• Generic and n.o.s. names must include supplemental information as specified in the Dangerous Goods List, so that the dangerous good being transported can be properly identified.

Generic and “not otherwise specified” (n.o.s.) proper shipping names that are subject to special provision 274 or 318 in column 6 of the Dangerous Goods List must be supplemented with the technical or chemical group names. This does not apply if:

• It is a controlled substance, and
• A national law or international convention prohibits its disclosure.

For explosives of class 1, descriptive text may be added to the proper shipping name to indicate commercial or military names. Technical and chemical group names must be entered in brackets immediately following the proper shipping name.

The technical name must be:

• A recognized chemical or biological name, or
• Another name currently used in scientific and technical handbooks, journals, and texts.

Trade names must not be used for this purpose. For pesticides, use only:

• ISO common name(s),
• Other name(s) in the WHO Recommended Classification of Pesticides by Hazard and Guidelines to Classification, or
• The name(s) of the active substance(s).

When mixtures or articles containing dangerous goods are described by one of the n.o.s. or generic entries subject to special provision 274, not more than the two constituents that most predominantly contribute to the hazard or hazards need to be shown. This requirement does not apply to controlled substances when their disclosure is prohibited by national law or international convention.

If a package containing a mixture is labeled with any subsidiary hazard label, one of the two technical names shown in brackets must be the name of the constituent that compels the use of the subsidiary hazard label.

For proper documentation for n.o.s. entries classified as marine pollutants, the recognized chemical name of the constituent that most predominantly contributes to the classification as marine pollutant must be added to the proper shipping name. Exceptions to this are found in special provision 274.
