Notes.

 

1.‑ 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);

(e)                    The products mentioned in (a), (b) or (c) above dissolved in other solvents provided that the solution constitutes a normal and necessary method of putting up these products adopted solely for reasons of safety or for transport and that the solvent does not render the product particularly suitable for specific use rather than for general use;

(g)                    Enzymes (heading 35.07);

 

(h)                    Metaldehyde, hexamethylenetetramine or similar substances, put up in forms (for example, tablets, sticks or similar forms) for use as fuels, or livid or liquefied‑gas fuels in containers of a kind used for fillin or refilling cigarette or similar lighters and of a capacity not exceeding 300 cm (heading 36.06);

 

(ij) Products put up as charges for fire‑ext'&uishers or put up in fire‑extinguishing grenades, of heading 3 .13; ink removers put up in packmgs for retail sale, of heading 38.24; or

 

 (k) Optical elements, for example, of ethylenediamine tartrate (heading 90.01).

 

 

3.‑ 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' numerical order.

 

4.‑ In headings 29.04 to 29.06, 29.08 to 29.11 and 29.13 to 29.20, any reference to halogenated, sulphonated, nitrated or nitrosated derivatives includes a reference to compound derivatives, such as sulphohalogenated, nitrohalogenated, nitrosulphonated or nitrosulphohalogenated derivatives.

 

 

Nitro or nitroso groups are not to be taken as "nitrogen‑fimctions" for the purposes of heading 29.29.

 

For the purposes of headings 29.11, 29.12, 29.14, 29.18 and 29.22, "oxygen‑function" is to be restricted to the fimctions (the characteristic organic oxygen‑containing groups) referred to in headings 29.05 to 29.20.

 

 

5.‑ (a) 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.

 

(b) Esters of ethy1 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.

 

(c) Subject to Note 1 to Section VI and Note 2 to Chapter 28

 

(1)                    Inorganic salts of organic compounds such as acid‑, phenol‑ or enol‑fimction compounds or organic bases, of sub‑Chapters I to X or heading 9.42, are to be classified in the heading appropriate to the organic compound; and

 

(2)                    Salts formed between organic compounds of sub‑Chapters I to X or heading 29.42 are to be classified in the heading approphate to the base or to the acid (including phenol‑ or enol­function compounds) from which they are formed, whichever occurs last in numerical order in the Chapter.

 

 (d) Metal alcoholates are to be classified in the same heading as the corresponding alcohols except in the case of ethanol (heading 29.05).

 

(e) Halides of carboxylic acids are to be classified in the same heading as the corresponding acids.

 

6.‑ The compounds of headings 29.30 and 29.31 are organic compounds the molecules of which contain, in addition to atoms of hydrogen, oxygen or nitrogen, atoms of other non‑metals or of metals (such as sulphur, arsenic, mercury or lead) directly linked to carbon atoms.

 

 

   Heading 29.30 (or gano‑sulphur compounds) and heading 29.31 (other organo‑inorganic compounds) do not include sulphonated or halogenated derivatives (includrng compound derivatives) which, apart from hydrogen, oxygen and nitrogen, only have directly linked to carbon the atoms of sulphur or of a halogen which give them their nature of sulphonated or halogenated derivatives (or compound derivatives).

 

7.‑ Headings 29.32, 29.33 and 29.34 do not include epoxides with a three‑membered ring,. ketone peroxides cyclic po lymers of aldehydes or of thioaldehydes, anhydrydes of polybasic carboxylic acids, cyclic esters of polyhydric alcohols or phenols with polybasic acids, or imides of polybasic acids.

 

These provisions apply only when the ring‑position hetero‑atoms are those resulting solely from the cyclising function or, functions here listed.

 

8.‑ For the purposes of heading 29.37:

 

(a)                    the term "hormones" includes hormone‑releasin or hormone‑stimulating factors, hormone inhibitors and hormone antagonists (anti‑hormones);

 

(b)                    the expression "used primarily as hormones" applies not only to hormone derivatives and structural analogues used primarily for their hormonal effect, but also to those derivatives and structural analogues used primarily as intermediates in the synthesis of products of this heading.

 

Subheading Note.

 

1.‑ Within any one heading of this Chapter, derivatives of a chemical compound (or group of chemical compounds) are to be classified in the same subheading as that compound (or group of compounds) provided that they are not more specifically covered by any other subheading and that there is no residual subheading named "Other" in the series of subheadings concerned.
