55.03 - Synthetic staple fibres, not carded, combed or otherwise processed for spinning. - Of nylon or other polyamides : - - Of aramids 5503.19 - - Other 5503.20 - Of polyesters 5503.30 - Acrylic or modacrylic 5503.40 - Of polypropylene 5503.11 5503.90 - Other The fibres of this heading are manufactured as described in the General Explanatory Note to this Chapter. Synthetic staple fibres are usual1 press-packed in bales. The fibres are generally of uniform length, which distinguishes them om the waste material of heading 55.05. X The heading also covers synthetic filament tow of a length not exceeding 2 m provided that each filament measures less than 67 decitex. Synthetic filament tow of a length exceeding 2 rn is excluded (heading 54.02 or 55.01). Synthetic staple fibres which have been carded, combed or otherwise processed for spinning are also excluded (heading 55.06).
1.- Headings 55.01 and 55.02 apply only to man-made filament tow, consisting of parallel filaments of a uniform length equal to the length of the tow, meeting the following specifications : (a) Length of tow exceeding 2 m; (b) Twist less than 5 turns per metre; (c) Measuring per filament less than 67 decitex; (d) Synthetic filament tow only : the tow must be drawn, that is to say, be incapable of being stretched by more than 100 % of its length; (e) Total measurement of tow more than 20,000 decitex. Tow of a length not exceeding 2 m is to be classified in heading 55.03 or 55.04.
