Hi, I was digging around a little bit because of the laws surrounding woods. It’s probably a little bit of old news, but the last forum posts I could find where made before this specific change in the Cites regulations.
Now, I know Rosewood was under Appendix II which prohibited trade without certificates for quite a while. According to this article and multiple other sources https://www.gearnews.com/cites-rules-end-for-rosewood-in-musical-instruments-official-end-date-announced/
this regulation ended in November 2019, as the market for instruments was seen as very minimal compared to furniture. Maybe someone with more knowledge about this topic can confirm this as well?
I was also looking for some information considering Kouki. And altough the situation is somewhat unclear, and I found some documents specifically mentioning shamisen production, the ban on this wood seems to only affect logs, wood chips, powder and extracts. Finished products are specifically not banned.
So all in all all types of shamisen should at the moment technically be completely legal to export and import however you want, if I’m not mistaken?
