D. caudiferus is a common lowland keruing in Borneo and occurs on clay soils in mixed dipterocarp forest on undulating land and hillsides below 800 m altitude. The density of the wood is 510-865 kg/m3at 15% moisture content. The wood is considered poorly resistant to fungal decay, but not difficult to impregnate. See also the table on wood properties.
