(1) Acceptance of commodities for storage by a warehouse operator shall constitute a bailment and not a sale. Stored commodities shall not be liable to seizure upon process of a court in an action against the bailee, except upon action by owners of the stored commodities or the commissioner to enforce the terms thereof; but, in the event of the failure or insolvency of a bailee, commodities shall be first applied exclusively to the settlement on an equal basis of all outstanding negotiable warehouse receipts and other open storage obligations for commodities so stored with the bailee.
(2) Forwarded commodities shall be used only to meet the storage obligation to the forwarding warehouse operator.
(3) The purchase of a commodity does not constitute a bailment.
