beebles, Just to add to what Faye said already, your glaze must test at or below 90PPMs for lead plus certain other elements & compounds and there is no stay of testing on product that contain glazes, paints, inks (except CMYK which is exempt), pigments, tints, and dyes (except for food grade and fabric dyes which are exempt) so your test certificates must be done by a lab that is CPSIA cerified and to the CPSIA's standard of testing. Also ACMI and the ASTM does not use the same test methodology that the CPSIA requires which is total lead by weight, though they do test for lead absorbtion into the body that the EPA and FDA employ. Also with the glaze being the outer most layer of the product and blocks being considered a toy you will also need the test results on the 6 restricted phthalates with the levels being under 100PPM.
Also you need to know what process is use to make the original art work. If it's printed on non-glossy paper by your home ink jet printer it should be exempt, but if it's done in some other printing method you will need test results on the inks or paints used. You may need the durability testing mostly to see if the outer glaze would scrape off during normal play handling to see if this layer would be exposed and if it is then you may also need the phthalate infomation on what ever inks or paints used to make the art work.
As for the glue you may not need to have test results since the CPSC may deem that the glue itself is inaccessable. Unfortunately it's hard to judge what the CPSC will see as inaccessable since the agency itself seems unclear about what coatings and finishes, beyond a plasitic casing for electronics, makes something impossible to access. Best to try to contact the CPSIA themselves to get a case specific ruling.
As for the labeling of the box, you are correct, if the product is too small to contain an effective tracking label then the packaging must have all pertainant information for tracking purposes under the CPSIA. The labeling portion of the law went into effect on 8-14-09 there is no stay to this and all products that where made on or after that date must have the tracking label. As Faye said if the box or bag is going to be a permanant storage for the blocks than it too must meet all testing standards under the CPSIA.
As for the wood block itself if it is not treated in any way by you or by the mill that cut and is considered a natural piece of cut wood then it is on the exempt materials list. No test or certifications needed, but if anything is added to the wood, like say you purchased a length of 2x2 from a home improvement store to cut down in to your blocks and the h i store sells it as pest resistant wood then you need to know if chemicals were added to the wood to make it resistant or if it's a natural accruing trait of that type of wood. If chemicals where added then you need the test results.
As for the Feb date since you are using what the government considers a paint (the glaze) there is no stay of testing you need the test results for lead plus 12 (I think) other banned substance in paints, and possibly for the 6 phthalates since the item is a toy before you currently even list the item for sale as well as the tracking information on the box.
As said before WELCOME TO THE INSANITY!
