(1)(a) If a statement is filed pursuant to RCW 60.13.040 within twenty days of the date upon which payment from the processor, conditioner, or preparer to the producer or commercial fisher is due and remains unpaid, the processor or preparer lien evidenced by the statement continues its priority over all other liens or security interests upon agricultural products or fish, inventory, and accounts receivable, except as provided in (b) of this subsection. Such priority is without regard to whether the other liens or security interests attached before or after the date on which the processor or preparer lien attached.
(b) The processor or preparer lien shall be subordinate to liens for taxes or labor perfected before filing of the processor or preparer lien.
(2) If the statement provided for in RCW 60.13.040 is not filed within twenty days of the date payment is due and remains unpaid, the processor or preparer lien shall thereupon become subordinate to:
(a) A lien that has attached to the agricultural product or fish, inventory, or accounts receivable before the date on which the processor or preparer lien attaches; and
(b) A perfected security interest in the agricultural product or fish, inventory, or accounts receivable.
