Utile / Sipo (Entandrophragma utile) Hardwood

Yes — Utile and Sipo are different trade names for the same species: Entandrophragma utile. In the UK and Europe, 'Utile' is more common; in North America and marine markets, 'Sipo' is often used. 'Sipo Mahogany' is another trade name.

Both are in the same genus (Entandrophragma) but are different species. Utile has a more uniform, mahogany-like grain with less dramatic figure than Sapele's ribbon-stripe. Sapele is harder (1,410 vs 1,240 lbf) and slightly more durable. Utile is preferred when a Genuine Mahogany look is desired; Sapele when a more dramatic figure is wanted.

Utile is harder (1,240 vs 800 lbf), more durable (Class 2 vs Class 2-3), and more affordable than Genuine Mahogany. It is the closest visual match among African species and is widely used as a premium substitute in applications where true Swietenia is either unavailable or cost-prohibitive.

Yes — Utile's Class 2 durability makes it suitable for exterior joinery, marine trim, and covered outdoor applications. It is widely used in Europe for exterior windows and doors. For fully exposed decking, denser species provide better long-term performance.

Utile (Entandrophragma utile) is classified as Vulnerable by IUCN but is not CITES-listed. It is harvested from managed forests in Central and West Africa. We source only legally documented material from responsible suppliers.
