Hi Mike,
There is a thread about the new law and the requirements for selling to kids 12 and under. Here is a link:
Confused by new CPSIA laws? I am! Do you sell anything to kids ages 12 and under?
It's a long thread. The most current discussion is happening on the last page, of course. But those guys and gals in there are keeping up closely on the developments.
I keep in touch with the thread, as I have sold, and since stopped, bc of this new law, youth. I haven't seen anything "per se" about tracking labels, but what you are describing sounds like it may have something to do with the testing certifications. If you go to that thread I linked you to, you will be in the right place to find out what the lastest and greatest is on all of this, and ask those folks what they know. They'll likely be able to help you figure out what all of that means. Best wishes.
