Dear Mr. Gramer:
This is in response to your letter regarding the orientation arrow markings that are required on certain
packages of liquid hazardous materials under the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171-180). Specifically you ask whether § 172.312 prohibits the placement of arrows for
purposes other than orientation on packages containing liquid hazardous materials.
The answer is yes. As provided by § 172.312, each non-bulk combination package having inner
packagings containing liquid hazardous materials must be packed with closures upward, and legibly
marked with package orientation markings. Additionally, arrows for purposes other than indicating
proper orientation may not be displayed on a package containing a liquid hazardous material.
I hope this information is helpful.
Sincerely,
When Hills,

Request for Interpretation concerning the use of up-arrows": 6Augl 998
Dear Mr. Mazzulio.
'orientation arrows' on combination packages containing liquid dangerous goods (hazardous materials) in
It is our understanding that the Hazardous Materials Regulations (FIMR) do not allow placement of
violation of the HMR. according to 49CFR172.312, and at best is misleading to dangerous goods package
articles or containers which have no 'upward' orientation. To display such marking appears to be a
handlers for whom the arrows are intended.
In 172.312(b) we see that for liquid dangerous goods packages, "... arrows for purposes other than
indicating proper package orientation may not be displayed...", 172.312(a)(1) specifically requires liquid-
carrying dangerous goods packages to be oriented, or "...packed with closures upward" during transport.

In 172.312 (c) orientation arrows are generally required on combination packages of liquid-carrying inner

reguirement seems self-evident - these types of packages have no such 'closure orientation'. As paragraphs

would be incorrect.
Further, it seems that to label these packages as such could be misleading to handlers of the package as is the
concern in paragraph (b). To apply arrows to such packages would not be for proper orientation of the
inner closures (none exist), and thus may be "...for purposes other than indicating proper package
orientation" and therefore may "... not be displayed..." [172,312(b)]. This seems to mean displaying such
arrows would not be "optional". as may be the case of small quantity exceptions stated in (c)(2) and (3).
