Classification of synthetic knit pants under HS 6104.63

Synthetic knit pants for women or girls are classified under HS code 6104.63. This heading includes trousers, bib and brace overalls, breeches, and shorts. As part of Chapter 61, the classification requires the garment to be knitted or crocheted. The use of synthetic fibers, such as polyester, elastane (when blended), or acrylic, directs the classification to the .63 subheading. Trousers are defined as garments that cover each leg separately, reaching from the waist down to the ankles or lower. This code also covers leggings, provided they are not considered hosiery (which would fall under 6115). The classification process involves analyzing the fiber content by weight; if synthetic fibers are the most significant component by weight compared to other textile materials, 6104.63 is appropriate. It is important to distinguish these from woven trousers, which are classified in Chapter 62, even if they contain synthetic fibers. The construction of the waistband and the presence of pockets or zippers do not change the fundamental classification as long as the fabric is knitted.

Codes often confused with 6104.63

Common mistake. The most frequent misclassification is 6204.63, which is for woven synthetic trousers. Another common error involves 6115, which covers pantyhose and tights; the distinction depends on whether the garment is intended to be worn as an outer garment (6104) or as hosiery (6115). If the pants are made of cotton, they fall under 6104.62. Men's or boys' versions are classified under 6103.43.

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).
