bonds, other than metal‑carbon bonds.
 (D) Metal alcoholates are to be classified in the same heading as the corresponding alcohols except in the case of ethanol (2905).
 (E) Halides of carboxylic acids are to be classified in the same heading as the corresponding acids.
 6.‑ The compounds of 2930 and 2931 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 or lead) directly linked to carbon atoms.
2930 (organo‑sulphur compounds) and 2931 (other organo‑inorganic compounds) do not include sulphonated or halogenated derivatives (including 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.‑ 2932, 2933 and 2934 do not include epoxides with a three‑membered ring, ketone peroxides, cyclic polymers of aldehydes or of thioaldehydes, anhydrides 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 2937:
 (a) "hormones" includes hormone‑releasing or hormone‑stimulating factors, hormone inhibitors and hormone antagonists (anti‑hormones);
 (b) "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 Notes.
 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.
 2.‑ Note 3 to Chapter 29 does not apply to the subheadings of this Chapter.

Additional Note.
 1.‑ In 2920, "esters of inorganic acids" are to be taken to include carbonic and peroxocarbonic esters.
