Since the regulatory changes were finalized August 2017 for implementation in August of 2018, the primary responsibility is on product manufacturers, producers, packagers, importers, suppliers and/or distributors. For consumer product exposures, businesses in the above categories must either provide a warning on the product, or provide notice and warning materials to “the authorized agent” for a retail seller and receive an acknowledgment that the notice and materials were received. The retail seller is responsible for placement and maintenance of the warning materials they have received.
