49 CFR Ch. I (10–1–18 Edition) 

§ 172.101 

‘‘or’’ in italics indicates that there is a 
choice of terms in the sequence that 
may alternately be used as the proper 
shipping name or as part of the proper 
shipping name, as appropriate. For ex-
ample, for the hazardous materials de-
scription ‘‘Carbon dioxide, solid or Dry 
ice’’ either ‘‘Carbon dioxide, solid’’ or 
‘‘Dry ice’’ may be used as the proper 
shipping name; and for the hazardous 
materials description ‘‘Articles, pres-
surized pneumatic or hydraulic,’’ ei-
ther ‘‘Articles, pressurized pneumatic’’ 
or ‘‘Articles, pressurized hydraulic’’ 
may be used as the proper shipping 
name. 

(3) The word ‘‘poison’’ or ‘‘poisonous’’ 

may be used interchangeably with the 
word ‘‘toxic’’ when only domestic 
transportation is involved. The abbre-
viation ‘‘n.o.i.’’ or ‘‘n.o.i.b.n.’’ may be 
used interchangeably with ‘‘n.o.s.’’. 

(4) Except for hazardous wastes, when 

qualifying words are used as part of the 
proper shipping name, their sequence 
in the package markings and shipping 
paper description is optional. However, 
the entry in the Table reflects the pre-
ferred sequence. 

(5) When one entry references an-

other entry by use of the word ‘‘see’’, if 
both names are in Roman type, either 
name may be used as the proper ship-
ping name (e.g., Ethyl alcohol, 

see 

Eth-

anol). 

(6) When a proper shipping name in-

cludes a concentration range as part of 
the shipping description, the actual 
concentration, if it is within the range 
stated, may be used in place of the con-
centration range. For example, an 
aqueous solution of hydrogen peroxide 
containing 30 percent peroxide may be 
described as ‘‘Hydrogen peroxide, aque-
ous solution 

with not less than 20 percent 

but not more than 40 percent hydrogen 
peroxide’’ 

or ‘‘Hydrogen peroxide, aque-

ous solution 

with 30 percent hydrogen 

peroxide.

’’ Also, the percent sign (%) 

may be used in place of the word ‘‘per-
cent’’ when words in italics containing 
the word ‘‘percent’’ are used in addi-
tion to the proper shipping name. 

(7) Use of the prefix ‘‘mono’’ is op-

tional in any shipping name, when ap-
propriate. Thus, Iodine monochloride 
may be used interchangeably with Io-
dine chloride. In ‘‘Glycerol alpha- 
monochlorohydrin’’ the term ‘‘mono’’ 

is considered a prefix to the term 
‘‘chlorohydrin’’ and may be deleted. 

(8) Use of the word ‘‘liquid’’ or 

‘‘solid’’. The word ‘‘liquid’’ or ‘‘solid’’ 
may be added to a proper shipping 
name when a hazardous material spe-
cifically listed by name may, due to 
differing physical states, be a liquid or 
solid. When the packaging specified in 
Column 8 is inappropriate for the phys-
ical state of the material, the table 
provided in paragraph (i)(4) of this sec-
tion should be used to determine the 
appropriate packaging section. 

(9) 

Hazardous wastes. 

If the word 

‘‘waste’’ is not included in the haz-
ardous material description in Column 
2 of the Table, the proper shipping 
name for a hazardous waste (as defined 
in § 171.8 of this subchapter), shall in-
clude the word ‘‘Waste’’ preceding the 
proper shipping name of the material. 
For example: Waste acetone. 

(10) 

Mixtures and solutions. 

(i) A mix-

ture or solution meeting the definition 
of one or more hazard class that is not 
identified specifically by name, com-
prised of a single predominant haz-
ardous material identified in the Table 
by technical name and one or more 
hazardous and/or non-hazardous mate-
rial, must be described using the proper 
shipping name of the hazardous mate-
rial and the qualifying word ‘‘mixture’’ 
or ‘‘solution’’, as appropriate, unless— 

(A) Except as provided in 

§ 172.101(i)(4) the packaging specified in 
Column 8 is inappropriate to the phys-
ical state of the material; 

(B) The shipping description indi-

cates that the proper shipping name 
applies only to the pure or technically 
pure hazardous material; 

(C) The hazard class, packing group, 

or subsidiary hazard of the mixture or 
solution is different from that specified 
for the entry; 

(D) There is a significant change in 

the measures to be taken in emer-
gencies; 

(E) The material is identified by spe-

cial provision in Column 7 of the 
§ 172.101 Table as a material poisonous 
by inhalation; however, it no longer 
meets the definition of poisonous by in-
halation or it falls within a different 
hazard zone than that specified in the 
special provision; or
