OEHHA Publishes Information Letter on Proposition 65 Warnings for Items Accompanying the Purchase of Consumer Goods

On December 8, 2025, the agency implementing California’s Proposition 65, the Office of Environmental Health Hazard Assessment (OEHHA), published an Information Letter stating that consumer product safe harbor warnings “apply to items that accompany the purchase of consumer goods, such as receipts, labels, tags, product stickers, shipping materials, packaging, and instructions/manuals, whether the purchase is made in person or online.” 

The Letter goes on to state that, “regardless of whether such items are themselves consumer products, any exposures they cause still result from a person’s ‘acquisition’ or ‘purchase’ of a consumer product and will thus be ‘consumer product exposures.’”

The Letter also includes a reminder that “it is important to note that a warning must be given before an exposure occurs,” such as by placing signs at or near cash registers, and that occupational exposures from workers handling receipts or shipping labels may also need to be considered.
