Kosipo is harvested in forests in the southern and eastern regions of Cameroon. The maximum height of kosipo trees is 55 m with a trunk diameter of up to 2.5 m. The trunk is usually straight and cylindrical and may have root flares.
Sawn kosipo is brown to dark red brown and therefore darker than sipo. The sapwood is always clearly identifiable and can be up to 50 mm thick. Kosipo wood has a predominantly medium coarse texture. It is difficult to easy to work, but very often blunts cutting tools. Pre-drilling is recommended. Surface treatments are possible but often require pre-treatments and slow drying.
Kosipo is often used as a substitute for sipo and sapele, but is also used to produce façades, furniture, stairs and parquet floors as well as in yacht building and shipbuilding.
