Question-  Why can’t some CerMark/TherMark products be shipped via air freight without additional charges?

Answer-  Aerosol cans (LMM14 , LMM6000 and New Ultra ) and alcohol-based chemicals (LMM6000, LMM6038, LMM6046 ) are considered a safety risk on airplanes due to being pressurized and flammable. CerMark employees are trained and certified to ship dangerous goods via air both domestically (under DOT 49 CFR) and internationally (under IATA). While CerMark does not charge extra for this service, freight companies impose additional charges due to the added regulatory complications of these products, and we are forced to pass these along to the customer.
