Dear Mr. Lezak:
This responds to your August 24, 2010 email requesting clarification of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180). Specifically, you request clarification ofthe marking
and labeling requirements for materials regulated as explosives that are transported from Canada into
the United States.
As specified in § 171.12(a), a hazardous material transported from Canada to the United States, from
the United States to Canada, or transiting the United States to Canada or a foreign destination may be
offered for transportation or transported by motor carrier and rail in accordance with the Transport
Canada TDG Regulations as authorized in § 171.22, provided the requirements in § § 171.22 and
171.23, as applicable, are met.
It should be noted that § 171.23(b)(4) requires that, prior to being transported within the United
States, explosive materials must be approved by the Associate Administrator in accordance with
§ 173.56 and that each package containing a Class 1 (explosive) material must conform to the
marking requirements in § 172.320.
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
/I

Subject: Shipments of explosives from canada to the US that have different transportation classifications
Ms. Herrera,
As previously discussed, have you received any feedback within your organization regarding the question below?
The US DOT and Natural Resources Canada both require explosive products to be classified by their agency before the
explosive can be transported in the US or Canada. Since we ship explosives from the US to our field locations in Canada,
the explosive must be classified by both the DOT and NRCan. It is common for an explosive product to be assigned one
classification in the US and a different classification in Canada. Shipping explosives from the US to Canada is not a major
problem because the Canadian authorities allow an explosive shipment from the US to enter Canada marked/labeled
with the US classifications until it has been received at the initial destination. After being received at the initial location,
ifthe classification is different, before being reoffered fortransport, the package must be remarked/labeled/shipped
according to the Canadian classification.
However, based on what has been communicated to me, currently there is not any provision in 49CFR that would allow
an explosive shipment from Canada to enter the US marked/labeled per the Canadian classification until it has been
received at the first stop. Can you offer any guidance on this matter? Please advise. If I should address this question to
another party within DOT, please provide me the contact information.
Best regards,
Paullezak
