Nitrous Oxide

Pursuant to N.J.S.A. 24:6G, applicants who wish to buy, sell, purchase, or distribute nitrous oxide must complete a permit application and provide photo ID (I.e., Driver’s license, passport, birth certificate).

All individuals selling nitrous oxide for food preparation purposes are required to verify that the purchaser provides proof that they are at least 19 years of age before the sale is made. Sellers must also keep a record of all sales in accordance with N.J.S.A. 24:6G-3. Records should include the name and address of the buyer, permit number, date of sale, and amount of nitrous oxide purchased.

Please make sure that the place where you purchase nitrous oxide is properly registered with the Public Health and Food Protection Program under the NJ Department of Health. Every permit issued by the NJ Department of Health for the use or sale of nitrous oxide is valid only for the location listed in that permit and is not transferable.

To ensure permits remain active, applicants must maintain the license by reapplying every two years. For current permit holders, renewal postcards will be sent out the month prior expiration.

Renewal reminder postcards are mailed to each registrant at least one month before expiration.
It is the registrant's responsibility to download the renewal application form online.

Renewal forms are no longer mailed.
