HS HEADING 5503

Synthetic staple fibres, not carded, combed or otherwise processed for spinning

In plain English

This heading covers synthetic staple fibers that have not been carded, combed, or otherwise processed for spinning. The goods are divided into specific categories based on their chemical composition, such as aramids, nylon or other polyamides, polyesters, acrylics, modacrylics, and polypropylene. Any other synthetic materials not listed in those specific groups fall into a remaining category for synthetic materials not elsewhere classified.
