What Is California Proposition 65?

California Prop 65 is a law intended to protect the State’s residents and drinking water sources from toxic chemicals and to inform its citizens about exposure. The State has published a list of over 950 naturally occurring and synthetic chemicals that are known to cause cancer, birth defects, or other reproductive harm. Violations for non-compliance may result in delays, lawsuits, fines, and recalls – all of which are avoidable with proper testing. Our California Prop 65 testing services evaluate your product against this list.

While Cal Prop 65 does not expressly prohibit the sale of products containing its listed chemicals, it does require the manufacturer to provide a "clear and reasonable" warning if a product’s content of a listed chemical exceeds the "safe harbor level." In the event that labeling is required for your product, our experts will guide you through the process from start to finish to help you achieve total regulatory compliance.

What Does Our California Prop 65 Testing Cover?

California Prop 65 applies to all consumer products sold in the state of California.

Our experts will test your products for listed chemicals and advise you on achieving Prop 65 compliance. We have expertise in a wide variety of product categories, including, but not limited to:

Your product will undergo a cultivated testing methodology, resulting in your product’s full compliance:

  • Review - an expert toxicologist will review the raw materials that have been disclosed in your product and compare it to the Prop 65 list of chemicals of concern.
  • Assessment - If any chemicals of concern are found in your products, a chemical assessment will be performed that will determine whether or not safe exposure levels are found under certain conditions.
  • Report - a report is generated for you and if unsafe levels of harmful chemicals are found, we will guide you through the labeling and corrective action process to bring your product into compliance.

Our process is continuously updated to follow any changes to California Prop 65, including any new chemicals added to the inventory.
