Classification of other synthetic yarns under CN 5509 99

CN code 5509 99 covers other multiple or cabled yarn of synthetic staple fibres, not falling within other subheadings of heading 5509. This is a residual category covering blended yarns from synthetic staple fibres whose composition does not correspond to combinations listed in subheadings 5509 11 to 5509 92. These may include polyester-linen, polyamide-viscose, or other atypical blends. Classification requires the synthetic fibre to predominate by weight and the composition not to match any other code in heading 5509. Importers should hold a fibre composition certificate specifying the percentage of each fibre, metric number, and yarn type.

REACH requirements and textile regulations for yarn 5509 99

Importing yarn under CN code 5509 99 into the EU is subject to the Union Customs Code. Synthetic yarns are subject to REACH — dyes and finishing agents must be free from SVHC. The Textile Regulation requires fibre composition labelling. Import documentation includes a commercial invoice, fibre composition certificate, SDS, and certificate of origin.

Market and classification of blended yarn 5509 99

Blended yarn under CN code 5509 99 serves niche textile applications. Major exporters include China, India, Turkey, and Southeast Asian countries. Correct classification requires precise fibre composition determination. A laboratory fibre composition certificate is essential during customs control.
