About NIGP 05521
NIGP 05521 Couplings And Hitches, an Item code, encompasses mechanical connection components and trailer hitches that state and local governments procure for fleet maintenance, public works equipment, and facility operations. The recent solicitations under this code reflect demand for specialty trailer equipment and automotive coupling systems rather than standalone hitches alone—the Orange County Air-tow Utility Trailer procurement (solicitation 0802978201RN, IFB, response due January 7, 2026) specifically calls for tandem axle trailers with electric brakes and hydraulic lift mechanisms, while the Brevard County Fleet Services inventory management solicitation (B52621, IFB, response due February 25, 2026) includes automotive parts and equipment sourcing for a county fleet of 1,114 assets. School districts and counties dominate the issuing-body mix; the School Board of Sarasota County (solicitation 260124, response due February 12, 2026) established a one-year supply agreement for automotive and light truck repair parts with percentage discounts off manufacturer list prices. The Berkshire Regional Group Purchasing Program in Massachusetts (FY2704, IFB, response due April 2, 2026) bundled culvert products with twenty other highway supply and service categories in a cooperative purchasing vehicle serving 32 participating municipalities across Berkshire County.
Recent activity concentrates in California, Florida, and Massachusetts. The County of Orange in California is actively procuring specialty trailers with specific coupling and brake specifications; Brevard County and the School Board of Sarasota County in Florida are sourcing parts for fleet and vehicle maintenance operations. The Berkshire Regional Group Purchasing Program in Massachusetts manages highway materials and services cooperatively across three regional subsections. No recent standalone couplings-and-hitches solicitations appear in the available opportunities—activity instead manifests as components within broader fleet-maintenance or equipment-procurement efforts, suggesting demand is embedded in larger automotive or public-works contracts rather than solicited as discrete commodity purchases.
