Product Sources
Shorea genus is a major timber source in international trade. They are plentiful, and supplies are universally available, especially in the form of veneers. This popular wood is typically priced in the inexpensive range.

Many species in the Shorea genera are also a source of other economically important non-timber products. Seeds of some species yield fat which is used in the manufacture of chocolate. Others produce nuts, the most common of which is the illipe nuts of commerce produced by S. gysbertisiana . The nuts yield a fat which is similar to cocoa-butter in some of its properties. Shorea trees are also tapped for oleo-resin, and typical dammar is obtained from S. wiesneri which grows in Java and Sumatra. The tree of S. robusta produces dammar which is used as a disinfectant and as incense in religious ceremonies in India. Other non-timber products from Shorea are reported to include tannin and fibers.
