UNSPSC 51191556 Lemidosul is a Commodity code for a specialized pharmaceutical or chemical product with limited recent state and local procurement activity. The two identifiable recent opportunities under this code reveal a significant mismatch: one solicitation (City of Meriden, Connecticut) concerns sodium bisulfite for water treatment—a chemical commodity unrelated to the code's nominal scope—while the other (Minnesota Multistate Cooperative Purchasing Alliance) addresses generic pharmaceuticals and over-the-counter products supplied through authorized wholesalers. The sodium bisulfite bid is a straightforward municipal chemical supply contract with unit-cost pricing and standard bonding requirements; the pharmaceutical RFP is a multi-state cooperative vehicle serving state and local health and human services facilities across multiple states including Oregon. Neither opportunity directly aligns with Lemidosul as a discrete product line, suggesting the code may be misapplied in practice or the product sees minimal state and local procurement volume relative to the breadth of the taxonomy.

Geographic activity is confined to the Northeast (Connecticut) and Upper Midwest (Minnesota and Oregon via MMCAP). The City of Meriden IFB for sodium bisulfite closed July 29, 2026; the Minnesota Department of Administration's RFP for generic pharmaceuticals and OTC products through MMCAP closed March 26, 2026, with a two-year contract term effective July 1, 2026, and optional extensions through June 30, 2028. Issuing bodies are mixed between a single municipality (Meriden) and a multi-state cooperative administered at the state procurement office level. The mismatch between the code name and actual solicitation content suggests that pursuing opportunities under UNSPSC 51191556 may require direct confirmation that the work aligns with your firm's capabilities, as the code does not appear to concentrate volume in a single product or service line.
