Contractual scaling agreements regarding gross scale determination may not establish any scaling requirement that differs from those stated in the "Idaho Log Scaling Manual" or the "Idaho Cubic Log Scaling Manual" except for a minimum top diameter that may be smaller than five and fifty-one hundredths inches (5.51") actual measure. Licensed scalers will be provided with written scaling specifications that denote any minimum top diameter that is smaller than five and fifty-one hundredths inches (5.51") actual measure.
