authorized, except as may be provided by special provisions in Column 7. PHMSA
received one comment from SAAMI noting that PHMSA, unlike the UN Model
Regulations, IMDG Code and the European Road and Rail Regulations (ADR), did not
propose a limited quantity exception for UN 0055 "Cases, cartridge, empty with primer" as
a limited quantity. This was an inadvertent omission and PHMSA is adding 63 to column
8a of the HMT for the UN 0055 entry.
Amendments to the Column (9) quantity limitations.
Section 172.101(j) describes Column (9) of the HMT and the quantity limitations
for specific entries in the HMT. Furthermore, Columns (9A) and (9B) specify the
maximum quantities that may be offered for transportation in one package by passenger-
carrying aircraft or passenger-carrying rail car (Column (9A)) or by cargo-only aircraft
(Column (9B)). Unless otherwise indicated the quantity limitations shown in column (9) of
the HMT are net. PHMSA is removing the gross weight indicator in columns (9A) (if
authorized previously) and (9B) for the following battery entries. The quantity limit for
these entries should be based on the weight of the battery or batteries and not the weight of
the battery or batteries plus the packaging (i.e., the package).
