What does each displayed federal identifier identify, and what does it fail to establish about performance or authorization?

An EPA establishment number identifies the place where an article was produced.

It identifies nothing else. 40 C.F.R. § 156.10(f) is the provision that puts it on a label: “The producing establishment registration number preceded by the phrase ‘EPA Est.,’ of the final establishment at which the product was produced may appear in any suitable location on the label or immediate container.” It is not a registration of the product, it is not an approval, and it carries no finding about how the article performs. No agency has approved, registered or cleared the NanoFlashing™ Air Filter. The company classifies the article itself.
