UNSPSC 51202003: Polystyrene sulfonate

This classification denotes an electrolyte replacement agent with the molecular formula C2H6(C8H9O3S)N.(C8H8(C2H3)XL)N, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 70KO0R01RY. SMILES: C=CC1=CC=CC=C1S(=O)(=O)[O-].[CA+2].

UNSPSC 51202003 Polystyrene sulfonate is a Commodity code that state and local health departments use to procure specialized pharmaceutical products. The recent activity under this code shows minimal alignment with the code's nominal scope — the single recent opportunity posted by the Mississippi State Department of Health (Jul 13, 2026) is a sole source notice for Yellow Fever Vaccine from Sanofi Pasteur, Inc., which falls outside the polystyrene sulfonate category and suggests either a data-tagging mismatch in the procurement system or a very narrow therapeutic-use classification that does not reflect typical purchasing patterns under this code. State and local health authorities are the primary issuing bodies under this code when activity does appear, purchasing vaccines and related pharmaceutical supplies for public health programs and disease prevention initiatives.

The source contains only one recent opportunity, limiting visibility into geographic spread or a pattern of competitive activity. The Mississippi State Department of Health's sole source notice (objection deadline Aug 3, 2026 at 10:00 a.m. CST) is procedural rather than a standard RFP, RFQ, IFB, or ITB, and does not disclose quantity, contract term, or estimated value. The code shows little relevant recent activity, and the single posted opportunity suggests that typical procurement under UNSPSC 51202003 may occur outside standard competitive channels or that state and local agencies tag health-supply purchases inconsistently across the taxonomy.
