What Does the UN Marking Mean?

A UN marking identifies key information about a container’s type, material, tested performance level, weight or specific gravity limits, testing country, manufacturer, and year of manufacture. These markings help determine whether the packaging is appropriate for transporting a specific material.

UN markings provide important information about the packaging's performance. A typical UN marking identifies:
  • The packaging type
  • The material of construction
  • The performance level
  • The maximum authorized weight or specific gravity
  • The country where testing was performed
  • The manufacturer
  • The year of manufacture
These markings help ensure that the packaging selected is appropriate for the material being transported.
