About wool; wool tops and other combed wool, in fragments

HS code 510521 covers wool tops and other combed wool in fragments. This industry plays a vital role in the global textile and apparel supply chain, providing essential raw materials for the production of a wide range of wool-based products. As a key component of the broader 51 Wool, fine or coarse animal hair; horsehair yarn and woven fabric industry, the wool tops and combed wool segment is crucial for meeting the growing demand for high-quality, natural fibers in the global market.

Production process

The production of wool tops and other combed wool involves a series of specialized processing steps. First, raw wool is scoured to remove impurities, then it is carded to align the fibers. The carded wool is then combed, a process that further straightens and aligns the fibers, removing any remaining short or coarse fibers. The resulting 'tops' are then packaged and prepared for sale or further processing by textile manufacturers.

Production inputs

The primary input for this industry is raw wool, typically sourced from sheep or other wool-bearing animals. Specialized machinery, such as carding and combing equipment, is also essential for the production of wool tops and combed wool. Additionally, the industry relies on a skilled workforce to operate the machinery and ensure consistent quality throughout the production process.

Production outputs

The main outputs of this industry are wool tops and other combed wool products, which are then consumed by a variety of downstream industries. These include the 5205 Cotton yarn and 5206 Synthetic filament yarn industries, which use wool tops as a key input for the production of blended yarns. The wool tops and combed wool produced under HS code 510521 also serve as a crucial raw material for the 5111 Woven fabrics of carded wool or of carded fine animal hair and 5112 Woven fabrics of combed wool or of combed fine animal hair industries.
