Bico Polyester Thermal Bonding Staple Fiber 4D 6mm from Mexico

Bi-component polyester staple fibers with a low-melt copolymer sheath surrounding a high-melt core, cut to 6mm length at 4 denier. Designed specifically for thermal bonding applications where the sheath melts at lower temperatures to fuse fibers without adhesives. Classified under HTS 5503.20.0015 due to their bi-component structure optimized for nonwoven bonding processes.

Import Tips

• Verify bi-component structure via manufacturer specs showing distinct sheath/core melt points to confirm HTS 5503.20.0015 classification

• Include technical datasheets documenting lower sheath melt temperature (typically 110-130°C vs core >150°C) in import documentation

• Avoid misclassification as standard polyester staple by highlighting thermal bonding end-use; common pitfall is grouping with 5503.20.0020
