Dafey: Expert in International Shipping of Hazardous and Oversized Cargo
Created on 07.29
Let’s be honest—most freight forwarders shy away from complicated jobs. Especially when the cargo doesn’t fit inside a standard container… or comes with warning labels.
At Dafey Logistics, we built our reputation on saying yes to the hard stuff. Whether it’s oversized industrial equipment or hazardous chemical shipments, our team thrives on solving complex global transport challenges.
Because “difficult” doesn’t mean “impossible”—it just means you need the right partner.
If you’ve ever tried to ship bulky machinery, flammable liquids, or pressurized containers, you know this isn’t regular shipping.
Here’s why:
- Hazardous cargo must follow UN classification codes import/export regulations—all varying by country.
- Oversized cargo shipping container types, and sometimes even government escorts for road transport.
Every shipment becomes a project. And that’s exactly how we treat it.
A recent client needed to move a 17-meter-long heat exchanger from a manufacturing plant in Vietnam to a facility in the Netherlands.
Here’s what we did:
- Built a custom cradle for flat-rack ocean transport
- Coordinated port handling in Ho Chi Minh City with a bonded warehouse transfer
- Managed customs classification using the correct HS code and Incoterms
- Provided real-time shipment tracking throughout the 24-day journey
The result? Zero delays. Zero compliance issues. And one very happy engineering client.
Shipping dangerous goods internationally isn’t just about slapping a warning sticker on the box.
Let’s take lithium batteries, for example. These are now classified under Class 9 Dangerous Goods. That means:
- You need UN-certified packaging
- Documentation must include proper shipping name (PSN) and emergency contact numbers
- Not all airlines or carriers will even touch them—unless you’re working with a logistics partner who knows the ropes
Dafey works closely with air and sea carriers who are certified for hazmat handling, so your cargo never gets stuck on the tarmac or in port.
We get this question a lot—“Should we fly it or float it?”
Here’s a quick comparison:
Air Freight | Sea Freight |
|
Speed | 1–7 days | 15–60 days |
Cost | High | Moderate to Low |
Risk with Hazmat | Higher (many restrictions) | Lower (more flexibility) |
Cargo Size | Limited | Ideal for bulky/oversized |
Common Use | Small chemical shipments | Large-scale project cargo |
Tip: If your cargo is oversized, it likely won’t qualify for air freight at all—some airlines simply won’t accept it. That’s when ocean freight services become your best friend.
Forget speed or cost—if your paperwork isn’t perfect, your cargo doesn’t move. Period.
At Dafey, our international logistics services are built on one thing: compliance-first execution. That includes:
- Handling Incoterms properly to prevent surprise charges
- Ensuring cargo aligns with the correct freight class
- Managing customs documentation digitally for faster processing
- Building routes that comply with local transportation mode restrictions
Many providers overlook this and end up triggering fines, delays, or worse—cargo seizures. We don’t.
It’s easy to think of regulations as red tape—until your cargo is stuck at port, flagged for incorrect labeling, or worse, rejected entirely. With hazardous or oversized freight, the stakes are higher. One small mistake on a declaration form, or the wrong packaging code, can undo weeks of planning.
That’s why at Dafey, we treat compliance as part of the shipment—not an afterthought. From choosing the right Incoterms to verifying every customs form, we focus on getting it right the first time—so you don’t have to deal with surprises later.
Did you know? Incorrect packaging is one of the top 3 reasons hazardous cargo gets rejected at ports.
That’s why we provide:
- On-site packaging requirement consulting before dispatch
- Certified partners fo UN packaging and labeling
- Verification of shipping container types based on material class and destination climate
If it’s going from Shanghai to Saudi Arabia, you better believe temperature stability matters. We factor that in.
A common myth in international shipping is that freight consolidation always saves money.
Reality check: if your cargo is hazardous or oversized, mixing it with other shipments might not be allowed—or worse, it might increase your risk profile.
That’s why we offer:
- Dedicated container solutions for sensitive cargo
- Expert advice on when multimodal transport makes more sense
- Pre-shipment feasibility checks to minimize in-transit issues
Sometimes, solo shipping is actually the cheaper, faster, and safer choice.
Let’s break it down. For hazardous international shipping, you’ll typically need:
- MSDS (Material Safety Data Sheet)
- Dangerous Goods Declaration (DGD)
- Packing Certificate
- Commercial Invoice
- Certificate of Origin
- UN identification number + proper labels
According to the International Maritime Organization (IMO), these documents are mandatory under the IMDG Code for the safe and compliant transport of dangerous goods by sea.
And if it’s oversized? Add on dimension sheets, weight verification forms, and route permission documents (in many countries).
Need help with any of these? We handle the entire customs clearance process end to end.
Ask these questions:
- Can they handle both
international freight forwarding for bulky cargo and hazardous goods?
- Do they have experience in project cargo handling across continents?
- Do they offer bonded warehouse services to hold goods during inspections or rerouting?
- Do they proactively prevent errors with AI-based shipment tracking and alerts?
We check every box. And if you ask our clients, they’ll tell you—we go beyond just shipping. We protect your brand’s global flow.
Shipping oversized and hazardous cargo globally isn’t just about containers and codes. It’s about knowing how to move what others can’t—or won’t.
At Dafey Logistics, we build smart, compliant, and reliable routes across borders for clients who expect more than “standard.” If that’s you?
