CreativelyJeweled,
If the jewelry is made expressly for or sized to better fit the children in the wedding party then the CPSIA does apply, if it is identical in size and form to the adults' pieces then it's considered a general use item since more adults are using nearly identical pieces. If made the same size as the other wedding attendant pieces it then becomes brides choice to give it to the flower girls. So if you change the piece to fit down to a child or in this case where the bride order the pieces directly for the children you will need CPSIA testing info either for all the components used or on the finished products, tracking labels, small parts testing or warnings, and if you or the bride live in IL or CA the those state's approved lead testing reports and warning labels would be needed as well (the state level lead warnings would apply to the whole order not just the flower girls' pieces).
For non-exempt components like glass, crystal, & jewelry wire, you need a testing report from a CPSIA pre-approved lab stating
* a detailed description of the supply or component
* name of the lab that did the testing & contact info at the lab for the person or team that preformed the testing
* dates the testing was done
* which of the 2 approved test methodologies were used to determine the levels for each sustance that needs reporting
After you gather all the needed info you need to self issue for each product or set of nearly identical looking products a GCC that follows the CPSIA guidelines and keep that GCC on file at your place of bussiness that ties the testing reports to the tracking label.
So if you and the customer agree that the law must be followed, but don't have the time to wait for testing to be done, a flower girls' jewelry could always be made out of materials that are tested prior to assembly or from 100% exempt components. Getting the testing information from most jewelry component suppliers in the right format is nearly impossible since most are taking the position that the supplies they sell are and never where intended to used by or on jewelry for children under 14 (which is the Eropean Unions age cut off for their children product laws). There are raw materials that are on the lead testing exempt list, for the CPSIA, that you can use instead of glass or crystals
http://www.cpsc.gov/businfo/frnotices/fr09/leaddeterminationsfinalrule-draft.pdf . Keep in mind that the exempt materials are bridge to fine jewelry quality metals and stones so the flower girl's piece(s) could cost as much as the rest of the bridal jewelry order if the rest of the attendants pieces are of costume quality. Remember even using lead testing exempt materials you would still need the tracking label and the small parts (&/or state mandated) warning labels to be put on the packaging for the jewelry & tied to a self-issued GCC that you keep on file for the piece(s).
