Wool classification under the HTS depends heavily on how far the fiber has been processed: greasy (raw) wool, degreased or scoured wool, carbonized wool, and combed wool tops each fall under different headings and may carry different duty rates. Importers should confirm the exact processing state with their supplier before filing entry documents.

Yes, certain wool products are subject to tariff-rate quotas, meaning a lower in-quota duty rate applies up to a specified volume threshold, with a higher over-quota rate applying to additional quantities. Quota fill levels and opening dates vary by product type, so importers should monitor CBP quota bulletins when planning large-volume shipments. Consult a licensed customs broker for current quota status and classification guidance.
