UNSPSC 10171803: Limestone fertilizer

Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate. Additional chemicals vary depending on the mineral source and may include calcium oxide. Unlike the types of lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide), powdered limestone does not require lime burning in a lime kiln; it only requires milling.

UNSPSC 10171803 Limestone fertilizer (Commodity) shows no recent state and local government procurement activity directly aligned with the code's stated scope. The source contains 40 recent state and local opportunities posted between April and July 2026, spanning construction, landscaping, utilities, transit, and fleet services across jurisdictions including Collier County (Florida), Orange County (Florida), the City of Orlando, the City of Palo Alto, Sacramento County, and others. Notably, the single opportunity nominally tagged to this code—Collier County Board of County Commissioners' ITB 25-8571 for transit shelters and amenities, posted July 16, 2026, with bids due August 17, 2026—describes procurement of bus shelter structures, waste containers, benches, bike racks, and solar lighting components with no limestone fertilizer content. The mismatch between the code assignment and actual deliverables indicates this code does not currently drive active purchasing in state and local government, or the code was applied in error to that single opportunity.

The absence of limestone fertilizer solicitations across the recent opportunities block suggests limited or dormant activity under this Commodity code at the state and local level during this period. Firms considering pursuit under UNSPSC 10171803 would benefit from monitoring the code for any future activity, as the recent posting volume in adjacent agricultural and maintenance supplies categories (such as the maintenance MRO solicitations and erosion control services shown for other codes) indicates state and local bodies do procure commodity goods but not limestone fertilizer within the sample period captured here.
