5210.29.40 - Of number 42 or lower number

This HTS category, 5210.29.40, specifically classifies woven fabrics of cotton that are bleached and fall under the "Other fabrics" and "Other" classifications within the broader group of cotton fabrics containing less than 85% cotton by weight, mixed mainly or solely with man-made fibers, and weighing not more than 200 g/m². The defining characteristic for this particular subcategory is that the yarn used in the construction of these fabrics is of a specific "number" (a measure of yarn thickness) of 42 or lower. This numerical threshold signifies a coarser yarn count compared to sibling categories.

It is crucial to differentiate this category from its siblings, 5210.29.60 and 5210.29.80. While all fall under the same parent scope of bleached "other fabrics" of cotton blends, the distinction lies solely in the yarn count. Category 5210.29.60 applies to fabrics where the yarn number is between 43 and 68, and 5210.29.80 applies to fabrics with a yarn number of 69 or higher. Therefore, the coarser yarn count (42 or lower) is the sole determinant for classifying a fabric within 5210.29.40.

Within this classification, two subcategories exist to further refine the classification of these specific fabrics. Category 5210.29.40.20 encompasses a common type of weave known as "Oxford cloth," which typically utilizes this coarser yarn count. The remaining fabrics that meet the criteria of this category but are not Oxford cloth are classified under 5210.29.40.90 as "Other." This subdivision allows for specific identification of a prominent fabric type while capturing all other variations within the defined yarn count parameters.
