UNSPSC 95121633: Culvert

A device used to channel water

UNSPSC 95121633 Culvert, a Commodity code, spans the material products that state and local governments buy for stormwater management, drainage, and water infrastructure projects—specifically the pipes themselves (corrugated metal pipe, corrugated aluminum pipe, polypropylene pipe) rather than culvert installation services. Recent state and local solicitations under this code show active procurement of both metallic and plastic culvert pipes across multiple sizes and delivery modes, typically issued as one-time purchase IFBs or blanket purchase agreements with firm fixed pricing and low-bid award criteria.

State departments of transportation drive the bulk of recent activity: the Missouri Department of Transportation Southwest District has posted at least nine separate IFBs in October 2026 alone for corrugated metal pipe (CMP) aluminized culverts and polypropylene pipes to multiple maintenance shed locations across the Southwest District's service area, with bid deadlines clustered around October 19–23, 2026. The St. Johns River Water Management District (Florida) solicited corrugated aluminum pipe (CAP) 30-foot sections in four diameters for conservation area installation with a February 5, 2027 delivery deadline and an estimated budget of $45,000. Seminole County (Florida) issued a master contract IFB for five public works contractors with drainage work prequalification in working class 7, which explicitly includes drainage pipe and culverts. Geographic activity concentrates in Missouri, Florida, Georgia, Oregon, and Texas; MoDOT's Southwest District dominates the recent opportunities block, with recurring procurement cycles for different geographic areas (North, Southwest, Central, Western, and I-44 Corridor). All MoDOT solicitations require products to be listed on the state's Approved Products list, compliance with specific section standards (typically Sections 724, 725, 1020–1022, or 1041), and certification of product specifications prior to award. Buy American (Domestic Products Procurement Act) preferences apply to bids of $25,000 or more; Anti-Discrimination Against Israel Act certifications apply to bids of $100,000 or more. Typical unit pricing is firm for 60–90 days, payment terms are Net 45, and freight is prepaid with FOB destination delivery. MBE and WBE participation is encouraged at 10 and 5 percent goals respectively but is not set-aside. Vendors must be registered in state eProcurement systems (MissouriBUYS, DemandStar, Central Bidding, BidNet) and carry liability insurance naming the agency as additional insured.
