(k) Technical names for  - n.o.s. -  and
other generic descriptions. Unless otherwise excepted, if a material is described on a shipping paper by one of
the proper shipping names identified by
the letter  - G -  in column (1) of the
Section 172.101 Table, the technical name of
the hazardous material must be entered in parentheses in association

 - UN 1760, Corrosive liquid, n.o.s., (Octanoyl chloride), 8, II - , or  - UN 1760,
Corrosive liquid, n.o.s., 8, II (contains
Octanoyl chloride) - . The word  - contains -  may be used in association with
the technical name, if appropriate. For
organic peroxides which may qualify
for more than one generic listing depending on concentration, the technical name must include the actual
concentration being shipped or the concentration range for the appropriate
generic listing. For example,  - UN 3102,
Organic peroxide type B, solid, 5.2,
(dibenzoyl peroxide, 52-100%) -  or  - UN
3108, Organic peroxide type E, solid, 5.2,

Table, must have the technical name of
the toxic constituent entered in parentheses in association with the basic description. A material classed as Division 6.2 and assigned identification
number UN 2814 or UN 2900 that is suspected to contain an unknown Category A infectious substance must
have the words  - suspected Category A
infectious substance -  entered in parentheses in place of the technical name

under the criteria in Section 172.101(c)(11).
(iii) If the n.o.s. description for the
material (other than a mixture of hazardous materials of different classes

primarily responsible for the material
being included in the hazard class indicated.
(iv) If the n.o.s. description for the
material (which is a mixture of hazardous materials of different classes
meeting the definition of more than
one hazard class) contains the name of
the chemical element or group responsible for the material meeting the definition of one of these classes. In such
cases, only the technical name of the
component that is not appropriately
identified in the n.o.s. description shall
be entered in parentheses.
(l) Marine pollutants. (1) If the proper
shipping name for a material which is
a marine pollutant does not identify by
