Dear Mr. Ten Eyck:
This responds to your letter dated, requesting clarification of the inner packaging quantity
limitations for nitric acid under § 173. 158(b)(2), (d)(I), (d)(2), (e), (t)(2), (t)(3), (h)(l) and (h)(2)
of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask
whether the "not over 2.5 L" inner packaging quantity limitation as specified in the
above referenced paragraphs of the § 173.158 packaging instruction for nitric acid refers to
overflow capacity or nominal capacity while recognizing the latter to infer a certain amount of
outage manufactured into the packaging when necessary.
Nitric acid of 70% or less concentration offered for transport by rail, highway, or water may be
packaged in certain combination packagings with plastic, glass, or earthenware inner packagings
not over 2.5 L capacity each. The term "not over" as used in § 173.158 means that you may not
use an inner packaging with a maximum capacity greater than 2.5 L (i.e., overflow capacity).
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

Dear Susan:
TEN-E Packaging Services, Inc. is writing to request a clarification concerning maximum capacity for
2.5 liter glass and plastic bottles referenced in Sections 173.158(b)(2), (d)(1), (d)(2),(e), (f)(2), (f)(3) ,
(h)(1) and (h)(2) of Title 49 CFR. Does the statement "not over 2.5 L" used in these sections mean
overflow capacity or nominal capacity with a recognition for the latter that a certain outage can be
built into the packaging?
TEN-E Packaging Services would appreciate having the agency's viewpoint on this capacity matter.
