The document provides information on how to interpret UN designation numbers for packaging of hazardous materials. It explains that the number indicates the kind of packaging, letter indicates the material of construction, and another number indicates the category. It then provides examples of UN numbers for non-bulk and bulk packaging with explanations of each component. The summaries identify the key elements and purpose of the UN designation numbers in 3 sentences or less.
