- Bulk consumer electronics and appliances
- Automotive parts and vehicles
- Agricultural and food products in dry bulk
A 40ft shipping container is often the most cost-effective choice for businesses shipping large quantities of goods, as it optimizes transportation costs per cubic meter.
Types of 40ft Containers and Their Uses
Different 40ft container types cater to various shipping needs, especially for oversized, heavy, or temperature-sensitive cargo. Below are the most common types:
40ft General Container
- Standard dry container for general cargo transport.
- Used for high-volume shipments such as furniture, electronics, textiles, and machinery.

Choosing the right 40ft container type ensures the safe, cost-efficient transportation of your cargo while meeting specific shipping requirements.
40ft High Cube (HC) Container: Size and Capacity
A 40ft High Cube (HC) container is similar to a standard 40ft container but has an extra 30cm (1ft) in height. This additional space makes it ideal for lightweight, voluminous cargo that requires more vertical room.

The 40ft HC container is a preferred choice for shippers looking to maximize storage capacity while keeping freight costs competitive.
What Are High Cube Containers Used For?
High Cube (HC) containers are designed to provide extra vertical space, making them ideal for shipments requiring additional height clearance. Compared to standard containers, HC containers offer more volume without increasing the footprint, making them highly versatile across industries.

With efficient space utilization, cost-effectiveness, and versatility, High Cube containers are widely used in global trade, logistics, and custom container projects.
How Many Pallets Can a Container Hold?
The number of pallets that fit inside a shipping container depends on pallet size, loading method, and whether pallets are stackable. Below is a general guide for standard pallets (1.2m x 1m) and Euro pallets (1.2m x 0.8m).
Pallet Capacity by Container Type
| Container Type | Standard Pallets (1.2m x 1m) | Euro Pallets (1.2m x 0.8m) |
|---|---|---|
| 20ft Container | 10–11 pallets | 11–12 pallets |
| 40ft Container | 20–21 pallets | 23–24 pallets |
| 40ft High Cube | 21–22 pallets | 24–26 pallets |
Factors Affecting Pallet Loading
- Stackable vs. Non-Stackable Pallets – Stacking pallets doubles capacity, but only applies to non-fragile items.
- Weight Restrictions – Each container has a maximum payload, so heavier goods may reduce pallet count.
- Loading Method – “Turned” (sideways) pallet loading increases space efficiency but may not be suitable for all goods.
💡 Optimizing pallet arrangement helps maximize space while ensuring safe cargo transport.
How to Maximize Cargo Space in a Container?
Efficiently utilizing space in a shipping container reduces freight costs and ensures cargo is transported securely. Below are key strategies to maximize cargo capacity:
Choose the Right Container
- High Cube Containers – Best for voluminous and lightweight cargo due to extra height.
- Flat Rack Containers – Ideal for oversized machinery and irregular-shaped items.
Optimize Cargo Arrangement
- Stack Cargo Securely – Use reinforced stacking for sturdy items to fully utilize vertical space.
- Use Uniform Packaging – Standardized boxes, crates, or cartons improve stacking efficiency.
- Align Cargo Along Walls – Placing cargo against container walls minimizes wasted space in the center.
Pallet Selection & Packing Techniques
- Euro Pallets for 40ft HC Containers – Euro pallets fit more efficiently in high cube containers.
- Use Vacuum Packing for Soft Goods – Reduces volume for textiles, bedding, and foam products.
- Double-Stacking Where Possible – Only for non-fragile and lightweight goods.
💡 Efficient packing not only maximizes cargo space but also reduces the number of containers needed, cutting transportation costs.
