5112.11.30 - Of wool yarns with an average fiber diameter of 18.5 microns or less

This HTS category, 5112.11.30, specifically classifies woven fabrics of combed wool or combed fine animal hair that contain 85 percent or more by weight of wool or fine animal hair, and do not exceed 200g/m2 in weight. Crucially, this subcategory is further defined by the yarn's average fiber diameter, covering only those where the wool yarns have an average fiber diameter of 18.5 microns or less. This precision in fiber diameter is a key differentiator for this specific classification.

Within the "Of a weight not exceeding 200g/m2" grouping, 5112.11.30 stands apart from its sibling, 5112.11.60 ("Other"), by its strict requirement regarding the fineness of the wool fiber. While the sibling category encompasses other woven fabrics meeting the weight and composition criteria but not meeting the specific fiber diameter limitation, this heading is exclusively for those with exceptionally fine yarns.

This category then further divides into two subcategories to provide more granular classification. Subcategory 5112.11.30.30 is for fabrics within this fine wool yarn classification that specifically contain fine animal hair, allowing for the identification of blends. The remaining fabrics, not containing fine animal hair, fall under subcategory 5112.11.30.60, ensuring a comprehensive and accurate tariff structure for a wide range of woven wool and fine animal hair textiles.
