HS code for Singlet: 6109.90
T-shirts, singlets and other vests, of textile materials (other than cotton), knitted or crocheted.
Classification of singlet under HS 6109.90
Singlets and other vests are classified under HS code 6109.90 when they are knitted or crocheted and made from textile materials other than cotton. Heading 6109 specifically covers T-shirts, singlets, and other vests. The classification logic follows a hierarchy based on construction method and fiber content. First, the garment must be knitted or crocheted to fall within Chapter 61; woven singlets are classified in Chapter 62. Second, the material composition determines the subheading. While cotton garments fall under 6109.10, garments made from synthetic fibers (like polyester or nylon), artificial fibers (like viscose), or natural fibers (like wool or silk) are grouped under 6109.90. Singlets are defined as lightweight, sleeveless garments designed to be worn next to the skin, either as underwear or as outerwear. The absence of sleeves and the specific knitted texture are the primary physical characteristics used by customs authorities to differentiate these from other tops or shirts.

Codes often confused with 6109.90
Common mistake. The most common error is using 6109.10, which is only for cotton garments. Given the prevalence of cotton-poly blends, the 'rule of last beginning' or 'predominant weight' rule must be applied. Another misclassification occurs with 6207.11 or 6207.91, which are for woven singlets. If the garment has a collar or buttons, it might be reclassified as a shirt under 6105 or 6106.

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).
