These are Hapag-Lloyd's published example specifications, retrieved 2026-10-12. Hapag-Lloyd notes that figures vary by manufacturer, so a box from another owner, or another build year, can differ by a few centimeters and a few hundred kilograms. For a tight fit, ask the carrier for the specification of the equipment it will supply.
Maximum payload is what the container itself is rated to carry. Check the road, rail and port weight limits on your route as well.
The drawings are to scale from the inside dimensions; the walls, doors and fittings around them are illustrative. Imperial values are converted with the exact factors 1 inch = 25.4 mm and 1 pound = 0.453 592 37 kg, and rounded to the nearest eighth of an inch, pound or cubic foot, so they can differ slightly from the rounding on Hapag-Lloyd's pages.
