Also America is one of the most litigious countries in the world which is why toy safety is such a high prority. Even if a toy is clearly labeled ages 13 & up some dumb parent would give it to a 3year old and they would choke and the lawsuit would be immediate. They might even win it since toys are thought of as inheritently for children in America.
