Sorted rags and scrap have been separated by fiber type, color, or intended use prior to export, making them more suitable for direct industrial processing. Unsorted lots, classified under 631090, are mixed and require further sorting by the importer or processor. The sorting condition must be verifiable from the shipment's physical state and commercial documentation.

Worn-out articles of twine, cordage, or rope that are no longer fit for their original purpose classify under 6310 as waste or worn-out articles. Cordage that remains serviceable and is traded as a functional product belongs under the heading for twine, cordage, and rope, not here.
