Total Effective Rate

The United States imports substantial quantities of man-made filaments from Taiwan, with approximately $114B in total bilateral trade.

Following the Supreme Court's landmark February 20, 2026 decision striking down IEEPA tariffs, imports of man-made filaments from Taiwan are now subject to a 10% tariff under Section 122 of the Trade Act of 1974, effective February 24, 2026.

This 10% rate has a built-in expiration: Section 122 limits presidential tariff authority to 150 days, meaning the tariff expires approximately July 24, 2026 without congressional renewal.

Man-Made Filaments (HTS Chapter 54) carry an average MFN duty rate of 8% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Taiwan.

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