Federal registry means a federal dataset — an FDA device or drug listing, a TTB permit, a federal award — records this product against the facility or its company. It is not an approval of anything by anyone. Company website means we read it from the company’s own site. Company-provided means the verified owner of a claimed page added it: a claimed page may add products, and every one it adds is marked that way here.
