Specifically, you request clarification on the requirement to indicate the type of packages on a shipping paper, in accordance with § 172.202(a)(7), as it relates to transporting jet perforating guns (JPGs), shipped under the proper shipping name “UN0494, Jet perforating guns, charged, 1.4D. ” You ask what the package type should be to describe “UN0494, Jet perforating guns, charged, 1.4D” on a shipping paper, in accordance with § 172.202(a)(7). Unless a specific packaging method has been prescribed by the Pipeline and Hazardous Materials Safety Administration (PHMSA) on an EX approval or applicable Department of Transportation (DOT) special permit, JPGs are typically transported unpackaged under the provisions of § 173.62, Packaging Instruction US1. Because your JPGs are transported as unpackaged articles, there is no packaging type to indicate on your shipping paper, as would otherwise be required under § 172.202(a)(7). Therefore, it is the opinion of this Office that for unpackaged articles described in this scenario, it is permitted to provide an accurate descriptor of the articles in lieu of a packaging type for the requirements of § 172.202(a)(7)—examples include “jet perforating guns, ” “JPGs,” or “explosive articles. ” I hope this information is helpful. Please contact us if we can be of further assistance.

The number and type of packages must be indicated. The type of packages must be indicated by description of the package (for example, “12 drums”). Indication of the packaging specification number (“1H1”) may be included in the description of the package (for example, “12 1H1 drums” or “12 drums (UN 1A1)”). Abbreviations may be used for indicating packaging types (for example, “cyl.” for “cylinder”) provided the abbreviations are commonly accepted and recognizable. Specifically, we ship and transport UN0494, Jet perforating guns, charged, 1.4D daily as part of our business. Question 1: What does PHMSA believe is the best “type” of package that should be listed in the number and type column? The jet perforating guns are various lengths of pipe containing shaped charges, detonator cord and boosters. We believe pipe is not an accurate reflection of the material and it is not your typical cylinder under gaseous pressure. Question 2: Could we call it a “jet perforating gun” and abbreviate it as JPG? Your consideration of this request is appreciated. Please let me know if additional information is needed. I may be contacted at 346-302-1607 or joe.murphy@hunting-intl.com. Respectfully, Joseph Murphy Joseph Murphy Compliance Manager - **truncated:** false - **body characters:** 5262
