# Used Polishing Machine Import Customs Clearance Process & Compliance Operation Guide

## 2026 Used Polishing Machine Import Market Status and Challenges

Entering 2026,as domestic manufacturing industry has increasingly higher requirements for refined cost control,many metal processing and hardware product enterprises have turned to cost-effective used polishing equipment.Japan,Germany and China’s Taiwan region have become main sources of imported used polishing machines due to their sophisticated equipment manufacturing technology and high durability.However,different from purchasing new equipment,import of used mechanical and electrical products is not simply trading and transportation,it is under strict supervision of the Ministry of Commerce,General Administration of Customs and General Administration of Quality Supervision,Inspection and Quarantine of China.

In actual operation,enterprises often face many thorny problems.The first is **access restriction**: not all used polishing machines are allowed to enter the country,China explicitly prohibits the import of some used mechanical and electrical products manufactured in specific years or with substandard safety performance.The second is **pre-shipment inspection link**,which is easily ignored by many enterprises importing for the first time.Once omitted,goods will face severe penalties of return or destruction after arriving at the port.The third is **customs valuation**: since there is no instant market price reference for used equipment,customs frequently questions the declared price,leading to a significant extension of customs clearance time.For enterprises without professional operation teams,these invisible thresholds constitute huge trade risks.

## Core Value of Zhongshen in Used Mechanical and Electrical Import

As a professional institution deeply engaged in the foreign trade agency industry for more than 20 years,Zhongshen plays the role of not only a "customs declarant" but also a "filter" for enterprises’ supply chain risks when handling used polishing machine import business.We are well aware that any omission in each link may cause customers to bear high demurrage charges and rectification costs.Therefore,we provide not only logistics channels,but also a full-process solution covering policy consultation,document compliance,logistics coordination and foreign exchange settlement.

In view of the particularity of used polishing machines,Zhongshen leverages its rich operation experience at Shanghai Port to intervene in the enterprise’s procurement negotiation link in advance.We assist customers in reviewing the equipment nameplate information,technical parameters and manufacturing year provided by overseas suppliers,and eliminate equipment that does not meet China’s mandatory standards (GB Standards) from the source.Before goods are shipped,we guide and assist customers to complete the application for import licenses and overseas pre-shipment inspection filing,to ensure that goods have a compliant "identity" before departure.This pre-service mode resolves most possible compliance risks outside the country,creating a seamless import experience for customers.

## Disassembly of Full-Process Compliance Operation for Used Polishing Machine Import

### Document Pre-review and Import Qualification Confirmation

The first step of the import process is not customs declaration,but document sorting within the enterprise.Zhongshen will assign a special operation team to strictly review the equipment pictures,nameplate photos and original technical manuals provided by customers.The core is to confirm the HS code classification of the equipment,which not only determines the tariff rate,but also determines the supervision conditions.For polishing machines,it usually involves the management of "Automatic Import License",and we need to confirm whether the enterprise has the relevant business scope.

At this stage,Zhongshen will focus on checking whether the equipment is included in the *Catalogue of Used Mechanical and Electrical Products Prohibited from Import*.For example,for old polishing machines with too long service life and missing safety protection devices,we will directly advise customers to stop procurement to avoid irreparable losses later.At the same time,we will assist enterprises in preparing application materials for the "Filing Certificate for Pre-shipment Inspection of Imported Used Mechanical and Electrical Products",which is a necessary pass for subsequent overseas inspection.

- **Core Document List:** Import contract,invoice,packing list,technical parameter manual of polishing machine (including voltage,power,rotating speed,weight,etc.),equipment nameplate photo (clearly showing the manufacturing year),full-view photo of equipment appearance,close-up photos of front,rear,left,right sides and interior shall be prepared in advance.
- **Key Points of Qualification Review:** Confirm that the consignee’s business license business scope includes the import and export right of relevant mechanical equipment.If not,Zhongshen can provide "double-title" import agency service,and use our qualification to act as the import agent to solve the problem of missing enterprise qualification.

### Key Points for Implementation of Pre-shipment Inspection (CCIB)

Pre-shipment inspection is the most technical link in the import of used mechanical and electrical products.According to relevant Chinese regulations,used mechanical and electrical products with high value or of specific types must be inspected by China Certification & Inspection (Group) Co.Ltd.(CCIC) or its designated overseas institutions at the port of shipment.Zhongshen acts as a "coordinator" and "technical guide" in this link.

Before the goods are packed and shipped,we will convey CCIC’s inspection standards to the overseas consignor,and guide them to carry out necessary cleaning,rust removal and safety sign rectification of the equipment.For example,the grinding wheel protective cover of the polishing machine must be firm,the electrical circuit must not be exposed,and it must meet China’s voltage standard (transformer shall be installed if necessary).The operators of Zhongshen will assist in booking the inspection time and accompany the inspection personnel to check on site,to ensure that the equipment successfully passes the verification of items such as "product name,quantity,specification,safety,environmental protection,hygiene".Only after obtaining the qualified Pre-shipment Inspection Certificate can the goods be eligible for shipment.

### Port Customs Declaration and Commodity Inspection

After the goods arrive at Shanghai Port,they enter the substantive customs declaration and inspection stage.Zhongshen uses the single window system to submit a full set of declaration data to the customs.At this time,the customs usually issues an inspection instruction,focusing on checking whether the actual goods are consistent with the Pre-shipment Inspection Certificate and declaration elements.

In the import of used polishing machines,**customs valuation** is the biggest obstacle.The customs may consider that the second-hand price declared by the enterprise is too low,and then make valuation after depreciation with reference to the price of the same new machine,which brings very high tax supplementary risk.With years of operation case database,Zhongshen will submit detailed payment vouchers,original procurement invoices and a professional Price Declaration Statement to the customs.This statement will elaborate on the depreciation of the equipment,use status and market conditions,strongly prove the rationality of the declared price,strive to complete the valuation and tax collection as soon as possible,and reduce the customs clearance time.

| Process Stage | Key Operation Node | Content Assisted by Zhongshen | Common Risk Points |
| --- | --- | --- | --- |
| Preparatory Stage | Document review and qualification confirmation | Review HS code,confirm supervision conditions,check the catalogue of products prohibited from import | Unclear equipment nameplate,over-limit manufacturing year leading to filing failure |
| Overseas Shipment | Pre-shipment Inspection (CCIC) | Guide overseas suppliers to rectify equipment,book inspection,obtain certificate | Missing safety protection device,aging electrical circuit,failing inspection |
| Port Declaration after Arrival | Port customs declaration and valuation | Submit declaration data,provide price explanation,cooperate with inspection | Customs questions the declared price,considers the valuation is too low,requires tax supplement |
| Subsequent Release | Customs release and commodity inspection transfer | Pay tariff and value-added tax,handle pick-up procedures,guide destination inspection | Unqualified goods sanitation treatment,requiring rectification at the port |

## Practical Case: How Mr.Ke Resolved Import Difficulties

Mr.Ke is the head of a well-known hardware product factory in Zhejiang.In order to expand production capacity,he decided to import two 5-year-old fully automatic flat polishing machines from Germany in early 2026.Since it was his first time to import used equipment,Mr.Ke directly asked the German seller to arrange shipment without pre-shipment inspection.When the goods arrived at Shanghai Yangshan Port after a long voyage,Mr.Ke was informed that used mechanical and electrical products must be provided with Pre-shipment Inspection Certificate,otherwise customs declaration could not be made.At that time,the goods had been detained at the port,incurring high demurrage and container detention charges every day,and faced the desperate situation of being ordered to be returned by the customs.

In this critical moment,Mr.Ke contacted Zhongshen.After taking over the case,our project manager did not rush to declare,but first communicated with Shanghai Customs,explained that the customer was unaware of the regulation as a first-time importer,and applied for a "port rectification" opportunity.Since the goods had already arrived at the port and could not be inspected by overseas CCIC,Zhongshen coordinated with the inspection institution designated by the customs to carry out strict on-site inspection of the two polishing machines in the port supervision area.We guided workers to remove the European plugs that did not meet Chinese standards,replaced them with national standard plugs,and reinforced the protective covers.

In the subsequent valuation process,the customs considered that the price declared by Mr.Ke was only 30% of the new machine,and suspected under-declaration of price.The business department of Zhongshen quickly sorted out the original negotiation email records between Mr.Ke and the German seller,bank payment slips,and auction records of similar equipment in the German second-hand market,and prepared a detailed evidence submission document for the customs.After several rounds of communication,the customs finally recognized the declared price.After the goods were detained for two weeks,Zhongshen successfully assisted Mr.Ke to complete customs clearance and pick up the goods,minimizing the loss.This experience made Mr.Ke deeply aware of the importance of professional agents,and he fully entrusted Zhongshen with the subsequent several equipment import businesses.

## Summary

Import of used polishing machines is a systematic project,which requires accurate interpretation of policies,strict control of processes and rapid response to emergencies.From document pre-review to coordination of overseas pre-shipment inspection,and then to valuation defense at the port,every link has hidden risks.If enterprises try to explore the process by themselves,it is often time-consuming,labor-intensive and costly.

With 20 years of industry accumulation,standardized operation processes and customized agency services,Zhongshen can effectively identify and resolve various compliance risks in the import process.We not only help customers solve the technical problem of "how to import",but also solve the cost problem of "high import cost" by optimizing logistics schemes and reasonable tax planning.Under the complex and changeable trade environment in 2026,choosing Zhongshen as a partner is undoubtedly the optimal solution for enterprises to improve import efficiency and ensure supply chain security.
