CN code 540832 covers woven fabrics of viscose rayon yarn, dyed, mixed with other fibres. Mixed viscose fabrics combine viscose properties such as softness and moisture absorption with characteristics of other fibres like polyester or cotton, achieving improved performance parameters. Dyeing takes place after weaving, providing uniform colour. These fabrics are used in apparel, decorative materials, and bed linen production. Classification requires confirmation that the fabric is made from continuous viscose yarn as the dominant component, is dyed, and contains admixtures of other fibres.

Dyed mixed viscose fabrics are subject to REACH regarding dyes and chemical substances. Different fibres in the blend may require different dyeing techniques, increasing the number of chemicals to assess. Regulation EU 1007/2011 requires full composition labelling with the percentage share of each fibre. GPSR imposes product safety and traceability obligations. Reactive dyes for viscose and disperse dyes for polyester in the blend may require separate REACH compliance testing.

The customs declaration under CN code 540832 should include full raw material composition in weight percentages, dyeing confirmation, area weight, weave, and width. Customs authorities may take samples for composition analysis. Importers should check duty rates in TARIC. Preferential rates are available under FTA agreements. Origin rules require double transformation.

CN code 5408 32 classifies dyed woven fabrics of viscose rayon containing less than 85% artificial fibres mixed with other fibres. Viscose blends are popular for combining the softness of viscose with the functional properties of other fibres. In customs classification, the percentage of artificial fibres and the type of companion fibres are decisive. Importers should provide a fibre composition certificate from an accredited laboratory.
