Whose responsibility is it to classify a product as a hazardous material?

The responsibility to classify a product as a hazardous material typically falls on the manufacturer or distributor of the product. They must evaluate the chemical composition and potential risks associated with the product to determine its classification under relevant regulations, such as OSHA or EPA guidelines. Additionally, regulatory agencies may provide guidance and oversight to ensure compliance and safety standards are met. Ultimately, accurate classification is crucial for proper handling, storage, and transportation to protect human health and the environment.
