HEADING 68.15 - ARTICLES OF STONE OR OF OTHER MINERAL SUBSTANCES (INCLUDING CARBON FIBRES ARTICLES OF CARBON FIBRES AND ARTICLES OF PEAT) NOT ELSEWHERE SPECIFIED OR INCLUDED.

71 COMMODITIES

6815.10 - Non-electrical articles of graphite or other carbon

6815.20 - Articles of peat

- Other articles :

6815.91 - - Containing magnesite dolomite or chromite

6815.99 - - Other

This heading covers articles of stone or of other mineral substances not covered by the earlier headings of this Chapter and not included elsewhere in the Nomenclature; it therefore excludes for example ceramic products of CHAPTER 69.

The heading covers inter alia :

(1) Non-electrical articles of natural or artificial graphite (including nuclear grade) or other carbons for example : filters; discs; bearings; tubes and sheaths; worked bricks and tiles; moulds for the manufacture of small articles of delicate design (e.g. coins medals lead soldiers for collections).

(2) Carbon fibres and articles of carbon fibres. Carbon fibres are commonly produced by carbonising organic polymers in filamentary forms. The products are used for example for reinforcement.

(3) Articles made of peat (for example sheets cylinder shells pots for raising plants). Textile articles of peat fibre are however excluded (Section XI).

(4) Unfired bricks made of dolomite agglomerated with tar.

(5) Bricks and other shapes (in particular magnesite or chrome-magnesite products) chemically bonded but not yet fired. These articles are fired during the first heating of the furnace in which they are installed. Similar products presented after firing are excluded (heading 69.02 or 69.03).

(6) Unfired silica or alumina vats (e.g. as used for melting glass).

(7) Touchstones for testing precious metal; these may be of natural stone (e.g. lydite a hard fine-grained dark stone resistant to acids).

(8) Paving blocks and slabs obtained by moulding fused slag without a binder but excluding those having the character of heat-insulating goods of heading 68.06.

(9) Filter tubes of finely crushed and agglomerated quartz or flint.

(10) Blocks slabs sheets and other articles of fused basalt; these are used because of their great resistance to wear as linings for pipes belt-conveyors chutes for coke coal ores gravel stone etc.

The heading also excludes :

(a)Blocks plates and similar semi-manufactures of artificial graphite or of " other carbon " mainly used for cutting  into electrical brushes (heading 38.01) (see corresponding Explanatory Note).

(b)Refractory goods fired as ceramics with a basis of carbonaceous substances (graphite coke etc.) and coal tar pitch or clay (heading 69.02 or 69.03 as the case may be).

(c)Carbons brushes electrodes and other parts or articles for electrical uses (heading 85.45).
