I make hand-knitted stuff, how does CPSIA affect me?
Yarn, both natural and synthetic, is on the CPSC’s list of materials exempt from both third party lead testing and phthalate testing. So any knitted or crocheted product that is made entirely of yarn does not require any third party testing.
However, if you add a button, zipper, or any other part not made of yarn, you will have to make sure it is compliant. If it’s made of an exempt material, such as plain wood, it does not have to be tested. If it is made of plastic or metal, has a surface coating (paint) or any other feature that makes it non-exempt, you will have to have third party laboratory testing done.
You will also need to comply with the new tracking label requirements. And if your product includes small parts that can be removed and choked on, you will need to comply with the small parts labeling requirements. A small parts warning must be both on the packaging and visible at the point of sale. If you only sell goods at stores or in person, you can label just the packaging. If you sell through a catalog, brochure, or over the internet, the small parts warning must be on your catalog, brochure, or webpage.
Based on the information here: http://www.cpsc.gov/BUSINFO/regsumsmallparts.pdf it seems like small parts on clothing are exempt from the Small Parts Regulation. Doesn’t that mean onesies or other pieces of with buttons are exempt from this rule?
