Classification of women's cotton nightdress under HS 6108.31
HS code 6108.31 is used for women's or girls' nightdresses and pyjamas made of cotton, knitted or crocheted. This classification is part of heading 6108, which covers various types of undergarments and sleepwear. The primary factor for classification here is the intended use of the garment as sleepwear. Nightdresses are typically loose-fitting garments designed for sleeping, while pyjamas consist of a two-piece set. The use of cotton as the base material and the knitted construction are the defining technical characteristics for sub-heading 6108.31. It is important to distinguish these from lightweight summer dresses or loungewear, which may be classified under 6104 depending on their design and marketing. The 'knitted' nature of the fabric provides the comfort and breathability required for sleepwear. To fall under 6108.31, the garment must be composed of at least 50% cotton by weight. Customs authorities often look at the packaging, labeling, and general appearance to determine if a garment is truly a nightdress. Features like lace trim, soft necklines, and a lack of heavy fasteners are common indicators. If the garment is sold as a set (top and bottom), it is classified as pyjamas under the same code, provided both pieces are knitted cotton.

Codes often confused with 6108.31
Common mistake. A common misclassification is HS code 6104.42, which covers cotton knit dresses. The distinction is based on whether the garment is intended for public wear (dress) or private sleepwear (nightdress). Another error is using HS code 6208.21, which is for woven cotton nightdresses. Additionally, if the garment is a simple cotton slip, it might be wrongly classified under 6108.11 (slips and petticoats) instead of as a nightdress.

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).
