UNSPSC 51201808 Levamisole or tetramisole is a Commodity code covering antiparasitic pharmaceuticals used in veterinary medicine, though state and local procurement activity under this code shows little direct alignment with the nominal product. Recent solicitations tagged to this code actually reflect broader animal-shelter and veterinary-services procurement spanning pharmaceutical supplies, clinical materials, and comprehensive veterinary-service contracts. State and local governments buying under this taxonomy are primarily county animal-services divisions and municipal animal-shelter operations, with Collier County (Florida) appearing as a repeat buyer across multiple complementary solicitations for veterinary services, trap-neuter-vaccinate-release (TNVR) programming, and pharmaceutical supply contracts.

Recent activity concentrates in Texas and Florida. Representative recent opportunities include Williamson County Regional Animal Shelter's IFB for pharmaceuticals and clinic supplies (26IFB24, due April 23, 2026) requesting oral medications, electronic ordering capability, and two-week delivery to support ongoing shelter operations; the City of Dallas's informal solicitation for veterinary pharmaceuticals (IFSDASB1700022, due February 12, 2026) through its Dallas Animal Services facility; and Collier County's comprehensive veterinary-services ITN (ITN 25-8347, due February 4, 2025) spanning full medical management for dogs, cats, small mammals, and reptiles with three-year contract term and local-vendor preference weighting. Harris County Public Health Services Office in Texas posted an ITB for pet clinic supplies and related items (260161, due July 27, 2026). The code shows no standout repeat vendors or significant geographic concentration beyond the Texas and Florida municipalities named in recent postings.
