Kevlar Aramid Staple Fibers
Short-cut Kevlar aramid staple fibers, not carded, combed, or processed for spinning, used primarily for reinforcement in composites and protective textiles. Classified under HTS 5503.11.00.00 as synthetic staple fibers of aramids in their raw, unprocessed form. These fibers leverage aramid's high strength-to-weight ratio for demanding applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If continuous filament yarns rather than staple
Aramid continuous filaments like Kevlar yarn classify under Chapter 54 as synthetic filament yarns, not staple fibers.
If carded, combed, or processed for spinning
Any processing beyond raw staple form moves to Chapter 55 headings for prepared aramid fibers.
If imported in bulk tow form exceeding 2 denier per filament
Aramid tows over 2 dpf are classified as plied synthetic tow, separate from fine staple fibers.

Import Tips & Compliance
• Verify aramid composition via supplier certificates to avoid reclassification; ensure fibers are unprocessed (no carding/combing) with lab tests if challenged; declare exact denier and length for accurate duty assessment
