Subheading Explanatory Note. Subheadings 2922 11 to 2922 50 For the purposes of classification in these subheadings, an ether function or an ester function of an organic or inorganic acid is regarded as an alcohol, phenol or acid function, depending on the position of the oxygen function in relation to the amino group. In these cases, only those oxygen functions which are present in the part of the molecule situated between the amine function and the oxygen atom belonging to the ether or ester function are to be taken into account. The segment containing the amine function is regarded as the "parent" segment. For example, in the compound 3-(2-aminoethoxy)propionic acid the parent segment is aminoethanol, and the carboxyl group is disregarded for classification purposes; this compound falls in subheading 2922 19 as an ether of an amino-alcohol. If a compound contains two or more ether or ester functions, the molecule is divided, for classification purposes, into parts at the oxygen atom of each ether or ester function, and only those oxygen functions which are in the same segment as the amine function are taken into account. If a compound has two or more amine functions linked to an ether or ester function, it falls in the subheading which is the last in numerical order of codes; the particular subheading

69 is determined taking into account whether a simple etheric or complex etheric functional group is considered as an alcohol i, phenolic or acidic functional group with respect to each amine functional group.
