Market Value & Sustainability

Estimated Market Value

Ranges from $12.00 to $20.00 per board foot for 4/4 select grade lumber.

Wood Age Estimate

Modern cut (within the last 10-20 years) based on the surface texture and visible machine-planing marks.

Sustainability Status

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

Workability

Excellent workability with both machine and hand tools; it planes, glues, and nails well, though it can occasionally exhibit tearout in figured boards.

Notable Features

Distinctive mild, spicy scent when being worked; known for its stability and relatively lightweight strength ratio compared to other hardwoods.

Finish Recommendations

Best suited for penetrating oils (tung or linseed), shellac, or polyurethane finishes to highlight deep colors and luster.

Identification Confidence

High: The wood displays the classic chocolate-brown heartwood color, semi-ring-porous structure, and grain characteristics specific to North American Black Walnut.
