Breakbulk and RoRo shipping from China — moving cargo that doesn't fit in a box

Most cargo from China moves in containers. A 20-foot or 40-foot steel box is an enormously efficient unit — standardized, stackable, trackable, transferable between ship, train, and truck without touching the goods inside. For 95% of what gets exported, it works perfectly.

The other 5% doesn't fit. Construction machinery, agricultural equipment, power generation components, wind turbine blades, yachts, military vehicles, or fabricated steel structures that are too long, too heavy, or too irregularly shaped for a standard box. These move as breakbulk or RoRo cargo.

What is breakbulk shipping?

Breakbulk is cargo that is loaded individually onto a vessel rather than inside a standardized container. It might be:

• A crane loaded directly into a ship's hold using the vessel's own gear
• Machinery skidded and strapped to a flat rack or open-top container
• Fabricated steel beams or industrial equipment loaded as individual pieces
• Project cargo assembled from multiple components shipped together

The term "breakbulk" comes from historical shipping where loose goods — grain, timber, metal bars — were loaded piece by piece. Modern breakbulk still refers to cargo handled as distinct units rather than containerized.

Breakbulk vessels are general cargo ships designed with wide hatches, large holds, and often on-deck cranes capable of handling heavy or unusual lifts. They can accommodate cargo that won't fit in any container and don't require port infrastructure designed for containers.

Flat rack and open-top containers are a hybrid approach — technically containerized, but designed for cargo that overhangs the sides or can't be enclosed. A flat rack is a container with no sides and a reinforced floor. An open top has removable tarpaulin rather than a fixed roof. These still move on container ships and can be stacked, but they allow outsized dimensions. If your machinery is oversized but not enormous, this is often the most cost-effective option.

What is RoRo shipping?

RoRo — roll-on/roll-off — is a vessel type designed for wheeled cargo. The ship has a built-in ramp, and vehicles or equipment drive on at the origin port and drive off at the destination. Nothing is lifted by crane. The cargo rolls on, travels on the car decks, and rolls off.

What moves by RoRo:

• Passenger cars and light commercial vehicles exported from Chinese manufacturers
• Heavy trucks, buses, and coaches
• Agricultural machinery — tractors, combines, harvesters
• Construction equipment with wheels or tracks — excavators, bulldozers, wheel loaders (tracked equipment can be loaded on trailers)
• Mining equipment
• Yachts and boats on cradles

RoRo is the dominant mode for vehicle exports from China. Chinese automakers exporting to Southeast Asia, the Middle East, Africa, and increasingly Europe ship primarily by RoRo. The vessels are built specifically for vehicle logistics — weather-protected decks, securing systems, and efficient terminal turnaround at both ends.

RoRo vs container — why not just put a car in a box?

It's a fair question. Vehicles can be and sometimes are containerized — typically when the destination has poor RoRo port infrastructure, or for high-value cars that benefit from enclosed container protection.

But containerizing a vehicle is slow and labor-intensive. The car must be driven in, secured, fuel partially drained, battery disconnected, and the container doors sealed. At the destination, the process reverses. RoRo loads and discharges in a fraction of the time — a typical vehicle takes 15–20 minutes to drive on or off a RoRo vessel.

At scale, that efficiency difference is enormous. A RoRo ship can carry 6,000–8,000 vehicles and discharge them in a day. The same cars in containers would require far more port time and container handling equipment.

For standard passenger vehicles at volume, RoRo is almost always the right answer from China.

Project cargo — when it gets complicated

Project cargo refers to large, complex, and often one-of-a-kind shipments — infrastructure components, power plant equipment, offshore platform parts, complete factory machinery. These shipments often combine multiple modes and multiple vessel types:

• Some components may be containerized on standard vessels
• Heavy lifts move by heavy-lift vessel (semi-submersible or heavy-lift ships with enormous crane capacity)
• Wheeled equipment moves by RoRo
• Oversize components move by breakbulk

A single project shipment might require a specialized freight forwarder with project logistics experience to coordinate all of it under one plan.

Ports and infrastructure

Not every Chinese port handles breakbulk and RoRo equally well. Major hubs for non-containerized cargo from China include:

• Guangzhou (Nansha) — large vehicle export terminal, major RoRo hub
• Tianjin — significant vehicle and project cargo exports, northern China
• Wuhan — inland port accessible by river, important for central China project cargo
• Shanghai — handles breakbulk alongside its container volume

When booking breakbulk or RoRo from China, port selection matters more than on standard container routes because vessel frequency is lower and specialized berths are fewer.

What breakbulk and RoRo cost

Pricing for non-containerized cargo is less standardized than container rates and varies significantly by:

• Weight and dimensions (extremely important — heavy-lift surcharges apply to cargo above certain weight thresholds)
• Port of loading and discharge
• Vessel type required
• Season and vessel availability
• Special handling requirements (lashing, blocking, bracing, engineering surveys for heavy cargo)

For cargo that borderlines between oversized container and breakbulk, run both scenarios — a flat rack on a container service is often faster and cheaper than a breakbulk sailing, if your dimensions allow it.
