Except where their context or note 4 to this chapter otherwise requires, the headings of this chapter cover only products which are in the crude state or which have been washed (even with chemical substances eliminating the impurities without changing the structure of the product), crushed, ground, powdered, levigated, sifted, screened, concentrated by flotation, magnetic separation or other mechanical or physical processes (except crystallization), but not products which have been roasted, calcined, obtained by mixing or subjected to processing beyond that mentioned in each heading. The products of this chapter may contain an added antidusting agent, provided that such addition does not render the product particularly suitable for a specific use rather than for general use. 2. This chapter does not cover: (a). Sublimed sulfur, precipitated sulfur or colloidal sulfur (heading 2802); (b). Earth colors containing 70 percent or more by weight of combined iron evaluated as Fe2O3 (heading 2821); (c). Medicaments or other products of chapter 30; (d). Perfumery, cosmetic or toilet preparations (chapter 33); (e). Setts, curbstones or flagstones (heading 6801); mosaic cubes and the like (heading 6802); roofing, facing or damp course slates (heading 6803); (f). Precious or semiprecious stones (heading 7102 or 7103); (g). Cultured crystals (other than optical elements) weighing not less than 2.5 g (0.088 ounces) each, of sodium chloride or of magnesium oxide, of heading 3824; optical elements of sodium chloride or of magnesium oxide (heading 9001); (h). Billiard chalks (heading 9504); or (i). Writing or drawing chalks or tailors' chalks (heading 9609). (j). See (i) above. 3. Any products classifiable in heading 2517 and any other heading of the chapter are to be classified in heading 2517. 4.
