Dear Mr. Woll:
•
This is in response to your February 23, 2005, letter requesting the regulations regarding
the transportation of undeveloped film aboard aircraft by passengers and crew members
under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Per your
request, enclosed are copies of 49 CFR 175.10 and 175.300.
I hope this satisfies your request.
Sincerely,
