This heading covers moulded pressed or centrifuged articles (e.g. certain pipes) of cement (including slag cement) of concrete or of artificial stone other than those of heading 68.06 or 68.08 (in which cement is merely a binder) or heading 68.11 (articles of asbestos-cement).

This heading also covers prefabricated structural components for building or civil engineering.

Artificial stone is an imitation of natural stone obtained by agglomerating pieces of natural stone or crushed or powdered natural stone (limestone marble granite porphyry serpentine etc.) with lime or cement or other binders (e.g. plastics). Articles of artificial stone include those of " terrazzo " granito etc.

This heading also covers articles of slag cement.

The heading includes inter alia blocks bricks tiles; ceiling or wall mesh or lath (consisting of a wire framework combined with a predominating proportion of concrete); flagstones; beams; hollow flooring slabs and other constructional goods; pillars posts boundary stones; curbstones; piping; stair treads; railings; baths sinks water closet pans (bowls) troughs vats reservoirs; fountain basins; tombstones; standards poles; railway sleepers; hovertrain guide-track sections; door or window frames; mantelpieces window sills door steps; friezes cornices; vases flower-pots architectural or garden ornaments; statues statuettes animal figures; ornamental goods.

The heading also covers bricks tiles and other sandlime articles made from a pasty mixture of sand lime and water; after pressure-moulding these articles are steam-treated for several hours under high pressure in horizontal autoclaves at a temperature of around 140 øC. These products which may be white or artificially coloured are used for much the same purposes as ordinary bricks tiles etc.

When lumps of quartz of various sizes are introduced into the mixture artificial stone type products are obtained. Lightweight and porous sand-lime sheets for insulating purposes are also made by adding a metallic powder to the mixture so that gases are given off; such sheets however are not pressure-moulded but cast before insertion in the autoclave.

The articles of this heading may be bushed ground polished varnished bronzed enamelled made to imitate slate moulded or otherwise ornamented coloured in the mass reinforced with metal etc. (e.g. reinforced or pre-stressed concrete) or fitted with accessories of other materials (e.g. hinges etc.).

The heading does not include articles made of agglomerated slate (heading 68.03).

Subheading Explanatory Note.

Subheading 6810.91

This subheading covers prefabricated structural components for building or for civil engineering such as facing panels interior walls floor or ceiling sections foundation components pilings tunnel sections components for lock-gates or dams gangways cornices. These components generally of concrete usually have devices for facilitating their assembly.
