Last updated: August 2026 dataTextured synthetic filament yarns not covered by the nylon, polyester, or polypropylene headings — including polyethylene and other specialty polymer yarns — fall here as a residual category. China leads US supply, followed by India and Vietnam. The five 10-digit lines under this heading separate polyethylene single and multiple constructions (5402393110 and 5402396110) from all other non-enumerated synthetic polymers (5402393190 and 5402396190), with China-origin entries subject to Section 301 tariffs, making precise polymer identification on entry documents essential to avoid misclassification into or out of this residual heading.

Beyond polyethylene, this heading captures textured yarns of polymers such as polylactic acid (PLA), polytrimethylene terephthalate (PTT), and other engineered fibers that do not fit the enumerated headings for nylon, polyester, or polypropylene. As bio-based and high-performance synthetic fibers expand commercially, this residual heading is increasingly relevant for novel fiber types.
Lines 5402393110 and 5402396110 are dedicated to polyethylene textured filament yarn, while 5402393190 and 5402396190 cover all other non-enumerated synthetics. Entering polyethylene yarn on the 'other' line rather than the polyethylene-specific line constitutes a misclassification that could trigger a CF-28 or penalty action. Importers should confirm the polymer identity with the manufacturer's material safety data sheet or a fiber content certificate.
