TABLE 13.3
Details of the HMT
Column 1: Symbols
Column 1 of the table contains six symbols (“ ”, “A”, “D”, “G”, “I”, and “W”) as follows:
A Restricts the application to materials offered or intended for transportation by aircraft, unless the material is a
hazardous substance or a hazardous waste.
D Identifies proper shipping names which are appropriate for describing materials for domestic transportation but may
be inappropriate for international transportation under international regulations (e.g., IMO and ICAO). An alternative
proper shipping name may be selected when either domestic or international transportation is involved.
G Identifies proper shipping names for which one or more technical names of the hazardous material must be entered
in parentheses, in association with the basic description (see Sec. 172.203(k)).
I Identifies proper shipping names which are appropriate for describing materials in international transportation. An
alternative proper shipping name may be selected when only domestic transportation is involved.
W Restricts the application to materials intended for transportation by vessel, unless the material is a hazardous sub-
stance or a hazardous waste.
If none of the above symbols appears in the table, the substance is regulated for all modes of transportation.
Column 2: Hazardous Materials Descriptions and Proper Shipping Names
Column 2 lists the descriptions of the hazardous materials and proper shipping names of materials designated as haz-
ardous materials. Proper shipping names are limited to those shown in Roman type (not italics).
