A 40 GP container is a 40-foot General Purpose shipping container used for dry cargo transportation worldwide.
A 40 GP container, also known as a 40-foot General Purpose dry container, is one of the most widely used shipping containers in global logistics. With a standard length of 40 feet, it offers nearly double the capacity of a 20ft container while maintaining the same width and height as other standard dry containers.
Designed for non-refrigerated, general cargo, the 40 GP is the backbone of international sea freight, rail transport, and road logistics. Its standardized ISO design ensures it can be seamlessly handled across ships, ports, trucks, and trains anywhere in the world.
In the shipping industry, "40 GP" is a common abbreviation used by freight forwarders, shipping lines, and logistics professionals.
40 = 40-foot length
GP = General Purpose (also called "Dry" or "Standard" container)
You will frequently see it written as "1 x 40GP", "2 x 40GP containers", or simply "40GP" in quotes, booking confirmations, and shipping documents. This shorthand makes communication fast and clear in international trade.
Understanding the exact 40 GP container dimensions is essential for accurate cargo planning.
Here are the standard specifications for a typical 40ft GP container:
| Item | Imperial | Metric |
|---|---|---|
| External Dimensions | 40’ x 8’ x 8’6” | 12.192m x 2.438m x 2.591m |
| Internal Dimensions | 39’5” x 7’8” x 7’10” | 12.032m x 2.352m x 2.393m |
| Door Opening (W x H) | 7’8” x 7’6” | 2.340m x 2.280m |
| Internal Volume | Approx. 2,350 – 2,390 cu ft | 67.0 – 67.7 m³ |
| Tare Weight (Empty) | Approx. 8,000 – 8,800 lbs | 3,650 – 4,000 kg |
| Maximum Payload | Approx. 58,000 – 59,000 lbs | 26,500 – 26,800 kg |
| Maximum Gross Weight | 67,200 lbs | 30,480 kg |
The 40 ft container size provides almost twice the volume of a 20ft GP, making it highly efficient for larger shipments.
One of the most common questions is how the standard 40 GP compares with the High Cube version.
| Type | External Height | Internal Height | Best For |
|---|---|---|---|
| 40 GP | 8’6” (2.591m) | 7’10” (2.393m) | Standard density cargo |
| 40 HC | 9’6” (2.896m) | 8’10” (2.698m) | Bulky, lightweight, high-volume cargo |
The main difference between 40GP vs 40HC lies in height. The 40 GP offers standard height and is ideal for most general cargo, while the 40 HC container provides one extra foot of height, delivering about 10–12% more volume for items that are tall or low in density.
The 40 GP container is incredibly versatile across many industries.
General Cargo ShippingIt is the preferred choice for transporting electronics, textiles, machinery, auto parts, consumer goods, chemicals, and packaged products. Its large capacity helps reduce shipping costs per unit on medium to large volume shipments.
Warehouse StorageBusinesses use 40ft GP containers for secure, weatherproof temporary or long-term storage on construction sites, factories, ports, and distribution centers.
Container ConversionMany companies convert 40 GP containers into:
Portable offices and site cabins
Workshops or mobile retail units
Storage rooms or small warehouses
Here’s why the 40 GP remains a top choice for shippers worldwide:
Large cargo capacity — Nearly double the space of a 20ft container
Lower shipping cost per unit — More efficient for bulk or medium-large shipments
Global availability — The most common container size in the world
Durable steel structure — Built with high-strength Corten steel for long service life
Ideal for international trade — Perfectly suited for sea, rail, and road multimodal transport
A frequently asked question is pallet capacity.
In a standard 40 GP container, you can typically fit:
20–21 standard pallets (48” x 40”) in a single floor layer
Up to 24–26 Euro pallets depending on arrangement
The exact number depends on pallet size, cargo stacking method, and whether you use double stacking for lighter goods. Proper loading planning can maximize every cubic meter.
| Your Need | Best Choice | Reason |
|---|---|---|
| Small shipments or tight space | 20 GP | Easier to handle and more flexible |
| Bulk cargo or larger volumes | 40 GP | Better economy and lower cost per unit |
| Want to minimize freight cost | 40 GP | More cargo per container |
For most international traders moving meaningful volumes, the 40 GP delivers superior cost efficiency.
