5407.52 - Dyed:

This HTS category, 5407.52, specifically encompasses woven fabrics of synthetic filament yarn that are dyed, and comprise 85 percent or more by weight of textured polyester filaments. The "dyed" designation is a critical differentiator, indicating that the fabric has undergone a coloring process after its initial weaving.

Distinguishing this category from its siblings, 5407.52.00 is for dyed fabrics, whereas 5407.51.00 covers unbleached or bleached fabrics, and 5407.54.00 pertains to printed fabrics. While 5407.53.00 deals with dyed fabrics of yarns of different colors (meaning the dyeing occurred prior to weaving into a patterned fabric), 5407.52.00 focuses on fabrics where the entire fabric has been dyed after weaving.

The subcategories within 5407.52 further refine the classification based on specific physical characteristics. 5407.52.05.00 provides detailed thread count and width parameters, allowing for precise classification of certain narrow or tightly woven fabrics. The remaining subcategory, 5407.52.20, serves as a residual category for other dyed, textured polyester filament woven fabrics that do not meet the specific criteria of the preceding subcategory.
