Classification of women's cotton nightgown under HS 6108.31
The classification of women's cotton nightgowns under HS code 6108.31 is based on two primary factors: the garment's intended use as sleepwear and its knitted construction. Heading 6108 covers a range of women's intimate apparel and loungewear that is knitted or crocheted. Subheading 6108.31 specifically targets nightdresses and pyjamas made of cotton. For a product to be classified here, it must be clearly identifiable as a garment intended for sleeping. The "knitted" requirement means the fabric is formed by interlocking loops of yarn, which is common for cotton nightgowns due to the comfort and breathability of the resulting textile. If the garment features a mix of fibers, it must be predominantly cotton by weight to remain under this specific subheading. This code is used globally to track the trade of knitted sleepwear and ensures that the appropriate textile quotas and tariffs are applied during the importation process.

Codes often confused with 6108.31
Common mistake. A frequent misclassification occurs with HS code 6208.21, which is the designation for woven cotton nightdresses and pyjamas. The physical difference in fabric structure (knit vs. weave) is the only separator between these two codes. Another common error is using HS code 6109.10, which covers cotton T-shirts. If a long T-shirt is marketed and sold as a nightgown, it should be classified under 6108.31, but if it is a standard T-shirt used incidentally for sleep, it remains in 6109.10. Finally, dressing gowns are often confused with nightgowns but belong in 6108.91.

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).
