Success in buying and selling forest products depends on one’s knowledge of product measurement and ability to predict the current market value. When trees are harvested, they can be sold as whole trees, factory class sawlogs, construction class sawlogs, veneer logs, pulpwood and/or chipwood. Lumber is sold by its grade, which is determined by the size and location of defects. Each product from the forest has a particular method by which it is measured and its market value estimated. This publication explains common forest products measures used in Tennessee and how to estimate the current market value.
