# Full Analysis of the Whole Process of Import Customs Declaration for Dangerous Goods: Key Steps from Document Preparation to Port Release

## Import of Chemical Dangerous Goods: A Compliance Journey From Germany to Shanghai

In 2026,importing high-performance resins,special solvents or lithium battery raw materials from industrial countries such as Germany and Japan has become a normal practice in China’s high-end manufacturing field.These goods are usually classified as dangerous goods specified in the International Maritime Dangerous Goods Code or the Catalogue of Hazardous Chemicals.When enterprises handle import on their own,they generally face several practical difficulties: the safety data sheet provided by overseas suppliers may not meet the format and content requirements of China Customs; it is difficult to accurately match the specific entry of the goods in the Classification Information Table of Hazardous Chemicals; some ports have additional regulations on packaging and marking of dangerous goods,and information asymmetry easily leads to failure of declaration after goods arrive at the port.

Targeting these pain points,Zhongshen’s import agency service plays the role of pre-planning and full-process execution.The service does not start when goods arrive at the port,but intervenes immediately after the customer confirms the overseas purchase contract.Through preliminary analysis of product composition,application and packaging method,we judge regulatory conditions in advance,sort out a clear import schedule and document list for customers,and avoid the risk of port storage fee or return shipment caused by insufficient preparation.

## Phased Disassembly: Core Links of Dangerous Goods Import Customs Declaration

The import process of dangerous goods is closely linked,and any omission in any link may trigger a chain reaction.Zhongshen’s operation system divides it into three main stages,and sets special control points according to the characteristics of dangerous goods.

### Stage 1: Document Pre-audit and Compliance Planning

The core of this stage is accurate classification and document compliance.The category,item and packaging type of dangerous goods directly determine regulatory requirements and tax rate.For example,an imported adhesive may have both flammable liquid and health hazard characteristics,and wrong classification will lead to deviations in all subsequent links.

Supervisor Qin from Zhongshen pointed out that they usually conduct cross-checking based on the foreign MSDS provided by customers,combined with China’s *Classification and Labeling Specification of Hazardous Chemicals*.When necessary,they will recommend customers to send samples in advance to the dangerous goods classification and identification institution designated by the customs to obtain the legally effective *Classification and Identification Report of Hazardous Characteristics*.This report is the foundation of all subsequent customs clearance activities.

Preparation of key documents is also completed at this stage.In addition to conventional documents including contract,invoice,packing list and bill of lading,the following items require special attention for dangerous goods import:

| Hazard Category | Key Documents | Key Support From Zhongshen |
| --- | --- | --- |
| Flammable liquids/gases,corrosives,etc. | Result Certificate of Use Identification for Transport Packaging of Export Dangerous Goods (commonly known as Dangerous Goods Packaging Certificate) | Verify whether the dangerous packaging certificate issued overseas meets Chinese standards,and guide suppliers to revise. |
| Goods listed in the Catalogue of Hazardous Chemicals | Compliance Declaration for Imported Hazardous Chemicals by Operating Enterprises and sample of Chinese hazard notification label | Draft declaration documents according to regulations,review and translate to produce Chinese label templates that meet national standards. |
| Class 9 dangerous goods such as lithium batteries | UN38.3 test report,1.2m drop test report,etc. | Verify the validity of the report to ensure that transportation test requirements are met. |

### Stage 2: Port Declaration and Inspection Cooperation

After goods arrive at Shanghai Port or airport,formal customs declaration starts.There are special requirements for filling in dangerous goods customs declaration form.For example,columns such as "Product Hazard Mark","UN Number","Dangerous Goods Packaging Mark" must be filled accurately.Zhongshen’s customs declaration system has built-in verification rules that can automatically check common errors before declaration.

The port inspection rate of dangerous goods is usually higher than that of ordinary goods.Inspection instructions may come from customs’ doubts about commodity classification or price,or from random inspections of dangerous goods transportation safety by the maritime department.Once an inspection notice is received,rapid and professional response is crucial.

Mr.Wen once handled a batch of epoxy resin curing agent imported from South Korea.After goods arrived at the port,the customs required inspection of the dangerous goods packaging.Since Zhongshen had confirmed the compliance of the dangerous goods packaging certificate in the pre-audit stage and submitted relevant electronic documents to the port system in advance,on-site customs officers could verify the information by scanning the code.At the same time,Supervisor Weng coordinated warehouse staff to move the goods to be inspected to the special dangerous goods inspection site in advance,and prepared unpacking tools and safety protection equipment.The entire inspection process was completed within 2 hours,without affecting the subsequent pickup plan.

For hazardous chemicals in the legal inspection catalogue,it is also required to declare to the customs and accept inspection and quarantine.Inspection content may include checking consistency between actual goods and declared information,checking whether Chinese hazard notification labels are posted properly,and even sampling for laboratory testing.Zhongshen will accompany the inspection to ensure smooth communication,and provide technical data support for questions raised by inspectors.

### Stage 3: Dangerous Goods Warehousing and Domestic Transportation

After customs clearance and release,dangerous goods cannot enter ordinary warehouses.Enterprises need to transfer them to dangerous goods warehouses with corresponding qualifications for storage.The warehousing network cooperating with Zhongshen covers all major port areas in Shanghai,and can match warehouses with Class A,Class B or Class C storage qualifications according to the hazard level of goods.

Short-haul transportation from the port to the warehouse must also be completed by fleets with dangerous goods transportation qualifications.Transport vehicles must be equipped with corresponding fire-fighting equipment and warning signs,and drivers and escorts must hold valid certificates for work.Zhongshen will review the qualification documents of the transportation company,and supervise them to drive safely according to the scheduled route.

The risk often overlooked at this stage is liability definition in the domestic transportation link.Ms.Xin recommends that customers clearly specify in the contract who bears the transportation safety responsibility from the time goods leave the port supervision area to entering the designated warehouse.Zhongshen’s standard operating procedure requires the transporter to sign a safety commitment,and purchase sufficient cargo transportation insurance to minimize the potential loss of customers.

## Value of Professional Agency: Efficiency Improvement and Closed-loop Risk Management

Looking back at the whole process,the complexity of dangerous goods import is reflected in multiple levels of regulations,technology and operation.Enterprises without enough experience are easy to fall into the following predicaments:

- Repeated modification of declaration at the port due to document problems,resulting in high container detention fees.
- Being required to pay back taxes or facing administrative penalties due to wrong classification.
- Goods being ordered to be returned or destroyed due to unqualified packaging or labeling.
- Safety accidents and legal disputes caused by non-compliance in warehousing or transportation links.

With more than 20 years of deep cultivation in the industry,Zhongshen has accumulated a large number of practical cases and databases of different categories of dangerous goods.This experience is converted into the ability to predict risks and accurately control processes.Its value is not only completing customs declaration,but also helping enterprises avoid pitfalls through early compliance planning; guaranteeing customs clearance efficiency through professional declaration and inspection cooperation in the medium term; ensuring safe delivery of goods through closed-loop management in the later stage.Ultimately,enterprises can focus their limited energy on market development and R&D,and entrust complex import compliance affairs to a reliable partner.
