addition to the proper shipping name.
The term "or in italics"
indicates that any terms in the sequence may be used as the proper
shipping name, when appropriate. Also as a general rule, the use of
the prefix "mono" is optional (for example, "monoethanolamine" is the
same as "ethanolamine"). The parenthetical designation of reportable
quantity (RQ) followed by a fraction (for example, RQ-1000/454)
indicates the minimum quantity of the material that is reportable, in
both pounds and kilograms (per the example, 1000 pounds or 454
kilograms). The RQ designations are descriptive but not technically
a part of the substance's proper name.
You will need to apply the
descriptive information later, in interpreting Column 5. Many other
rules to apply in using Column 2 are in CFR 49. At some point, you
will want to familiarize yourself with all of them.
Column 3 contains a designation of the DOT hazard class corresponding
to each proper shipping name or the word "forbidden" (which means
"prohibited from being offered or accepted for transportation"). If
you obtain new data on a material indicating that you may be able to
modify the "forbidden" designation or the hazard class specified for
a material specifically identified in the table, you should submit
the information to the Associate Director, Office of Hazardous
Materials Regulation, MTB.
Further details on how to interpret
Column 3 are in Section 172.101, CFR 49.
Column 3A lists the identification (ID) numbers assigned to hazardous
The North American (NA) designations are descriptions
that are not recognized for international shipments except those to
and from Canada. Those ID numbers preceded by a UN designation are
international and domestic shipments.
You will find more specific
information on reading Column 3A in CFR 49.
Column 4 specifies labels required to be applied to each package,
subject to additional labeling requirements found in Section 172.402,
The shipper is ultimately responsible for all labeling and
placarding; however, if you are initiating the movement, you will
need to know the proper label or placard types.
Column 5 discusses the applicable packaging section of Part 173,
Subchapter C, CFR 49.
You will note numerous exceptions from some
requirements of Subchapter C as you proceed to identify particular
packaging instructions. You can find these exceptions by referencing
By using both this column and Column 5b which lists
specific subparagraphs that you may need to reference to link the
parenthetical references listed by the proper shipping names with the
correct packaging modes, you should be able to properly pack the
materials you plan to transport.
