The bill amends Chapter 21A of the General Laws to implement regulations aimed at minimizing toxic chemicals in children's products. It introduces a new section that defines essential terms such as "children's product," "chemical," and "contaminant," while outlining the responsibilities of manufacturers, wholesalers, and retailers regarding products containing intentionally added perfluoroalkyl and polyfluoroalkyl substances (PFAS). The legislation prohibits the sale or distribution of children's products with intentionally added PFAS and requires manufacturers to notify the Department of Environmental Protection if their products contain any chemicals classified as high priority or of concern. The department is responsible for maintaining and regularly updating lists of these chemicals.

Furthermore, the bill mandates that manufacturers conduct hazard assessments for any substitutes for high-priority chemicals, ensuring that alternatives are less hazardous. It establishes a fee structure for administration and enforcement, allows for waivers under specific conditions, and requires manufacturers to recall non-compliant products while reimbursing retailers or purchasers. Civil penalties are set for manufacturers, with fines reaching up to $5,000 for first offenses and $10,000 for repeat offenses. The Department of Environmental Protection is tasked with publishing lists of toxic chemicals and safer alternatives within 18 months and submitting a report every three years on compliance and enforcement, emphasizing the importance of consulting authoritative chemical lists for comprehensive regulation and consumer safety.
