5407.73.10.00 - The thread count of which per cm (treating multiple (folded) or cabled yarns as single threads) is over 69 but not over 142 in the warp and over 31 but not over 71 in the filling (620)

This HTS category, 5407.73.10.00, specifically classifies woven fabrics predominantly composed of synthetic filament yarns, meeting the "other woven fabrics" criteria of heading 5407. The defining characteristic of this subcategory is that the fabrics are constructed from yarns of different colors. Furthermore, these fabrics must exhibit a specific thread density: a warp thread count exceeding 69 but not exceeding 142 per centimeter, and a filling thread count over 31 but not over 71 per centimeter. This precise thread count, when considering folded or cabled yarns as single threads, is a critical determinant for classification under this code.

Distinguishing this category from its sibling, 5407.73.20 ("Other"), is the explicit requirement for yarns of different colors. While both fall under "other woven fabrics, containing 85 percent or more by weight of synthetic filaments," this node (5407.73.10) is reserved for those where the coloration is achieved through the use of distinct colored yarns, rather than through processes like printing or dyeing after weaving. This difference in construction and coloration method is paramount for accurate tariff application.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus remains on the precise criteria outlined in the description. Importers and exporters should meticulously verify the thread count in both the warp and filling directions, as well as confirm that the fabric is indeed constructed from yarns of different colors, to ensure correct classification under 5407.73.10.00. This level of detail is crucial for compliance and avoids potential discrepancies during customs clearance.
