UNSPSC 51101607: Calcium oxide

This classification denotes a dental material with the molecular formula Ca.O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier C7X2M0VVNH, chemically known as lime, burned but generally known as calcium oxide, which bears US NIH Compound Identifier 14778. European Medicines Agency schedules Calcium oxide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13189MIG. Most nations schedule calcium oxide under HS 28259000 and SITC 52269. SMILES: O=[CA].

UNSPSC 51101607 Calcium oxide is a Commodity code that shows little relevant recent activity in state and local procurement. The two most recent opportunities tagged to this code—a pharmaceutical warehouse contract for antibiotics through the Illinois Department of Public Health and a naloxone and drug deactivation systems procurement by Seminole County, Florida—bear no relationship to calcium oxide as a chemical product. The mismatch suggests either classification error in the source data or that state and local buyers are not actively soliciting calcium oxide under this code at present.

No open solicitations for calcium oxide products appear in recent state and local contract postings. Without active opportunities or a pattern of issuing bodies, geographic regions, or representative work scopes tied to the code's actual commodity definition, there is no basis to characterize market activity or procurement intent under this UNSPSC category.
