     which fall in this section and are intended to be mixed together to obtain a product of
     section vi or vii, are to be classified in the heading appropriate to that product, provided
     that the constituents are:
     (a). Having regard to the manner in which they are put up, clearly identifiable as
          being intended to be used together without first being repacked;
     (b). Exported together; and
     (c). Identifiable, whether by their nature or by the relative proportions in which they
          are present, as being complementary one to another.
Additional U.S. Note
1.   For the purposes of the export schedule:
     (a). The term "aromatic" as applied to any chemical compound refers to such
          compound containing one or more fused or unfused benzene rings.
     (b). The term "modified aromatic" describes a molecular structure having at least one
          six-membered heterocyclic ring which contains at least four carbon atoms and
          having an arrangement of molecular bonds as in the benzene ring or in the
          quinone ring, but does not include any such molecular structure in which one or
          more pyrimidine rings are the only modified aromatic rings present.
     (c). For the purpose of headings 2902, 2907 and 3817, the term "alkyl" describes any
          saturated acyclic hydrocarbon group having six or more carbon atoms or, subject
          to note 1 to chapter 29, any mixtures of such groups averaging six or more
          carbon atoms.
