38.20 Anti-freezing preparations and prepared de-icing fluids. This heading covers anti-freezing preparations and prepared de-icing fluids (e.g., mixtures with a basis of glycol derivatives). Some anti-freezing preparations also act as coolants or as heat-exchange agents. It does not cover, however, repared additives for mineral oils or for other liquids used for the same purposes as mineral oils (heact'ing 38.11).

(B) With the exception of the products of Chapter 28 or 29, for the classification of certified reference materials, heading 38.22 shall take precedence over any other heading in the Nomenclature. 3.- Heading 38.24 includes the following goods which are not to be classified in any other heading of the Nomenclature : (a) Cultured crystals (other than optical elements) weighing not less than 2.5 g each, of magnesium oxide or of the halides of the alkali or alkaline-earth metals; (b) Fusel oil; Dippel's oil; (c) Ink removers put up in packings for retail sale; (d) Stencil correctors, other correcting fluids and correction tapes (other than those of heading 96.12), put up in packings for retail sale; and (e) Ceramic firing testers, fusible (for example, Seger cones). 4.- Throughout the Nomenclature, “municipal waste” means waste of a kind collected from households, hotels, restaurants, hospitals, shops, offices, etc., road and pavement sweepings, as well as construction and demolition waste.
