Dear Mr. Willson:

This is in response to your letter dated September 9, 1998, concerning the gross weight marking on a specification packaging under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you ask if packages may contain less weight than the gross mass which is marked on the packaging.

Section 178.503 specifies the markings which must appear on a UN standard packaging.  For packagings intended to contain solids or inner packagings, the designation of the mass of the packaging must be the maximum gross mass in kilograms for which that packaging has been tested (178.503(a)(4)(ii)).  The gross weight of the package must not exceed the maximum gross mass printed on the box.  Therefore, packagings may contain materials in amounts less than specified in the printed markings.

I hope the satisfies your request.
