Hi @wambacher, Welcome to subforum of México.
[sorry, I know little english; I used google translator]
A few minutes ago, I sent email to the list Talk-MX[1][2], and I gave notice of your post here in the forum.
In Talk-MX I read something on imports, so hopefully soon get in touch with you here in the forum.
Thank you for coming to this forum to present your concerns.
Greetings from Mexico.
