UNSPSC 31231400: Shim stock

UNSPSC 31231400 Shim stock, a Class code, covers precision metal and composite shims—thin spacer materials used to adjust alignment, fill gaps, and maintain tolerances in machinery, equipment assemblies, and structural applications across state and local procurement. State and local governments procure shim stock primarily through maintenance and repair operations for fleet vehicles, heavy equipment, HVAC systems, and facility infrastructure; the material appears in both standalone RFQs for replacement parts and as line items within larger equipment-service and capital-maintenance contracts. Issuing bodies include state departments of transportation, public works divisions, county maintenance facilities, municipal equipment shops, and school district facilities departments. The code serves as a consumable material category rather than a specialized commodity, meaning opportunities tend to be routine and recurring rather than one-time acquisitions.

The <most-recent-state-local-contract-opportunities> block provided no records, indicating minimal or no recent solicitation activity under this specific code across the state and local market. This absence of posted opportunities suggests either that shim stock is routinely procured through standing supply contracts, cooperative purchasing agreements, or vendor-managed inventory arrangements rather than through competitive RFQ or IFB notice cycles, or that issuing bodies tag such purchases under broader fastener, hardware, or equipment-parts codes. Firms targeting this code should monitor cooperative purchasing vehicles and blanket-order frameworks used by state departments of transportation and county equipment maintenance divisions, where shim stock demand is steady but procurement visibility remains low.
