Wis. Stat. § 407.201: Person that may issue a warehouse receipt; storage under bond.

(1) A warehouse receipt may be issued by any warehouse.

(2) If goods, including distilled spirits and agricultural commodities, are stored under a statute requiring a bond against withdrawal or a license for the issuance of receipts in the nature of warehouse receipts, a receipt issued for the goods is deemed to be a warehouse receipt even if issued by a person that is the owner of the goods and is not a warehouse.
