Federal law strictly prohibits carrying hazardous materials in your luggage aboard aircraft. Violating this law can lead to up to five years imprisonment and fines of $250,000 or more (49 U.S.C. 5124). Hazardous materials include explosives, compressed gases, flammable liquids and solids, oxidizers, poisons, corrosive substances, and radioactive materials.
Examples include paints, lighter fluid, fireworks, tear gas, oxygen bottles, and radio-pharmaceuticals.
There are special exceptions for small quantities (up to 70 ounces total) of medicinal and toiletry articles in your luggage, as well as certain smoking materials carried on your person.
