Interagency seed certification standards—Seed produced out-of-state.
(1) Certified seed produced out-of-state and shipped into Washington state for processing is eligible for Washington interagency tags only after obtaining approval from the certifying agency of the originating state. The seed must then comply with Washington certification standards.
(2) Certified seed produced out-of-state that is officially tagged and sealed must be handled under the interagency program if seals are to be broken for reinoculation or other processing. The applicant for interagency seed certification must obtain approval from the department prior to breaking the official seals and all operations must be under the supervision of the certifying agency.
