Can Dangerous Goods Be Transported Together with Other Cargo?

Can Dangerous Goods Be Transported with Other Cargo?

When planning logistics, many companies consider shipping dangerous goods together with general cargo to improve efficiency and reduce costs.

 

However, according to the IMDG Code (International Maritime Dangerous Goods Code) and related regulations, such arrangements must be carefully evaluated and planned to ensure safety and full compliance.

 

Basic Principles of Dangerous Goods Transport

Dangerous goods include a wide range of substances with inherent risks, such as:

• Flammable liquids
• Corrosive substances
• Toxic gases
• Oxidizers, explosives, etc.

Under the IMDG Code, these substances are divided into different classes, and each class has specific requirements for:

• Packaging
• Labeling and documentation
• Segregation and stowage
• Emergency response

 

Can Dangerous Goods Be Shipped with Other Cargo?

Whether dangerous goods can be transported together with other cargo depends on several key factors:

 

1. Class and Nature of the Dangerous Goods

Some dangerous goods must not be shipped together because they may react with each other and cause:

• Fire
• Explosion
• Release of toxic gases

For example:

• Oxidizing substances (Class 5.1) must not be loaded together with flammable materials (Class 3) in many situations, because they can greatly increase the risk of combustion.

 

2. Packaging and Labeling

Even when the dangerous goods are chemically compatible with other cargo, the following are still mandatory:

• Packaging must comply with IMDG performance standards (UN-approved packaging where required).
• Each package must be correctly labeled and marked, including:
  • Proper class labels and UN numbers
  • Handling marks and orientation arrows where applicable

This ensures that all parties in the logistics chain can identify and handle the cargo correctly.

 

3. Mode of Transport and Route Restrictions

Certain:

• Transport modes (e.g. specific vessel types, routes, or terminals), or
• Geographical areas and regulations

may impose additional restrictions on:

• The classes of dangerous goods allowed, and
• Whether co-loading with general cargo is permitted.

Before arranging combined transport, it is essential to confirm the applicable rules with carriers and local authorities.

As a professional service provider for dangerous goods container transport, WuSin Transportations Co., LTD. recommends the following:

 

1. Conduct Case-by-Case Risk Assessment

Before deciding to transport dangerous goods together with other cargo, always:

• Review each shipment’s substance classification, UN number, and packing group
• Evaluate chemical compatibility and potential interactions
• Assess temperature, ventilation, and stowage conditions

Only after confirming that the combination is allowed and safe should co-loading be considered.

 

2. Strict Compliance with Regulations

• Follow the IMDG Code and all relevant international and local regulations.
• Ensure that documentation, packaging, labels, and segregation all meet the required standards.
• Keep up to date with regulatory changes that may affect stowage and segregation rules.

 

3. Ensure Proper Training

• All personnel involved in handling, loading/unloading, and transporting dangerous goods should receive appropriate dangerous goods training.
• Staff should be familiar with:
  • Hazard classes and labels
  • Emergency response procedures
  • Basic first-aid and incident reporting steps

Good training significantly reduces the risk of human error.

 

Conclusion

In some cases, dangerous goods can be transported together with other cargo, but only when:
