UNSPSC 41131615: Copper sulfate solution for specific gravity determinations

In this classification, a copper sulfate solution for specific gravity determinations is a device used to determine whether the hemoglobin content of a potential donor's blood meets the required level (12.5 grams per 100 milliliters of blood for women and 13.5 grams per 100 milliliters of blood for men). US FDA regulates Copper sulfate solution for specific gravity determinations under 21 CFR 864.9320 and under FDA product code KSL.

UNSPSC 41131615 Copper sulfate solution for specific gravity determinations is a Commodity code with little recent activity closely aligned to its nominal scope. State and local procurement records show sparse use of this code, and the two most recent opportunities tagged to it diverge sharply from its chemical-compound focus: one covers blood transfusion equipment (the State of California Emergency Medical Services Board), and the other covers janitorial and operational supplies (Hillsborough County Fire Rescue). Neither solicitation involves copper sulfate solutions or specific gravity testing. The mismatch suggests the code is either misapplied in state and local taxonomy systems or that procurement offices rarely tag chemical-testing reagents to commodity-level UNSPSC codes. Absent concrete evidence of active demand under this code's intended scope, the category presents limited pursuit opportunity for vendors in chemical reagents or laboratory consumables.

No representative recent opportunities in copper sulfate solution procurement are present in the available records. Buyers of testing chemicals and laboratory materials at the state and local level may classify such purchases under broader chemical or laboratory-supplies families rather than this specific commodity code, or may source reagents through cooperative purchasing vehicles or pre-qualified scientific-supply vendors outside the formal solicitation channel. Tracking this code's activity would require monitoring whether future RFPs or IFBs from state health departments, environmental agencies, or educational institutions resurface it with demand for actual chemical products.
