As copied from the US/Canadian Strategic Banjo Limitation Treaty (Sec.V, part 2, subpart b, paragraph 54a):

"...Before any Party can issue a permit to allow export of Banjos listed in Appendix I or II, the Scientific Authority of the State must advise that the proposed export will not be detrimental to the survival of the local music scene (the so-called non-detriment finding in Article III, paragraph 2(a), and Article IV, paragraph 2(a), of the Convention). The setting of an export quota by a Party in effect meets this requirement by establishing the maximum number of specimens of a Banjo that it will allow over the course of a year that will not have a detrimental effect on the survival of good music. The responsibility for establishing quotas thus lies with each individual Party (unless they have been set by the Conference of the Parties)..."

I hope this clears a few things up.
