Analyzed Economic Effects

More hazardous materials allowed
Several companies (for example, Weldship LLC (14784-M), Bollore Logistics USA Inc. (20274-M), Helicopter Applicators, Inc. (20275-M), and the City of Phoenix (21999-M)) applied to modify special permits so they can ship additional hazardous materials by motor vehicle, rail, vessel, or aircraft. These are requests to change the permits that govern who may move dangerous goods and how they are moved.
Limited-quantity shipping by Amazon
Amazon.com, Inc. (application 16413-M) asked to modify a special permit to authorize additional hazardous materials to be shipped as limited quantities by motor vehicle and rail (modes 1 and 2). This seeks permission to add more items eligible for limited-quantity shipment under that special permit.
New packaging and container approvals
Multiple applicants (for example, Hexagon Digital Wave LLC (20396-M), Zhejiang Meenyu Can Industry Co., Ltd. (21074-M), Bhiwadi Cylinders Private Limited (22025-M), and G-Shang Metal Corporation (21739-M)) asked to modify permits to authorize additional packagings, inner metal containers, inner receptacle designs, or new packaging designs including packagings homologated to UN/ISO 11515. These changes would allow use of those specific packaging designs under the modified special permits.
Non‑DOT cylinders and battery designs
Blue Origin, LLC (21890-M) applied to modify a special permit to authorize non‑DOT specification cylinders (modes 1 and 3), and Jaguar Land Rover Limited (22042-M) applied to modify a permit to authorize an additional battery design (modes 1 and 4). These permit changes would allow specified non‑standard cylinders and a specific battery design to be used under the permits.
Allow business‑to‑business air deliveries
Zipline International Inc. (22087-M) requested a permit modification to allow deliveries of hazardous materials from businesses to businesses using cargo aircraft only (mode 4). This is a request to permit business-to-business hazardous materials deliveries under that special permit.
Export full cylinders under limits
Resonac America, Inc. (21354-M) applied to modify a special permit to authorize the export of full cylinders under limited circumstances (modes 1 and 3). This would permit exporting fully filled cylinders in specific situations covered by the permit.
Clarify requalification marking rules
Versum Materials US, LLC (15660-M) applied to modify a special permit to clarify the requalification marking requirements (modes 1, 2, 3, 4, 5). This seeks to change the permit wording to make requalification marking rules clearer for the permit's scope.
Transport pressure vessel by cargo vessel
Daicel Safety Systems (Thailand) Company Limited (22064-M) applied to modify a special permit to authorize transportation of a pressure vessel via cargo vessel (modes 1, 2, 3, 4). This would allow that specific pressure vessel to be carried by ship under the modified permit.
