Most of the items in Class 19 are materials, not of metal, for building and construction; building and construction materials made of metal are in Cl. 6. Building glass also belongs to Class 19 even though unworked or semi-worked glass is generally in Cl. 21.
Rigid pipes, not of metal, for building belong to Class 19. It should be noted that there are also pipes in Cl. 6, Cl. 11 and Cl. 17. Pipes are considered to be construction materials and are thus classified in Class 19 if they are rigid and non-metallic, and in Cl. 6 if they are made of metal (whether rigid or flexible). Flexible non-metallic pipes such as watering hoses or connecting hoses for vehicle radiators are in Cl. 17, and pipes that are directly attached to, and are specialized parts of, sanitary installations such as sinks, showers and toilets are in Cl. 11.
Also, some specialized building materials like asphalt, pitch, tar and bitumen are in Class 19 when they might otherwise be classified in another class. For example, bituminous coatings for roofing could be in Cl. 2 as a coating but are in fact classified in Class 19 because they are considered to be a specialized building product.
Anything that constitutes a structure and is not made primarily of metal, from bicycle parking installations to entire buildings, can also be classified in Class 19. This includes facilities such as swimming pools and skating rinks which are classified according to material composition, rather than by function. Complete homes that are built entirely in a factory and then transported and installed on-site are in Class 19 if they are composed primarily of non-metallic components, and in Cl. 6 if they are primarily made of metal. Class 19 also includes monuments, not of metal; those of metal are in Cl. 6.
Class 19 includes materials such as stone, concrete and marble. It also includes certain finished goods that are classified according to material composition. In the Nice Classification, finished goods are in principle classified according to function or purpose. Goods that cannot be classified in this way are classified according to other criteria, like the material of which they are made (see General Remark (a) for Goods). Busts, figurines and other similar goods made of stone, marble or other Class 19 materials are thus in Class 19 since there is no specific class in the Nice Classification for three-dimensional works of art.
