When it comes to international shipping, few categories cause as much confusion as Class 9 hazardous materials. In this guide, we’ll explain what Class 9 hazmat is, and outline the packaging, documentation, labeling, and placarding rules you need to follow.
What is a Class 9 hazmat?
Class 9 Hazmat refers to miscellaneous hazardous materials that present risks not covered by Classes 1 to 8. In simpler terms, they are materials that may be harmful to people, property, or the environment under specific conditions. But don’t neatly fall under the “traditional” danger categories like flammable liquids or corrosives.
Typical examples include:
- Lithium batteries (UN3480 Lithium-ion batteries, UN3481 Batteries contained in or packed with equipment)
- Dry ice (carbon dioxide, solid)
- Asbestos materials
- Polychlorinated biphenyls (PCBs)
- Magnetized materials
- Elevated-temperature substances
- Environmentally hazardous liquids or solids (marine pollutants, waste materials)
Each of these items requires specific handling, packaging, and labeling to ensure safety during air or ocean transport.
Hazmat Class 9 shipping requirements
1. Packaging requirements
Packaging is one of the most critical parts of compliance. You must pack Class 9 materials in UN-certified packaging that has been tested for performance under pressure, vibration, and drop conditions.
- Use inner and outer packaging when required.
- Always ensure no contact between incompatible materials.
- Prevent leaks, punctures, or short circuits.
- Follow the packing instructions specified in the IATA DGR or IMDG Code.
- For lithium batteries, the packaging must also include protection and insulation against movementand fire hazards.
2. Documentation required
For Class 9 hazmat shipping, you’ll generally need:
- Safety Data Sheet (SDS): Provides chemical composition and handling information.
- Shipper’s Declaration for Dangerous Goods (DGD): Mandatory for most air shipments unless exempt.
- Air Waybill (AWB) or Bill of Lading (B/L): Must include the proper shipping name, UN number, and class.
- Packing list and invoice: For customs clearance and compliance.
- Emergency contact information
Failure to provide the correct documents can result in shipment rejection or penalties. Always verify with your freight forwarder before dispatch.
3. Labeling and placarding requirements
One of the most common questions shippers ask is:
“Does Class 9 hazmat require placards?”
The answer depends on quantity and transportation mode.
For air shipments, placards are not required on individual packages, but labels are mandatory. The Class 9 hazmat label is a white-and-black striped diamond with the number “9” at the bottom.
On the other hand, placards are a larger version of the label, displayed on transport vehicles or containers. These are required when the total quantity exceeds 454 kg (1,001 lbs) of Class 9 material in one vehicle or container.
Weight limits and quantity restrictions
Class 9 hazmat weight limits vary depending on the material and shipping methods:
When transporting by air:
Airlines follow IATA Dangerous Goods Regulations, which limit the amount of Class 9 material per package (especially for lithium batteries). For instance, UN3480 lithium-ion batteries may have maximum net weight limits of 35 kg per package.
For ocean freight, there are generally no strict weight limits, but you must comply with IMDG Code segregation, packaging, and stowage requirements.
At ASLG, we can help you comply with weight restrictions and design the right transport solution for your shipment.
Air vs. sea shipping: Key differences
For businesses moving larger volumes, a 40ft container offers nearly double the space of a 20ft unit, making it the preferred choice for break-bulk cargo, furniture, or high-volume retail orders.
Below are estimated costs for shipping a 40ft container from major Chinese ports to Australia’s key destinations:
| Aspect | Air Shipping (IATA) | Sea Shipping (IMDG) |
|---|---|---|
| Speed | Faster, but more restrictive | Slower, but more flexible |
| Quantity limit | Strict per-package limits | Higher allowance |
| Documentation | Requires Shipper’s Declaration | Usually listed on the Dangerous Goods Manifest |
| Packaging | Lightweight, fireproof materials | Heavy-duty containers acceptable |
| Cost | Higher due to safety controls | More economical for bulk cargo |
In practice, many shippers use air freight for smaller, time-sensitive shipments, while ocean freight is more cost-efficient for large or heavy Class 9 shipments.
Compliance tips for Class 9 hazmat shippers
- Always check the latest IATA and IMDG updates because regulations are revised annually.
- Ensure your SDS and DGD match the latest UN numbers and hazard descriptions.
- Train your team in hazmat identification, documentation, and emergency response.
- Work with certified freight forwarders experienced in Class 9 hazmat shipping requirements.
- Inspect labels and packaging before dispatch—non-compliance can lead to fines or cargo rejections.
- Provide accurate SDS and UN details to your logistics provider to avoid delays at customs.
