68.11 - Articles of asbestos-cement, of cellulose fibre-cement or the like.
This heading covers hardened articles consisting essentially of an intimate mixture of fibres (for example, asbestos, cellulose or other vegetable fibres, synthetic polymer, glass or metallic fibres) and cement or other hydraulic binders, the fibres acting as strengthening agents. These articles may also contain asphalt, tar, etc.
These products are generally manufactured by pressing together thin layers of a mixture of fibres, cement and water or by moulding (possibly under pressure), by pressing or by extruding.
The heading includes sheets of all sizes and thicknesses, obtained as described above, and also articles made by cutting these sheets or by pressing, moulding or bending them before they have set, e.g., roofing, facing or partition sheets and tiles; sheets for making furniture; window sills; sign-plates, letters and numbers; barrier bars; corrugated sheets; reservoirs, troughs, basins, sinks; tubing joints; packing washers and joints; panels imitating carving; ridge tiles, gutters, window frames; flower-pots; ventilation or other tubing, cable conduits; chimney cowls, etc.
All these articles may be coloured in the mass, varnished, printed, enamelled, decorated, drilled, filed, planed, smoothed, polished or otherwise worked; they may also be reinforced with metal, etc.
