Material safety, especially for products intended for children, is receiving increasing attention from the public and governments around world. Countries like the U.S., Canada, and regions like the EU passed various laws and regulations (eg. U.S. CPSIA and the European EN71) that impose strict restrictions on substances potentially hazardous to health.
We do all of our product material testing through well known 3rd party labs. You may click on http://www.cpsc.gov/cgi-bin/labapplist.aspx to see all testing labs accredited by the U.S. Consumer Product Safety Commission.
