SUMMARY: In this final rule, PHMSA is
amending packaging requirements in
the Hazardous Materials Regulations to
enhance compliance flexibility, improve
clarity, and reduce regulatory burdens.
Specifically, we are revising several
packaging related definitions;
provisions to allow more flexibility
when preparing and transmitting
closure instructions, including
conditions under which closure
instructions may be transmitted
electronically;
shippers to retain packaging closure
instructions;
language that will allow for a
practicable means of stenciling the ‘‘UN’’
symbol on packagings; and clarifying a
requirement to document the
methodology used when determining
whether a change in packaging
configuration requires retesting as a new
design or may be considered a variation
of a previously tested design. This final
rule also incorporates requirements for
construction, maintenance, and use of
Large Packagings.
DATES: Effective Date: October 1, 2010.
Voluntary Compliance Date:
Compliance with the requirements
adopted herein is authorized as of
March 4, 2010. However, persons
voluntarily complying with these
regulations should be aware that appeals may be received and as a result
of PHMSA’s evaluation of these appeals,
the amendments adopted in this final
rule may be revised accordingly.
The Final Rule is effective October 1, 2010 with a voluntary compliance date of March 4, 2010. The Final Rule can be accessed here (
