5512.99.00.40 - Satin weave or twill weave (617)

This HTS code, 5512.99.00.40, specifically classifies woven fabrics of synthetic staple fibers that contain 85 percent or more by weight of these synthetic staple fibers. The defining characteristic of this category is its weave structure. Goods classified here are those featuring a satin weave or a twill weave, which are distinct from the other weave types found within the broader "Other" subheadings at this level.

The distinction from sibling categories is crucial for accurate classification. For instance, 5512.99.00.15 covers poplin or broadcloth, while 5512.99.00.20 relates to sheeting, and 5512.99.00.25 is for printcloth. Each of these sibling codes denotes fabrics with specific weave patterns and resulting fabric properties. This particular code, 5512.99.00.40, is reserved for fabrics that fall outside of those named weave categories and are characterized by the characteristic interlacing of threads in a satin or twill pattern, often resulting in a lustrous surface or diagonal ribbing respectively.

As this is a leaf node in the HTS structure, there are no further subdivisions. Therefore, classification under 5512.99.00.40 relies solely on confirming that the fabric is composed of at least 85% synthetic staple fibers and possesses either a satin or twill weave, and does not fit the descriptions of the preceding sibling categories. This category encompasses a range of fabrics with these specific weave structures, which may be used in various end products depending on their specific thread count, weight, and finishing.
