Dear Dr. Tohver:
This is in response to your letter dated May 1, 2004 regarding the transportation of pepper spray
aboard a passenger carrying aircraft under the requirements of the Hazardous Materials Regulations
(HMR: 49 CFR Parts 171-180). Specifically, you ask if you can pack a can of bear repellent pepper
spray in your checked baggage.
According to § 175.10(a)(4)(ii), a single container of self-defense spray, not exceeding 118 ml (4 fluid
ounces) by volume, that incorporates a positive means to prevent accidental discharge is not regulated
under the HMR and may be carried in checked baggage. The term "self-defense spray" is defined in
§ 171.8 (copy enclosed).
If your bear repellent pepper spray meets the definition of a self-defense spray, is packaged in a
discharge then, if permitted by the airline, a single can may be placed in your checked baggage. You
container with a volume not exceeding 4 fluid ounces, and has a positive means to prevent accidental
in your checked baggage.
should check with the airline before your trip to make sure that it will permit you to have pepper spray
I'hope this satisfies your request.
Sincerely,
040125
175.10
