Aren’t things made out of yarn exempt from CPSIA?
Yarn is one of the materials that was named in CPSC’s rulemaking document exempting many components of children’s products from testing. Yarn itself as a component is exempt from third party lead testing. Yarn is also exempt from phthalate testing.
However, an item that is made out of yarn may need some third party testing. If the yarn undergoes any kind of process that could introduce lead into it, it will need to be tested after that process. Also, many yarn-based items such as sweaters contain non-yarn components, such as buttons. If the buttons are not made of an exempt material such as wood or bone, they will need to be tested.
