Chapter notes
- Except where the context otherwise requires, the headings of this Chapter apply only to: (a) Separate chemically defined organic compounds, whether or not containing impurities; (b) Mixtures of two or more isomers of the same organic compound (whether or not containing impurities), except mixtures of acyclic hydrocarbon isomers (other than stereoisomers), whether or not saturated (Chapter 27); (c) The products of headings 29.36 to 29.39 or the sugar ethers, sugar acetals and sugar esters and their salts (heading 29.40), or the products of heading 29.41, whether or not chemically defined; (d)-(h) products dissolved in water or other solvents, with added stabilisers, anti-dusting agents, colouring or odoriferous substances or emetics, and diazonium salts diluted to standard strengths.
- This Chapter does not cover: (a) Goods of heading 15.04 or crude glycerol (heading 15.20); (b) Ethyl alcohol (heading 22.07 or 22.08); (c) Methane or propane (heading 27.11); (d) The compounds of carbon mentioned in Note 2 to Chapter 28; (e) Immunological products of heading 30.02; (f) Urea (heading 31.02 or 31.05); (g) Colouring matter of vegetable or animal origin (heading 32.03), synthetic organic colouring matter (heading 32.04) or dyes put up for retail sale (heading 32.12); (h) Enzymes (heading 35.07); (i) Metaldehyde, hexamethylenetetramine in forms for use as fuels (heading 36.06); (k) Products put up as charges for fire-extinguishers (heading 38.13); ink removers put up for retail sale (heading 38.24); (l) Optical elements, for example ethylenediamine tartrate (heading 90.01).
- Goods which could be included in two or more of the headings of this Chapter are to be classified in that one of those headings which occurs last in numerical order.
- The esters of acid-function organic compounds of sub-Chapters I to VII with organic compounds of these sub-Chapters are to be classified with that compound which is classified in the heading which occurs last in numerical order in these sub-Chapters. Esters of ethyl alcohol with acid-function organic compounds of sub-Chapters I to VII are to be classified in the same heading as the corresponding acid-function compounds.
