Dear Mr.' Boutilier:
This is in response to your letter requesting clarification of
the requirements under the Hazardous Materials Regulations (HMR;
49 CFR Parts 171-180) regarding over-the-counter sales of
hazardous materials. You ask for additional clarification of our
response to a previous interpretation letter (Ref. No. 01-0290)
hazardous materials that do not meet the materials of trade
dated May 6, 2002. You state that your questions pertain to
exceptions in § 173.6 and that your employees are aware that the
customers are transporting hazardous materials in commerce. We
have framed our response in the following series of questions and
answers •
Q1. As part of our company training, is it acceptable to
instruct our employees not to provide a verbal interpretation of
the HMR, at the time of will call, when not asked by the
customer?
A1. The HMR do not require the offeror to provide an
interpretation of the hazardous materials regulations to the
extent that it may be appropriate with regard to over-the-counter
customer; nowever, we strongly encourage such actions to the
sales.
Q2. Is the seller required to include the total weight, shipper's
certification and
equired to
address of the recipient of the hazardous
materials on the shipping paper?
shipping paper as required by Part 172, Subpart C of the HMR,
paper, therefore, the offeror is responsible for providing a
that includes the total weight and shipper's certification.
offeror is not required to enter the recipient's (consignee's)
address on the shipping paper.

Q3. Is it acceptable to load over 1000 pounds of a Class 2
retrigerant gas onto a customer's vehicle and provide temporary
placaras, upon request, without verifying whether or not the
driver of the vehicle has a valid commercial driver's license
(CDL) with a hazardous materials endorsement?
A3. The HMR do not require the offeror to verify whether the
driver has a valid CDL with a hazardous materials endorsement,
04. Is the seller responsible for ensuring that the purchaser
has properly secured the hazardous materials into their vehicle
at the time of will call?
An offeror who loads hazardous material into a transport
vehicle must perform the function in conformance with the
the carrier is ultimately responsible for ensuring that the load
applicable requirements in Part 177. (See § 173.30.) However,
is properly loaded and secured before transporting the material
in commerce.
For your information, on March 25, 2003, a final rule was
published in the Federal Register (68 FR 14510) under Docket No.
RSPA-02-12064 (HM-232) requiring security awareness to be
included in all hazardous material employee training (see
§ 172.704 (a) (4)). In addition, persons who offer for
transportation or transport certain hazardous materials (see Part
172, Subpart I) must develop and implement security plans.
I hope this information is helpful. If you have additional
questions, please do not hesitate to contact this office.

Dear Mr. Mazzullo,
I am writing you in regards to your letter of interpretation to Mr. Romach (reference #
01-0290). Our company is Refrigeration Supplies Distributor, a wholesaler of
commercial refrigeration and heating products for the HVAC industry. Our customer
base is exclusive to licensed contractors who, for the purpose of this letter, "will call'
material in weights above the material of trade exceptions. This letter does not pertain to
our own deliveries or to those of a contracted carrier. The regulations that require
training for companies involved in the transportation of hazardous materials are well.
known among our industry. This has been the subject of multiple articles within our
trade publications. We are requesting further clarification to some of your responses to
Mr. Romach's questions, as well as, additional concerns that our company has pertaining
to our specific business situation. Our specific goal is to determine the legality of
drafting a disclaimer to our "will call' customers. One that would indicate that at the time
of the 'will call' of a hazardous material; the purchaser would become the shipper of the
hazardous material. The purchaser would then be subject to all of the regulations of the
HMR that would apply to a shipper transporting a hazardous material in commerce.
I am framing this next portion of our letter in a bullet format summary of questions taken
from Mr. Romach's letter, each directly followed by your response in italics. I am
including your responses as a point of reference for further clarification that will be
requested in the form of numbered questions of interpretation directly from our company.
• For the purpose of the materials of trade exceptions, who is responsible for
informing the operator of a motor vehicle of the requirements found in the HMR?
(Referring to 173.6)
"The motor vehicle operator's employer would be responsible for providing this
• information. However, in practice, it may be necessary for an over-the-counter sales
employee to be able to distinguish between those types and quantities of hazardous
materials that qualify for the materials of trade exceptions, and those that do not, in
order to determine whether the material of trade exemptions apply."

If the requirements of the materials of trade exceptions are not met for example,
the total quantity exceeds 440 pounds gross weight or an individual package is
larger than allowed), do the HMR apply to over-the-counter sales of hazardous
materials?
"Yes. The seller of hazardous materials over-the-counter is an 'offeror' who is
responsible for assuring that the materials are packaged, labeled, and described on a
•shipping paper as required by the HMR whenever the over-the-counter sales
employee knows (or has reason to know) that the customer will transport the
hazardous material in commerce (such as the customer is transporting the hazardous
material as part of a business). "
• Does the over-the-counter purchaser of hazardous materials become the shipper
• (offeror) responsible for compliance with the HMR when it takes 'ownership' of .
... i
the materials upon purchase?
"No. The status of an offeror does not depend on ownership. Under most circumstances,
the purchaser of hazardous materials over-the-counter is a carrier (or transporter) who
may not accept and transport hazardous materials that are not in compliance with
responsibilities of an offeror. "
Is an over-the-counter sales employee responsible for asking purchasers of
G.r.
hazardous materials whether they will be transporting the materials in commerce?
"The HMR do not require a person selling hazardous materials to ask specific questions,
but it may be appropriate under the circumstances of over-the-counter sales. The over-
the-counter sales employee must consider readily apparent facts that indicate a customer
will transport the purchased hazardous materials in commerce. The employee would not
be 'absent the knowledge' its customer will transport the purchased hazardous material
in commerce when a reasonable person would realize that the customer is purchasing the
hazardous material for use at (or delivery to) another location as part of any type of
....
bușiness enterprise."
Before, I move on to our own specific questions, it should be clear that our employees,
for the most part, would not be 'absent the knowledge" that our customers will be
transporting hazardous material in commerce. This is due largely to the fact that when
material is purchased in weights above the material of trade exceptions our employees
typically load it on our customer's vehicle as a service to our customers.
Q1 - As part of our company training, is it acceptable to instruct our employees to not
provide a verbal interpretation of the HMR, at the time of the will call, without being
...
prompted by our customers to do so? Furthermore, to not provide shipping papers,
placards, or material safety data sheets without first being requested to do so.

Q2 - Would it be acceptable to provide our 'will call' customers (not a contracted
carrier), upon request, with a pre-printed shipping paper listing the proper description of
the hazardous material, while excluding the 'ship to' address, weight totals, and
certification (signature)? Our position would be that our company would still be in
compliance with 173.22 of the HMR by ensuring that the materials have been properly
packaged, labeled, and described on a shipping paper. It would be the customer's
responsibility to record the 'ship to' address (this information would only be pertinent to
the purchaser), weight totals (there is always a possibility of more material already on
their vehicle at the time of will call), and finally the certification (signature), which in our
opinion due to the fact that they are not a contracted carrier, must be made by the
individual who has purchased and is transporting the hazardous material.

placards, upon request, without verifying whether or not the driver of the vehicle has in
their possession a valid commercial drivers license with a hazardous materials
endorsement?
Q4 - Would it be the responsibility of the seller to ensure that the purchaser has properly
secured the hazardous material onto their vehicle at the time of will call?
In closing, as stated before our main reason for writing this letter of interpretation is for
clarification regarding the legality of drafting a disclaimer to our customers. One that
would indicate that at the time of 'will call' of a hazardous material; the purchaser would
ecome the slupper of the hazardous material. The purchaser would then be subject to all
of the regulations of the HMR that would apply to a shipper transporting a hazardous
material in commerce.
Your response to our specific request and to our related questions would be greatly
appreciated.
