The bill amends Chapter 21A of the General Laws to implement regulations designed to minimize 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 emphasizes public health by requiring the department to test children's products. The bill also introduces civil penalties for manufacturers who violate these regulations, with fines for first offenses capped at $5,000 and repeat offenses at $10,000. Additionally, it requires the Department of Environmental Protection to publish lists of toxic chemicals and safer alternatives within 18 months and mandates a triennial report on toxic chemicals in children's products, aiming to enhance consumer safety and protect children from harmful chemical exposures.
