Reference No. 17-0033

Dear Ms. Spaulding:

This letter is in response to your March 28, 2017, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the meaning of the word "container." Specifically, you ask whether "container" as used in § 173.306(a)(1) excludes other types of containers, such as aerosol cans.

The answer is no. The HMR do not specifically define the word "container." However, it is defined by Merriam Webster’s dictionary as, "one that contains [,] such as: a receptacle (such as a box or a jar) for holding goods." "Container" as it is used in § 173.306(a)(1) includes all container types (except cigarette lighters), such as aerosol cans, that comply with the requirements in § 173.306.

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