Heading 5609 is a residual ('NESOI') provision and applies only when no other heading more specifically describes the article. For example, a finished hammock made of cordage might fall here if no dedicated hammock heading applies, but a fishing net made of knotted cordage belongs under heading 5608, and a rope used as a component of a finished garment or bag would follow the classification of that finished article. Always check more specific headings before defaulting to 5609.

Unlike many textile headings, heading 5609 has only one subheading (560900) and does not subdivide by fiber type. Fiber content does not change the classification within this heading, though it may still be relevant for country-of-origin rules, textile quota tracking, or applicable duty rates under trade remedy measures.
