Market Value & Sustainability

Estimated Market Value

Approximately $12.00 - $18.00 per board foot depending on grade and region.

Wood Age Estimate

Modern; the crisp laser engraving and contemporary finish suggest the wood was processed and finished within the last 5-10 years.

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable within its native range.

Workability

Easy to work with both hand and machine tools. It planes smoothly, glues and finishes well, although it has a faint, characteristic odor while being worked.

Notable Features

Distinctive mild spicy scent when worked; contains juglone which can be a mild irritant; highly prized for its exceptional finishing qualities and dimensional stability.

Finish Recommendations

Clear coats such as Danish oil, polyurethane, or lacquer are best to highlight the natural deep brown tones and grain depth.

Identification Confidence

High; the characteristic chocolate-brown color, pore structure, and grain cathedral patterns are archetypal for Black Walnut.
