Reference No. 10-0081
Dear Mr. Thompson:
This is in response to your e-mail requesting clarification of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) regarding the use ofpunctuation marks.
Specifically, you ask whether a hyphen is required between the words "Poison" or "Toxic" and
the word "Inhalation" when the words "Poison Inhalation Hazard" or "Toxic Inhalation Hazard"
are required by § 172.203(m) to be entered on the shipping paper following the basic description.
The answer is no. The words can be entered with or without the hyphens. Also, for your
infonnation, § 172.101(c)(2) cited in your e-mail is specific to proper shipping names as entered
in Column (2) of the § 172.101 Hazardous Materials Table and specifies that punctuation marks
are not part of the proper shipping name and may be used, but are not required. The words
"Poison Inhalation Hazard" or "Toxic Inhalation Hazard" as specified in § I 72.203(m) are not
part ofthe proper shipping name, but are required infonnation that follows the basic description.
I hope this infonnation is helpful. Please contact this office should you have additional
questions.
Sincerely,
~F~--

in 172.101 (c)(2)it states Punctuation marks and words in italics are not part of the proper
shipping name J but may be used. In 172.203 (m)it states the words "Poison-Inhalation Hazard
or "Toxic-Inhalation Hazard"and the words Zone AJ 8J CJ or D shall be entered on the shipping
paper immediately following the shipping description.
I have a client that has an outside company provide a computered generated bill of lading. It
does not have a hyphen between Poison or Toxic Inhalation and they have a customer that
states there MUST be one there J Who is correct? Could I please get something in writing to
show what is the correct way? Thank you.
