Performance-Oriented Packaging
Performance-oriented packaging (POP) was introduced into international packaging regulations in
1989. After 1991, POP was phased into the domestic regulations (49 CFR) and has been effective
since October 1, 1996. All nonbulk quantities of hazardous materials were required to be shipped
in POP. POP is packaging that meets design qualification testing. Package designs are subjected to
Drop, Stack, Vibration, Leakproofness, and Hydrostatic tests based upon United Nations recom-
mendations. A United Nations Certification marking may be applied to the packagings once the
design passes the performance tests (Figure 13.9).
Identification codes are set forth in the standards for packagings in 49 CFR Parts 178.504
through 178.523. A manufacturer must mark every packaging that is represented as manufactured
to meet a UN standard with other DOT-specified marks. The markings must be durable, legible,
and placed in a readily visible location. Packaging conforming to a UN standard must be marked
as follows:
1. The United Nations symbol as illustrated in Figure 13.9 or the letters “UN.” A packag-
ing identification code designating the type of packaging and material of construction.
2. A letter identifying the performance standard under which the packaging design type has
been successfully tested, as follows:
X for packagings meeting Packing Group I, II, and III tests
Y for packagings meeting Packing Group II and III tests or
Z for packagings only meeting Packing Group III tests
