- 1. In determining the amount of duty applicable to a solution of a single compound in water subject to duty in this section at a specific rate, an allowance in weight or volume, as the case may be, shall be made for the water in excess of any water of crystallization which may be present in the undissolved compound.
- 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 chapter 29, any mixtures of such groups averaging six or more carbon atoms.
