Walnut varies naturally by region, log and the proportion of sapwood to heartwood. Our custom sort program lets you specify color, tone and sapwood tolerance so every load matches the last. #### Does Walnut lighten over time? Yes — Walnut is unusual in that it mellows rather than darkens. UV exposure softens the deep chocolate heartwood toward a warmer amber-brown and reduces contrast with the sapwood. A UV-inhibiting finish slows it. #### Is Walnut suitable for export projects? Yes. American Black Walnut is among the most requested US hardwoods internationally. Bennett ships kiln-dried Walnut worldwide with EUDR-ready traceability, phytosanitary certification and ISPM-15 compliant packaging. ## Ready to Order?
