The 3 exceptions that jump out at me are:
My understanding is that CITES is just about international trade - not the legality of your animals (although that may effect how kindly a Management Authority views your application for a licence - I don't know). If you want to export CITES controlled animals it's irrelevant whether USFW, or anyone else has issued paperwork. If your country is signed up to CITES you'll need a CITES licence. If you don't plan on shipping kaiseri out of the US you needn't worry about CITES.
2. Where a Management Authority of the State of export or re-export is satisfied that a specimen was acquired before the provisions of the present Convention applied to that specimen, the provisions of Articles III, IV and V shall not apply to that specimen where the Management Authority issues a certificate to that effect.
4. Specimens of an animal species included in Appendix I bred in captivity for commercial purposes, or of a plant species included in Appendix I artificially propagated for commercial purposes, shall be deemed to be specimens of species included in Appendix II.
Further definition of pre-convention regs can be found here: Resolution Conf. 13.65. Where a Management Authority of the State of export is satisfied that any specimen of an animal species was bred in captivity or any specimen of a plant species was artificially propagated, or is a part of such an animal or plant or was derived therefrom, a certificate by that Management Authority to that effect shall be accepted in lieu of any of the permits or certificates required under the provisions of Article III, IV or V.
Maybe it's an oversimplification on my behalf. If USFW issues import paperwork for c.b. animals to be imported I consider them to be legal to have.
