Paint & Coatings Freight Class Calculator

Paint and coatings represent a large and consistent freight category driven by construction activity, maintenance cycles, and consumer DIY spending. Sherwin-Williams, PPG, Benjamin Moore, and Rust-Oleum supply independent paint dealers, home improvement retailers, and contractor direct accounts. Paint manufacturers often run their own regional delivery fleets for local markets, but longer-haul distribution to regional warehouse accounts and independent dealers creates regular carrier opportunities.

Freight class for paint is Class 65–70. Liquid paint is moderately dense — a gallon of latex paint weighs approximately 10–12 lbs, and a case of four gallons weighs 45–50 lbs in roughly 0.5 cubic feet — that is 90+ lbs/cuft, which technically is Class 50 territory. But NMFC paint classifications account for the liquid nature, packaging, and hazmat considerations and place most paint at Class 65–70. Five-gallon buckets are similarly dense.

The regulatory dimension depends on the specific product. Water-based latex and acrylic paints are generally not regulated as hazardous materials when properly packaged. Oil-based paints, varnishes, lacquers, and wood stains contain flammable solvents and are classified as Class 3 Flammable Liquids under DOT regulations, requiring hazmat endorsement, proper labels and placards, and shipping papers. Spray paint aerosols are Class 2.1 Flammable Gas. Carriers must check each product carefully.

Leak prevention is the primary operational concern. Paint containers — cans, buckets, and pails — have friction-fit or threaded lids that may not be fully sealed from the manufacturer. Any opening in a lid allows paint to leak during transit if the container tips or is subject to pressure change. Paint leaking from one can can contaminate an entire pallet and create massive cleanup costs. At pickup, verify that all lids are fully seated and add a layer of pallet wrap over the top of paint loads. Rate context: paint freight pays well when hazmat premiums apply. Volume paint distribution accounts are desirable for carriers with appropriate compliance.
