Dear Mr. Lopez:
This is in response to your July 19, 2004 letter concerning the
shipping paper requirements of the Hazardous Materials
paraphrased and answered
Regulations (HMR; 49 CFR Parts 171-180). Your questions are
as follows:
Q1:
does not include parentheses around the subsidiary hazard
Despite the example provided in § 172.202 (a) (2) (iii), which
class or division number, must the subsidiary hazard class
or division number appear in parentheses on the shipping
paper?
A1:
Except for combustible liquids, the subsidiary hazard
classes) or subsidiary division number (s) must be entered
in parentheses immediately following the primary hazard
class or division number.
The examples in
§ 172.202 (a) (2) (iii) should be corrected by placing
parentheses around the subsidiary class(es) and division
number (s). This error will be addressed in a future
rulemaking.
Q2:
Does the shipper have the option of using the subsidiary
hazard class or division number (e.g., (5) or (5.1) for an
oxidizer) on a shipping paper?
A2:
No.

Dear Mr. Mazzullo,
This is in regard to an apparent inconsistency in the Hazardous Materials Regulations.
49 CFR, §172.202 (a)(2) states:
The hazard class or division number prescribed for the material, as shown in Column (3)
of the Sec. 172.202 Table. Except for combustible liquids, the subsidiary hazard classes)
or subsidiary division numbers) must be entered in parentheses immediately following
the primary hazard class or division number.
However, the example in §172.202 (a)(2)(iii) does not list the subsidiary classes or division
numbers in parentheses, as follows:
For domestic shipments, primary and subsidiary hazard class or division names may be
entered following the numerical hazard class or division or following the basic
description. For example, ''Oxygen, compressed, 2.2 (non-flammable, non-poisonous
compressed gas), 5.1 (oxidizer), UN1072," or "Oxygen, compressed, 2.2, 5.1, UN1072,
(non-flammable, non-poisonous compressed gas) (oxidizer)";
Will you please clarify whether subsidiary classes or division numbers must be entered in
parentheses.
In addition, $172.202 (a)(2) gives an option as to whether class or division numbers must be
(5), UN1072" omitting the division number for "oxidizer?"
listed. Accordingly, is it your intent that oxygen may be listed as, "oxygen, compressed, 2.2,
Sincerely.
