NIGP 40557: Oil, Lubricating: Differential and Gear Lubricant

NIGP 40557 Oil, Lubricating: Differential And Gear Lubricant, Item tier, encompasses differential oils, gear lubricants, and related specialized lubricating products that state and local governments procure for fleet maintenance, school bus operations, facilities equipment, and specialized industrial machinery. Recent solicitations show state and local buyers treating this code as part of a broader petroleum lubricants and fluids procurement family—differential and gear oils appear alongside motor oils, transmission fluids, grease, hydraulic oils, antifreeze, and diesel exhaust fluid in multi-category RFBs and ITBs. The issuing-body mix spans school districts (Parkway School District, Rockwood School District, Pinellas County School District, Cobb County School District, Harlingen Consolidated ISD, and Hillsborough County Public Schools), state procurement offices (South Dakota Office of Procurement Management, Washington State Department of Enterprise Services), counties (Collier County, Palm Beach County's Solid Waste Authority), and municipalities (City of Tampa, City of Port Orange). School districts and state transportation or fleet-management departments dominate recent activity, typically bundling differential and gear oils into broader fleet-maintenance contracts supporting school buses, grounds equipment, and vehicle fleets.

Recent opportunities concentrate in Florida and the Upper Midwest, with standout volume in Florida school districts and the State of South Dakota. Representative recent solicitations include the Washington State Department of Enterprise Services ITB 09225-02 (issued July 10, 2026, bids due July 30, 2026) for statewide bulk lubricants across four categories with approximately $5.1 million in estimated annual sales and forty-eight-month contract terms; Pinellas County School District ITB 26-AM-018 (bids due August 26, 2026) for petroleum lubricants and antifreeze valued at approximately $135,000 annually across four bus and maintenance facilities; Rockwood School District RFB 2026-27 Shop Fluids (bids due September 24, 2026) for school bus and grounds equipment maintenance fluids running October 1, 2026 through June 30, 2027; the State of South Dakota Office of Procurement Management IFB 26IFB19994 (bids due November 4, 2026) for statewide lubricants and maintenance fluids; and Parkway School District Solicitation 2751 (bids due October 27, 2026) for blanket-purchase lubricants on an as-needed basis. Cooperative purchasing with state contracts occurs—Pinellas County School District considers pricing from Florida Department of Management Services contracts as part of evaluation. Single-source and intent-to-single-source notices also appear (Collier County's proposed five-year contract with Schaeffer Manufacturing Company effective October 1, 2026, and City of Port Orange's notice for NOV Chemineer Moyno pump products with Carl Eric Johnson, Inc., estimated at $500,000 annually), indicating some jurisdictions have established preferred suppliers for specialized lubricant products.
