Product Sources
The ITTO reports that this species is frequent source of timber which is exported in low quantities and only occasionally.
African padauk is available in both lumber and veneer forms on the market in North America, but prices are typically in the high range.
Availability in long lengths, wide boards, and in veneer form is rather limited on the European market, but prices are comparable to that of the lower cost hardwoods.
