What Is Log Grading?
Log grading is the process of assessing the quality of individual logs based on visible defects (knots, splits, rot, sweep), diameter, length, and species. A trained grader examines each log and assigns a grade that reflects how much usable lumber it will produce and what that lumber is worth. The most widely recognized system in the eastern U.S. is the NHLA (National Hardwood Lumber Association) standard.
The price difference between grades is enormous — a veneer-grade white oak log can sell for 5× more than a pallet-grade log of the same species. Without accurate grading, sellers routinely leave significant money on the table.
NHLA Log Grades at a Glance
Highest quality. Virtually defect-free faces suitable for slicing into veneer sheets. Commands top-dollar prices at veneer mills.
Premium sawlog. Requires 83.3% clear cuttings from the worst face. Produces high-yield, defect-free lumber for furniture and export.
General sawlog. Requires 66.7% clear cuttings. Used for quality cabinetry, furniture components, and flooring.
Lower grade. Requires 50% clear cuttings. Suitable for pallets, railroad ties, crating, and general construction lumber.
What to Expect from a Log Grading Service
Hiring a professional log grader is straightforward. Here’s what the process typically looks like:
Contact a grading provider and arrange a visit. Most graders serve a multi-county area and can come to your log yard, landing, or woodlot.
The grader inspects each log, checking for defects on all visible faces, measuring diameter (inside bark) at the small end, and recording length.
Each log is assigned a grade (veneer, FAS, #1 Common, #2 Common, or pallet/tie) using NHLA standards. Board-foot volume is calculated using standard log rules (Doyle, Scribner, or International).
You receive a written tally showing each log’s species, dimensions, grade, and estimated value at current market prices.
A good grader will advise on how to sort and market your logs for maximum return — for example, selling veneer-grade walnut separately instead of mixing it with sawlogs.
Typical Pricing for Log Grading
Professional log grading is one of the most cost-effective services in the timber industry.
In nearly every case, professional grading pays for itself. Identifying even a handful of veneer-grade logs in a load that would otherwise sell at sawlog prices can add hundreds or thousands of dollars to your total sale price.
Common Questions
What is log grading?
Log grading is the process of evaluating a log’s quality based on visible defects, diameter, length, and species. Professional graders assess each log to assign a grade that reflects its potential lumber yield and value. The most widely used system in the eastern United States is the NHLA (National Hardwood Lumber Association) grading standard.
Why does log grading matter for pricing?
Log grade is the single biggest factor in pricing. A veneer-grade white oak log can sell for 5 times more than a pallet-grade log of the same species. Without accurate grading, sellers often leave money on the table by accepting blanket pricing, and buyers risk overpaying for lower-quality wood. Professional grading ensures both parties get a fair deal based on actual log quality.
What are the NHLA hardwood lumber grades?
The main NHLA grades are FAS (First and Seconds), #1 Common, and #2 Common. FAS is the highest grade, requiring 83.3% clear cuttings from the worst face — these logs produce the most defect-free lumber and command premium prices. #1 Common requires 66.7% clear cuttings and is used for quality furniture and cabinetry. #2 Common requires 50% clear cuttings and is suitable for flooring, paneling, and general construction. Veneer-grade logs exceed FAS standards and are the most valuable.
How much does professional log grading cost?
Professional log grading typically costs $100–$300 per day, or $0.50–$1.50 per log for per-piece pricing. Volume discounts are common for large lots. The cost almost always pays for itself — accurate grading helps sellers identify and market their highest-value logs separately rather than selling everything at an average price.
Can I grade my own logs?
You can learn the basics of log grading, but professional grading carries more weight with buyers. Certified graders have training and experience that ensures consistent, credible assessments. If you’re selling a small number of logs, self-grading with a reference guide may be sufficient. For larger sales or high-value species like walnut and white oak, hiring a professional grader is strongly recommended — the improved pricing typically exceeds the grading cost several times over.
