A Prop 65 Crash Course: What You Need to Know (2026)

Prop 65, also known as the Safe Drinking Water and Toxic Enforcement Act, is a California law that requires businesses to notify consumers if their products contain any of the 900+ chemicals known to the state to cause cancer, birth defects, or reproductive harm. This law has been in effect since 1986, but its enforcement and the list of chemicals have expanded over the years, leading to increased visibility and controversy.

For tech companies, particularly those involved in consumer electronics and streaming devices, Prop 65 compliance is crucial, especially if they sell products in California or online to California residents. A Prop 65 warning on a product doesn't necessarily mean it's unsafe, but rather that the product contains a chemical that the state of California has identified as potentially hazardous. Companies like those in the streaming industry, which often rely on global supply chains, need to be vigilant about the materials and components used in their products to avoid Prop 65 warnings, which can impact consumer trust and sales.

As the list of chemicals under Prop 65 continues to grow and regulations evolve, tech companies should stay informed about compliance requirements and consider proactive measures to minimize the presence of listed chemicals in their products. To watch next: updates on Prop 65 enforcement, potential changes to the list of chemicals, and how tech companies adapt their product formulations and supply chain management to mitigate risks and maintain consumer trust.
