What Grammer Logistics does

Grammer Logistics is a privately held, PE-backed bulk carrier specializing in hazardous materials transportation for the agriculture, energy, and chemical industries. Founded in 1968 in Grammer, Indiana, the company operates 19 locations across the Eastern and Gulf Coast US, including 12 strategic terminals co-located with major chemical production hubs, and runs a fleet of 550 tractors (split roughly evenly between owner-operators and company drivers) and over 900 specialty tank trailers rated for MC-331, DOT-407, and DOT-412 service. The company generates revenue primarily through asset-based transportation fees for anhydrous ammonia, natural gas liquids (propane, butane, gas mixes), and bulk liquid chemicals (acids, caustics, solvents), augmented by transload services and a non-asset 3PL/transportation management business operated through its LMR subsidiary.

The platform is structured around three service lines: bulk transportation of hazmat commodities, rail-to-truck and barge-to-truck transloading at strategic terminals, and managed transportation via LMR. Technology is operational rather than analytical, anchored on the McLeod ERP/TMS platform, Samsara GPS fleet tracking, SmartDrive and Lytx in-cab camera systems, Infinit-I learning management for driver training, and EDI-based load lifecycle integration with shipper ERP systems; a custom API platform is in development. The go-to-market is enterprise field sales led by a Chief Commercial Officer and dedicated business development executives, targeting Fortune 500 chemical and energy shippers, with quote-based multi-year contracts.

Since October 2018, the business has been owned by Stellex Capital Management and Mill Rock Capital, which has funded three acquisitions (Sterling Transport in 2019, LiMarCo Logistics in 2019, and LMR in 2022), a commercial headquarters in The Woodlands, TX, and a chemical division launched in 2020 that now exceeds 20% of revenue. The company reports $100M+ in 2022 revenue, 500+ shippers, and 50M+ cumulative miles, and is positioning itself as the largest for-hire pressurized gas hauler in North America under a new CEO appointed in September 2025.
