packaging label.

3. A designation of the specific gravity or mass for which the packaging design type has
been tested.
4. The last two digits of the year of manufacture. Packagings of types 1H and 3H must also
be marked with the month of manufacture.
5. The state authorizing allocation of the mark. The letters “USA” indicate that the pack-

8. The rated capacity of the packaging, expressed in liters, may also be marked.
Performance-Oriented Packaging Standards for Nonbulk Packagings
Identification codes for designating non-bulk packagings consist of the following (Section 178.502):
A numeral indicating the kind of packaging:

1 drum
2 wooden barrel
3 jerricans
4 box
5bag
6 composite packaging
7 pressure receptacle
A capital letter indicating the material of construction:
A steel (all types and surface treatments)
B aluminum
C natural wood
D plywood
F reconstituted wood
G fiberboard
H plastic
L textile
M paper, and multiwall
N metal (other than steel or aluminum)
P glass, porcelain, or stoneware
A third numeral provides additional packaging details. For example, for steel drums (“1A”),
“1” indicates a nonremovable head drum (i.e., “1A1”) and “2” indicates a removable head drum
(i.e., “1A2”).
