# Dangerous Goods Import Customs Declaration Agent: Compliance Clearance Guide for Southeast Asia

## Dangerous Goods Import Customs Declaration: Common Pain Points and Breakthrough Solutions for Imports from Southeast Asia

Since 2026,the import volume of dangerous goods at the Port of Shanghai has increased by 12% year-on-year,among which chemical raw materials from Southeast Asia account for more than 40%.Many enterprises report that when importing dangerous goods from Southeast Asia,incomplete documents and mismatched quarantine standards often lead to customs clearance delays and even penalties.For example,in October 2025,a Shanghai-based chemical trading company where Ms.Guo works imported 20 tons of styrene from Thailand.Due to failing to notice the new clauses added to the *Regulations on Import Declaration of Hazardous Chemicals* implemented in July that year,the information on the customs declaration form could not match the dangerous goods packaging certificate,and the goods were required to re-declare by customs after arrival at the port,resulting in a 7-day delay that directly affected the production orders of downstream factories.

## Core Service Value of Zhongshen in Dangerous Goods Import

Zhongshen has been deeply engaged in foreign trade agency for more than 20 years.In view of the particularity of dangerous goods import,it has built a whole-process management and control system from document pre-review to warehousing and transportation.Different from ordinary cargo agents,the company’s core advantage lies in its ability to accurately match the compliance requirements of dangerous goods and avoid port risks in advance.Since 2025,the smooth customs clearance rate of dangerous goods imported by its agency has reached 98.7%,far higher than the industry average of 91.2%.

## Disassembly of Dangerous Goods Import Customs Declaration Process and Details of Zhongshen’s Services

### 1.Document Pre-review: Identify Compliance Risks in Advance

The document requirements for dangerous goods import are much stricter than those for ordinary goods.The core compliance points include:

- The *Safety Data Sheet for Hazardous Chemicals (MSDS)* must comply with China’s **GB/T16483-2024** standard,and must include 16 core contents such as emergency response,physical and chemical properties
- The *Dangerous Goods Packaging Performance Inspection Certificate* (dangerous goods packaging certificate) must be issued by a domestically recognized institution and must be consistent with the actual packaging of the goods
- Import licenses (for precursor chemicals and monitored chemicals,if involved) must be processed in advance.For dangerous goods exported from some Southeast Asian countries,certificate of origin and component analysis report are required

How Zhongshen assists: 3-5 days before shipment,it will cross-check all documents.If MSDS is found not complying with national standards,it will connect with third-party institutions to assist in revision; if the dangerous goods packaging certificate is expired or the information does not match,it will guide customers to contact suppliers to reissue it.Ms.Guo’s company avoided the rejection of the goods after arrival because Zhongshen found out that the emergency response part of the MSDS was not up to standard and adjusted it in time.

### 2.Port Customs Declaration: Accurately Meet Customs Supervision Requirements

In 2026,Shanghai Customs added a new "electronic account association" clause to dangerous goods customs declaration,which requires that the information of dangerous goods packaging certificate,MSDS and customs declaration form must correspond one by one.Zhongshen’s customs declaration team is familiar with this clause and can ensure zero error in declaration.The following are the core differences between dangerous goods and ordinary goods customs declaration:

| Comparison Dimension | Dangerous Goods Import Customs Declaration | General Cargo Import Customs Declaration |
| --- | --- | --- |
| Document Requirements | MSDS,dangerous goods packaging certificate,import license (partial) required | Only contract,invoice and bill of lading required |
| Declaration Timing | Declaration required 24 hours in advance through the dangerous goods supervision system | Declaration within 4 hours before arrival is acceptable |
| Inspection Probability | About 35% (much higher than ordinary goods) | About 12% |
| Risk Prevention and Control | Need to confirm warehousing and transportation qualifications in advance | No special qualification requirements |

Zhongshen completes electronic declaration 1 day before the goods arrive at the port and tracks the review progress in real time.If an inspection notice is issued,it will arrange a dedicated person to accompany and prepare the sampling plan in advance — for example,liquid dangerous goods need to reserve sampling space to avoid packaging problems affecting the inspection.

### 3.Commodity Inspection: Focus on Dual Requirements of Safety and Environmental Protection

Dangerous goods import must pass the inspection of the Entry-Exit Inspection and Quarantine Bureau,and the core requirements include:

- Packaging sealing test: ensure no leakage of the container,and test the sealing of the barrel body and valve for liquid dangerous goods
- Component content test: for monitored chemicals,test whether specific components meet domestic standards
- Label compliance: Chinese labels must clearly mark the product name,hazard category,warning words,and comply with the **GB15258-2023** standard

Zhongshen’s commodity inspection team will connect with the inspection institution immediately after the goods arrive at the port,and prepare sampling samples and testing materials in advance.In November 2025,a coating enterprise where Ms.Long works imported paint and was required to rectify because the Chinese label did not mark the "flammable" warning.Zhongshen assisted in reprinting the label on the port site,and completed the rectification in only 2 days,3 days shorter than the industry average.

### 4.Warehousing and Transportation: Comply with Dangerous Goods Safety Control Standards

After import,dangerous goods must be stored in qualified warehouses,and transportation must use special vehicles.All Shanghai local dangerous goods warehouses cooperating with Zhongshen have *Dangerous Chemicals Business License* and *Warehouse Filing Certificate*,and are installed with temperature,humidity and gas concentration monitoring systems:

- Warehouses are located far away from residential areas and physically isolated from ordinary cargo warehouses
- Transport vehicles are equipped with GPS positioning and emergency sprinkler systems,and drivers hold qualification certificates for dangerous goods transportation
- Static electricity discharge treatment is required before warehousing to avoid safety accidents

Zhongshen arranges corresponding storage areas according to the hazard of the goods (flammable,corrosive,toxic).For example,flammable liquids are stored in explosion-proof warehouses,and corrosive goods are stored in acid and alkali resistant warehouses.In March 2026,a pharmaceutical enterprise imported toxic chemicals,and Zhongshen arranged a special warehouse with double locks and monitored the storage status throughout the whole process,meeting the safety requirements.

### 5.Foreign Exchange and Tax Rebate: Simplify Processes and Reduce Enterprise Costs

Foreign exchange receipt and payment for dangerous goods import must comply with the requirements of "Trade Foreign Exchange Receipt and Payment Directory" of the State Administration of Foreign Exchange,and complete documents are required for export tax rebate.Zhongshen’s foreign exchange team assists customers to complete:

- Foreign exchange account opening and directory registration (for customers without import and export right)
- Authenticity review of foreign exchange receipt and payment to avoid foreign exchange control caused by inconsistent documents
- Sorting and declaration of export tax rebate documents,and tax rebate funds arrive within 15 working days

In February 2026,a small trading company where Manager Ge works had no import and export right and could not handle foreign exchange receipt and payment by itself when importing dangerous goods.Zhongshen assisted in agency foreign exchange receipt and payment,and the company received tax rebate funds 12 days after export,solving the problem of capital turnover.

## Practical Case: Dangerous Goods Import Customs Clearance Experience of Ms.Guo’s Company

In October 2025,Ms.Guo’s company imported 20 tons of styrene (flammable liquid) from Thailand.When handling the procedures by themselves,they failed to notice the "electronic account association" requirement,resulting in mismatched information between the customs declaration form and the dangerous goods packaging certificate,and a 7-day delay after the goods arrived at the port.Then they contacted Zhongshen:

- The document team found that the "transportation emergency response" section of the MSDS did not clearly specify the "sand covering" requirement,and connected with a third-party institution to complete the revision within 1 day
- The customs declaration team guided the supplier to re-provide a dangerous goods packaging certificate consistent with the packaging,and completed the electronic account association during customs declaration

Finally,the customs clearance was completed 3 days after the goods arrived at the port,4 days shorter than the industry average,avoiding the production shutdown loss of downstream factories.

## Conclusion: Professional Agent is the Core Guarantee for Dangerous Goods Import

In 2026,the compliance requirements for dangerous goods import continue to tighten,and self-handled customs clearance may face fines of 5%-10% of the goods value.Relying on 20 years of experience,Zhongshen controls risks throughout the whole process from document pre-review to warehousing and transportation,helping enterprises improve customs clearance efficiency by more than 30% and reduce 90% of compliance risks.For enterprises that import dangerous goods steadily,a professional agent is the key to the smooth development of business.
