Specifically you ask if a material\ndescribed as \"Hydrogen, compressed, 2.1, UN 1049,\" is excepted from the specification\npackaging requirements under § 173.306(a)(1) if shipped by highway and cargo aircraft\nonly.\nUnder § 173.306(a)(1), a compressed gas placed in a non-specification container with a\nmaximum capacity of four fluid ounces (7.22 cubic inches) or less may be described and\ntransported as a limited quantity when it conforms with the provisions of this section.\nNote that the four fluid ounce (7.22 cubic inches) limit applies to the capacity of the\ncontainer, not the volume of material contained in the container. This section excepts a\nlimited quantity from labeling, unless offered for transportation by air, and from\nplacarding and specification packaging requirements under the HMR. The HMR permit\nthe shipment of Hydrogen, compressed by highway and cargo aircraft. Under the\nInternational Civil Aviation Organization's Technical Instruction for the Safe Transport\nof Dangerous Goods by Air, compressed hydrogen is authorized for transport aboard\ncargo aircraft in accordance with packing instruction 200 which permits cylinders other\nthan UN marked and certified cylinders, to be used if the design, construction, testing,\napproval and markings conform to the requirements of the appropriate national authority\nin which they are approved and filled.\nI hope this satisfies your request.\nSince:t~y;1.~_~\n1frtlll/~\nHattie L.

(I.E \\'Ve have a non-dot, non-un cylinder full of\nbydrogen but is less than 7.2 cc) as far as 1 can tell we can transport it I!ither by highway or cargo aircraft only but\nnot passenger aircraft or rail assuming all other parts of the HMR followed.?\n(a) Limited quantities of compressed gases for which exceptions are permitted as noted by reference to this section in\n§172.101 of this subchapter are excepted from labeling, except when offered for transportation or transported by air, and,\nunless required as a condition of the exception, specification packaging requirements of this subchapter when packaged in\naccordance with the following paragraphs. For transportation by aircraft, the package must also comply with the applicable\nrequirements of §173.27 of this subchapter and only hazardous materials authorized aboard passenger-carrying aircraft may\nbe transporteq as a limited quantity. In addition, shipments are not subject to subpart F (Placarding) of part 172 of this\nsubchapter. to part 174 of this subchapter except §174.24, and to part 177 of this subchapter except § 177.817. Each package\nmay not exceed 30 kg (66 pounds) gross weight.\n(1) When in containers of not more than 4 fluid ounces capacity (7.22 cubic inches or less) except cigarette lighters. Special\nexceptions for shipment of certain compressed gases in the ORM-D class are provided in paragraph (i) of this section.\n9/24/2009\n\n<<>>\n\nPage 20f3\nHazardous\nmaterials\nSymbolsll descriptions and\nproper shipping\nnames\n(8) II\n(9) II (10)\n..
