Pterocarpus erinaceus

This wood species was recently (Jan. 2, 2017) added to CITES appendix II. With no CITES annotation on the listing, in addition to the raw wood, this restriction also extends to finished products made of Kosso wood.

Appearance-wise, it bears a strong resemblance to Muninga, another Pterocarpus species.

It is considered one of the “hongmu” (rosewood) species by the Chinese.

I have a sample of Kosso in the current queue, but it has yet to be processed. In the meantime, please see PROTA’s page for more information on this species.

I build guitars and want to use it for fret boards but I can not kind and information on its… Read more »
