Hazardous Materials
Carried by Airline Passengers and Crewmembers
49 CFR §175.10 Illustrated

In general, U.S. Department of Transportation (DOT) regulations prohibit passengers and crewmembers from carrying hazardousmaterials (dangerous goods) aboard commercial aircraft. The table below lists the exceptions that allow passengers and crewmembers
to carry a limited amount of hazardous materials in carry-on and/or checked baggage. Though allowable by DOT regulations (see 49
CFR, section 175.10), some of the items listed here may, at times, be prohibited/limited in the aircraft cabin by Transportation
Security Administration (TSA) security rules (see www.tsa.gov). Individual airlines and other nations may also have more restrictive
rules on what passengers can carry aboard the aircraft. See www.faa.gov/go/packsafe for additional guidance on hazmat in baggage.
