oops, nevermind, I found it online: www.eurococoa.com/cocoa/index.htm

Turns out it's the same thing.

I have no idea, Devi, I'm not sure what you're looking for. If you could explain? I don't think they have to disclose at all, but I don't work for the FDA.

In the original post, you seemed to be trying to avoid ingredients that weren't part of "good" or "pure" or "organic" chocolate; containing stuff that's cheap additive. OK so we cleared that up. But almost every chocolatier will "fool around with" their chocolate, it's how they make a unique product. Now as for how much of it they disclose, vs say "flavorings added" on the label, I do not know. If people are using rare or expensive or unique ingredients... if you used for instance organic estate-grown Réunion vanilla bean, you will damn sure advertise it. (and charge accordingly.) And there's really common adjuncts like soy lecithin (an emulsifier) that nearly every chocolate will have.

So what are you trying to avoid, exactly? Just poor quality ingredients in general? You didn't specify anything but "cheap" so stick to the upper end of chocolatiers and you'll do fine.
