Reference No. 17-0138
Dear Mr. Shimko:
This letter is in response to your December 1, 201 7, email requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the de minimis
exception found in§ 173.4b. Specifically, you seek clarification of the de minimis exception as
it pertains to the HM-215J/224D final rule published January 14, 2009 [74 FR 2200] and certain
international standards, including the International Civil Aviation Organization's (ICAO)
Technical Instructions (TI) for the Safe Transport of Dangerous Goods by Air and the
International Maritime Dangerous Goods (IMDG) Code.
We have paraphrased and answered your questions as follows:
Ql. You ask whether Division 6.1, PG I (oral and dermal toxicity only) materials are eligible
for the de minimis exception in§ 173.4b.
Al . The answer is no. Only PG II and III materials are eligible for the de minimis exception
in§ 173.4b.
Q2. You seek confirmation of your understanding that the de minimis exception in § 173 .4b
does not align with the ICAO TI and IMDG Code. You further ask if this was the
Pipeline and Hazardous Materials Safety Administration's (PHMSA) intent.
A2. Your understanding is correct. The ICAO TI and IMDG Code currently allow
Division 6.1, PG I materials with the excepted quantity provision "E5" to take the
de minimis exception.
The HM-215J/224D final rule revised§ 173.4 and created two new sections: Excepted
quantity in§ 173.4a and De minimis in§ 173.4b. Section 173.4b was created by moving
§ 173.4(e) to its own section. Section l 73.4(e) was created by the HM-218D final rule,
published January 28, 2008 [73 FR 4699] in response to a petition that requested the
exception for PG II and III materials only. The HM-215J/224D final rule did not propose

a change to this applicability. PHMSA received no comments on this change and,
therefore, adopted the provisions as proposed.
If you believe a rulemaking change-such as a revision, addition, or deletion-is
warranted, we invite you to file a petition for rulemaking in accordance with §§ 106.95,
106.100, and 106.105 of the HMR, including all supporting information. Your request
will be evaluated for merit to be addressed in an upcoming rulemaking. For regulations
in 49 CFR Parts 171-180, submit the petition to: Standards and Rulemaking Division,
Pipeline and Hazardous Materials Safety Administration, PHH-10, U.S. Department of
Transportation, East Building, 1200 New Jersey Avenue, SE, Washington, DC 20590-
0001. Please contact Mr. Steven Andrews in the Regulatory Review and Reinvention
Branch of the Standards and Rulemaking Division at 202-366-8553 for more information.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely, ~

Subject: Request for Interpretation I De Minimis Exceptions
lnterp Application
I would like to request an interpretation in regard to De minimis Exceptions as stated in §173.4b. Specifically on
whether a Division 6.1, packing group I is permitted under this exception.
The current text in §173.4b(a) implies that only substances of packing group II or Ill of a division 6.1 are permitted to be
offered under the de minimis exceptions. Current International Standards as published in the UN Model Regulations
(Part 3, Chapter 3.5 (3.5.1.4)), ICAO Tl (Part 3, Chapter 5, (5.6)) and the IMDG Code (Part 3, Chapter 3.5, (3.5.1.4) do
allow the offering for transport of division 6.1, packing group I substances under such an exception. It is noted that the
ICAO Tl refers to this exception as De Minimis Quantities and the UN Model and IMDG Code use no specific title to this
exception within their applicable sections.
In researching previous rule makings as communicated in my email below to Mr. Shane Kelley and the attached files, it is
believed that division 6.1, packing group I materials were to be permitted under the De minimis exceptions. When 49
CFR was being amended under Final Rule HM-224D, 215J dated January 14, 2009 this change may have been in error
and was not the intended outcome.
I look forward to your reply.
Thank you,

Subject: De Minimis Exceptions
Hi Shane,
I hope you are doing well.
I want to ask you about some historical rulemaking as it relates to De Minimis Exceptions. I am writing to you since you
were involved with Final Rule HM-224D I HM-215J issued in January 2009. I am also referencing the working paper
submitted to the UN Sub-Committee by the U.S. in September 2009 (copy attached).
What is driving the question is the ability to offer a Class 6.1, PG I (oral or dermal toxicity) under the De Minimis
exceptions. As written today in 173.4b, only PG II or PG Ill is permitted, this is currently not harmonized with the
international standards. I believe this may not have been the intended outcome and that such a classification should be
allowed.
In the Final Rule PHMSA made changes to 173.4 (Small Quantity Exceptions) and created new sections 173.4a and
173.4b. Under the old 173.4 a Class 6.1 PG I was permitted. In the preamble to the Final Rule PHMSA stated:
We believe that aligning the existing small quantity provisions in the HMR with the excepted quantity provisions for air
and vessel transportation will enhance harmonization and increase safety.
We also are moving the exception for small quantities-less than 1 gram for solids and less than 1 milliliter for liquids per
inner packaging currently found in§ 173.4(e)-to a new§ 173.4b. This will align the requirements of the HMR with those
of the /CAO Tl and the IMDG Code for transport by air and vessel,
When we also look at the working paper to the UN, in paragraph 5.(a) the U.S. states:
Informal document UNISCETDG/35/INF. 59 suggested that as a starting point, the acceptable hazard classes
and divisions could include: Class 3, Class 4, Divisions 5.1 and 6.1, Class 8, and Class 9 ......... ..... Further, it is
believed that except for Division 6.1 (oral and dermal hazards) packing group I substances should not be
included in this provision ... ............ this proposal would allow de minimis exceptions for minute quantities of
Division 2.2 (no subsidiary risk), Class 3, Class 4, Division 5.1 Division 6.1 (oral and dermal hazards only),
Class 8, and Class 9.
The Table in this working paper also provides indication that a Class 6.1, PG I is allowable.
As referenced earlier, the current 173.4b allows only PG II and PG Ill substances under the De Minimis exceptions which
is currently not harmonized with the international standards. Based on the Final Rule and working paper it appears the
intent of harr:nonization was the objective but the outcome was not.
