UNSPSC 51441612 Ibritumomab tiuxetan 90y is a Commodity code nominally describing a radioimmunotherapy pharmaceutical product, yet recent state and local procurement activity under this code shows no alignment with that scope. The two most recent opportunities tagged to this code involve X-ray inspection system maintenance services (Broward County Aviation Department) and copper sulfate supply (Pasco County, Florida) — neither pharmaceutical in nature nor related to radiotherapy agents. The mislabeling suggests either data-entry error in the opportunities or misclassification of the code itself within the source systems. State and local procurement activity under this code does not reflect genuine demand for the pharmaceutical product the code nominally describes.

Geographic activity is limited to Florida, with the only recent solicitations originating from Broward County and Pasco County. Broward County Aviation Department posted an RFI (due July 28, 2026) to determine whether maintenance and repair services for proprietary Rapiscan X-ray inspection systems are available from sources other than the manufacturer, while Pasco County issued an RFQ (due June 26, 2026) for as-needed supply of large copper sulfate crystals and liquid copper sulfate. Neither opportunity aligns with pharmaceutical procurement patterns or radiotherapy support services. No additional state, county, or municipal activity under this code appears in the recent-opportunity record.
