The Hazardous Material Regulations of the PHMSA/USDOT require a Shipper of a hazardous material (HazMat) to describe it on a shipping paper. Depending on the type of HazMat and the mode of transportation there may be a requirement for an additional description on the shipping paper (49 CFR 172.203). In a series of presentations I am researching and explaining each of these requirements for an additional description. This presentation looks solely at the requirement for an additional description for certain HazMat that meet the definition of an Elevated Temperature Material.

1. THE ADDITIONAL
DESCRIPTION ON THE
HAZMAT SHIPPING PAPER
One presentation in a series that briefly
explains the responsibility of the shipper
of a hazardous material to provide an
“additional description” on the shipping
paper if applicable.

3. Describing a Hazardous Material
• The Shipper of a hazardous material (HazMat) is
required to describe it on a shipping paper.
• The regulations detailing the hazardous material
description on a shipping paper are found at 49
CFR 172, Subpart C.
• An additional description of the HazMat may be
required on a shipping paper depending on the
hazardous material and the mode of
transportation.
@DanielsTraining 349 CFR 172.203(n)

4. 49 CFR 172.203 – Additional Description
(a) Special permits
(b) Limited Quantity
(c) Hazardous Substance
(d) Radioactive material
(e) Empty packaging
(f) Transportation by air

5. Describing an Elevated Temperature
Material on the Shipping Paper
If…
• A liquid meets the definition of an elevated
temperature material at §171.8 – Definitions.
And…
• The fact that it is an elevated temperature
material is not disclosed in the proper shipping
name.
• e.g. “Molten” or “Elevated temperature” are part
of the proper shipping name
@DanielsTraining 549 CFR 172.203(n)
Then…

6. Describing an Elevated Temperature
Material on the Shipping Paper
• “HOT” must
immediately precede
the proper shipping
name on the shipping
paper.
49 CFR 172.203(n) @DanielsTraining 6
HOT
3082

7. What Does it Look Like?
@DanielsTraining 749 CFR 172.203(n)
HM Basic Description
X
UN3082, Hot, Environmentally
hazardous substance, liquid, n.o.s., 9,
III, (contains water heated to a
temperature ≥212 °F)

8. More to Consider (1)…
Elevated Temperature Material defined at §171.8
• In a bulk packaging.
And…
• In a liquid phase & ≥100 °C (212 °F).
Or…
• In a liquid phase w/ a flash point ≥38 °C (100 °F),
intentionally heated & transported at or above its
flash point.
Or…
• In a solid phase & ≥240 °C (464 °F).
@DanielsTraining 849 CFR 172.203(n)
More on Elevated Temperature Material

9. More to Consider (1.1)…
Elevated Temperature Material defined at §171.8
• Even though the
definition of an
Elevated Temperature
Material at §171.8
includes a solid, the
requirement of
§172.203(n) only
applies to a liquid.
49 CFR 172.203(n) @DanielsTraining 9

10. More to Consider (2)…
Bulk Packaging defined at §171.8
• A bulk packaging has a
max capacity of:
• >119 gal for liquid.
• >882 lbs and >119
gal for a solid.
• >1,000 lbs water
capacity for a gas.
49 CFR 172.203(n) @DanielsTraining 10

11. 49 CFR 172.203(n) Verbatim:
(n) Elevated temperature materials. If a liquid
material in a package meets the definition of an
elevated temperature material in §171.8 of this
subchapter, and the fact that it is an elevated
temperature material is not disclosed in the proper
shipping name (for example, when the words
“Molten” or “Elevated temperature” are part of the
proper shipping name), the word “HOT” must
immediately precede the proper shipping name of
the material on the shipping paper.
