Kabukalli

A strong, reliable Guyanese hardwood valued for durability, stability, and all‑purpose performance.

Common Name(s): Kabukalli, Kabukali, South American Locust‑type hardwood

Scientific Name: Goupia glabra

Distribution: Guyana, Suriname, Northern Brazil, Eastern Amazon Basin

Kabukalli is a durable, medium‑to‑high density hardwood native to Guyana and the eastern Amazon region. Known for its strength, stability, and resistance to decay, Kabukalli is widely used in flooring, furniture, cabinetry, and general construction. Its warm brown coloration, fine texture, and consistent grain make it a versatile species suitable for both interior and exterior applications. Kabukalli offers a dependable balance of workability and performance, making it a preferred choice for craftsmen seeking a strong, stable hardwood without the extreme density of heavier species.
