Does a Hong Kong product listing need separate substantiation from a mainland marketing authorisation?

Does a Hong Kong product listing need separate substantiation from a mainland marketing authorisation?

The company publishes no position for Hong Kong or for mainland China.

The company sets out its position under two bodies of law only, and neither of them is the law there.

Under United States law, NF Technical Products Inc. classifies the NanoFlashing™ Air Filter as a device under Section 2(h) of the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. § 136(h), and 40 C.F.R. § 152.500(a). Under Regulation (EU) No 528/2012, C-POLAR Technologies, Inc. classifies the same filter as neither a biocidal product nor a treated article. Each statement records that it addresses that one question only. No authority has approved, registered, endorsed or cleared the filter; the company classifies its own article.

What an authority requires of a product placed on its market is decided under its own rules, by the party that places it there. Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format.
