Last updated: August 2026 dataThe 'not elsewhere specified or included' residual heading for carded or combed synthetic staple fibers captures specialty polymer fibers — such as those based on polyvinyl alcohol, polylactic acid, or other engineered synthetics — that do not fit the named polyester, polyamide, acrylic, or polypropylene headings. All US imports enter under 5506900100. Correct classification requires confirming that the fiber's polymer base is not covered by a more specific heading in Chapter 55, making fiber chemistry documentation essential at entry.

Fibers based on polymers not specifically enumerated in Chapter 55 — such as polylactic acid (PLA), polyvinyl alcohol (PVA), or certain bicomponent specialty fibers — may fall here when they have been carded or combed for spinning. The NESOI designation is a residual catch-all, so importers should verify that no more specific heading applies before using 5506900100.
Section 301 tariff applicability is determined by the HTS classification, not the polymer type. Fibers classified under 5506900100 and originating from China are subject to Section 301 measures applicable to that tariff line. Importers should confirm the current Section 301 list status of this subheading with a licensed customs broker, as list coverage and rates are subject to revision.
