Gases, such as natural gas, nitrogen, carbon dioxide, helium, oxygen, propane, acetylene and nitrous oxide, are tangible personal property. Therefore receipts from selling gases to a 501(c)(3) organization may be deducted from gross receipts under Section 7 9 60 NMSA 1978 if the organization delivers a properly executed non-taxable transaction certificate or alternative evidence to the seller.
