Top 5 AIs Impacted by Anticipated New Tariffs

[This blog post was originally published on January 24, 2025. It was updated on February 7, 2025 and March 4, 2025.]

Tariffs on Chinese imports, including ag chemicals, went into effect on February 4, 2025.

A month later on March 4, 2025, 25% tariffs on imports from Canada and Mexico went into effect along with an increase to 20% tariffs on Chinese imports. John Appel explains more in the video below.

With more than 580 million kg of ag chem imported into the United States every year, these tariffs will lead to price increases across a wide array of active ingredients (AIs).

1. Glyphosate
99% of glyphosate was sourced from China in 2024; there is minimal production of glyphosate in the United States.

2. Glufosinate
85% of glufosinate was sourced from China in 2024, with an additional 10% from India, and 5% from Germany; there is no production of glufosinate in the United States.
