Ref. No. 11-0252

Dear Ms. Zax:

This responds to your October 7, 2011 request for clarification on shipping "UN 1162, Dimethydichlorosilane, 3(8), PG II", by aircraft under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if this material was intended to be forbidden for air transport under the HMR.

In accordance with §§ 171.22(e) and 172.101, this material is currently forbidden for transportation by aircraft under the HMR, and cannot be shipped unless a special permit or other authorization to ship this material is obtained from the Associate Administrator (AA); even though it is authorized by the International Civil Aviation Organization (ICAO) Technical Instructions and the International Aviation Transport Association (IATA) recommendations.

I hope this answers your inquiry. If you need additional assistance, please contact this office at (202) 366-8553.
