There has been a lot of this going around- my friend John Thomas, Professor of Law at Quinnipiac university had written a brief commentary on it for fretboard journal:

The new ruling effectively helps instrument owners:
"Since publication of our regulations in 2007, we have given further consideration to the allowed use of a specimen within the United States when the listing status of the species changes after a specimen has been imported. We are amending this section to clarify that the allowed use after import into the United States is determined by the status of the specimen under CITES and the ESA at the time it is imported, except for a CITES specimen that was imported before the species was listed in Appendix I, or listed in Appendix II with an annotation disallowing commercial use, or listed in Appendix II or III and threatened under the ESA. Where an individual can clearly demonstrate that his or her specimen was imported with no restrictions on its use after import, prior to the species being listed under CITES with restrictions on its use after import, we will continue to allow use of the specimens as allowed at the time of import."
