HS code for Men's synthetic briefs: 6107.12
Underpants and briefs, men's or boys', of man-made fibres, knitted or crocheted.
Classification of men's synthetic briefs under HS 6107.12
Men's or boys' underpants and briefs made of man-made fibers and constructed via knitting or crocheting are classified under HS code 6107.12. This classification is based on the garment's function as an undergarment and its material composition. Man-made fibers include synthetic fibers like polyester and nylon, as well as artificial fibers like rayon or viscose. Chapter 61 of the Harmonized System specifically addresses knitted or crocheted apparel. The distinction between underpants (which cover the lower torso and legs) and briefs (which are legless) is irrelevant for this specific code, as both are included. The primary factor is the knit construction, which provides the necessary elasticity for undergarments, and the use of man-made fibers rather than natural fibers like cotton. These items are designed to be worn next to the skin and are categorized separately from nightwear or t-shirts, even if the materials are similar.

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).
