Sorry, but whether you intend your dolls for children or not, if they appeal to children, or are likely to be purchased for children, the CPSIA might decide you need to comply with this law.
And yes, unless the CPSC approves of component testing, as of Feb. 2010, all buttons, zippers, snaps, etc will need to be tested.
Tracking labels have been required since August, I make my own because I don't sew fast enough, or list in such quantity that I can order labels in bulk. The date of manufacture would expire on a bulk lot of labels before I got 'em sewn in to my items.
