Native to Asia, Koompassia malaccensis are tall deciduous trees that can reach heights of 40 metres tall with a trunk diameter of 1-1.5 metres.

Its wood, commonly called Kempas, is among the most beautiful and unique hardwoods in the world. Its heartwood ranges from orange-red to reddish-brown with subtly contrasting yellow to pale white tones and darkens with time.

Kempas is a hard, heavy wood, with a rather coarse texture and a spiralled grain. It is fairly lustrous and has a good glossy wood performance.
