# Detailed Explanation of Core Services and Operation Procedures of Import Customs Brokerage

## Background and Challenges of European Precision Equipment Import in 2026

In 2026,China’s manufacturing industry’s dependence on high-end automated production lines continues to rise,and a large number of enterprises choose to introduce used precision equipment from European countries such as Germany and Switzerland to reduce costs.However,the import threshold for such products has increased significantly in 2026.Customs has become increasingly strict in pre-shipment inspection of old mechanical and electrical products,hazardous chemical composition testing,and energy efficiency label review.Many enterprises often cause cargo detention at ports due to unfamiliarity with the acquisition process of the Pre-shipment Inspection Certificate or deviation in understanding of HS code classification when operating on their own,resulting in high detention and storage fees.

In addition,the 2026 revised Law on Prevention and Control of Solid Waste Pollution and the adjustment of relevant import license catalogs make the risk of old equipment being identified as solid waste objectively exist.Once the attribute of the goods is not clearly defined,enterprises will not only face the risk of return,but also have their credit rating downgraded.In this context,professional import customs brokerage services are no longer a simple "errand" role,but an indispensable compliance firewall in the enterprise supply chain.

## Core Value of Zhongshen Import Agency Services

Zhongshen has been deeply engaged in the foreign trade agency field for more than 20 years.In response to the complex import environment,it has built a set of service system with "compliance pre-positioning" as the core.We not only submit data to the customs for customers,but also intervene in the review before the goods are shipped.Through pre-classification and risk assessment,we eliminate possible customs clearance blockages in the bud.For the import of European precision equipment,Zhongshen’s core role is to make use of in-depth interpretation of policies,coordinate overseas inspection institutions and domestic regulatory authorities,and ensure the integrity and logical consistency of the document chain,so as to greatly shorten the customs clearance cycle and reduce hidden costs.

## Step-by-Step Breakdown of Full-Process Agency Services

### Document Pre-review and Compliance Confirmation

Before the goods are shipped,the project manager of Zhongshen will start the document pre-review procedure.This is the most critical step in the entire import process.Manager Qiao pointed out that many customs clearance failure cases stem from logical conflicts between documents.For example,the currency value on the invoice is inconsistent with the contract terms,or the manufacturing year on the equipment nameplate is inconsistent with the declaration elements.At this stage,we need to focus on processing the following core documents:

- Import License: For restricted import old mechanical and electrical products,assist enterprises to apply for Automatic Import License or Special Mechanical and Electrical Product License from the Ministry of Commerce.
- Pre-shipment Inspection Certificate (PSI): Coordinate inspection institutions recognized by China to carry out inspection in the country of dispatch to ensure that the equipment meets safety,hygiene and environmental protection requirements.
- Certificate of Origin: Verify the origin criteria to determine the applicability of preferential tariff treatment.
- Chinese Instruction Manual: Review whether the translation of equipment technical parameters is accurate and whether it meets domestic labeling specifications.

Zhongshen will compare document information through the internal system,correct logical errors in declaration elements,and ensure that "documents match goods" is theoretically verified before shipment.

### International Transportation and Port Declaration

After the goods leave the port,Zhongshen takes advantage of long-term contracts with major shipping companies to arrange sea or air transportation to Shanghai Port.Before the goods arrive at the port,we have completed the entry of declaration data in the single window.The 2026 customs system has fully realized intelligent risk control,and the system will automatically capture risk points in the declaration data.Our operation team will adjust the declaration strategy according to the latest risk control parameters.For example,old machine tools with hydraulic systems may trigger hazardous chemical attribute verification.We will prepare MSDS reports and non-hazardous certificates in advance,and take the initiative to explain the situation to the customs to avoid customs clearance delays caused by the system automatically transferring to manual inspection.

### Commodity Inspection and Subsequent Release

For old mechanical and electrical products,statutory inspection is a necessary link.When the customs issues an inspection instruction,Zhongshen’s customs affairs personnel will rush to the inspection site as soon as possible to cooperate with customs officers in unpacking inspection.In this link,the appearance of the equipment,nameplate information,and the safety of electrical circuits are the key points of inspection.Manager Qiao emphasized that on-site communication skills are very important.We need to accurately explain the working principle,refurbishment degree and rectification plan of the equipment to the customs officers.If minor label missing or inadequate sanitary cleaning is found during inspection,we will immediately arrange rectification in the port supervision area,and strive to pass the inspection and release at one time,so as to avoid the goods being handed over to the Customs Anti-smuggling Department for handling.

To more intuitively show the operational differences between different import methods,the following table compares the differences between self-handled import by enterprises and import agency by Zhongshen in key links:

| Comparison Dimension | Self-handled Import by Enterprises | Import Agency by Zhongshen |
| --- | --- | --- |
| Document Preparation | Rely on internal procurement or administrative staff of the enterprise,key regulatory certificates are easily missed. | Professional pre-review team checks item by item to ensure that licenses,PSI and other documents are complete and valid. |
| Customs Clearance Efficiency | Unfamiliar with customs system operation,repeated modifications are required when encountering returned orders,average time consumption is long. | Familiar with system logic,high one-time declaration pass rate,customs clearance speed is significantly improved. |
| Inspection Response | Lack of on-site communication experience,often at a loss when encountering problems,rectification efficiency is low. | Customs affairs experts accompany on site,can quickly explain and provide rectification plans,reduce inspection risks. |
| Cost Control | High hidden costs caused by port detention and fines,and tax cannot be optimized. | Through reasonable classification and compliance planning,additional expenses are reduced,comprehensive cost is lower. |

## Practical Case: Avoiding Return Risk of Old Mechanical and Electrical Products Import

In early 2026,an auto parts manufacturing enterprise in Shanghai imported a 5-year-old machining center from Germany.Due to internal personnel changes of the enterprise,the original technical drawings of the equipment were omitted during handover,resulting in failure to accurately provide key declaration elements such as the number of shafts of the equipment and the model of the control system when declaring customs at the port.The customs system determined that the declaration elements were vague and issued a thorough inspection instruction.

If handled by the enterprise itself,it is very likely that the goods will be identified as prohibited import goods due to failure to provide complete technical materials,and face the fate of return or even destruction.After Zhongshen intervened,Manager Qiao immediately contacted the German shipper,and remotely guided the other party to find the hidden technical document bag in the equipment packing box through video connection,and obtained the factory configuration sheet of the equipment.After obtaining the key information,we quickly submitted the situation description and supplementary materials to the customs,explaining the processing capacity and purpose of the equipment in detail.Finally,the customs approved our supplementary declaration,and the goods were released smoothly.This case fully shows that professional agency services can recover huge economic losses for enterprises through experience accumulation and resource integration at critical moments.

## Summary

Import customs brokerage agencies play the role of "compliance operator" in the 2026 foreign trade ecosystem.From refined pre-review of documents to professional response to port inspection,every link requires deep industry accumulation.Zhongshen helps customers effectively avoid complex policy risks through standardized operation procedures and customized solutions.For enterprises,choosing a partner with full-process operation capability like Zhongshen can not only improve import efficiency,but also ensure steady business growth in an increasingly strict regulatory environment.
