There are 2 PHMSA interpretations out there that address this question.\u00a0 For example, the interpretation below states that an authorized single packaging for dangerous goods may contain inner receptacles that are compatible with the lading as long as it doesn\u2019t affect the performance of the specification packaging. The single packaging may remain marked as a single packaging and need not be retested. As long as the completed package meets the general packaging requirements of Part 173, Subpart B (see 173.21(e) and 173.24), this would be compliant.<\/p>\n<p>Similarly, this <a href=\"https:\/\/www.phmsa.dot.gov\/regulations\/title49\/interp\/06-0016\" target=\"_blank\" rel=\"noopener\">interpretation<\/a> says that the steel drum in question that is an authorized single UN packaging, may contain inner receptacles that are compatible with the lading as long as the inner receptacles would not adversely impact the level of performance of the packaging and that the packaging would still remain marked as a single packaging.<\/p>\n<p>Keep in mind that the closing instructions of the single packaging must still be closely followed, and you must still acknowledge the details of the UN specification marking that is associated with the single packaging, such as the rating (X, Y, or Z), total gross mass for solids, and the specific gravity for the liquids.\u00a0 In addition, be sure to review the appropriate regulations and packing instructions for whatever product you are looking to ship to determine if the UN packaging you are using is compliant.<\/p>\n<p>Here at ICC, we offer a wide array of both UN-rated combination and single packaging for your dangerous goods needs.
