Classification of men's knit underwear under HS 6107.12
The classification of men's knit underwear made of man-made fibers under HS code 6107.12 is determined by the garment's material composition and its manufacturing method. Chapter 61 of the Harmonized System covers all apparel that is knitted or crocheted. Heading 6107 specifically includes men's or boys' underpants, briefs, and similar intimate apparel. Subheading 12 is designated for those items made from man-made fibers, which include synthetic fibers like polyester, nylon, and acrylic, as well as artificial fibers like rayon or viscose. In the modern apparel industry, man-made fibers are frequently used in underwear to provide moisture-wicking properties, durability, and stretch, often in the form of jersey or rib-knit fabrics. To be classified under this code, the garment must be primarily composed of these fibers by weight. The classification process follows the General Interpretative Rules, ensuring that the product is placed in the most specific category available. This code is distinct from those for cotton underwear or woven underwear. Proper identification is crucial for importers and exporters, as man-made fiber garments may be subject to different trade agreements, quotas, or anti-dumping duties compared to natural fiber products.

Codes often confused with 6107.12
Common mistake. HS code 6107.11 (cotton) is often used if the fiber blend is misunderstood; 6107.12 requires man-made fibers to predominate. 6207.12 would be for woven man-made fiber underwear, such as traditional woven boxers. 6109.90 (T-shirts of other materials) is sometimes confused with undershirts, but 6107 specifically covers the lower-body undergarments like briefs and underpants. Furthermore, if the item is intended for swimwear, it must be classified under 6112.31.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
