Total Effective Rate

Among US trading partners for man-made staple fibers, Thailand plays a notable role, with approximately $60B in total bilateral trade.

The current tariff framework for man-made staple fibers from Thailand 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 Staple Fibers (HTS Chapter 55) carry an average MFN duty rate of 8.5% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Thailand.

Key products in HTS Chapter 55 imported from Thailand include Polyester staple fiber, Acrylic staple fiber, Nylon staple fiber, Viscose staple fiber, Blended yarn, and Woven blended fabrics.
