Cumaru –(Dipteryx Odorata spp.)

Commonly known in the marketplace, both Red and Yellow varieties are mixed together, upon special request we can color sort. Other common names include Brazilian Teak, Tonka Bean, Rumara, or Charapilla. It is a wood that is comparable in density and janka hardness to Ipe but is only slightly less stable. Our cumaru is kiln dried (KD) to promote stability and is also available in FSC or Non-FSC certifications; readily available as decking, flooring, dimensional lumber, E4E, S4S, RS (Rough Sawn), deck tiles, and table slabs.
