A made-up net is one that has been cut to shape, assembled, or finished for a specific end use — such as a fishing net with floats, weights, or attachment hardware, or a safety net cut and edged for installation. Netting sold in bulk rolls or unfinished lengths may instead be classified as knotted netting of twine under the same heading, but the distinction between a finished article and a semi-finished material can affect both classification and applicable duty rate.

Knotted netting of man-made textile materials not used as fishing nets falls under subheading 560819, which covers 'other' made-up nets and knotted netting of man-made textiles. A cargo net that is knotted and made of synthetic fiber would typically fall here. However, if the net is constructed by a different method (such as welded or woven rather than knotted), it may fall under a different provision, and a binding ruling is advisable for non-standard constructions.
