(b) Chemical substances and significant new uses subject to reporting.

(1) The chemical substances identified below, where 5 < n < 21 or 6 < m < 21, are subject to reporting under this section for the significant new uses described in paragraph (b)(2) of this section.

(i) CF3(CF2)n-COO-M where M = H − or any other group where a formal dissociation can be made;

(ii) CF3(CF2)n-CH = CH2;

(iii) CF3(CF2)n-C( = O)-X where X is any chemical moiety;

(iv) CF3(CF2)m-CH2-X where X is any chemical moiety; and

(v) CF3(CF2)m-Y-X where Y = non-S, non-N heteroatom and where X is any chemical moiety.

(2) The significant new use for chemical substances identified in paragraph (b)(1) of this section are: Manufacture (including import) or processing for use as part of carpets or to treat carpets (e.g., for use in the carpet aftercare market), except as noted in paragraph (b)(3) of this section.

(3) Manufacture (including import) or processing of the following two long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances for use as a surfactant in aftermarket carpet cleaning products shall not be considered a significant new use subject to reporting under this section:

(i) Phosphonic acid, perfluoro-C6-12-alkyl derivs. (CAS No. 68412-68-0) and

(ii) Phosphinic acid, bis(perfluoro-C6-C12-alkyl) derivs. (CAS No. 68412-69-1).

(c) Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph (c).

(1) Revocation of certain notification exemptions. With respect to imports of carpets, the provisions of §721.45(f) do not apply to this section. A person who imports a chemical substance identified in this section as part of a carpet is not exempt from submitting a significant new use notice. The other provision of §721.45(f), respecting processing a chemical substance as part of an article, remains applicable.

(2) [Reserved]
