Requires menstrual products include ingredient list; requires toxic shock syndrome warnings be printed on tampon package.

New Jersey's S 2520, the "Feminine Hygiene Products Safety Act," requires all menstrual product packaging sold in the state to list every ingredient with its percentage and display clear warnings about toxic shock syndrome (TSS) on tampon packages. Specifically, tampon boxes must show a front warning with "DANGER" and a safety symbol, plus a detailed side/inside warning listing TSS symptoms, immediate actions (like removing the tampon and seeking care), absorbency advice, and alternatives. The law applies to all menstrual products (including pads, cups, and underwear) and takes effect seven months after enactment, with violations punishable as consumer fraud under state law. This directly affects manufacturers, sellers, and consumers by increasing product transparency and safety information.
