Even luthiers have to declare their existing wood stocks, even if they ve had them for dozens of years. But I do not agree with your point of view that it is "only wood". Exotic woods exploitation is killing the rain forests and specific tree species. With everybody nowadays wanting a rosewood neck on them guitars, the dimension of the problem is global and huge. Anyway now, those endangered species are being replanted. But only at a huge price you can get aquality rosewood. I live in a place where old buildings like churches and palaces contain 400 old rosewood in their decoration and furniture. (Built 400 years ago, and wood of a tree that was hipothetically 300 years old when he was cut down, is 700 hundred years old now). The quality of that rosewood is incredibly good. You just cant see the wood grain because it is so tight. And that dark brown coloration is sheer beauty. You cant know what is is before you see and touch it. You cant find that wood quality anywhere now. Everyone wants a piece of it in his instrument It is normal to control that by blocking international sales. Dura lex sed lex (law is though, but it is the law). Most of those woods have non endangered substitutes anyway, growing in northern hemisphere countries, for instruments and other purposes (furniture, floors, windows). Let s use those wood, and stop wanting the exotic woods, which is but a fashion that devastates forests and natural sites that are not ours and just make some dictators and generals richer, like in Indonesia, Africa, and all the other developping countries all over the world. People must be told they just cant have everything they want (so unamerican), but the world is not a candy store! Cheers.
