About heading 5503
Synthetic staple fibers, not carded, combed or otherwise processed for spinning
Heading 5503 covers synthetic staple fibers that are not carded, combed or otherwise processed for spinning. It is split by material: nylon or other polyamides, polyesters, acrylic or modacrylic, polypropylene, vinyon, and other. The nylon lines split by aramid status and nylon 12 content, and the polyester lines split by bicomponent bonding fiber type and by decitex.
