# Full Analysis of Customs Clearance Difficulties and Compliance Operation Procedures for Imported Eco-friendly Cleaning Agents

## Background and Supervision Difficulties of Imported Eco-friendly Cleaning Agents

Entering 2026,as domestic requirements for environmental protection and work safety continue to improve,supervision standards for imported eco-friendly cleaning agents show a trend of refinement and strictness.Many enterprises mistakenly assume that the label of "eco-friendly" equals low risk,which is not the case.Such products usually fall into the category of chemical products,and involve complex component definition in the actual import process.Even if products are promoted with the eco-friendly concept,they may still contain flammable,corrosive or sensitizing chemical components internally,which directly increases the difficulty of HS Code classification and hazardous characteristic identification.

At present,the inspection intensity for chemical products at Shanghai Port and other major ports has increased significantly.Common difficulties faced by imported eco-friendly cleaning agents are mainly concentrated in three aspects: first,the authenticity of component declaration and the consistency review of Material Safety Data Sheet (MSDS); second,whether the Chinese label complies with the GB 30000 series standards and the latest label specifications implemented in 2026; third,on-site identification of hazardous attributes during port inspection.If a product is identified as a hazardous chemical but not declared according to the hazardous chemical procedure,the enterprise will face return shipment,administrative penalties and huge costs caused by cargo detention.Therefore,when importing such products,enterprises urgently need professional agency services to cope with these compliance challenges.

## Core Role of Zhongshen in Import Agency

Zhongshen has been deeply engaged in the foreign trade import and export agency industry for more than 20 years,and has accumulated rich practical experience in the field of chemical import.For the agency business of imported eco-friendly cleaning agents,we not only provide logistics and transportation services,but also act as the "gatekeeper" for enterprises’ compliant import.Our core role is to use professional knowledge to accurately predict the risk attributes of products before shipment,so as to formulate the optimal import plan.

Through long-term positive interaction with customs,commodity inspection bureaus and professional testing institutions,we can grasp the latest 2026 supervision dynamics at the first time.For imported eco-friendly cleaning agents,the operation team of Zhongshen will focus on reviewing key parameters such as CAS number,flash point and PH value,and assist enterprises to confirm the accuracy of HS Code.Whether it is ordinary chemical products or conditionally exempt hazardous chemicals,we can provide corresponding document rectification suggestions and logistics supporting schemes to ensure that goods clear customs at the fastest speed on the premise of compliance.

## Disassembly of the Whole Process Operation for Imported Eco-friendly Cleaning Agents

### Document Pre-review and Compliance Confirmation

Document pre-review is the first line of defense for the successful customs clearance of imported eco-friendly cleaning agents.Before the goods arrive at the port,Zhongshen will require foreign suppliers to provide detailed product information,including MSDS,component list,certificate of origin and packing declaration,etc.Our operation experts will strictly check the documents one by one against the latest 2026 edition of the List of Hazardous Chemicals and the international GHS standards.

The unique compliance requirement at this stage lies in label review.Imported eco-friendly cleaning agents must be affixed with Chinese hazard warning labels conforming to Chinese national standards (GB).If the product is a hazardous chemical,the Hazardous Chemicals Business License or relevant use qualification is also required.Zhongshen will assist enterprises to review whether the warning words and pictograms on the Chinese labels are accurate,so as to prevent port rectification notices caused by non-standard labels.For products with complex components,we will recommend filing components in advance to avoid customs valuation doubts caused by unknown components.

### International Transportation and Warehouse Management

According to the results of document pre-review,Zhongshen will arrange corresponding international transportation schemes.If the eco-friendly cleaning agent is classified as Class 3 flammable liquid or Class 8 corrosive substance,we must book space strictly in accordance with the International Maritime Dangerous Goods Code (IMDG) and use UN specification packaging.For non-hazardous chemicals,we will optimize general cargo channels to reduce costs.

In the warehouse management link,for eco-friendly cleaning agents with hazardous characteristics,Zhongshen has signed warehouses with hazardous chemical storage qualifications in Shanghai and surrounding areas.These warehouses are equipped with explosion-proof,leak-proof and temperature control facilities,which can meet the strict requirements of supervision for the storage of special chemicals.We will complete the warehousing declaration in advance to ensure that the goods can be quickly lifted from the port area after arrival,reducing terminal storage fees and potential inspection risks.

### Port Customs Declaration and Commodity Inspection Supervision

After the goods arrive at the port,Zhongshen will immediately start the customs declaration and inspection procedures.For imported eco-friendly cleaning agents,customs attaches equal importance to "document verification" and physical goods inspection.We will accurately fill in the "inspection and quarantine name" according to product attributes,and tick the correct hazardous attribute.

In the commodity inspection link,the customs may conduct sampling testing on the goods,and the testing items usually include flash point,closed cup flash point,component content,etc.The operators of Zhongshen will follow up the inspection site throughout the process,assist the customs staff to take samples safely,and send the samples to the designated laboratory for testing in time.Once there is a slight deviation between the test results and the declared data,we will quickly give a reasonable explanation to the customs with professional experience,or assist the enterprise to apply for recheck,so as to ensure smooth customs clearance to the maximum extent.

## Compliance Requirements and Risk Avoidance Practices

To more intuitively show the operation differences of imported eco-friendly cleaning agents under different attributes,we have compiled the following comparison table to help enterprises clarify their own compliance responsibilities.

| Supervision Link | Requirements for Ordinary Chemicals (Non-hazardous) | Requirements for Hazardous Chemicals (Containing Flammable/Corrosive Components) |
| --- | --- | --- |
| Document Review | Provide MSDS,non-hazardous guarantee letter,and component information shall be true. | Provide MSDS,public label,hazard warning label,which shall comply with GHS standards. |
| Packaging and Transportation | Ordinary cartons or barrels,no special UN marking requirements. | UN specification packaging must be used,showing UN number and dangerous goods mark. |
| Port Inspection | Mainly review outer packaging and Chinese label information. | Focus on inspection of hazardous attribute labels and packaging performance,with high probability of sampling and testing. |
| Storage Conditions | Ordinary dry warehouses are sufficient for storage. | Must be stored in special warehouses with hazardous chemical qualifications,and MSDS filing is required. |

In actual operation,enterprises must strictly prepare the following core documents,and the lack of any one may lead to blocked customs clearance.Zhongshen will assist enterprises to check the following list one by one:

- **Trade Documents:** Contracts,invoices,packing lists,bills of lading (shall be consistent with actual cargo information).
- **Product Technical Materials:** MSDS (Material Safety Data Sheet,which shall contain 16 items and be the latest version).
- **Compliance Documents:** Chinese hazard warning labels conforming to GB standards (for hazardous chemicals),declaration of conformity.
- **Qualification Certificates:** Business scope of the importer’s business license,Hazardous Chemicals Business License (if involved).
- **Other Documents:** Certificate of origin (provided when enjoying tariff preferences),insurance policy (required for hazardous chemical transportation).

## Practical Case Sharing: Customs Clearance Crisis Caused by Inconsistent Components

In early 2026,Ms.Cao,the procurement head of a precision machinery manufacturing enterprise in Shanghai,encountered a tricky import business.She imported a batch of eco-friendly water-based cleaning agents for cleaning metal parts from Germany.The foreign supplier claimed before shipment that the product was absolutely safe and not a hazardous chemical,so it was transported and declared as general cargo.

However,after the goods arrived at Shanghai Yangshan Port,the customs unpacked for inspection and took samples for testing.The test results showed that the closed cup flash point of the cleaning agent was only 55 degrees Celsius.According to the latest hazardous chemical classification standard implemented in 2026,the product belongs to Class 3 flammable liquid.As the enterprise did not declare according to hazardous chemical requirements,and there was no dangerous goods warning mark on the outer packaging,the customs determined that the batch of goods had serious safety hazards,immediately issued the Cargo Inspection Notice and required suspension of customs clearance,facing the risk of return or destruction,and Ms.Cao’s company might face high fines.

Ms.Cao urgently contacted Zhongshen for assistance.After taking over the case,our operation team did not choose to explain blindly,but quickly took remedial measures.First,we assisted Ms.Cao to communicate with the German technical department to re-obtain a detailed and true component analysis report and confirm the flash point data.Subsequently,we guided the enterprise to immediately reissue the relevant hazardous chemical operation compliance qualifications,and produced Chinese hazard warning labels conforming to national standards overnight.

When submitting the situation explanation to the customs,the professional customs declarer of Zhongshen explained in detail that the enterprise did not intentionally conceal the declaration,but had cognitive deviation on the differences between domestic and foreign standards,and showed the rectified label documents and subsequent compliance commitments.With our professional interpretation ability and perfect rectification plan,the customs finally recognized the enterprise’s remedial attitude and allowed the enterprise to release the goods after completing label rectification and paying the corresponding deposit.This case not only saved Ms.Cao hundreds of thousands of yuan in cargo value losses,but also made her deeply realize the key role of professional agencies in avoiding compliance risks.
