5212.21.60.10 - Mixed mainly or solely with wool or fine animal hair (220)

This HTS subcategory, 5212.21.60.10, specifically classifies other woven fabrics of cotton that are not exclusively cotton. The defining characteristic here is the presence of "mixed mainly or solely with wool or fine animal hair" to the extent that the fabric is still considered predominantly cotton but contains these animal fibers. The weight criterion for this classification is that the fabric must weigh more than 200 grams per square meter, and it must be unbleached.

Distinguishing this category from potential siblings involves understanding the composition. Fabrics classified under 5212.21.60.10 are primarily cotton but contain a significant proportion of wool or fine animal hair. Siblings at this level would typically cover woven cotton fabrics that are either pure cotton, or mixed with other materials besides wool or fine animal hair, or differ in their finishing (e.g., bleached, dyed, printed) or weight. The "other" designation indicates it's not a standard construction like plain weave or twill, but rather more complex or less common weaves for cotton blends.

As a leaf node within the HTS structure, 5212.21.60.10 does not have further subcategories. This means that all woven cotton fabrics weighing over 200 g/m², unbleached, and mixed mainly or solely with wool or fine animal hair, regardless of their specific weave pattern, fall directly into this classification. The practical application requires careful determination of the fiber content to confirm that wool or fine animal hair is the primary non-cotton component and that the fabric meets the weight and unbleached condition.
