Goods which could be classified in two or more headings of this chapter are to be classified in the heading which occurs last in numerical order among those which equally merit consideration.

1. (A) Products (other than radioactive ores) answering to a description in heading 2844 or 2845 are to be classified in those headings and in no other heading of the Nomenclature. (B) Subject to paragraph (A) above, products answering to a description in heading 2843, 2846 or 2852 are to be classified in those headings and in no other heading of this Section. 2.

Goods put up in sets consisting of two or more separate constituents, some or all of which fall in this Section and are intended to be mixed together to obtain a product of Section VI or VII, are to be classified in the heading appropriate to that product, provided that the constituents are: (a) having regard to the manner in which they are put up, clearly identifiable as being intended for use together without first being repacked; (b) presented together; and (c) identifiable, whether by their nature or by the relative proportions in which they are present, as being complementary one to another.
