Reference No. 23-0071
Dear Ms. Shaffer:
This letter is in response to your August 18, 2023, letter requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the use of a comma in place
of a decimal point in the United Nations (UN) specification packaging marking when used for
describing the specific gravity on a packaging. In your letter, you provide an image of a United
Nations (UN) specification packaging marking and ask whether the decimal comma in “/Y1,6/”
is acceptable to represent the specific gravity of 1.6.
The answer is yes. The HMR do not specifically authorize or prohibit the use of the decimal
comma. Additionally, the decimal comma is commonly used in international commerce, and the
intent of the UN performance packaging system - to include the UN specification package
marking - is to facilitate both domestic and international commerce. Therefore, this Office would
not consider use of the decimal comma to be a violation of the provisions of the HMR.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Shane C. Kelley
Director,
Standards and Rulemaking Division

I’m of the opinion this is an acceptable internationally recognized format that introduces no safety
concerns, but welcome the comments of others on this chain. Unfortunately this may be a
discretionary area managed at the inspector level as - unless I am missing a cite my team can point to
- it is not specifically addressed. If an interp would help, and we don’t have one on record, the team
was just remarking to me today that the interp stack is getting low and we could use a new request or
two.

Good Afternoon PHMSA,
COSTHA is evaluating some outstanding inquires to PHMSA and we are following up on this

<<<PAGE 4>>>

request from November 2022.
A COSTHA member purchased UN specification packaging (specification mark pictured
below) that identifies the gross weight indicator with a European indicator of a “comma” and
not a decimal point (e.g., 1,6 vs. 1.6).
The member is concerned this packaging will not be accepted for transport and/or that US
inspectors (including FAA inspectors and thus airlines), may not recognize the gross weight
indicator with a European indictor of a “comma” and not a decimal point.
We were unable to identify any letters of interpretation to provide clear guidance.
Is this acceptable?
We appreciate your review and response.

Subject: PHMSA interpretation on European indicators for decimal place
Shane,
We have not found any letters of interpretation on the topic and nothing that provides any clear
guidance in 49 CFR.
Please take a look at the picture below:

<<<PAGE 6>>>

You will notice the tested gross weight of the package is indicated as 1,6. The are mean this to
indicate that it was tested and certified to 1.6 kg. However, they have used the European indication
for a decimal place.
Is this acceptable in the US? The member company that has purchased this package is very concerned
that US inspectors (including FAA inspectors and thus airlines), may not recognize the indicator and
thus would not accept it for transport.
Any direction would be greatly appreciated!

Dear Mr. Kelley:
The Council on Safe Transportation of Hazardous Articles, Inc. (COSTHA) requests a formal
letter of interpretation regarding the use of the European gross weight indicator of a “comma”
in place of a decimal point in a UN Specification packaging mark.
In the Hazardous Materials Regulations (HMR) §178.503(a)(4) states:
A designation of the specific gravity or mass for which the packaging design type
has been tested, as follows:
(i) For packagings without inner packagings intended to contain liquids, the
designation shall be the specific gravity rounded down to the first decimal but may
be omitted when the specific gravity does not exceed 1.2; and
(ii) For packagings intended to contain solids or inner packagings, the designation
shall be the maximum gross mass in kilograms;
…
COSTHA specifically requests an interpretation as to whether a package marking identifying
the gross weight indicator with a European indicator of a “comma” and not a decimal point
(e.g., 1,6 vs. 1.6) is authorized for use under the HMR.
For Example:
Jennifer Stokes
Regulatory Manager
Procter & Gamble
Wim Verkuringen
Director DG & Transportation Safety
Johnson & Johnson
Mike Wentz
COSTHA appreciates your review of this interpretation request, and we look forward to
hearing from you soon.
