CN code 620423 covers women's and girls' ensembles of synthetic fibers, other than knitted or crocheted. Synthetic fibers include polyester, polyamide, and acrylic. An ensemble must consist of at least two clothing articles from the same or complementary synthetic fabric, forming an outfit for wearing together. Classification requires the synthetic fiber to be the predominant fiber by weight. Synthetic ensembles are popular in casual, sportswear, and workwear from woven fabrics. Components must be packaged and sold together as a commercial unit.

Synthetic fiber ensembles are subject to labeling requirements of Regulation (EU) No 1007/2011. REACH requirements apply to disperse dyes, PFAS substances in finishes, and formaldehyde. Metal components must comply with nickel limits. The GPSR requires traceability and risk assessment. Girls' ensembles face stricter mechanical safety requirements. Flame retardant substances in synthetic fabrics may face additional REACH restrictions.

Women's synthetic fiber ensembles imported into the EU originate from China, Vietnam, Bangladesh, and Turkey. Customs documentation must confirm ensemble status. Customs authorities verify the Note 3(b) definition. Origin rules require double transformation. Tariff preferences depend on the country of origin. Separate component imports are classified individually. TARIC database verification is recommended.

Woven women's garments under CN 6204 23 are classified within heading 6204, covering suits, ensembles, jackets, dresses, skirts and trousers made from woven fabrics. The key classification factor is distinguishing from Chapter 61 (knitted). Importers must declare precise fibre composition as subheadings differentiate duty rates by material - wool, cotton, synthetic and artificial fibres each carry different TARIC duty rates.
