UNSPSC 73100000: Plastic and chemical industries

UNSPSC 73100000 Plastic and chemical industries is a Family code covering the procurement of chemical products, materials, and related supplies by state and local governments. Recent state and local solicitations under this code show purchasing focused on specialized chemicals and chemical-resistant components for water treatment infrastructure, environmental compliance, and municipal operations—including sodium bisulfite for water pollution control facilities, sodium hypochlorite injection system parts (PVC, CPVC, polypropylene tubing and fittings), liquid polymer for wastewater treatment, and general chemical supply contracts. The scope diverges significantly from abstract commodity classification; actual procurement activity centers on consumable chemicals and durable chemical-resistant components that support critical public infrastructure rather than bulk plastic or broad-category chemical industries goods.

Issuing bodies soliciting under this code include municipal utilities (water pollution control authorities, water departments), county environmental departments, and city public works agencies across multiple states. Repeat buyers include the City of Meriden, Connecticut (multiple chemical and treatment-supply bids), Tucson Water in Arizona (chemical-resistant parts and water disinfection equipment), and Stamford Water Pollution Control Authority in Connecticut (polymer supply). Geographic spread includes Arizona (Tucson Water procurement), Connecticut (Meriden and Stamford municipal utilities), Colorado (wastewater and watershed-related environmental procurement), and Florida (county waste and recycling services). Representative recent opportunities include Meriden's solicitation B027-15 for sodium bisulfite supply (ITB, July 29, 2026 deadline), Stamford WPCA's bid for liquid polymer material supply (IFB, September 24, 2026 deadline), and Tucson Water's IFB 240040 for chemical-resistant parts including PVC and polypropylene tubing for sodium hypochlorite injection systems (published August 18, 2023). Most recent pricing structures reflect unit-cost or per-ton evaluation on a competitive sealed-bid basis, with emphasis on product quality, chemical compatibility, and compliance with water treatment standards. Prevailing wage and Davis-Bacon requirements apply to some water infrastructure projects funded through EPA grants or federal appropriations.
