Market Value & Sustainability

Estimated Market Value

$10.00 - $18.00 per board foot depending on width and grade

Wood Age Estimate

Freshly cut or recently milled (less than 1 year); shows rough saw marks, pencil layout lines for turning, and minimal oxidation on the surface

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; generally considered sustainable and widely available in North America

Workability

Excellent; works easily with both hand and machine tools. Planes and sands well. Glues and finishes very well, though it has a faint distinct odor when being worked

Notable Features

Mild, pleasant characteristic odor when worked; contains juglone which can be a mild allergen to some; known for exceptional dimensional stability once seasoned

Finish Recommendations

Responds excellently to oil-based finishes (tung or linseed) to enhance depth; clear polyurethane or lacquer for protection; avoid heavy stains to preserve natural color

Identification Confidence

High; the distinctive color contrast between the pale sapwood and the developing heartwood tones, combined with the grain pore structure and bark texture visible on the edge, is characteristic of North American Black Walnut
