> The law is not about what wasn't originally sold in the USA. Instead, it's specifically defines "grey market" imports and the whole purpose of the following text is for resellers to disclose the product's grey market status to inform the buyer.
That's what I'm trying to say. This law only applies when there are distributors or other parties that were sold the product outside the US and import it into the US.
> Read the actual text excerpt: "1797.81 (a)(1) The item is not covered by a manufacturer’s express written warranty valid in the United States "
That text excerpt says that if a product meets that criteria, it must have a label stating so. It doesn't say when that happens. "Every retail seller who offers grey market goods for sale shall post a conspicuous sign at the product’s point of display and affix to the product or its package a conspicuous ticket, label, or tag disclosing any or all of the following, whichever is applicable"
> You're inadvertently trying to say something else here but it's missing a word. I will correct your statement to be: "If it ever had a [VALID] US warranty, that warranty will not be invalidated by any selling or reselling."
Okay, I guess? I would say that an "invalid warranty" is not in fact a warranty, so the use of the word "valid" is redundant. But pretend I said "valid" if you want.
> The "grey market" products such as cameras/pianos/watches through side channels never had a valid US warranty in the first place.
But the "grey market" that we're talking about with AMD processors is largely composed of products that were sold in the US, with a valid US warranty, that are now being sold off later. You're using a much narrower definition that doesn't fit this entire conversation.
