54.01 - Sewing thread of man-made fdaments, whether or not put up for retail sale. 540 1.10 - Of synthetic filaments 5401.20 - Of artificial filaments This heading covers sewing thread of man-made filaments in the forms and subject to the conditions described in Part (I) (B) (4) of the General Explanatory Note to Section XI. However, if such thread is within the definition of twine, etc. (see Part (I) (B) (2) of the General Explanatory Note to Section XI) it is excluded (heading 56.07). Sewing thread remains in this heading whether or not put u for retail sale or processed as indicated in Part (I) (El) (1) of the General Explanatory Note to ection XI.

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.
