US Tariffs on Fertilizers from China — 35% (2026)

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

As of March 2026, fertilizers imports from China face a base tariff rate of 10% under Section 122 of the Trade Act of 1974. This rate replaced the previous IEEPA reciprocal tariff following the Supreme Court's 6-3 ruling in V.O.S. Selections Inc. v. United States on February 20, 2026.

Under the Trade Act of 1974, Section 122 tariffs are limited to 150 days. The current 10% rate expires around July 24, 2026. Congressional action would be required to extend these tariffs beyond that date.

Fertilizers 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 31 imported from China include Urea, Ammonium nitrate, Diammonium phosphate, Potash (potassium chloride), NPK blended fertilizers, and Superphosphates.
