More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of acrylic or modacrylic
Different synthetic material (acrylic) changes the subheading within Chapter 54, as polyamides are specific to 5402.45.
If made from staple fibers, not filament
Filament yarn stays in 5402; if cut into staple and spun, it moves to Chapter 55 woven fabrics or yarns.
If woven into fabric
Once woven into greige fabric, classification shifts from yarn (5402) to woven synthetic fabric (5407).

Import Tips & Compliance
• Include tenacity and elongation specs in documentation to justify industrial use; misdeclaration as apparel yarn risks higher duties
• Avoid retail-like packaging (e.g
• small hanks)—use beams >10kg to stay in 5402; test for twist uniformity
