Common uses: Baskets, Bedroom suites, Boat building (general), Boat building: decking, Boat building: framing, Building materials, Cabinetmaking, Chairs, Chests, Concealed parts (Furniture), Cooperages, Decks, Decorative veneer, Desks, Dining-room furniture, Domestic flooring, Door, Dowell pins, Dowells, Drawer sides, Excelsior, Factory flooring, Figured veneer, Fine furniture, Floor lamps, Flooring, Food containers, Furniture , Furniture components, Furniture squares or stock, Furniture, Hatracks, Heavy construction, Joinery, Kitchen cabinets, Light construction, Living-room suites, Marine construction, Office furniture, Paneling, Parquet flooring, Planks, Plywood, Poles, Radio - stereo - TV cabinets, Roofing, Rustic furniture, Shipbuilding, Stools, Structural work, Sub-flooring, Tables , Tables, Utility furniture, Vats, Vehicle parts, Veneer, Veneer: decorative, Wardrobes Product sources: White peroba has once enjoyed the position as the most popular timber tree of the Rio de Janeiro area for fine furniture and interior trim, but it is now almost extinct. Environment profile: Data source is Nature Conservancy
The species is critically imperiled globally because of extreme rarity or because of some factor or factors that render it especially vulnerable to extinction. White peroba occurs in very small numbers globally (typically 21 or fewer occurences), and there are very few remaining individual trees or acres of trees

It has superior properties in compression parallel to grain in the air-dry condition than Teak, White oak, or Hard maple. It is fairly hard, resisting wear, denting, and marring fairly well Berni, C.A., Bolza, E., Christensen, F.J.,1979,South American Timbers - The Characteristics, Properties and Uses of 190,Species,C.S.I.R.O Div.
