Animal and human hair waste — including combings, clippings, and processing residues — moves in US export trade primarily as a raw material input for felt, brush, and specialty textile manufacturing. Buyers abroad value consistent fiber length and cleanliness grades, so proper baling and moisture control are standard shipper requirements. Export documentation should accurately distinguish animal species and processing state, as some hair types intersect with CITES-regulated species controls.
