A new 20GP quotes in the range of $2,000 to $2,500 ex-works China. The price is rarely the hard part of buying one. The production slot is: August plans across the network ran about 94% 40HC and about 5% 20GP, so 20-footers are effectively built to order on a roughly ten-week cycle. Current figures are in the monthly market report.
$2,000 to $2,500 ex-works for a standard-spec new 20GP, ISO type 22G1, with the usual movement inside the range for steel cost, batch size, paint and spec extras. A 20FT High Cube sits above that range because it is a shorter production run of a taller shell.
Ex-works means the box in the factory yard. Nothing about moving it is included, and for a 20-footer the moving cost is proportionally heavier than for a 40HC, because a slot on a vessel is not priced by the cubic metre.
World container demand is overwhelmingly for 40HC. Carriers order it, lessors order it, and factory lines are configured and scheduled around it. A 20GP run means changing over a line that would otherwise be producing the volume product, so plants schedule 20-footers in blocks rather than continuously.
The practical consequence for a buyer is that a 20ft order is quoted against a production month, not against stock. Asking for units next week is asking for something the schedule does not contain.
A 20GP has two end frames, two side walls, a roof, a floor and a door set, exactly as a 40HC does. It has roughly half the enclosed volume but nothing close to half the components, half the welding or half the survey work. That is the structural reason its price per cubic metre is higher, and it is why comparing a 20ft quotation to half a 40ft quotation always looks unfavourable.
Depot surplus exists in the sizes carriers reposition, and that is overwhelmingly the 40HC. 20-footers move on trades that consume them locally, so they do not accumulate as surplus in the same way. When they do appear in a depot they are usually older units at cargo-worthy grade rather than one-trip condition.
For most buyers this makes factory production with first-trip delivery the realistic route for 20FT equipment, and US depot stock the realistic route for standard 40HCs.
