Hi Stewart. I'm not certain on the exact legislation myself, but there is regulation on solvents by volume. We ship with UPS and so UPS charges us a Hazmat fee, but for other solvents like our Iso-alcohol we ship out "one gallon" as four quart sized bottles (packaged individually) with no hazmat fee. It's just how the laws are and what UPS charges us to ship; if the volume were larger on Amazon, they would likely also charge a hazmat fee.
