name may be selected when only domestic
transportation is involved.
W Means the entry is subject to the regulations
only when offered or intended for transport
by water, unless it is a hazardous substance
or waste or a marine pollutant.
Column 2 shows proper shipping names and
descriptions of regulated materials. Entries are in
alphabetical order. Use the name of the material
on the shipping paper—it must be the proper
shipping name. The Hazardous Materials Table
shows proper shipping names in regular type. The
entries that are in italics are not proper shipping
names. A shipper may only use them in addition
to the proper shipping names.
Column 3 shows each material’s hazard class or
division, or the word “Forbidden.” Never transport
a material that is forbidden. A material’s hazard
class or division is the key to using placards. You
can decide which placards to use if you know
these five things:
• Material’s hazard class or division.
• Special provisions.
• Amount being shipped.
• Total amount of weight of all hazard classes
loaded on your vehicle.
• Type of packaging (i.e., drum versus cargo tank)
Column 4 shows each material’s ID number. ID
numbers are preceded by the letters “UN” or “NA.”
The letters “NA” are associated with proper shipping
names that are only used within the United
States and to and from Canada. The identification
number must appear on the shipping paper as part
of the shipping description and also appear on the
package. It also must appear on cargo tanks and
other bulk packaging. The number is used by police
and fire crews to quickly identify the material after
a collision.
Column 5 shows each material’s packing group.
Packing groups indicate the degree of danger presented
by the material. The shipper is responsible
for determining the appropriate packing group.
- 114 -
Note: Classes 2, 7, and ORM-D materials do not
have packing groups assigned.
Column 6 shows the label(s) shippers must put on
packages of hazardous materials. Where the word
“none” is shown, no label is needed. The rules
require more than one label for some products.
Column 7 shows special provisions which may
be required by 49 CFR 172.102 for the item being
shipped. These special provisions may require
specific additional and/or alternate requirements
(e.g., packaging, handling, marking, etc.).
Column 8 is a three-part column showing the section
numbers covering the packaging requirements
for each hazardous material.
Note: Columns 9 and 10 do not apply to highway
transportation.
Appendix A, §172.101—The List of Hazardous
Substances and Reportable Quantities (RQ).
The Department of Transportation (DOT) and the
Environmental Protection Agency (EPA) monitor
spills of hazardous substances, which are named in
the List of Hazardous Substances and Reportable
Quantities. Any spill of an RQ hazardous substance
must be reported by telephone. Refer to pages 127
and 128 for additional information.
This list shows each product’s RQ. Carriers must
report spills from packages containing a quantity
equal to or greater than the RQ for that product.
The shipper identifies these materials as hazardous
substances by entering the letters “RQ” on the
shipping paper either before or after the basic
shipping description.
Appendix B—Marine pollutants are contained
in Appendix B of The Hazardous Materials Table.
These materials are regulated in interstate and
intrastate commerce in bulk quantities only and
may require special vehicle markings.
the shipping paper
The shipping paper shown in Figure 9-4 describes
a hazardous materials shipment. It must include:
• Page numbers if the shipping paper has more
than one page. The first page must tell the total
number of pages. For example: “Page 1 of 4.”
