Though used in limited quantities in Bangladesh, Okan wood is imported from African countries and is known as an extremely strong and durable timber. Okan wood ranges from dark brown to reddish brown, with fine to medium texture and dense, straight grain — making it suitable for heavy timber structures, furniture, flooring, wood paneling, and specialized construction. Its durable, long-lasting properties give it a high value in the international market.
