Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
10.00 to 18.00 USD per board foot depending on thickness and grade.
Wood Age Estimate
5-15 years based on modern cabinetry construction, contemporary hardware, and lack of deep oxidation or heavy patina.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List of Threatened Species; generally sustainable with FSC availability.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes well, though large knots can cause occasional tearout.
Notable Features
Distinctive mild, sweet odor when worked; contains juglone which can be an irritant; prized for its dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes or clear lacquers are recommended to enhance the natural dark tones; water-based topcoats may appear slightly cold on this species.
Identification Confidence
High; the rich brown color palette, specific 'cathedral' grain arching, and texture are classic hallmarks of North American Black Walnut used in cabinetry.
