Import Tips

Provide cocoon origin certificates to confirm noil-free silk, avoiding disputes with waste yarn categories

Label shipments clearly as 'industrial bulk yarn' to distinguish from retail under subheading definitions

Watch for bleaching agents; even fugitive dyes disqualify under unbleached yarn note (a)
