Section XI - Chapter 54
Manmade Filaments; Strip and the like of Manmade Textile Materials
Notes
1. Throughout the Schedule B, the term "manmade fibers" means staple fibers and filaments of organic polymers produced by manufacturing processes, either:
(a). By polymerization 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 of 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 fibers, mean: synthetic: fibers as defined at (a); artificial: fibers as defined at (b). Strip and the like of heading 5404 or 5405 are not considered to be manmade fibers.

The terms "manmade," "synthetic" and "artificial" shall have the same meanings when used in relation to "textile materials."

2. Headings 5402 and 5403 do not apply to synthetic or artificial filament tow of chapter 55.
Statistical Note
1. For the purposes of the woven fabrics of chapter 54, unless the context otherwise requires, provisions relating to one or more weaves embrace only those fabrics which (excluding selvage) are wholly of the specified weave or weaves, including combinations exclusively thereof.
