Reference No. 18-0007

Dear Ms. Myers:

This letter is in response to your January 3, 2018, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to limited quantity markings. Specifically, you ask if it is permissible to mark a package with the limited quantity "Y" mark, which is designated for air transportation and authorized in § 172.315(b), if the package is transported by a mode other than aircraft. You also ask about additional requirements for the permissive use of this marking.

The answer is yes, provided the package meets all applicable limited quantity provisions and—in accordance with § 172.315(a)—conforms to the authorized substance and article provisions and the inner and outer package quantity limits detailed in § 173.27(f) of the HMR.

I hope this information is helpful. Please contact us if we can be of further assistance.
