5106.10.00.90 - Other (400)

This HTS category, 5106.10.00.90, specifically covers yarn of carded wool, not put up for retail sale, that contains 85 percent or more by weight of wool and does not meet the criteria of sibling categories concerning average fiber diameter. These yarns are typically intended for industrial use in manufacturing processes rather than direct consumer purchase. Examples include yarns used in the production of carpets, upholstery, and other textile articles where specific fiber diameter is not the primary distinguishing factor for classification.

This classification distinguishes itself from the sibling category 5106.10.00.10 by the absence of a specified average fiber diameter of not less than 34.40 microns. While both categories fall under yarn of carded wool containing at least 85% wool, 5106.10.00.10 is for yarns with coarser wool fibers, whereas this category 5106.10.00.90 encompasses all other such yarns, regardless of their average fiber diameter, as long as they meet the general composition requirement.

As this is a leaf node within the HTS, there are no further subcategories to detail. Classification within this specific code is determined by the material composition (85% or more wool), the processing method (carded yarn), its presentation (not for retail sale), and the exclusion from more specific diameter-based sibling classifications.
