Artocarpus dadah is a fairly important source of keledang timber; the wood is used especially for poles, bridges and flooring. The latex is reported to have purifying properties when applied to wounds. The fruit is edible but sour.

A medium-sized to fairly large deciduous tree up to 35 m tall, bole up to 100 cm in diameter; leaves obovate-oblong to ovate-elliptical, base rounded, entire, the veins puberulent above, densely to sparsely pubescent below, with 10—20 pairs of secondary veins, stipules not amplexicaul; male head globose or pulvinate, 8—15 mm across; styles in female head simple; syncarp subglobose, to c. 5 cm across, with an almost smooth surface, velutinous. Artocarpus dadah occurs in evergreen and deciduous forest but also in open country, up to 1000 m altitude. The wood is reported to be durable, resistant to insect attack and to alternating wet and dry conditions. The density is 650—880 kg/m³ at 15% moisture content.
