proposed definition of Cartridges, blank. The definition proposed by SAAMI was
"Cartridges, blank. Articles that consist of a cartridge case with a center or rim fire primer,
with or without a confined charge of smokeless or black powder, but with no projectile.
Used in training, saluting, or in starter pistols, tools, etc." SAAMI’s proposal would
remove the requirement for Cartridges, blank to contain a confined charge of smokeless
powder. This SAAMI proposed definition is not consistent with the UN adopted
definition for Cartridges, blank. Additionally adopting the definition proposed by SAAMI
may conflict with the standing definition for Cases, cartridge empty with, primer. For the
aforementioned reasons, PHMSA is adopting the definition as proposed in the August 15,
2012 NPRM.

These packaging requirements stipulate the permitted inner, intermediate, and outer
packagings as well as any specific additional packaging information. These packaging
requirements are generally aligned with the requirements stipulated in the UN Model
Regulations.
In this final rule, PHMSA is revising various packaging provisions in the “Table of
Packing Methods” in this section to align with changes adopted in the 17th Revised
Edition of the UN Model Regulations. The revisions to the authorized packaging methods
provide greater flexibility when packaging explosives while retaining an appropriate level
of safety. These changes include, but are not limited to, permitting various explosives to
be transported in closed head drums in addition to the already permitted removable head
drums and adding the option to utilize wooden inner and intermediate packagings in
