Dear Mr. Lloyd:
This is in response to your letter of March 6, 1998, requesting clarification of marking
requirements for portable tanks in § 172.326(b) of the Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180). You question whether the marking of the owner's name on a
leased IM101 portable tank intended for export shipment satisfies § 172.326(b).
The answer is no. The name of the owner or of the lessee, if applicable, must be displayed
on a portable tank that contains a hazardous material (§172.326(b)). If a portable tank is
leased, the lessee's name must be marked on the tank. A leased tank makes the marking of
the lessee's name an applicable requirement.
I hope this answers your inquiry. If you need additional assistance, do not hesitate to contact
us.

Dear Mr. Mazzullo:
This letter will confirm an interpretation we received from your office on 6 March 1998
concerning the marking of the owner's or lessee's name on portable tanks (49 CFR 172.326(b)).
We asked for clarification as to whether the marking of the owner's name on a leased IM101
portable tank intended for export shipment satisfies the referenced regulation. We were advised
that the name of the lessee, instead, must be displayed on a leased portable tank.
situations involving leasing a tank, the rule requires the lessee's name to be marked on the
Apparently, the phrase "if applicable" in 172.326(b) refers to portable tanks under lease and, in
portable tank.
Please let us know if there is any additional clarification.
Very truly yours,
