UNSPSC 41131616: Stabilized enzyme solution

In this classification, a stabilized enzyme solution is a reagent intended for medical purposes that is used to enhance the reactivity of red blood cells with certain antibodies, including antibodies that are not detectable by other techniques. These enzyme solutions include papain, bromelin, ficin, and trypsin. US FDA regulates Stabilized enzyme solution under 21 CFR 864.9400 and under FDA product code KSK.

UNSPSC 41131616 Stabilized enzyme solution is a Commodity code nominally covering biochemical solutions used in industrial and institutional cleaning applications. However, the recent state and local opportunities tagged under this code show little direct procurement activity for the product itself. Instead, the opportunities reflect janitorial supply aggregation, academic instructional resources, and emergency equipment rental—none of which align with stabilized enzyme solutions as a discrete line item. The Hillsborough County Board of County Commissioners ITB for janitorial and operational supplies (posted July 7, 2026, due July 24, 2026) is the closest match, as enzyme-based cleaners may be included in a broad consumables contract; however, the solicitation does not isolate or emphasize enzyme solutions, and the county's stated scope encompasses a full range of operational supplies for 47 fire stations on an as-needed basis under a $765,679.84 one-year contract. The other two recent opportunities—Klein Independent School District's RFP for Career Technical Education instructional resources and the City of Tucson's RFQ for emergency freezer and refrigerator truck rental—are unrelated to the code's nominal scope and appear to be miscoded tags.

The code shows minimal recent activity with clear decision relevance for vendors in the enzyme solutions space. No opportunities explicitly solicit stabilized enzyme solutions as a standalone product, and only one of the three recent opportunities presents a tangible market opening, though enzyme-based cleaners would compete within a much broader janitorial supplies aggregation. Hillsborough County's annual spend of approximately $765,679.84 for all consumable janitorial and operational supplies across fire rescue operations represents the most concrete lead; however, sourcing detail and line-item breakdowns are not specified in the bid solicitation. Geographic activity is concentrated in Florida (Hillsborough County) and Texas (Klein ISD), with limited signal of active procurement momentum in this code at this time. Business development professionals pursuing this code should assess whether enzyme-solution volumes can justify participation in aggregated facilities-supply contracts or should monitor the code for category-specific solicitations that have not yet surfaced in recent months.
