Classification of boys' synthetic briefs under HS 6107.12
HS code 6107.12 covers men's or boys' underpants and briefs that are knitted or crocheted and made from man-made fibers. This includes synthetic fibers like polyester and polyamide (nylon), as well as artificial fibers like viscose, modal, or acetate. The classification is based on three main criteria: the function (undergarment), the construction (knitted), and the material (man-made). Knitted undergarments are preferred for their comfort, breathability, and elasticity. This code includes various styles such as traditional briefs, boxer briefs, and trunks, provided they are intended to be worn next to the skin as undergarments. The use of man-made fibers often implies moisture-wicking properties or high durability compared to natural fibers. It is essential to distinguish these from garments made of cotton or those that are woven, as these factors change the four-digit or six-digit heading. The garments must be identifiable as undergarments by their cut and fabric weight.

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).
