Shipping Hazardous Cargo? Here Are 10 Things You Should Know

Shipping hazardous cargo requires precision, expertise, and unwavering attention to safety protocols. Whether you're transporting chemical compounds, industrial equipment, or specialized materials, understanding the critical requirements can mean the difference between seamless delivery and costly delays, or worse, safety incidents.

At ARI Shipping Corporation, we've spent over four decades mastering the complexities of hazardous cargo shipping. Here are the 10 essential things you need to know before your next hazardous shipment.

1. Master the Art of Classification and Identification

Your first step is always proper classification. Every hazardous material must be accurately identified according to international standards, including the United Nations' Recommendations on the Transport of Dangerous Goods and the International Air Transport Association's (IATA) Dangerous Goods Regulations.

Your basic description must include:

• UN identification number
• Proper shipping name
• Hazard class or division
• Packing group designation

Without precise classification, you're setting yourself up for regulatory violations, shipment delays, and potential safety risks. Don't guess: verify every detail before proceeding.

2. Packaging: Your First Line of Defense

Proper packaging isn't optional: it's your cargo's lifeline. All hazardous materials must be packaged in United Nations Performance Oriented Packaging (UN POP) unless specific exceptions apply under Title 49 Code of Federal Regulations.

Key packaging requirements by weight:

• Up to 20 lbs: Minimum 200-lb bursting test or 32-edge crush test package
• 21-50 lbs: 200-lb bursting test or 32-edge crush test package
• 51-70 lbs: 275-lb bursting test or 55-edge crush test package

Your packaging must be in new or "like new" condition: carriers will reject compromised containers. Consider combination packaging with absorbents, padding, leak-proof containers, and appropriate outer packaging.

3. Crystal-Clear Labeling and Marking

Visibility saves lives. Every hazardous cargo package requires proper warnings, UN numbers, and internationally recognized symbols. These labels aren't just regulatory requirements: they're critical communication tools for transport workers and emergency responders.

Essential marking elements:

• Proper shipping name
• UN identification number
• Hazard class symbols
• Orientation arrows (when required)
• Emergency contact information

4. Documentation That Travels With Your Cargo

Paperwork problems can ground your shipment instantly. Your Dangerous Goods Declaration must contain complete details about materials, hazard levels, and emergency response information.

For air transport specifically, you'll need:

• Shipper's Declaration for Dangerous Goods
• Air Waybill documentation
• Emergency response information
• 
  

Pro tip: This documentation must always accompany your shipment: no exceptions.

5. Training and Certification: Non-Negotiable Requirements

Every person touching your hazardous cargo must be properly trained. This includes awareness of different hazard types, emergency response procedures, and proper packaging techniques.

Certification requirements:

• DOT recertification is required every two years in the United States
• IATA certification for air transport personnel
• IMO training for maritime shipments
• Mode-specific training for road and rail transport

Don't risk it: ensure your team meets all training requirements before handling hazardous materials.

6. Material Compatibility: Preventing Dangerous Reactions

The wrong combination can be catastrophic. Some hazardous materials can interact to create fires, explosions, or toxic releases. You must thoroughly research compatibility before combining materials in shipments.

Compatibility considerations:

• Chemical reaction potential
• Heat generation risks
• Gas emission possibilities
• Container material interactions

Many carriers accept up to three compatible hazardous materials in one UN POP specification package, but only if they're truly compatible.

7. Choose Your Transport Mode Strategically

Different modes, different rules. Air, sea, road, and rail transport each have specific regulations, equipment requirements, and restrictions.

Key selection factors:

• Material type and hazard class
• Distance and transit time requirements
• Accessibility needs
• Cost considerations
• Special equipment availability

Some materials are prohibited on certain transport modes: plan accordingly to avoid costly route changes.

8. Performance Testing and Compliance Verification

Your containers must pass rigorous testing. Before use, packaging must complete various performance tests, including drop tests, leakproofness tests, hydrostatic pressure tests, and stacking tests.

Standard test categories:

• Drop tests from specified heights
• Leakproofness verification
• Hydrostatic pressure resistance
• Stacking strength assessment
• Vibration standards compliance
• Chemical compatibility testing

Both packaging manufacturers and shippers must ensure containers can pass prescribed tests.

9. Emergency Response Planning: When Things Go Wrong

Hope for the best, prepare for the worst. Even with perfect planning, accidents can occur. Your emergency response plan must detail procedures for spills, leaks, fires, and exposure incidents.

Essential emergency elements:

• Immediate response procedures
• Emergency contact information
• Specialized cleanup requirements
• Personnel protection protocols
• Environmental protection measures

Train your staff thoroughly: their quick, proper response can prevent minor incidents from becoming major disasters.

10. International Compliance and Continuous Improvement

Global shipping means global regulations. International shipments must comply with multiple regulatory frameworks, including the International Maritime Dangerous Goods Code, IATA Dangerous Goods Regulations, and UN Model Regulations.

Stay compliant by:

• Regularly reviewing shipping policies
• Updating training programs
• Monitoring regulatory changes
• Conducting internal audits
• Working with experienced logistics partners
• 
  

Failure to comply can result in delays, penalties, or legal action, none of which your business can afford.
