Summarise this article

California’s OEHHA has updated Proposition 65 regulations to require businesses to name specific chemicals in warnings starting January 1, 2025, with a transition period ending December 31, 2027. These changes aim to enhance consumer transparency by replacing generic warnings with chemical-specific disclosures for endpoints like cancer or reproductive harm. The rules also introduce tailored requirements for industries such as food, automotive, and marine, and allow online compliance through product page warnings or hyperlinks. While these updates reduce over-warning and provide clearer information for consumers, businesses face higher compliance costs for updating labels and digital disclosures. Early action is recommended to minimize expenses and avoid legal risks.

What are the new requirements for Proposition 65 short-form warnings?

The updated Proposition 65 regulations mandate that businesses include the name of at least one chemical in short-form warnings. This ensures consumers are informed about specific exposures to listed chemicals known to cause cancer, reproductive harm, or both. The updated warning must also include specific phrasing such as "can expose you to [chemical]" to provide clearer context. These rules apply across multiple industries, including food products, motor vehicle parts, and recreational marine vessel components.

How can businesses ensure compliance with the updated Proposition 65 rules?

To comply with the revised Proposition 65 requirements, businesses should review their product labels and ensure warnings include at least one specific chemical name for each type of risk cited. For online sales, warnings must be clearly displayed on product pages or linked via an easily visible hyperlink labeled "WARNING" or "CA WARNING." Businesses are encouraged to begin adapting their processes during the three-year transition period, which ends on December 31, 2027. Products manufactured before January 1, 2028, with old warnings can continue to be sold without relabeling.

California’s Office of Environmental Health Hazard Assessment (OEHHA) has announced new regulations under Proposition 65, requiring updated short-form warnings that include specific chemical names. Approved on November 26, 2024, these changes aim to improve transparency and consumer understanding. Businesses must comply by January 1, 2025, with a three-year transition period ending on December 31, 2027.

What Are the New Proposition 65 Requirements?

The updated short-form warnings mandate the inclusion of at least one listed chemical for each endpoint, such as cancer or reproductive harm. Businesses can no longer rely on generic warnings. The new rules also apply to specific sectors, including food products, automotive parts, and recreational marine vessels.

Transition Timeline for Compliance

Businesses have until the end of 2027 to transition fully to the revised warnings. Products manufactured and labeled before January 1, 2028, can continue using old labels indefinitely. To ease the transition, the rules provide tailored options for various industries and address online sales by allowing warnings on product display pages or via hyperlinks.

What This Means for Businesses

The revised warnings are designed to reduce over-warning and enhance the accuracy of Proposition 65 disclosures. However, many businesses express concerns about the cost of compliance, which includes redesigning labels and updating digital warnings. Despite the challenges, the regulations grant flexibility with tailored warning formats for specific industries, such as automotive parts, recreational marine components, and food products.

Consumer Benefits from Updated Short-Form Warnings

By requiring businesses to name specific chemicals in warnings, OEHHA aims to empower consumers with the information they need to make informed purchasing decisions. The changes address longstanding complaints about the ambiguity of previous warnings. "These updates balance the need for consumer protection with practical solutions for businesses," an OEHHA spokesperson noted.

Preparing for the January 2028 Deadline

As the effective date approaches, businesses are advised to begin updating their warning labels and digital disclosures. With a three-year transition period, early action can minimise costs and ensure compliance, avoiding potential legal challenges.
