Farm Groups Question Monsanto’s Glyphosate Trade Petition

By Andi Anderson

Less than a week after securing a major U.S. Supreme Court victory, Bayer’s Monsanto Co. filed antidumping and countervailing duty (CVD) petitions seeking trade action against glyphosate imports from China.

The petitions, submitted to the U.S. Department of Commerce and the U.S. International Trade Commission (ITC), allege that Chinese-produced glyphosate is being sold in the United States at unfairly low prices. Bayer is seeking duties ranging from 68.9% to 446.47% on imported glyphosate.

Monsanto said the move is intended to address “predatory trade practices and subsidized imports of glyphosate” and support long-term domestic production.

The filing has drawn criticism from several farm and commodity organizations. The American Soybean Association (ASA) expressed concerns that additional import duties could reduce market competition, increase costs, and place added financial pressure on farmers who rely on glyphosate as a key crop protection tool.

The National Association of Wheat Growers also warned that higher tariffs could further increase production costs at a time when many farmers are already facing low commodity prices and economic uncertainty.

According to market analysis from ECHEMI, Bayer, through Monsanto, operates the only fully integrated glyphosate production chain in the United States, while China accounts for more than 70% of global glyphosate manufacturing capacity.

The report noted that Chinese producers benefit from lower production costs and larger-scale operations, while U.S. manufacturers face greater cost challenges.

The U.S. Department of Commerce is expected to begin its investigation on July 20, 2026. Under current timelines, the ITC is scheduled to issue a preliminary determination by Aug. 14, 2026, with its findings subsequently forwarded to the Department of Commerce.
