Carbonized Romney Wool Fibers from Japan
Romney wool fibers undergo carbonization to break down and remove vegetable contaminants, yielding clean fiber for industrial textile uses. This matches HTS 5101.30.70.00 for other carbonized wool, not carded/combed, with clean yield assessed as entered per chapter notes. Commonly used in heavy-duty felts and mats.

Import Tips
• Retain carbonization process records; Customs may request proof that fibers weren't pre-combed to confirm 5101 status
• Calculate and declare clean yield precisely—errors lead to penalties under absolute clean content rules
