CN code 620690 covers women's or girls' blouses made from woven fabrics of textile materials other than silk, wool, cotton or man-made fibres, classified under heading 6206 of the Combined Nomenclature. This subheading serves as the residual category for blouses made from linen, hemp, ramie, jute and other natural fibres, as well as blends where none of the fibres covered by subheadings 620610–620640 constitutes the predominant component by weight. Classification requires that the garment be made from woven fabric rather than knitted or crocheted material, which would fall under Chapter 61. The fibre composition must be determined in accordance with Regulation (EU) No 1007/2011 on textile fibre names. Blouses may feature front, back or overhead openings, provided their cut and finish indicate use as outerwear covering the upper body.

Importing women's blouses under CN code 620690 into the European Union requires compliance with the Textile Regulation (EU) No 1007/2011, mandating full fibre composition labelling in the official language of the country of sale. Labels must state the percentage of each fibre in descending order. REACH Regulation (EC) No 1907/2006 restrictions apply to azo dyes releasing aromatic amines (Annex XVII entry 43), formaldehyde content and nickel release from metallic components such as buttons or hooks. The General Product Safety Regulation (EU) 2023/988 (GPSR) requires importers to maintain technical documentation and ensure product traceability throughout the supply chain. Country of origin must be indicated on packaging. Products from certain third countries may be subject to textile surveillance mechanisms or quantitative restrictions.

The customs declaration for blouses under CN code 620690 should specify the gender of the intended wearer, the dominant textile material (e.g. linen, hemp), the fastening method and the garment's purpose. Commercial documentation must include an invoice stating unit price, quantity and composition. To benefit from preferential duty rates, importers should present valid proof of origin such as EUR.1 certificates under FTA agreements, Form A certificates under GSP or invoice declarations. Importers should verify in the TARIC database whether anti-dumping duties or safeguard measures apply for the specific country of origin. For EU exports, woven textile blouses are generally not subject to export control restrictions. While size labelling is not regulated at EU level, use of EN 13402 European sizing standards is recommended for cross-border trade facilitation.

CN 6206 90 is a residual subheading covering women's blouses of textile materials other than silk, wool, cotton and synthetic fibres. This includes blouses of artificial fibres (viscose, modal, lyocell) and linen or other natural plant fibres. Viscose blouses represent the largest segment, valued for softness and print quality. The erga omnes duty rate is 12%. Correct fibre identification is critical for classification purposes.
