6001.10 - "Long pile" fabrics:

This HTS category, 6001.10, specifically covers knitted or crocheted fabrics characterized by the presence of "long pile." The defining feature of these fabrics is a surface of loops or cut threads that are significantly longer than those found in standard pile fabrics, creating a plush, deep texture. Examples include imitation fur fabrics and deep-pile velvets, where the pile height is a crucial distinguishing factor for classification within this heading.

Within the broader category of pile fabrics, knitted or crocheted, this subheading differentiates itself from its siblings by focusing exclusively on the length of the pile. While other categories might cover "looped pile fabrics" (which have uncut loops) or "other" pile fabrics that may have shorter pile or different construction methods, 6001.10 is dedicated to those where the pile has a pronounced length, contributing to a distinct tactile and visual characteristic.

The subcategories under 6001.10 further refine the classification based on the material composition of the fabric. The code 6001.10.20.00 is designated for "long pile" fabrics made predominantly of man-made fibers, such as polyester, nylon, or acrylic. Conversely, 6001.10.60.00 encompasses "other" long pile fabrics, which would typically include those primarily composed of natural fibers like wool or cotton, or blends where natural fibers are dominant.
