  2. (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 5404 or 5405 are not considered to be man-made fibres.
