The shipper is responsible for determining if a material meets the definition of a hazardous material. This responsibility is crucial because the shipper is typically the entity that prepares and offers the material for shipment, meaning they have the knowledge and understanding of the product's properties.

The definition of a hazardous material doesn't solely hinge on the nature of the material itself, but also on how it might interact with other materials and its potential impact on health and safety. Shippers must accurately classify the materials they are sending, complying with regulations that dictate how hazardous materials should be handled, packaged, and labeled.

This classification process is essential to ensure that the correct safety measures are implemented during transportation, which protects the public, the environment, and transportation personnel. Therefore, shippers play a pivotal role in the entire chain of custody for hazardous materials.

Other parties involved, like the employee handling the material, the transportation company, and government agencies, have different responsibilities related to compliance, transportation, and enforcement of regulations but do not hold the primary responsibility for determining the hazardous nature of materials.
