SECTION VI PRODUCTS OF THE CHEMICAL OR ALLIED INDUSTRIES VI-1 Notes 1. (a) Goods (other than radioactive ores) answering to a description in heading 2844 or 2845 are to be classified in those headings and in no other heading of the tariff schedule. (b) Subject to paragraph (a) above, goods answering to a description in heading 2843, 2846 or 2852 are to be classified in those headings and in no other heading of this section. 2.

For the purposes of the tariff 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 purposes 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
