Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the yarn is of viscose rayon, not cuprammonium
Cuprammonium rayon is a distinct artificial fibre; viscose rayon has its own subheading.
If the yarn is multiple (folded) or cabled
Multiple or cabled yarns are classified separately from single yarns.
If the yarn is of other artificial fibres, such as acetate
Other artificial filament yarns not elsewhere specified fall under this residual subheading.

Import Tips & Compliance
• Verify the twist is under 5 turns per metre to confirm it is low-twist, as higher twist yarns may be classified elsewhere
• Provide the decitex measurement to show it is under 67 decitex, which is the threshold for monofilament classification
• Ensure the yarn is not put up for retail sale, as retail packages change the tariff classification
