --- |
| Chemical Raw Materials | 32% | False component declaration | Pre-submit MSDS technical specifications |
| Mechanical Equipment | 18% | Vague functional principle description | Provide product white papers and video explanations |
| Food and Agricultural Products | 35% | Delayed quarantine permit | Handle quarantine approval 30 days in advance |
| Electronic Products | 12% | Unclear solid waste attribute definition | Third-party solid waste attribute identification report |

## Stage 4: Release,Pickup and Follow-up Services

### Logistics Connection After Release

Customs release is only the first step,and subsequent processes such as commodity inspection transfer and destination inspection are also involved.Zhongshen provides full-supervised transportation services for direct delivery from the port area to the warehouse,to avoid secondary exceptions during the transportation of goods.For a medical device project managed by Mr.Wen,the goods need to be transferred to a warehouse in Jiading District for destination inspection after release.We coordinated the fleet and warehouse in advance to ensure that unloading and acceptance were completed on the day of inspection,without delaying the customer’s production for a single day.

### Document Archiving and Data Review

After each shipment is released,Zhongshen will complete the electronic archiving of documents within 3 working days and generate a customs clearance data report.This report includes: actual customs clearance time limit,inspection status,tax and fee details,and exception cause analysis.Customers can clearly see the time consumption of each link,providing decision-making basis for subsequent imports.In 2026,we launched a customer self-service query system,where enterprises can access historical customs declaration data at any time,facilitating financial audit and compliance inspection.
