Dear Mr. Shelley:
This letter is in response to your October 26, 2018, letter requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the classification
of explosives.
We have paraphrased and answered your questions as follows:
Ql. You ask who is responsible for classifying explosive and pyrotechnic substances and
articles in the United States.
Al. In accordance with§ 173.56 of the HMR, classification of Class 1· (explosive) materials
is the responsibility of the person who offers a new explosive and the examining agency
and is subject to PHMSA's approval. Section 173.56 of the HMR specifies that an
approval request must be submitted to the Associate Administrator of Hazardous
Materials Safety with a classification report recommendation from an authorized test lab
or a foreign competent authority approval that assigns a Division, compatibility group,
and shipping description. If PHMSA finds that the approval request meets the regulatory
criteria, the explosive will be approved in writing and assigned an EX number.
Q2. You ask whether the United States has an equivalent to Notified Bodies (NB; entities that
are approved to carry out tests and classify explosives and pyrotechnics in the European
Union).
A2. The answer is yes. Only approved examination agencies are permitted to carry out these
tests and make a recommendation for Division, compatibility group, and shipping
description. However, PHMSA ultimately approves the recommended classification, as
indicated by the assignment of an EX number.

Q3. A3. Q4. A4. QS. AS. Q6. A6. Q7. A 7. You ask whether manufacturers, suppliers and/or distributors are permitted to self-certify
products in the United States.
The answer is no. Self-certification is not permitted for Class 1 materials. Except for
explosives made under the supervision of a component of the Department of Defense
(DOD) or the Department of Energy (DOE), all new explosives must be approved by
PHMSA or-for fireworks-an approved third-party agency (e.g., fireworks certification
agency.)
In the event organizations are permitted to self-certify (see Q3), you ask for clarification
of the rules and quality checks they must abide by (i.e., audits, equipment calibration, test
standards, etc.)
See A3. Self-certification is not permitted for Class 1 materials.
You ask whether there have been recent discussions on the classification for transport of
Thermite (Iron Oxide and Aluminum).
'
There have been extensive discussions surrounding the transport classification of
thermites (broadly defined) and thermite derivatives.
You ask whether a Thermite composition that contains additional oxidizers, energetic
binders and fuels, such as magnesium (i.e., a Thermate ), would be classified under the
"practical pyrotechnic effect" in the UN test matrix figure 10.2 of the UN Manual of
Tests and Criteria. You further ask if there are any records of such classifications.
Thermites and Thermates would both provide a "practical pyrotechnic effect" as defined
by the UN Manual of Tests and Criteria. This Office is riot aware ofany public reports of
such test results available at this time.
You ask whether there have been any tests carried out in accordance with the UN series
of tests where Thermates were found to be more sensitive to dropping, thermal,
electrostatic discharge, friction, impact, pressure and effects of shelf life, similar to
Magnesium, Teflon, Viton (MTV) flare compositions.
There are no widely available public data on the performance of Thermates.
I hope this information is helpful. Please contact us if we can be of further assistance.

Questions for the US side of Dangerous Goods Classification and Testing
Dear Mr. Shane Kelley, Director, Standards and Rulemaking Division
As. the former director of the United Kingdom (UK) Explos.i. ves. Notified Body (ENB) and
responsible for process of setting up the pyrotechnics Notified Body (PNB) at the health
and safety laboratory (HSL) (part of the health and safety executive (HSE)) I have some
queries. which l hope you can assist me with. Based on my experience with the
European Union (EU) directives concerning dangerous goods which were then
implemented in UK law and the testing items to United Nations (UN) series of tests and
trans.port rules to the European Agreement concerning the lntema.ti.onal. Ca.rri.age of
Dangerous. Goods. by Road (A.DR) etc._
I have the following questions,
1
_
. Who in the United States (US) is responsible for classifying explosive and
pyrotechnic substances and articles similar to the ADR rules and in line with the and UN
series of tests for dangerous goods?
2. In the EU only Notified Bodies(NBs), which are quality systems approved, are
allowed to carry out the tests and classify explosives and pyrotechnics. Is this the same
in the US, i..e . . is. there an equivaJent to a Notified Body?
3. the US?
Are manufacturers, suppliers and or distributors allowed to self certify products in
4. If organisations are allowed to self certify, what are the rules and quality checks
put in pl.ace on them Le._ audits, equipment ca.Hbrati. on, test standards etc.,
5. As a member of the UK Institute of Explosive Engineers (and US based
International Society of Explosives Engineers) there have been recent discussions on
the classification for transport of Therrnite (l.ron Oxide and Aluminium). I wonder if there
have been any similar discussions in the US (in my research I did find Thermite with a
UN 4.3 Classification from a company in Texas)?
6. Also with the change from a Thermite to a Thermate i.e. a Thermite composition
with additional oxidizers, energetic binders and fuels such as magnesium, does the US
classify these under the 'practical pyrotechnic effect' in the UN test matrix figure 10.

and is there a record of any such product (article) or mixture (substance)
classmcations?
7. If there have been any tests carried out in accordance with the UN series of tests
were Thermates found to be more sensitive to dropping, thermal, electrostatic
discharge, fri
_ cti.on, impact, pressure and effects of sh.elJ life etc, similar to Magnesium,
Teflon, Viton (MTV) flare compositions?
