Hair that has been sorted by length, bleached, dyed, waved, or otherwise worked to prepare it for wig manufacture is classified here. Simply washed or degreased hair that has not undergone further processing for wig use is classified under the chapter covering raw animal or human hair, not under 6703.

No. Synthetic fibers prepared for wig-making are classified under the textile fiber chapters based on their fiber type, not under 6703. This heading is limited to human hair, animal hair (such as wool), and other textile materials specifically prepared for wig use — synthetic monofilament or tow intended for wigs goes elsewhere.
