A Grade:

• Minimal gum or interior defect.
• Light color. Note: color is evaluated in this grade but is not as critical as in AA grade
• Even, concentric texture (growth rings)
• No excessive sap wood
• Minimum diameter of 13" at small end of log
• 4-side clean exterior with minimal amount of defect (pins or in-grown bark)
• Straight with centered hearts and good form
  Note: The wood quality is comparable to the AA grade but in a smaller diameter. The largest percentage of logs in this grade will be less than 17 inches diameter at the small-end.

B Grade:

• Acceptable proportions of scattered gum or other interior defects (bird peck, in-grown bark)
• Wood color and texture are not taken into account for this grade
• No ring gum.
• Minimum diameter of 13" at small end of log
• Straight with centered hearts
• 4-sides clear with minimal exterior defects (limited in-grown bark, light pin-knots or figure are acceptable for this grade)
  Note: the largest percentage of logs will be in 9 and 10 feet lengths or multiples of.

C Grade:

• No interior wood defects that can lower the logs yield. (heavy ring gum or bird=peck that could cause ring shake.)
• No excessive in-grown bark or large gum pockets
• No large pin-knot clusters
• Minimum diameter of 12" on the logs small-end
• Minimum of 3 clear sides (no cut-off limbs allowed)
• 4 side clear logs with interior wood defects not acceptable in B grade logs
• Straight with good form
• Butt logs or very clean second cut logs with good dimension
  Note: No more than 20% second cut logs in any #3 grade parcel
  No more than 20% of 12" and 13" diameter logs in any #3 grade parcel
• Knots must be contained in one of the log's 4 faces. Knot size can not be larger than 25% of the log's diameter on the small end.
