For the classification of tableware, kitchenware and other household articles of a decorative nature and particularly those incorporating decorative designs in relief and the like, see the HS Explanatory Note to heading 6913 , (B). 1. Beer mugs are generally classified in this heading; however, they are classified in heading 6913 if: 2. Articles which are in the shape of beer mugs, having decorative designs in relief or the like but with a capacity of less than 0,2 litre, generally fall in heading 6913 . Of common pottery These subheadings cover products obtained from ferruginous and calcareous clay (brick earth) which, when fractured, present an earthy, matt and coloured (generally, brown, red or yellow) appearance. Their fragment is heterogeneous; the diameter of the non-homogeneous element (particles, inclusions, pores) representative of the structure of the general mass should be greater than 0,15 mm. These elements are therefore visible to the naked eye. In addition, their porosity (coefficient of water absorption) is not less than 5 % by weight. Porosity is to be measured by the following method: Determination of the coefficient of water absorption Object and definition The object of the test is to determine the coefficient of water absorption of the ceramic material. This coefficient represents a percentage calculated in relation to the initial weight of the ceramic material. Preparation of test pieces and carrying out of tests There should be a minimum of three test pieces for each item to be tested. They should be taken from the enamelled parts of the same article and must not have more than one enamelled surface. The surface area of the test piece should be about 30 cm2 and its maximum thickness about 8 mm, including the enamel. Dry the test pieces in a kiln at 105 °C for 3 hours and, after cooling in a dryer, determine their weight (Wd) to the nearest 0,05 g. Then immediately immerse the test pieces in distilled water in such a way that they do not touch the bottom of the container. Boil in water for 2 hours, and then leave the test pieces in the water for 20 hours. Remove them and wipe off the surface water with a clean and slightly damp cloth. Dry any cavities and holes with a slightly damp thin brush. Ascertain the ‘wet’ weight Ww. The coefficient of water absorption of the test pieces is obtained by multiplying the increase in weight by 100 and dividing by the dry weight: Evaluation of results The average of the coefficients of water absorption of the different test pieces, expressed as a percentage, is the water absorption coefficient of the ceramic material. 6912 00 23 and 6912 00 83 Stoneware These subheadings include products obtained from clay usually coloured in the mass; they are characterised by a compact, opaque fragment which is kilned at a sufficiently high temperature for vitrification to occur. Translucency is to be determined on a fragment having a thickness of at least 3 mm by the following test: Translucency test Definition The outline of an object must be visible through a test piece between 2 and 4 mm thick placed in a dark room 50 cm from a new lamp enclosed in a box and emitting a beam of light of between 1 350 and 1 500 lumens. The lamp must be changed after 50 hours' use. Testing apparatus (see sketch below) The apparatus consists of a box painted internally in white mat finish. At one of the ends is placed the lamp (A). A hole is made at the opposite end so that the outline of the object (B) may be seen through the test piece (C). The dimensions of the box are as follows: The diameter of the hole is approximately 10 cm. In addition, their porosity (coefficient of water absorption) is 3 % or less by weight. Porosity is to be measured by the method set out in the explanatory note to subheading 6912 00 21 . 6912 00 25 and 6912 00 85 Earthenware or fine pottery These subheadings cover products made by firing a mixture of selected clays (‘fine pottery’), sometimes mixed with feldspar and with varying amounts of chalk (hard earthenware, mixed earthenware, soft earthenware). Earthenware products are characterized by a white or light-coloured fragment (slightly greyish, cream or ivory) and fine pottery products by a coloured fragment ranging from yellow to brown or reddish-brown. Their fragment, which has a fine grain, is homogeneous; the diameter of the non-homogeneous elements (particles, inclusions, pores) representative of the structure of the general mass should be less than 0,15 mm; these elements are therefore not visible to the naked eye. In addition, their porosity (coefficient of water absorption) is 5 % or more by weight. Porosity is to be measured by the method set out in the explanatory note to subheading 6912 00 21 . 6912 00 29 and 6912 00 89 Other These subheadings cover products which correspond neither to the criteria laid down for the products falling in the other subheadings of this heading nor to those applying to porcelain (heading 6911 ).
