Types of Shipping Containers and Their Uses
Shipping containers are standardized cargo units used to transport goods by sea, road, and rail.
Different products require different container types. Standard packaged goods may fit inside a dry container, while temperature-sensitive cargo may require a reefer container. Heavy machinery may need an open top or flat rack container.
Choosing the right container helps reduce cargo damage, loading problems, and unexpected shipping costs.
What Is a Dry Container?
A dry container is the most common type of shipping container.
It is used for general cargo that does not require temperature control.
Typical products include:
Textiles
Furniture
Electronics
Machinery parts
Packaged food
Plastic products
Paper products
Spare parts
Dry containers are commonly available in 20-foot and 40-foot sizes.
What Is a 20-Foot Container?
A 20-foot container is often used for smaller but heavier shipments.
It may be suitable for:
Metal products
Machinery components
Marble
Chemicals
Heavy palletized cargo
A 20-foot container may be more practical when cargo is dense and heavy.
What Is a 40-Foot Container?
A 40-foot container provides more internal space than a 20-foot container.
It is commonly used for:
Furniture
Textiles
Electronics
Consumer goods
Lightweight but bulky products
Large commercial shipments
Cargo weight and volume should both be considered before choosing a container.
What Is a High Cube Container?
A high cube container is taller than a standard dry container.
It is usually available in a 40-foot size and provides additional internal volume.
High cube containers may be useful for:
Furniture
Plastic products
Textile bales
Packaging materials
Large boxes
Lightweight machinery
They are especially useful when cargo is bulky but not extremely heavy.
What Is a Reefer Container?
A reefer container is a temperature-controlled shipping container.
It is used for products that must remain within a specific temperature range during transportation.
Common examples include:
Meat
Seafood
Fruit
Vegetables
Dairy products
Pharmaceuticals
Vaccines
Chemicals
Frozen food
Reefer shipping may require temperature monitoring, ventilation, humidity control, and a reliable power supply.
What Is an Open Top Container?
An open top container does not have a fixed metal roof.
The top may be covered with a removable tarpaulin.
It is suitable for cargo that must be loaded from above using a crane.
Typical uses include:
Large machinery
Industrial equipment
Construction materials
Tall cargo
Glass
Marble
Heavy components
Open top containers are useful when cargo cannot fit through standard container doors.
What Is a Flat Rack Container?
A flat rack container has no fixed side walls or roof, or has only limited end walls.
It is designed for oversized, wide, or heavy cargo.
Common examples include:
Construction machinery
Industrial machines
Pipes
Boats
Generators
Transformers
Large steel structures
Cargo must be secured carefully using suitable lashing and support equipment.
What Is a Tank Container?
A tank container is used to transport liquids, gases, and certain bulk materials.
It may be suitable for:
Chemicals
Food-grade liquids
Oils
Fuel
Liquid raw materials
Some types of gas
Tank containers must meet strict safety and handling requirements, especially for hazardous cargo.
What Is a Platform Container?
A platform container mainly consists of a reinforced floor without full side walls or a roof.
It is used for very large or heavy cargo that cannot fit inside a standard container.
Examples include:
Project cargo
Industrial equipment
Large machine parts
Heavy steel products
Oversized structures
Transport planning may require cranes, special permits, and route analysis.
What Is a Ventilated Container?
A ventilated container allows natural airflow through the cargo area.
It is used for products that may be damaged by moisture or condensation.
Typical cargo includes:
Coffee beans
Cocoa
Agricultural products
Dry food products
Moisture-sensitive goods
Ventilation can help reduce humidity inside the container.
What Is an Insulated Container?
An insulated container helps protect cargo from rapid temperature changes.
Unlike a reefer container, it may not actively cool the cargo.
It can be used for goods that require more stable conditions during short or moderate transport periods.
Container Type Comparison
Cargo Type | Suitable Container |
Standard packaged goods | Dry container |
Heavy and dense cargo | 20-foot dry container |
Lightweight and bulky cargo | 40-foot high cube |
Temperature-sensitive cargo | Reefer container |
Tall cargo | Open top container |
Wide or heavy machinery | Flat rack container |
Liquid cargo | Tank container |
Moisture-sensitive products | Ventilated container |
Oversized project cargo | Platform container |
The final choice should depend on cargo dimensions, weight, packaging, and carrier requirements.
How to Choose the Right Shipping Container
Before selecting a container, businesses should prepare the following information:
Cargo length
Cargo width
Cargo height
Total weight
Number of packages
Pallet quantity
Product type
Temperature requirements
Loading method
Unloading method
Hazardous cargo status
Ventilation requirements
Stacking limitations
Incorrect cargo measurements may result in additional charges or loading delays.
20-Foot vs 40-Foot Container
The choice between a 20-foot and 40-foot container depends on both volume and weight.
A 20-foot container may be better for heavy and dense products.
A 40-foot or high cube container may be more suitable for lightweight but bulky goods.
Businesses should compare:
Total cargo volume
Total weight
Freight rate
Port charges
Loading conditions
Cargo stacking
Inland transport costs
A freight forwarder can provide quotations for both options.
Standard Container vs High Cube
The main difference is height.
High cube containers provide more internal volume and may be useful for cargo that is too tall or bulky for a standard container.
However, a high cube container may not always be necessary. Using a larger container without a clear need may increase costs.
Container Selection and FCL Shipping
In FCL shipping, one company reserves the entire container.
The container may be completely full or partially filled.
The selected container should match:
Cargo dimensions
Cargo weight
Loading equipment
Product sensitivity
Delivery requirements
Container Selection and LCL Shipping
In LCL shipping, different companies share the same container.
The shipper may not select the full container type directly, but product information remains important.
LCL cargo should be:
Strongly packaged
Clearly labeled
Properly palletized
Protected from moisture
Suitable for shared container transport
Container Types and Demurrage Charges
Special containers may have higher demurrage and detention charges.
This may include:
Reefer containers
Open top containers
Flat rack containers
Tank containers
These containers may also have limited availability.
Businesses should confirm:
Free time
Daily delay charges
Return conditions
Empty-container return location
Equipment availability
before booking.
Common Container Selection Mistakes
Businesses should avoid:
Providing incorrect cargo dimensions
Ignoring weight limits
Choosing only based on price
Using a dry container for temperature-sensitive goods
Failing to plan crane loading
Ignoring cargo securing requirements
Booking special equipment too late
Not checking destination unloading conditions
How Can a Freight Forwarder Help?
A freight forwarder can help evaluate:
Cargo type
Dimensions
Weight
Route
Loading method
Delivery requirements
Container availability
Freight cost
Special equipment needs
They may also coordinate booking, documentation, inland transport, tracking, and final delivery.
