UN approved outer or single packaging is designated by a code comprising what information?

• A. A number indicating packaging, a capital letter indicating material of packaging, and a number indicating package category
• B. A letter indicating color, a number for weight, and a symbol for hazard
• C. A symbol code only
• D. A word and number

Answer: (A)

UN approved outer or single packaging carries a mark that encodes three specific pieces of information: the packaging type, the material of the packaging, and the package category (the performance level it has passed). The first element is a number that identifies the packaging design or type. The second element is a capital letter that indicates the material of the packaging. The third element is a number that designates the package category (the testing level the packaging meets). For example, a mark like 1A1 means packaging type 1, material A, and category 1. This standardized code lets shippers and inspectors quickly verify that the packaging meets the required UN testing and material criteria. The other options describe markings that don’t convey these three essential coded elements, so they don’t align with how UN packaging is identified.
