UNSPSC 31161810: Shim washers

UNSPSC 31161810 Shim washers is a Commodity code that in practice covers fasteners and hardware components procured by state and local transit authorities, utilities, and municipal infrastructure departments. The recent opportunities tagged to this code show a disconnect: the Dallas Area Rapid Transit Authority (DART) posted an IFB for bolts (1/2"-13 X 2-3/4") with a response date of September 11, 2026, while the City of Lavonia, Georgia, solicited sealed competitive bids for water treatment plant improvements encompassing construction services, site work, and system upgrades. The bolt solicitation aligns directly with the code's fastener scope; the water treatment construction project does not, suggesting a tagging misalignment in the source data for the second opportunity. Transit authorities and municipal utilities appear to be the primary issuing bodies under this code, though the recent data set is too sparse to characterize concentration or repeat-buyer patterns.

Activity under the code is limited in the recent records. DART's fastener procurement and the water treatment project together span Georgia and Texas, but only the DART bolt purchase represents genuine Commodity-level activity under 31161810. The bolt solicitation required FOB Destination shipping, Net 30 payment terms, and BONFIRE registration for bid access—standard municipal procurement mechanics. No additional recent shim washer or related fastener solicitations appear in the source data. State and local procurement professionals should verify whether the water treatment opportunity is correctly coded or represents a categorization error before allocating resources to this Commodity.
