No — subheading 560290 specifically covers felt that has been impregnated, coated, covered, or laminated, so these treatments keep the article within heading 5602. Classification would shift only if the lamination or coating so transforms the product that it takes on the essential character of a different article (for example, a finished gasket or a specific technical article with its own heading).

Both are fiber-based sheet structures, but needleloom felt (560210) is produced by mechanically interlocking fibers through barbed needles without a woven or knitted base, while nonwovens under heading 5603 are bonded by chemical, thermal, or mechanical means into a web. The key distinction is whether the fiber entanglement is achieved by needling (felt) or by bonding processes (nonwoven). Borderline cases may require a binding ruling.
