54.04 - Synthetic monofilament of 67 decitex or more and of which no cross-sectional dunension exceeds 1 mm; strip and the Like (for example, artificial straw) of synthetic textile materials of an apparent width not exceeding 5 mm. - Monofilament : 5404.11 - - Elastomeric 5404.12 - - Other, of polypropylene 5404.19 - - Other 5404.90 - Other This heading covers : (1) S ~ t h e t i cmonofdament. These are filaments extruded as single filaments. They are c assified here only if they measure 67 decitex or more and do not exceed 1 mm in any cross-sectional dimension. Monofilaments of this h e d n g may be of any cross-secbonal configuration and may be obtained not ody by extrusion but by lamination or fusion. (2) Spi and the like, of synthetic textile materials. The strips of this heading are flat, of a widt not exceeding 5 rnrn,either produced as such by extrusion or cut from wider strips or from sheets. R Provided their apparent width (i.e., in the folded, flattened, compressed or twisted state) does not exceed 5 mm, this heading also covers : (i) Strip folded along the length. (ii) Flattened tubes, whether or not folded along the length. (iii)Strip, and articles referred to in (i) and (ii) above, compressed or twisted. If the width (or width) is not uniform, classification is to be decided by reference This heading also includes multiple (folded) or cabled strip and the like. All these products are generally in long lengths, but remain classified here even if cut into short lengths and whether or not ut up for retail sale. They are used according to their different characteristics in the man acture of brushes, sports rackets, fishing lines, surgical sutures, upholstery fabrics, belts, millinery, braids, etc. The heading does not include : (a) Sterile synthetic monofilament (heading 30.06). (b) Synthetic monofilament of which any cross-sectional dimension exceeds 1 mm, or strip and flattened tubes including strip and flattened tubes folded along the length), whether or not compressed or twiste (for example, artificial straw), provided that the apparent width (i.e., in the folded, flattened, compressed or turlsted state) exceeds 5 mrn (Chapter 39). (c) Synthetic monofilament measuring less than 67 decitex of heading 54.02. (d) Strip and the like of Chapter 56. (e) Synthetic monofilament, with hooks attached or otherwise made up into fishing lines (heading 95.07). (f) Prepared hots and tufts for brush-making (heading 96.03).
1.- Throughout the Nomenclature, the term “man-made fibres” means staple fibres and filaments of organic polymers produced by manufacturing processes, either : (a) By polymerisation of organic monomers to produce polymers such as polyamides, polyesters, polyolefins or polyurethanes, or by chemical modification of polymers produced by this process (for example, poly(vinyl alcohol) prepared by the hydrolysis of poly(vinyl acetate)); or (b) By dissolution or chemical treatment of natural organic polymers (for example, cellulose) to produce polymers such as cuprammonium rayon (cupro) or viscose rayon, or by chemical modification of natural organic polymers (for example, cellulose, casein and other proteins, or alginic acid), to produce polymers such as cellulose acetate or alginates. The terms “synthetic” and “artificial”, used in relation to fibres, mean : synthetic : fibres as defined at (a); artificial : fibres as defined at (b). Strip and the like of heading 54.04 or 54.05 are not considered to be man-made fibres. The terms “man-made”, “synthetic” and “artificial” shall have the same meanings when used in relation to “textile materials”. 2.- Headings 54.02 and 54.03 do not apply to synthetic or artificial filament tow of Chapter 55.
