Reference No. 10-0127
Dear Mr. La Porte:
This is in response to your letter requesting clarification of certain requirements under the Hazardous
Materials Regulations (HMR; 49 CFR Part 171-180) applicable to the transportation of "Gasoline,"
UN1203. Your questions are paraphrased and answered below.
Ql. Are shipments of Gasoline, UN1203 that are transported in packages greater than 8 gallons
required to be marked on one side of the package with "Gasoline, UN1203"?
AI. Non-bulk packages are required to be marked on one side of the package with the proper
shipping name (Gasoline) and identification number (UNI203) (see § 172.301). Non-bulk
packages have a maximum capacity of 450 L (119 gallons) or less as a receptacle for a liquid
(see § 171.8 for non-bulk packaging definition).
Bulk packages are required to be marked on each side and each end if the packaging has a
capacity of 3,785 L (1,000 gallons) or more, and on two opposing sides if the packaging has
a capacity of less than 3,785 L (1,000 gallons) for a liquid (see § 172.302). Bulk packages
have a maximum capacity greater than 450 L (119 gallons) as a receptacle for a liquid (see §
171.8 for bulk packaging definition).
Q2. Is the package required to be labeled with a Class 3, flammable liquid label?
A2. As specified in § 172.400, the following packages are required to be labeled: (1) A non-bulk
package; (2) A bulk packaging, other than a cargo tank, portable tank, or tank car, with a
volumetric capacity of less than 18 m
3 (640 cubic feet), unless placarded in accordance with
subpart F of this part; (3) A portable tank of less than 3785 L (1000 gallons) capacity, unless
placarded in accordance with subpart F of this part; (4) A DOT Specification 106 or 110
multi-unit tank car tank, unless placarded in accordance with subpart F of this part; and (5)
An overpack, freight container or unit load device, of less than 18 m3 (640 cubic feet), which
contains a package for which labels are required, unless placarded or marked in accordance

with § 172.512 of this part. Exceptions from the labeling requirements are specified in
§ 172.400a.
Q3. Are shipping papers required to be transported along with a material safety data sheet
(MSDS) for gasoline?
A3. Unless otherwise excepted, shipments of hazardous materials must be accompanied by
documents meeting the shipping paper requirements as specified in Subpart C of Part 172 of
the HMR. An MSDS is not required by the HMR and is a Department of Labor's
Occupational Safety and Health Administration (OSHA) requirement. However, shippers
may use the MSDS to satisfy certain HMR requirements, such as the shipping paper
requirements and the emergency response information requirements in § 172.602. If the
information on the MSDS meets the HMR requirements for shipping papers, including that
the required information must be either entered first, entered in a clearly contrasting color, or
identified by an "X" placed before the basic shipping description in a column captioned
"HM" (see § 172.201), the MSDS may be used to satisfy those requirements. As defined in
§ 171.8, a shipping paper means a shipping order, bill of lading, manifest, or other shipping
document serving a similar purpose and prepared in accordance with Subpart C of Part 172
of the HMR.
Q4. When is the driver of a hazardous materials shipment required to obtain a commercial drivers
license (CDL) with a hazardous materials endorsement?
A4. DOT's Federal Motor Carrier Safety Administration (FMC SA) issues the regulations that
require a driver who transports hazardous material shipments to obtain a hazmat endorsement
on a CDL, however, the requirement for a hazmat endorsement applies only to shipments for
which a placard is required under the HMR. CDLs and hazardous materials endorsements
are regulated by FMC SA in 49 CFR Part 383. Questions regarding FMCSA regulations
should be directed to the appropriate FMCSA field office. A list of FMCSA field offices and
contact information is available at
http://www.fmcsa.dot.gov/about/contact/offices/displayfield
roster.asp. or you may contact them at their headquarters offices in Washington, D.C. at 202366-6121.
Q5. Is a vehicle that is transporting Gasoline, UN1203 required to be placarded?
AS. Unless otherwise excepted from the placarding requirements, the answer is yes. Placarding
requirements can be found in Subpart F of Part 172. In § 172.504(e), Table 2 specifies a
flammable placard for Class 3 materials. Section 172.504( c) provides an exception from
placarding for Table 2 materials for shipments of non-bulk packages under I,OOllbs (454kg)
transported by highway or rail, however, the appropriate placard may be displayed regardless
of the exception.
Q6. Must "transporters" complete DOT hazardous materials training?

<<<PAGE 3>>>

A6. As specified in § 172.702, a hazardous materials employee that performs any function
subject to the HMR must meet the training requirements. You are not specific with your use
of the word "transporters," but a detailed definition of "Hazmat employee" may be found in §
171.S and includes a person who operates a vehicle used to transport hazardous materials.
07. What packagings are authorized for Gasoline, UN1203?
A7. The HMR sections that authorize packagings for Gasoline, UN1203 may be found in the
§ 172.101 Hazardous Materials Table (HMT) under the entry for Gasoline, UN1203 in
Column (SB) for non-bulk packagings (§ 173.202), Column (SC) for bulk packagings
(§ 173.242) and Column (SA) for packaging exceptions (§ 173.150).
I hope this information is helpful. Please contact this office if you need additional information.
Sincerely,
r-7~
