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, but the recent state and local opportunities tagged under it show no purchases of calcium oxide itself. Instead, the tagged solicitations document procurement of naloxone and drug deactivation systems, prescription pharmaceuticals, medical and first aid supplies for fire rescue operations, and generic multi-source pharmaceuticals and OTC products distributed through authorized wholesalers. The mismatch between the code's nominal scope and the actual solicitations indicates that this code shows little relevant recent activity aligned with its commodity definition. State and local purchasing offices appear to be using this code as a catchall or have miscoded these health-care and pharmaceutical acquisitions, which belong in different taxonomic families. The issuing bodies posting under this code include county health departments (Seminole County, Florida), state health agencies (Texas HHS Commission), municipal fire departments (City of Tampa), and cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance serving multiple jurisdictions including Oregon).

Recent opportunities span Florida, Texas, Minnesota, and Oregon, with geographic concentration in the Southeast and Upper Midwest. Representative solicitations include Seminole County's IFB for naloxone and safe drug deactivation systems (posted June 30, 2026; due July 26, 2023), the City of Tampa's IFB for medical and first aid supplies for the Fire Department Rescue Division with an estimated contract value of $700,000 and SLBE set-aside with a 5 percent bid discount (posted March 25, 2026; due March 13, 2026), and the Minnesota Multistate Cooperative Purchasing Alliance's RFP for generic multi-source pharmaceuticals and OTC products through authorized wholesalers (posted January 20, 2026; due March 26, 2026). The code's tagging under pharmaceutical and medical-supply procurements rather than calcium oxide suggests that business development professionals should verify actual commodity alignment before investing pursuit effort, as the code label does not reflect the work state and local governments are actually buying.
