Oehha has proposed to adopt a No Significant Risk Level (NSRL) of 27 micrograms per day for styrene. The NSRL represents the safe harbour level below which warning is not required under Prop 65. Warning for exposure to styrene will be required one year from the date it was listed.

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.
