These transmission or conveyor belts or belting are used for the transmission of power or the conveyance of goods. They are usually woven or plaited from yarns of wool, cotton, man-made fibres, etc. They are in various widths and may be in the form of two or more plies of such material woven or bonded together; sometimes they are woven with a short looped pile surface or with corded edges. They may be impregnated with linseed oil, Stockholm tar, etc., and may be coated with varnish, red lead, etc., to counter deterioration caused by atmospheric conditions, acid fumes, etc.
This heading also includes belts and belting made from woven synthetic fibres, in particular polyamides, coated, covered or laminated with plastics. They may also be reinforced with strips or threads of metal or of leather. In accordance with Chapter Note 6, belting of a thickness of less than 3 mm is excluded; this remains classified in Chapters 50 to 55, as narrow woven fabrics (heading 58.06), as braids (heading 58.08), etc. Transmission or conveyor belts (i.e., lengths of belting cut to size and either with the ends joined together or furnished with fastenings for joining them together) are classified here irrespective of the thickness of the material. This heading also covers transmission belts of textile rope or cord ready for use; these may be endless or with joined ends. The heading also excludes :(a) Transmission or conveyor belts or belting, presented with the machines or apparatus for which they are designed, whether or not actually mounted (classified with that machine or apparatus - e.g., Section XVI). (b) Belts or belting of textile fabric impregnated, coated, covered or laminated with rubber or made from textile yarn or cord impregnated, coated, covered or sheathed with rubber (heading 40.10, see Note 6 (b) to this Chapter).
