Idaho Code § 22-3106: Markings required.

In addition to any other brands, labels, stencils, or other marks approved by the commission to be placed upon hops, all hops shall be branded, labeled, stenciled or marked with one (1) identifying distinctive mark defined or designated by the commission which shall identify the hops as having been grown in Idaho. This identifying distinctive mark shall be affixed in such position and manner as the commission may by rule or regulation prescribe to each container of hops or bale at the time such hops are first handled in the primary channels of trade by the person who first handled such hops in the primary channels of trade. No person shall brand, label, stencil or mark any hops, except hops as defined in this act, with such identifying distinctive mark defined or designated by the commission as herein provided.
