436 Waste Management Practices: Municipal, Hazardous, and Industrial
TABLE 13.3 (Continued )
Details of the HMT
Hazardous substances. Proper shipping names for hazardous substances are in Table 1 to Appendix A, 49 CFR §172.101.
Hazardous wastes. If the word “waste” is not included in the hazardous material description in Column 2 of the table,
the proper shipping name for a hazardous waste must include the word “Waste” preceding the proper shipping name of the
material. As an example, “Waste acetone” is an appropriate shipping name.
Mixtures and solutions. A mixture or solution not identified specifically by name, composed of a hazardous material
identified in the table by technical name and nonhazardous material, must be described using the proper shipping name of
the hazardous material and the word “mixture” or “solution.”
A mixture or solution not identified in the table specifically by name, composed of two or more hazardous materials in
the same hazard class, must be described using an appropriate shipping description (e.g., “Flammable liquid, n.o.s.”). The
name that most appropriately describes the material shall be used; for example, an alcohol not listed by its technical name
in the table shall be described as “Alcohol, n.o.s.,” rather than “Flammable liquid, n.o.s.” Some mixtures are more appro-
priately described according to their application, such as “Coating solution” rather than by an n.o.s. entry. The technical
names of at least two components most predominately contributing to the hazards of the mixture or solution may be
required along with the proper shipping name.
Column 3: Hazard Class or Division
Column 3 contains a designation of the hazard class or division corresponding to each proper shipping name, or the word
“Forbidden.” A forbidden material cannot be transported. This prohibition does not apply if the material is diluted or stabilized.
Column 4: Identification Number.
Column 4 lists the identification number assigned to each proper shipping name. Those preceded by the letters “UN” are
associated with proper shipping names considered appropriate for international transportation as well as domestic trans-
portation. Those preceded by the letters “NA” are associated with proper shipping names not recognized for international
transportation, except to and from Canada.
Column 5: Packing Group
Column 5 specifies one or more packing groups assigned to a material corresponding to the proper shipping name and
hazard class for that material. Class 2, Class 7, Division 6.2 (other than regulated medical wastes), and ORM-D materials,
do not have packing groups. Packing Groups I, II, and III indicate the degree of danger presented by the material is either
great, medium, or minor, respectively.
Column 6: Labels
Column 6 specifies codes which represent the hazard warning labels required for a package filled with a material con-
forming to the associated hazard class and proper shipping name, unless the package is otherwise excepted from labeling
by 49 CFR Part 173.
The first code indicates the primary hazard of the material. Additional label codes are indicative of subsidiary hazards.
Provisions in Section 172.402 may require that additional labels other than that specified in Column 6 be affixed to the
package.
Column 7: Special Provisions
Column 7 specifies codes for special provisions applicable to hazardous materials. The requirements of that special provi-
sion are as set forth in 49 CFR §172.102.
Column 8: Packaging Authorizations
Columns 8A, 8B, and 8C specify the applicable sections for exceptions, nonbulk packaging requirements and bulk pack-
aging requirements, respectively, in Part 173. Columns 8A, 8B, and 8C are completed in a manner which indicates that
“Section 173” precedes the designated numerical entry. For example, the entry “202” in Column 8B associated with the
proper shipping name “Gasoline” indicates that for this material conformance to nonbulk packaging requirements pre-
scribed in Section 173.202 is required. When packaging requirements are specified, they are in addition to the standard
requirements for all packagings prescribed in Section 173.24.
Column 9: Quantity Limitations
Columns 9A and 9B specify the maximum quantities that may be offered for transportation in one package by passenger-car-
rying aircraft or passenger-carrying rail car (Column 9A) or by cargo aircraft only (Column 9B), subject to the following:
• “Forbidden” means the material may not be offered for transportation.
• The quantity limitation is “net” except where otherwise specified.
