Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If multiple yarns plied together
Single yarn vs multiple yarn plied construction splits within 5402.11.30 subheading.
If further processed into industrial twine/rope
Chapter 56 covers plied/twisted constructions exceeding simple yarn definitions.
If acrylic filament rather than polyamide aramid
Acrylic high-tenacity yarns use separate 5402.52 provisions by polymer type.

Import Tips & Compliance
• Submit chemical analysis confirming para-aramid structure and high modulus (>900 g/den) for proper duty assessment
• Declare exact decitex and zero/low twist specs; over 920 dtex moves to higher statistical breakouts
• Avoid retail labeling/packaging to prevent reclassification under consumer yarn provisions
