In 2025, Proposition 65 enforcement is tighter, more targeted, and more costly to ignore, especially for electronics brands.

From lead solder and flame retardants to vinyl acetate and bisphenol S, one unlabeled chemical can tank your product’s shelf presence and open the door to lawsuits.

Let’s break down what’s changed and what you must do to stay compliant.

What Triggers a Prop 65 Label for Electronics?

California Proposition 65 officially the Safe Drinking Water and Toxic Enforcement Act of 1986—requires clear warnings on any product that may expose consumers to one or more of the state-listed toxic substances.

In electronics, these exposures may come from:

  • Lead in solder joints or terminal finishes
  • Cadmium in resistors or board traces
  • Phthalates like DEHP, BBP, DBP, DIBP in cable insulation
  • Flame retardants in circuit board laminates or enclosures
  • Vinyl acetate, Bisphenol S (BPS), or Molybdenum trioxide in adhesives and coatings

If even trace amounts exceed Safe Harbor Levels—or if no exemption applies—a Prop 65 warning is required.
