(1) Before marketing or processing, all varieties of hops produced in the state of Washington must be inspected and certified by the Federal/State Hop Inspection Service for quality and condition of seed, leaf and stem according to the standards established by the Federal Grain Inspection Service of the United States Department of Agriculture. Hops that are sold in fresh green (undried) form are exempted from this requirement. Experimental hop selections that are harvested and dried for testing and evaluation, but are not sold, are exempted from this requirement.

(2) Any hops that are baled on a producer's farm must be officially sampled by a Washington state department of agriculture inspector. If a lot of hops totals less than one thousand two hundred pounds, the grower may utilize a submitted sample in lieu of official sampling for determination of seed, leaf, and stem. Submitted samples must be collected in a random fashion and provide a minimum of 0.5 kg for evaluation.
