The classification turns on the fabric construction of the outer shell. If the fabric forming the garment's outer surface is knitted or crocheted — meaning the loops interlock — it falls in chapter 61. Woven fabrics, where yarns interlace at right angles, go in chapter 62. Note 1 to Section XI and the chapter notes provide the controlling definitions; when construction is ambiguous, a textile lab analysis may be needed.

Yes. Many tariff lines in chapter 61 sourced from China are subject to Section 301 measures. The measure applies at the specific 10-digit HTS line level, so importers should verify each line's status against the current USTR annexes rather than assuming chapter-wide coverage.

Garments cover articles worn to clothe the body (shirts, trousers, dresses, etc.) and are classified under headings 6101–6114 by gender, garment type, and fiber. Accessories such as hosiery (6115), gloves (6116), and other made-up accessories (6117) are classified separately. The chapter notes and the Explanatory Notes to the HS clarify borderline articles such as leg warmers or wrist warmers.
