5210.31.40.90 - Cheesecloth (226)

This category encompasses woven fabrics of cotton, specifically those containing less than 85% cotton by weight, mixed predominantly with man-made fibers, and weighing no more than 200 grams per square meter. These fabrics must be dyed and exhibit a plain weave construction. Furthermore, they are characterized by their yarn count, falling under number 42 or lower. This designation signifies a relatively coarser weave structure compared to finer yarns.

Within this specific level of classification, "Cheesecloth" stands apart from its siblings, "Poplin or broadcloth" (5210.31.40.20) and "Sheeting" (5210.31.40.40). While all fall under dyed, plain weave cotton fabrics of number 42 or lower, cheesecloth is distinguished by its open, porous weave, typically used for its filtration and covering properties. Poplin and broadcloth, conversely, are characterized by a finer, tighter weave, often used for shirting and apparel, while sheeting is designed for bedding and linens, generally indicating a more substantial weight and weave density than cheesecloth within the same yarn count parameters.

As this classification (5210.31.40.90) represents a leaf node within the HTS structure, there are no further subcategories. The defining characteristics for classification into this code are therefore the fabric's composition (less than 85% cotton, mixed with man-made fibers), weight (not more than 200 g/m²), dyeing status (dyed), weave type (plain weave), and yarn count (number 42 or lower), in addition to its specific designation as cheesecloth, implying its characteristic loose weave and intended applications.
