Interior Dimensions: 19’4″ long x 7’8″ wide x 7’10” high
Capacity: 1,172 cubic feet
Maximum Payload: 61,289 lbs
40-foot containers
Exterior Dimensions: 40′ long x 8′ wide x 8’6″ high
Interior Dimensions: 39’6″ long x 7’8″ wide x 7’10” high
Capacity: 2,390 cubic feet
Maximum Payload: 57,759 lbs
The 40-foot high cube variant adds an extra foot of height (9’6″ exterior) for an interior capacity of 2,694 cubic feet. This is ideal for lightweight, voluminous cargo.
When selecting a size, consider:
Cargo Volume
Ensure the container’s interior dimensions can accommodate your cargo quantity, accounting for any specialized packaging or dunnage required.
Cargo Weight
Your loaded container must not exceed the maximum payload, which factors in the container’s tare weight. Verify your cargo density is compatible with the container’s capacity.

Choosing the optimal container type based on your cargo’s unique characteristics and handling needs is key to ensuring safe, on-time, cost-effective delivery.
What should you know about container condition and age?
A container’s physical condition and age significantly impact its protective capabilities and suitability for your cargo. When assessing container condition, key factors to consider include:
Structural Integrity
Inspect the container for any dents, cracks, or holes in the walls, roof, and floor that could compromise weather-tightness or allow entry of moisture, pests, or contaminants. Ensure doors and hardware are in proper working condition.
Cleanliness
Check that the container is clean, dry, and free from dirt, debris, and residue from previous cargo to avoid contamination. Look for any signs of rust or corrosion that could indicate compromised structural integrity.
Weatherproofing
Verify that door seals are intact and effective at preventing water and moisture intrusion. Confirm that the container is watertight by inspecting for daylight visible through gaps or holes.
Odors
Note any unusual or strong odors that could indicate improper cleaning after transporting odorous cargo or the presence of mold or other contaminants.
Age also plays a role in container selection:
Newer Containers (0-3 years)
Typically in the best structural condition with minimal wear and tear. Ideal for sensitive, high-value, or perishable goods requiring maximum protection.
Mid-Age Containers (3-12 years)
Most common and readily available. Suitable for most standard cargo types when in good repair and properly maintained.
Older Containers (12-25+ years)
More likely to have structural issues or reduced water-tightness. Best limited to rugged, non-sensitive goods unless thoroughly inspected and refurbished.
Carefully evaluating container condition and age against your cargo’s fragility, value, and sensitivity to external factors is critical for selecting a container that will safely and reliably protect your goods throughout their journey.
How do you balance size, type, and condition when choosing a container?
