UNSPSC 51182401 Calcium chloride is a Commodity code covering chemical supply for water treatment and pollution control operations at municipal facilities. State and local governments procure under this code primarily for water quality management — specifically treatment chemicals used in wastewater and water pollution control systems. Recent activity shows municipalities issuing IFB notices to source individual chemical commodities, with pricing evaluated on a unit-cost basis for estimated quantities and contract terms ranging from single-year to multi-year periods. Issuers soliciting under this code are primarily municipal water and wastewater authorities, though the recent opportunities block shows limited volume — only one solicitation directly aligned with chemical supply for water treatment operations.

The City of Meriden, Connecticut posted IFB B027-15 on July 8, 2026, seeking sodium bisulfite for its Water Pollution Control Facility with bids due July 29, 2026. This represents the most directly relevant recent activity under the code. The Meriden solicitation requires performance and payment bonds, standard commercial general liability coverage of $1,000,000 to $2,000,000 with the municipality named as Additional Insured, and firm pricing for the stated contract period. Geographic concentration appears limited; Connecticut shows recent activity, but the source provides insufficient data to characterize broader regional or multi-state purchasing patterns under this Commodity code. The broader municipal water treatment chemical procurement market may be fragmented across individual jurisdictions issuing small-volume, item-specific bids rather than centralized or cooperative purchasing arrangements.
