An Act relative to menstrual product ingredient disclosure

This bill requires manufacturers selling menstrual products (like tampons, pads, cups, and underwear) in Massachusetts to disclose all ingredients on product packaging and online. Labels must list ingredients in order of predominance using visible 10-point font, and manufacturers must update both packaging and online disclosures when ingredients change. The law applies to all manufacturers whose products are sold in the state, with violations punishable by a $1,000 fine per offense. It takes effect 12 months after passage and supplements existing labeling requirements.
