CN code 620412 covers women's and girls' suits of cotton, other than knitted or crocheted. A cotton suit is an ensemble of at least two parts - a jacket and skirt or jacket and trousers - from the same cotton fabric, sold together as a commercial unit. Classification requires cotton to be the predominant fiber by weight and components to have identical composition, weave, color, and finish. Women's cotton suits are popular in summer and casual wear. The heading covers both formal business suits from densely woven cotton and lighter sets from lower-weight cotton fabrics.

Cotton suits imported into the EU are subject to labeling requirements of Regulation (EU) No 1007/2011. Each suit component should bear a composition label, though the composition must be identical. If the fabric contains an elastane addition, the label must state the share of both fibers. REACH requirements apply to reactive dyes used for cotton, formaldehyde limits, and nickel in metal components. Cotton washing and bleaching processes may leave residual chemicals subject to REACH control. The GPSR requires product traceability and risk assessment. Girls' suits face stricter mechanical safety requirements.

Women's cotton suits imported into the EU originate mainly from China, Bangladesh, India, and Turkey. Bangladesh benefits from EBA preferences enabling duty-free import. Turkey participates in the customs union. Origin rules require double transformation. Customs documentation must clearly describe the goods as a suit - an ensemble from identical fabric packaged together. Import of separate components leads to individual classification. Customs authorities verify fabric uniformity across components and may challenge suit status if components differ in material. Binding Tariff Information is recommended for regular imports.

Women's garments under CN 6204 12 imported into the EU should carry correct country-of-origin labelling. While the EU does not mandate origin labelling at Community level, consumer protection laws in Member States prohibit misleading consumers about product origin. When importing from Asia through third countries, transhipment does not change origin - the last substantial transformation determines the country of origin for customs purposes.
