This classification denotes an anti-ulcer agent with the molecular formula CO3.2Bi.2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier M41L2IN55T, chemically known as carbonic acid, bismuth salt but generally known as bismuth carbonate, which bears US NIH Compound Identifier 161253. European Medicines Agency schedules Bismuth carbonate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13088MIG. As of Q4 2014, BISMUTH SUBCARBONATE remains the US FDA Preferred Term for this commodity.

UNSPSC 51171713 Bismuth subcarbonate is a Commodity code that shows no recent state and local procurement activity aligned with its nominal scope. The single opportunity in the recent record — Collin County Community Supervision and Corrections Department RFP 2026-327 for offender specimen collection and drug testing services — does not involve bismuth subcarbonate procurement and appears to be a miscoded tag applied to a forensic laboratory and field testing services contract. The mismatch suggests either a data-entry error in the county's procurement system or an incorrect association between the opportunity and the chemical commodity code.

Without genuine bismuth subcarbonate opportunities in the recent state and local record, no reliable characterization of issuing-body patterns, geographic concentration, or representative work under this code can be drawn from the source. Businesses evaluating this Commodity code should verify whether state and local procurement systems are using it correctly and monitor whether activity emerges in coming quarters.
