Eastern North America

Market Value & Sustainability

Estimated Market Value

$8.00 - $15.00 per board foot depending on grade and width.

Wood Age Estimate

Fresh cut (under 1 year) based on the bright color of the sapwood and the sharp, unoxidized radial cracks.

Sustainability Status

Not listed on CITES Appendices or the IUCN Red List; widely available and sustainable.

Workability

Excellent workability with both hand and machine tools; glues, stains, and finishes extremely well, though it can elicit allergic reactions in some.

Notable Features

Distinctive mild spicy scent when cut; contains juglone which can be a mild irritant; excellent dimensional stability.

Finish Recommendations

Denatured alcohol to test color, followed by Danish oil or polyurethane to highlight the contrast between heartwood and sapwood.

Identification Confidence

High; the bark texture, the specific ratio of sapwood to heartwood, and the circular pith are characteristic of a young Black Walnut limb/trunk.
