New York has become the first state in the nation to require manufacturers to disclose all intentionally added ingredients on baby diaper packaging. NY State Senate Bill S2279C, which will become law no later than December 2025, applies to both disposable and reusable diapers and is intended to give parents critical information they currently lack about the ingredients and materials that go into diapers.
Under this new law, diaper packaging must clearly list all intentionally added ingredients in order of predominance. The list can either be printed on the packaging or affixed to it. The law does not mandate disclosure of contaminants, but it closes a major gap in transparency by requiring disclosure of every ingredient, which has until now been considered voluntary information. “Ingredient” is defined as an intentionally added substance.
Companies that fail to comply could face fines or removal of their products from store shelves. While implementation details are being finalized, consumer advocacy groups have called for rigorous enforcement of the new law to ensure compliance.
Policy experts expect other states to introduce similar legislation. Plus, companies are unlikely to sell a separate formulation or packaging just for the Empire State – what they sell in New York they’re likely to also sell in other states, too.
