packages contained therein, except
that for a rigid overpack, the transport
index (TI) may alternatively be determined by direct measurement as prescribed in Section 173.403 of this subchapter
under the definition for  - transport
index, -  taken by the person initially
offering the packages contained within
the overpack for shipment.
(4) The category of Class 7 label for

the table in Section 172.403(c) using the TI derived according to paragraph (h)(3) of
this section, and the maximum radiation level on the surface of the overpack.
(5) The category of the Class 7 label
of the overpack, and not that of any of
the packages contained therein, must
be used in accordance with Table 1 of
Section 172.504(e) to determine when the
transport vehicle must be placarded.
(6) For fissile material, the criticality safety index which must be entered on the overpack FISSILE label is
the sum of the criticality safety indices of the individual packages in the
overpack, as stated in the certificate of
approval for the package design issued
by the NRC or the U.S. Competent Authority.

(b) Consolidated packaging. When two
or more packages containing compatible hazardous materials are placed
within the same outside container or
overpack, the outside container or
overpack must be labeled as required
for each class of hazardous material
contained therein, unless labels representative of each hazardous material

in the outside container or overpack
are visible.

motor carrier. Notwithstanding the provisions of paragraph (b) of this section,

(5) Packages must be secured within
the consolidation bin by other packages or by other suitable means in such
a manner as to prevent shifting of, or
significant relative motion between,
the packages that would likely compromise the integrity of any package;
(6) The consolidation bin must be
clearly and legibly marked on a tag or
fixed display device with an indication
of each hazard class or division contained within the bin;
(7) The consolidation bin must be
properly blocked and braced within the
transport vehicle; and
(8) Consolidation bins may only be
