Iroko Lumber Prices — 2026 Buying Guide

Milicia excelsa  ·  Exotic Hardwood  ·  Janka 1260

Iroko (Milicia excelsa) has emerged as the premier alternative to genuine teak, offering nearly identical durability and weather resistance at roughly half the cost. Professional boatbuilders and high-end outdoor furniture makers prize its golden-brown heartwood and exceptional stability, while kitchen designers increasingly specify it for waterfront homes where moisture resistance matters most. With teak becoming increasingly restricted and expensive, iroko represents the sweet spot between performance and price for projects demanding long-term exterior exposure. The species carries just one significant caveat: its sawdust and oils can trigger contact dermatitis in sensitive individuals, making proper respiratory protection essential during machining.

About Iroko

Iroko grows throughout tropical West and Central Africa, from Senegal to Uganda, with the largest commercial stands concentrated in Ghana, Nigeria, and Cameroon. The trees reach impressive dimensions of 150 feet tall with trunk diameters exceeding 8 feet, making them among Africa’s most valuable timber exports for over a century. Commercial logging focuses on mature trees from natural forests, as plantation cultivation remains limited despite growing demand.

Fresh-sawn iroko heartwood displays a rich golden yellow that deepens to warm brown with age and UV exposure, while the narrow sapwood appears pale yellow and gets excluded from premium grades. The grain runs straight to slightly interlocked with a medium to coarse texture that machines to a naturally lustrous surface without additional polishing. Distinctive yellow mineral deposits occasionally streak through boards, creating unique character marks that some buyers prize while others consider defects. Quarter-sawn material reveals subtle ray fleck similar to oak but more subdued.

While commonly called African teak, iroko belongs to an entirely different botanical family yet delivers comparable marine performance at 60 percent of genuine teak prices without CITES permit complications. Its 1260 Janka rating falls between genuine teak at 1155 and white oak at 1360, providing the perfect balance of workability and durability that made teak famous. Unlike teak, iroko lacks the oily feel and distinctive odor, making it more pleasant for indoor applications while maintaining the weather resistance that outdoor projects demand. Cedar and mahogany cost less but cannot match iroko weathering performance over decades of exposure.

European shipbuilders discovered iroko in the early 1900s as teak supplies tightened, leading to its adoption for yacht decking and marine trim where it earned the nickname poor man teak. Post-war reconstruction efforts in Europe drove massive iroko imports for window frames and exterior joinery, establishing quality standards that persist today. Contemporary high-end resort developments throughout the Caribbean and Mediterranean specify iroko for poolside decking and outdoor kitchens, where its combination of beauty and longevity justifies the premium over pressure-treated alternatives.

What Iroko Costs in 2026

Rising prices reflect tightening West African export quotas as governments balance timber revenues against international pressure for forest conservation, with Ghana implementing new 20 percent harvest reductions starting in 2025. This upward trend will likely persist through 2027 as alternative species like sapele and utile face similar restrictions, forcing buyers toward the limited supplies of legally certified material. Purchase now for projects planned within 18 months, as current inventory levels suggest 15-25 percent price increases before supplies stabilize.

Key Price Drivers

• African political instability and export restrictions drive supply volatility — Ghana and Nigeria periodically halt logging permits for forest management, creating sudden shortages that can double prices within months
• Marine industry growth fuels premium demand as yacht builders and dock contractors compete with furniture makers for the best grades, pushing clear heartwood prices higher while leaving defect grades relatively stable
• Teak CITES restrictions force high-end projects toward iroko as architects specify legally compliant alternatives, creating artificial demand spikes when major resort or marina developments launch simultaneously
• Currency fluctuations in West African countries directly impact export prices — recent devaluations made iroko temporarily cheaper, but stabilization efforts will reverse these gains through 2026
• Shipping container costs from West Africa remain elevated compared to pre-2020 levels, with iroko suffering disproportionately because its weight and bulk make air freight economically impossible for all but specialty cuts
• FSC certification requirements from major retailers and government projects create a two-tier market where certified iroko commands 25-40 percent premiums over conventional material, but supplies remain extremely limited

Working Properties & Finishing

Machining

Use carbide-tipped blades with 40 teeth for ripping and 80 teeth for crosscuts, as iroko contains silica deposits that dull high-speed steel quickly and create chip-out with insufficient teeth. Feed rates should stay moderate because rushing creates burning along cut edges that requires extensive sanding to remove, while the natural oils can gum up blades during extended milling sessions. Router bits need frequent cleaning with mineral spirits to prevent resin buildup that causes burning and poor surface finish. Always use dust collection and wear respiratory protection, as the fine particles can trigger allergic reactions even in woodworkers who typically work without masks.

Joinery & Assembly

Iroko glues reliably with both PVA and polyurethane adhesives, but wipe joint surfaces with acetone immediately before assembly to remove surface oils that can weaken bond strength. Pre-drill all screw holes within 2 inches of board ends, as the interlocked grain can cause splitting even with self-drilling screws in this naturally brittle species. Mortise and tenon joints perform exceptionally well due to iroko stability, but cut mortises 1/32 inch deeper than standard to accommodate the species tendency to compress slightly under clamping pressure.

Finishing

Iroko accepts stain unevenly without proper preparation — always use a pre-stain wood conditioner or thin coat of diluted shellac to prevent blotching, especially on plain-sawn boards where grain density varies significantly. The species responds best to oil-based finishes like Watco Danish Oil or marine-grade varnishes, as water-based products can raise grain and create a muddy appearance over the naturally golden wood. Tannins rarely cause problems with oil finishes, but water-based stains can react with mineral deposits to create gray streaks that resist sanding. Expect the golden color to deepen considerably in the first six months of UV exposure, then stabilize to a rich brown similar to aged teak. For outdoor applications, I recommend Epifanes Clear Varnish applied in three thin coats after proper surface preparation.

Before You Buy — What to Know

Always request to see the actual boards before finalizing purchase, as iroko grades vary dramatically between suppliers and what passes for FAS in some imports would barely qualify as Select in domestic hardwoods. Ask specifically about kiln-drying schedules, since air-dried iroko often harbors moisture pockets that cause checking months after installation, and verify the lumber has been properly stickered during transport to prevent staining. Inspect board ends carefully for ring shake and other defects that sellers sometimes hide with end-sealing wax, and avoid any stock showing white sapwood streaks unless you plan to machine them out completely. Check for insect damage, particularly small round holes that indicate powder post beetles survived the import process.
