5507.00.00.00 - Artificial staple fibers, carded, combed or otherwise processed for spinning

This HTS category, 5507.00.00.00, encompasses artificial staple fibers that have undergone specific processing steps designed to prepare them for the spinning of yarn. This includes fibers that have been carded, combed, or otherwise mechanically or chemically treated to align, separate, and prepare the individual filaments into a sliver or roving. The key distinguishing feature of this classification is the post-production processing beyond the initial creation of staple fibers, making them ready for further textile manufacturing.

Unlike other categories within Chapter 55 which may cover man-made staple fibers in their raw or unprocessed state (e.g., synthetic staple fibers not yet carded or combed), this heading specifically targets fibers that have been enhanced for spinning. While other Sections and Chapters of the HTS deal with different types of materials (e.g., Section I for live animals, Section VI for chemical products), this category is exclusively focused on intermediate textile materials derived from man-made filaments.

As this is a leaf node within the HTS structure, there are no further subcategories or subdivisions under 5507.00.00.00. Therefore, classification under this heading is definitive for artificial staple fibers that have been carded, combed, or otherwise processed for spinning. Examples would include polyester staple fiber that has undergone carding and combing to form a web or sliver, or acrylic staple fiber prepared for spinning into yarn.
