Section XIII - Chapter 69
Ceramic Products
Notes
1. This chapter applies only to ceramic products which have been fired after shaping. Headings 6904 to 6914 apply only to such products other than those classifiable in headings 6901 to 6903.
2. This chapter does not cover:
(a). Products of heading 2844;
(b). Articles of heading 6804;
(c). Articles of chapter 71 (for example, imitation jewelry);
(d). Cermets of heading 8113;
(e). Articles of chapter 82;
(f). Electrical insulators, (heading 8546) or fittings of insulating material (heading 8547);
(g). Artificial teeth (heading 9021);
(h). Articles of chapter 91 (for example, clocks and clock cases);
(ij). Articles of chapter 94 (for example, furniture, lamps and lighting fittings, prefabricated buildings);
(k). Articles of chapter 95 (for example, toys, games and sports equipment);
(l). Articles of heading 9606 (for example, buttons) or of heading 9614 (for example, smoking pipes); or
(m). Articles of chapter 97 (for example, works of art).
Statistical Notes
1. For the purposes of this chapter, a ceramic article is a shaped article having a glazed or unglazed body of crystalline or substantially crystalline structure, the body of which is composed essentially of inorganic nonmetallic substances and 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 articles.
2. For the purpose of headings 6902 and 6903, the term "refractory is applied to articles which have a pyrometric cone equivalent of at least 1500 degrees C when heated at 60 degrees C per hour (pyrometric cone 18). Refractory articles have special properties of strength and resistance to thermal shock and may also have, depending upon the particular uses for which designed, other special properties such as resistance to abrasion and corrosion.
3. For the purpose of heading 6902, a brick which contains both chromium and magnesium is classifiable according to which of those components (expressed as Cr2O3 or MgO, respectively) is the greater by weight.
4. For the purposes of headings 6905 and 6907, the term "tiles" does not include any article 3.2 cm (1.260 inch) or more in thickness.
5. For the purposes of headings 6909 through 6914:
(a). The terms "porcelain" and "china" embrace ceramic ware (other than stoneware), whether or not glazed or decorated, having a fired white body (unless artificially colored) which will not absorb more than 0.5 percent of its weight of water and is translucent in thickness of several millimeters. The term "stoneware" as used in this note, embraces ceramic ware which contains clay as an essential ingredient, is not commonly white, will absorb not more than 3 percent of its weight of water, and is naturally opaque (except in very thin pieces) even when absorption is less than 0.1 percent.
(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 percent of its weight of water.
(c). The water absorption of a ceramic body shall be determined by ASTM test method designated C373 (except that test specimens may have a minimum weight of 10 g, and may have one large surface glazed).
6. For the purposes of heading 6904:
(a). The term "solid bricks" refers to bricks containing not more than 25 percent voids.
(b). The term "hollow bricks" refers to bricks containing more than 25 percent voids.
