20' High Cube
A 20 ft box with a foot of extra headroom (ISO size code 1CCC), sharing the same footprint and corner-casting geometry as the standard 20 ft unit — every twistlock, lashing point and lifting fitting engages it identically; only the height differs.

Governed by ISO 668 size code 1CCC (series-1 external dimensions) and ISO 1496-1 (dry freight containers). Figures come from HZ Containers' 20 ft high-cube specification pages, cross-checked between two published sheets after a third figure — a 2 280 mm door height — turned out to be the standard 20 ft value carried over in error. Internal dimensions match the 20 ft General Purpose in length and width, with 296 mm of extra height against a 305 mm external step. Drawn from a single publisher, so tare in particular varies by builder — confirm against the CSC plate.
