Polypropylene Staple Fibers for Spinning from Japan

Carded polypropylene staple fibers processed specifically for spinning into yarns, typically 1.5 to 6 denier with lengths of 38-76 mm. These fibers fall under HTS 5506.40.00.00 as synthetic staple fibers of polypropylene that have been carded or otherwise processed for spinning. They are a key raw material in textile manufacturing for producing nonwoven fabrics and ropes.

Import Tips

Verify fiber composition via lab testing to confirm 100% polypropylene content, as blends may shift classification

Include processing certificates (e.g

carding reports) in documentation to prove 'processed for spinning' status

Avoid misdeclaration as unprocessed tow (5503.20), which has different duties; check staple length and denier specs
