From household goods and commercial products to vehicles, machinery, perishables and project cargo, understand what can be transported by ocean freight and how different cargo types are handled.
Sea freight is designed to move a remarkably broad range of goods between international markets. For Pacific Island destinations, containerized shipping is especially important: much of the region's general cargo imports and exports move through scheduled container services. That includes everyday commercial products, food and household supplies, construction materials, manufactured goods, machinery, spare parts and many other commodities that can be safely packed into a standard shipping container. :contentReference[oaicite:1]{index=1}
However, not every shipment should be treated as ordinary container cargo. The dimensions, weight, value, temperature requirements, physical characteristics and regulatory status of the goods can determine whether the shipment should move as FCL, LCL, refrigerated cargo, break bulk, vehicle cargo, project cargo or dangerous goods. The right question is therefore not simply whether an item can travel by sea, but whether it can be transported safely, legally and economically using an appropriate ocean freight method.
Different products require different approaches to packing, container selection, documentation and handling. These are some of the most common categories found in international sea freight.
General cargo includes manufactured products, household goods, retail merchandise, equipment, spare parts and other non-hazardous goods that can normally be packed and secured inside a standard container.
Businesses regularly use ocean freight for inventory, wholesale products, building supplies, packaging materials, furniture and other goods moving between international markets.
Personal effects and household belongings can often be transported by sea, particularly when the shipment is too large or economical for air freight.
Timber, building products, fixtures, tools, fittings and other construction-related cargo can form an important part of containerized sea freight.
Industrial machinery, agricultural equipment and other large items may move by container, flat rack, open-top container or break-bulk service depending on their dimensions and weight.
Cars, trucks, buses, motorcycles and other wheeled equipment can be transported by sea through container, Ro-Ro or specialized vehicle shipping arrangements.
The standard shipping container has transformed international logistics because cargo can be packed, secured, moved between trucks and vessels, stored at terminals and transferred between different parts of the transport network without repeatedly handling each individual item. This makes containerization particularly useful for Pacific trade, where cargo may pass through international gateway ports and regional transshipment hubs before reaching a smaller island destination.
The appropriate container depends on the cargo itself. A standard dry container may be suitable for ordinary packaged goods, while oversized machinery may require an open-top or flat-rack solution. Temperature-sensitive products may require a reefer container, while certain cargoes may need specialist packing or securing. The container is therefore part of the cargo planning decision, not simply a box chosen after the shipment has been booked.
Compare 20ft and 40ft Containers โOne of the first decisions for containerized cargo is whether to use a Full Container Load or Less than Container Load service. FCL is generally suited to cargo that can efficiently use an entire container, while LCL allows smaller shipments to share container space with cargo belonging to other shippers. The choice can depend on cargo volume, dimensions, handling requirements, destination and overall shipping economics.
For smaller Pacific shipments, LCL can make international sea freight practical without requiring the shipper to fill an entire container. Consolidated cargo is packed together before ocean transport and later separated during destination handling. Larger shipments may benefit from the control and dedicated space of FCL, particularly when the cargo is dense, valuable, fragile or requires specialized loading.
Learn About LCL Shipping โ Learn About FCL Shipping โSize, weight, temperature, handling requirements or regulatory classification can change the way cargo needs to be shipped.
Perishable food, seafood, pharmaceuticals and other temperature-sensitive goods may require refrigerated containers and appropriate temperature planning.
Machinery and other goods that cannot fit within the dimensions of a standard container may require flat racks, open-top equipment or alternative transport arrangements.
Break-bulk cargo is used for goods that are not practical to transport inside standard containers, including certain oversized machinery, structural steel and heavy equipment.
Large industrial components, infrastructure equipment and heavy-lift cargo may require detailed route, vessel, lifting and port planning.
Perishable goods are not necessarily excluded from ocean freight. Food products and other temperature-sensitive cargo can be transported using refrigerated containers, commonly known as reefers, when the appropriate service is available. The cargo must be evaluated for its temperature range, shelf life, packaging and expected transit conditions before booking.
This becomes particularly important for Pacific routes because cargo may spend significant time inside the container, including during port handling or transshipment. Guidance for sea cargo planning notes that temperature requirements should be identified in advance and that food cargo may require preparation for longer storage. :contentReference[oaicite:2]{index=2}
Vehicles and rolling equipment are another important category of ocean cargo. Depending on the destination, carrier and equipment available, vehicles may travel inside suitable containers or through specialized roll-on/roll-off services. Larger commercial vehicles and machinery may require a different loading arrangement altogether.
Vehicles can also introduce additional regulatory considerations. For example, certain vehicles containing lithium batteries can fall under dangerous-goods requirements depending on their configuration and applicable maritime rules. Carrier requirements can therefore differ from ordinary general cargo, making it important to declare the vehicle accurately before booking. :contentReference[oaicite:3]{index=3}
Dangerous goods are not automatically prohibited from ocean transport. They are subject to classification, packaging, marking, documentation, segregation and stowage requirements.
The cargo must be correctly identified and classified according to the applicable dangerous-goods requirements.
Dangerous goods require appropriate packaging and preparation so that the cargo can be safely transported.
Correct marks, labels and documentation help carriers and terminals identify the hazards associated with the cargo.
Certain dangerous goods must be separated from incompatible cargo and stored according to maritime safety requirements.
Not every piece of cargo is designed to fit inside a standard 20-foot or 40-foot container. Machinery, structural steel, cranes, industrial equipment and other oversized goods may require break-bulk, flat-rack, open-top or heavy-lift arrangements. Pacific shipping studies identify over-dimensional machinery, trucks, buses, industrial project cargo and cargo-handling equipment among examples of break-bulk freight. :contentReference[oaicite:4]{index=4}
Project cargo requires much more planning than simply reserving vessel space. The dimensions and weight of each item, lifting equipment, vessel compatibility, port infrastructure, road access and final delivery route all need to be considered. A suitable solution may therefore involve a combination of ocean transport, specialized handling and inland logistics.
Understand Pacific Port Infrastructure โShipping lines and destination authorities can restrict or prohibit certain commodities. Some goods may require permits, certificates, special packaging or prior approval. Others may be prohibited entirely under the laws of the origin, destination or transit country. This can include certain hazardous substances, controlled products, restricted biological materials and other regulated commodities.
Even ordinary-looking goods can create problems if they contain batteries, chemicals, compressed gases, flammable substances or other regulated components. The safest approach is to describe the cargo accurately rather than relying only on a general product name. Carriers and freight professionals can then determine the correct classification and shipping requirements.
A cargo assessment helps determine the right equipment, service and documentation before the shipment reaches the port.
Identify the exact product, material, composition and intended use rather than relying on a broad description.
Dimensions and weight determine whether standard containerization is practical or specialist equipment is required.
Perishable or temperature-sensitive goods may require refrigerated equipment and specific handling procedures.
Batteries, chemicals, fuels and other potentially hazardous goods may require dangerous-goods classification and additional documentation.
Once the cargo has been identified, the next step is deciding how it should be packed, protected, measured and presented for international transport. Standard cargo may need secure internal packing and appropriate weight distribution, while fragile, oversized, temperature-sensitive or hazardous goods require more specialized preparation.
Accurate information is particularly important when shipping into Pacific destinations because the cargo may pass through several stages of the maritime network. A shipment can move from the origin terminal onto a mainline vessel, through a transshipment hub and onto a smaller feeder service before reaching the final island port. Pacific shipping networks are often structured around this hub-and-spoke model. :contentReference[oaicite:5]{index=5}
Read the Cargo Preparation Guide โ
A pallet of packaged commercial goods, a refrigerated food shipment, a family vehicle and an oversized industrial machine may all travel by sea, but they do not necessarily use the same equipment or service. Their cargo characteristics influence container selection, handling, documentation and the type of vessel or service that can carry them.
Destination infrastructure matters too. Pacific islands can have very different port capabilities, and some international gateway ports connect onward to smaller destinations through regional services. Port capacity, handling equipment, storage and local transport can all influence whether a particular cargo solution is practical. :contentReference[oaicite:6]{index=6}
