Export potential is rated as fair. Espave is rather abundant and grows on accessible terrain which makes it easy to harvest. It is, however, not very prominent on the world market because it has uses that compete with the less expensive and more abundant Lauan (Shorea spp). Its properties are less desirable than other woods for cabinet making. The tree of Espave is also the source of various non-timber products. It produces edible apples and nuts, and the macerated bark is used as a type of fish poison in Panama.
