Here's a summary of DOT's container marking requirements. This would affect packaging that is coming in to your facility and going out. You should familiarize yourself with these requirements particularly if you ship regulated (hazardous, non-hazardous, and oil) wastes out in non-bulk containers.

Location of Container Manufacturer's Markings Manufacturers of DOT-prescribed containers are required to permanently mark them with the type of packaging, the name and address or symbol of the packaging manufacturer, or, where specifically authorized, the symbol of the agency certifying compliance with a UN standard. According to 49 CFR 178.3, on containers with a gross capacity of more than 66 pounds, the markings must appear on the top or on a side of the packaging.

Additional markings that are required depend on the container type. For example, non-bulk packagings for liquids must be marked with:
* UN symbol
* Packaging identification code
* Performance standard
* Maximum rated specific gravity
* Container origination
* Authorizing state (country)
* Minimum thickness for reuse (metal or plastic drums or jerricans)
* Test pressure in kilopascals

These markings are required to be placed in a permanent form on the bottom.

For additional marking requirements refer to 49 CFR 178-180
