Import Tips

Confirm stitch density meets Chapter 61 standards; low stitches (<10 per cm) may reclassify away from 6109

Include country-of-origin certificates for wool; superfine merino often imports from Australia/New Zealand

Avoid pockets below waist or ribbed bottoms to stay in 6109; document design specs for CBP review
