Subpart G.-Abrasives and Abrasive Articles Subpart G headnotes: 1. This subpart covers certain crude minerals commonly used for making abrasives and abrasive articles (items 519.01 through 519.17, inclusive) but these minerals are classifiable in this subpart even if they are not of abrasive quality. This subpart also covers certain minerals and artificial abrasives in forms suitable for use as abrasives or for abrasive purposes (items 519.31 through 519.37, inclusive). The remaining provisions of this subpart apply to papers, cloths, stones, and other articles which are cut or fashioned from natural stone or made from natural or artificial abrasive materials usually with the use of glues, resins, rubber or other binding materials, and which are designed and used for grinding, sharpening, smoothing, polishing, trueing, cutting, or similar purposes. The provisions of this subpart do not cover (1) sand (see subpart C of this part), unless made up into abrasive articles; (11) natural or synthetic diamond dust or powder (see subpart H of this part); (iii) crushed or powdered glass (see part 3 of this schedule), unless made up into abrasive articles; (iv) cosmetics and other toilet preparations (see part 7B of schedule 4); (v) soap and synthetic detergents (see part 8B of schedule 4); (vi) wheels or other abrasive articles mounted in frameworks or machines (see schedule 6); (vil) dental burrs (see part 2 of schedule 7); or (viii) tools to which abrasives have been applied but which have other functioning or working elements such as cutting teeth, edges, grooves, and fiutes (see schedule 6). 2.

PART 1.-NONMetallic MINERALS AND PRODUCTS, EXCEPT CERAMIC PRODUCTS AND Glass and GLASS PRODUCTS-Continued Part 2 headntoes: 1. This part covers ceramic wares, and articles of such wares and, in addition, certain unshaped refractory material (subpart A) closely related thereto. 2. For the purposes of the tariff schedules (a) a "ceramic article" is a shaped article having a glazed or unglazed body of crystalline or substantially crystalline structure, which body is composed essentially of inorganic nonmetallic substances and either is formed from a molten mass which solidifies on cooling, or is formed and subsequently hardened by such heat treatment that the body, if reheated to pyrometric cone 020, would not become more dense, harder, or less porous, but does not include any glass article; (b) the term "earthenware" embraces ceramic ware, whether or not glazed or decorated, having a fired body which contains clay as an essential ingredient and will absorb more than 3.0 percent of its weight of water; (c) the term "stoneware" embraces ceramic ware whether or not glazed or decorated, having a fired body which contains clay as an essential ingredient, is not commonly white, will absorb not more than 3.0 percent of its weight of water, and is naturally opaque (except in very thin pieces) even when fully vitrified; (d) the term "subporcelain" embraces fine-grained ceramic ware (other than stoneware), whether or not glazed or decorated, having a fired body which is white (unless artificially colored) and will absorb more than 0.5 percent but not more than 3.0 percent of its weight of water; (e) the terms "chinaware" and "porcelain" embrace fine-grained ceramic ware (other than stoneware), whether or not glazed or decorated, having a body which is white (unless artificially colored) and will not absorb more than 0.5 percent of its weight of water; (D) the term "bone chinaware" embraces chinaware or porcelain the body of which contains by weight 25 percent or more of calcined bone; (g) the term "nonbone chinaware" embraces chinaware or porcelain other than bone chinaware; (h) the term "coarse-grained", as applied to ceramic ware, embraces such wares having a body made of materials none of which had been washed, ground, or otherwise beneficiated: |
