US Tariffs on Man-Made Filaments from China — 35% (2026)

China is a significant source of man-made filaments imports into the United States, with approximately $575B in total bilateral trade.

The current tariff framework for man-made filaments from China reflects the post-SCOTUS landscape: a 10% Section 122 tariff replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The Section 122 tariff is subject to a 150-day statutory time limit and is set to expire approximately July 24, 2026, unless Congress acts to extend or replace it. Importers should monitor legislative developments closely as this deadline approaches.

Man-Made Filaments from China are also subject to Section 301 tariffs, which range from 25% to 100% depending on the specific product classification. Section 301 tariffs were not affected by the Supreme Court ruling and remain in full effect. Combined with the Section 122 base rate, importers may face effective rates of 35% or more.

Key products in HTS Chapter 54 imported from China include Polyester filament yarn, Nylon filament yarn, Rayon filament fabric, Polypropylene yarn, Synthetic sewing thread, and Woven polyester fabric.
