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.
