products which are essentially identical to those already exempted. SAAMI noted that
Cases, cartridge, empty with primer refers to small arms cartridges with no bullet or
propellant but with a primer, just an empty primed case. SAAMI stated that Cases,
cartridge, empty with primer of 50 caliber or less clearly meet the intent and equivalent
level of safety to products already referenced in 173.56(h).
PHMSA is amending §173.56(h) to ensure Cartridges for tools, blank that meet the
conditions of that paragraph are excepted from the requirements of the rest of this section.
PHMSA believes this to be a natural extension of the intent of the exception in §173.56(h)
as well as a necessary domestic change that is a direct result of international rulemaking.
PHMSA will not be adding Cases, cartridge, empty with primer to §173.56(h).
PHMSA believes Cases, cartridge, empty with primer to be materially different from those
articles currently authorized for the exception in §173.56(h). The proposed addition of
Cases, cartridge, empty with primer to §173.56(h) is also not a direct result of international
rulemaking and this rulemaking vehicle is not suited for such a proposal.
Section 173.59
Section 173.59 provides definitions of explosive terms related to the transport and
classification of explosives used throughout subpart C of part 173. These definitions are
intended for information only and are not to be used for purposes of classification or to
replace proper shipping names prescribed in § 172.101. In the UN Model Regulations,
Appendix B to Chapter 3 contains a similar list of explosive definitions which are also
intended for information only and are not to be used for purposes of hazard classification.
