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 that shows no recent state and local procurement activity aligned with its nominal scope. The three most recent opportunities tagged to this code—janitorial and operational supplies for Hillsborough County Fire Rescue (ITB, due Jul 24, 2026), instructional resources for Klein Independent School District in Texas (RFP, due Jun 5, 2026), and emergency refrigerator truck rental for the City of Tucson Police Department (RFQ, due Jun 20, 2025)—bear no substantive connection to copper sulfate solution or specific gravity determinations. The mismatch suggests either systematic miscoding in state and local procurement systems or that the code is rarely if ever used for its intended commodity in the jurisdictions currently posting opportunities.

Without recent solicitations actually requesting copper sulfate solution or related laboratory chemical supplies, no reliable characterization of issuing-body mix, geographic concentration, or representative work is possible. Firms targeting this code should verify independently whether state and local buyers use UNSPSC 41131615 for chemical procurement, or whether related chemistry supply needs are tagged to alternative codes. Until concrete opportunities align with the code's scope, pursuit carries high overhead and low probability of yield.
