Question
What would an NHLA grader charge per thousand board feet to grade hardwood, if he were to come to a mill?

From Professor Gene Wengert, forum technical advisor:
You probably do not need an NHLA grader, but rather a person that is familiar with the rules and is a practicing hardwood grader. The graders for hardwood lumber are not certified. Some mills are certified. Usually, when there is a dispute between buyer and seller, then the NHLA will send one of their graders to settle the dispute. Such grading services by the national inspectors are expensive indeed. The amount you pay a grader is negotiated and varies all over the map.
