MoDOT Statewide Herbicide

The Missouri Department of Transportation (MoDOT) is issuing an Invitation for Bid (IFB) for the procurement of herbicides to support statewide highway maintenance operations covering approximately 90,000 acres annually. The contract period runs from February 1, 2026 through January 31, 2028, with three additional one-year renewal option periods available at MoDOT's discretion. All herbicides must be registered in Missouri, manufactured in the United States, and labeled for use on highway right-of-way. Qualified suppliers must deliver herbicides within 10 working days of order placement and provide Manufacturer's Labels and Safety Data Sheets with each delivery. Pricing must be submitted on a completed herbicide pricing spreadsheet using a standardized formula evaluating cost per 100 gallons for additives, with award made to the lowest responsive bidder meeting all mandatory specifications and requirements. Prospective bidders must submit bids electronically through MissouriBUYS or by hard copy delivery by December 23, 2025 at 2:00 PM Central Time, and those submitting hard copies must contact buyer Nanci Grannemann at Nanci.Grannemann@modot.mo.gov at least five business days prior to the bid closing date. No pre-bid conference or facility tour is scheduled for this procurement.

The Domestic Products Procurement Act applies to this commodity purchase, offering a 10 percent preference to bidders providing American-made products. All contractors must be registered in MissouriBUYS to be considered for award and must submit completed exhibits including the Anti-Discrimination Against Israel Act Certification and Domestic Products Procurement Act Preference documentation. Contractors are required to maintain adequate liability insurance with MoDOT named as an additional insured, and the contract includes liquidated damages of $100 per day per item for late deliveries. No price increases are permitted during the first six months of the original contract period or any renewal period. The solicitation does not identify a specific budget range or award value; however, given the scale of treating 90,000 acres annually statewide, this represents a significant procurement opportunity for qualified herbicide suppliers.
