The Washington State Department of Ecology has issued a rule requiring manufacturers of toys, baby products, cosmetics, and jewelry to report whether their products contain certain harmful chemicals. The rule was issued under the authority of the Children’s Safe Product Act of 2008, which requires manufacturers to disclose chemicals of concern to children.

The rule identifies 66 chemicals that would trigger reporting to the state, including formaldehyde, bisphenol A, phthalates, benzene, toluene, and styrene. Large manufacturers, or those with gross sales exceeding $1 billion, must report to the state by August 2012. For smaller companies, the rule will be phased in over the next several years.
