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”.

      Headings 54.02 and 54.03 do not apply to synthetic or artificial
