5403.39.10.00 - Textured yarn (600) 🖩

This HTS category, 5403.39.10.00, specifically classifies "Textured yarn (600)" that falls under artificial filament yarn, not intended for retail sale, and excludes sewing thread and monofilaments under 67 decitex. The term "textured yarn" in this context refers to yarns that have undergone a process to impart bulk, crimp, stretch, or a distinct surface appearance, distinguishing them from smooth filament yarns. The "(600)" designation is likely an internal reference or specific descriptor within this yarn type, crucial for precise identification.

This classification differentiates itself from its sibling category, 5403.39.90, by its specific inclusion of "Textured yarn (600)." The sibling category would encompass other types of single artificial filament yarns that are not smooth and do not fit the specific descriptor found in 5403.39.10.00, therefore covering any remaining "other" single yarns within the broader "Other yarn, single" grouping.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, classification at this level requires careful examination of the yarn's physical characteristics, specifically its artificial filament origin, its non-retail packaging, its lack of sewing thread designation, its decitex (though not limited by the <67 decitex exclusion), and most importantly, the presence of texturing processes that result in the yarn type described as "(600)."
