changes to regulatory text language to eliminate confusion that these items may only be
able to be transported as cargo. PHMSA has revised the language in §§ 173.159a,
173.162, 173.175, 173.219, and 173.306 to be consistent with the language in special
provision A200 that these excepted articles, items and materials must be transported as
cargo and cannot be carried onboard an aircraft by passengers or crewmembers as carry-on
baggage, checked baggage, or on their person unless specifically excepted by § 175.10.
PHMSA received one comment from the FCHEA requesting that we amend §
175.10(a)(19) to allow fuel cell cartridges containing flammable gas in division 2.1 and
fuel cells containing water reactive materials in division 4.3 in checked passenger baggage.
PHMSA did not propose changes to the provisions allowing for the checking limited types
of fuel cells in the NPRM, and consider this request to be outside the scope of this
rulemaking.
Section 173.4b

exception in § 175.10(a)(22) to permit non-infectious specimens packaged in accordance
with § 173.4b(b) to be carried aboard an aircraft by passengers and crewmembers in
checked or carry-on baggage or on their person. In the NPRM we inadvertently neglected
to revise the language in § 173.4b(b)(8) to recognize this exception. In this final rule,
PHMSA is revising § 173.4b(b)(8) to reference the adopted exception in § 175.10(a)(22).
Section 173.12
This section specifies the exceptions for shipment of waste materials including the
requirements for waste packages known as “lab packs.” A lab pack, although not
