Import Tips
• SxS morphology creates self-crimping; emphasize bonding function over crimp in classification rulings
• Interlining manufacturers common importers; require fiber opening/process trials documentation
• Color variations (white/dope-dyed) don't affect duty but note for inventory traceability
