CA 65 Introduction

Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The Proposition was intended by its authors to protect California citizens and the State‘s drinking water sources from chemicals known to cause cancer, birth defects or other reproductive harm, and to inform citizens about exposures to such chemicals. so, in theory, all products containing hazardous substances within the scope of its control, including but not limited to Electrical and electronic products, textile products, toys, food contact materials, jewelry products and home decor products.

CTI Suggestion

California‘s 65 does not set limit to the material. The limit of substances in the products should refer to the existing lawsuit aiming at this kind of product or agreement. Enterprise should compare the existing lawsuit of substances control requirements and focus on newly added substances and risky chemicals. In  order to reduce the risk of illegal, companies are suggested to conduct supply chain survey and perform test if necessary.

 

CTI Service

In recent years, the notification of being unable to comply with REACH regulation requirements is increasing, the published compendium on analytical methods for restrictions under REACH Annex XVII will help enterprises to better meet the requirements of REACH regulation, reduce the risk of the product being punished.
