UNSPSC 24111819 Hydropneumatic tank is a Commodity code that in recent state and local procurement covers CO2 tank rental, refill, and delivery services to support public facility operations, as well as underground storage tank removal and decontamination. Collier County, Florida has posted two separate Quick Quote solicitations (QQ2026144 and QQ2026136) for monthly rental of nine 750-cubic-foot CO2 tanks and five 125-cubic-foot portable tanks, plus refill and delivery services to six aquatic facilities across the county parks system through September 30, 2027. The City of Meriden, Connecticut issued an Invitation to Bid (ITB B027-12) for removal, decontamination, and disposal of a 4,000-gallon double-wall underground storage tank at a fire station, requiring Connecticut state certification and a minimum of two years of tank removal experience. The issuing bodies include county parks and operations departments and municipal fire and public works departments, with single-source procurement occurring via informal Quick Quote and traditional competitive IFB processes. Vendors typically must provide proof of business registration, current licenses, E-Verify enrollment, and insurance covering Workers' Compensation, General Liability, Employer's Liability, and Automobile Liability; tank removal contractors face additional state certification and experience requirements.

Recent activity is concentrated in Florida and Connecticut. Collier County's two CO2 rental solicitations represent repeat procurement under this code, with contract terms running through September 30, 2027 and pricing locked at firm rates. The City of Meriden's tank removal bid (ITB B027-12) closed September 9, 2026, with site visits required and Connecticut prevailing wage applying; a local-vendor preference applies to city-based businesses, and Connecticut state certification is a central eligibility filter.
