SOT: duty on goods to be used for sale/business, bringing lenses back into the US Options

[TonyAKAVW]

So my wife is in Argentina now visiting her parents. She's leaving tomorrow evening and will be bringing back with her the first batch of the crystal-clear front turn signal lenses that my father-in-law has made. (See, the Neo914-6 thread) I told her bring back as many as she can, but she's wondering what the customs situation will be like and what she should be expecting to pay.

In looking at the U.S. Custom's web site, they specify that items for personal use are subject to an $800 exemption. Then they give the rates for other items above and beyond that. What they don't make clear though is for non-personal items, things for sale/business, what the rates are for the duty. Does anyone know? Is there a special form she should have with her before arriving?

And the idea of saying they are for personal use isn't going to work... 100 plastic lenses are clearly not for personal use (IMG:style_emoticons/default/smile.gif)
