Alternative Classifications

If featuring significant embroidery or lace
Garments prima facie classifiable in 6113 (knitted apparel with embroidery) prioritize that heading over 6107.
If for woven, not knitted versions
Non-knitted silk underpants move to Chapter 62 woven men's undergarments.

Import Tips & Compliance
