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 CPR 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 (lATA) recommendations.
I hope this answers your inquiry. If you need additional assistance, please contact this office at
(202) 366-8553.
Sincerely,
~_s~~
Ben Supko
Acting Chief, Standards Development
Standards and Rulemaking Division

Dear To Whom it may concern:
Based on my understanding and my conversations with Mike Stevens and Andrew, I need to have clarification of the
issue on flying UN1162 Dimethydichlolrosilane. Per the highlighted information below, it seems that it wasn't intended
to be forbidden.
Please let me know if you need anything to help you process this letter of interpretation.
