Who must comply with HM regulations regarding the packaging of hazardous materials?

The requirement for compliance with hazardous materials (HM) regulations regarding the packaging of hazardous materials primarily falls on any person or persons performing an offeror function. This includes individuals or entities involved in shipping or offering hazardous materials for transport.

The role of an offeror encompasses anyone who prepares a shipment of hazardous materials, ensuring that all aspects of the packaging, labeling, and documentation meet federal and international regulations. This compliance is essential to ensure safety during transport, protect the environment, and minimize risks associated with handling hazardous substances. It applies broadly, rather than being limited to any specific type of organization or individual, as all offerors share the responsibility of adhering to these regulations.

By contrast, the other choices limit the scope of compliance incorrectly. Federal agencies, individuals with training, or only manufacturers do not encompass the full breadth of who may be involved in the packaging and earlier stages of the transportation process for hazardous materials. Therefore, any individual or organization engaged in those activities must comply with the relevant HM regulations.
