Minn. Stat. § 297A.73: IMPROPER USE OF ITEM OBTAINED WITH EXEMPTION CERTIFICATE.

If a purchaser who gives an exemption certificate makes any use of the item that is not for a purpose exempted under this chapter, that use is considered a retail sale by the purchaser and the sales price to the purchaser is considered the gross receipts. If the sole use is rental while holding for sale, the purchaser shall include in the purchaser's gross receipts the amount of the rental charged. Upon subsequent sale of the item, the seller shall include the entire amount of gross receipts received from the sale without deduction of amounts previously received as rentals.
