RCW 22.09.060

Except as provided in RCW 22.09.405(2), no warehouse or grain dealer license may be issued to an applicant before a bond, certificate of deposit, or other security is given to the department as provided in RCW 22.09.090, or in RCW 22.09.095. No warehouse license may be issued to an applicant before a certificate of insurance as provided in RCW 22.09.110 has been filed with the department. Grain dealers may be exempted by rule from the bonding requirement if the grain dealer does not do more than one hundred thousand dollars in business annually and makes payments solely in coin or currency of the United States at the time of obtaining possession or control of grain. However, a cashier's check, certified check, or bankdraft may be considered as cash for purposes of this section.
