In my (albeit limited) experience, if you can’t get some sort of provenance documentation for exotic hardwoods from the lumberyard, it’s almost guaranteed to be unsustainably harvested, mostly outright illegally. Unfortunately it seems that most lumberyards open to the public and contractors are full of such wood because the legit stuff is even more expensive and sold mostly to high end furniture manufacturers and specialty suppliers.

Brazil is going to go through the same process as Cuba did with mahogany until trade in ipê is banned entirely, except it’s not an island so it’ll be impossible to enforce.
