About HS Code 540339

This HS code serves as a residual category for single artificial filament yarns, not specifically mentioned elsewhere in heading 5403, with a linear density of less than 67 decitex, and not put up for retail sale or as sewing thread. It covers a diverse range of regenerated cellulose fibers beyond viscose rayon and cellulose acetate, such as cuprammonium rayon, modal, or lyocell, when presented as single filaments. These specialized yarns are traded globally by textile mills seeking unique properties like enhanced softness, breathability, or specific dyeing characteristics for high-end apparel, intimate wear, and technical textiles. Exporters are often innovative fiber manufacturers pushing the boundaries of artificial fiber technology. The 'n.e.c.' (not elsewhere specified) nature means careful identification of the specific artificial fiber type is crucial for correct classification.

Products Under This Code

Cuprammonium rayon filament yarn, modal filament yarn, lyocell filament yarn, specialized artificial single yarn, regenerated cellulose filament, fine denier artificial yarn

Real World Examples

Lenzing Modal Filament, Asahi Kasei Cupro, Tencel Lyocell Filament

Common Misclassification

Often confused with other specific artificial yarns (e.g., 540331 for viscose rayon) or even synthetic yarns (Chapter 54, Section XI) if the exact fiber type isn't identified, requiring detailed material analysis.

Products Classified Under 5403.39

Industry

This code belongs to the Textiles & Clothing industry.

Trade Overview

Germany, Japan, and China are significant in the production and trade of these advanced artificial yarns.
