Last updated: April 2026 dataRetail-packaged herbicides, weed killers, antisprouting agents, and plant-growth regulators are among the highest-volume agrochemical imports entering the US, and all require EPA FIFRA registration prior to importation. Plant-growth regulators — which alter the rate or direction of plant development rather than killing pests — are classified alongside herbicides here, a grouping that sometimes surprises importers accustomed to thinking of them as distinct product categories. Glyphosate-based and other broad-spectrum herbicide formulations from multiple origins have been subject to antidumping and countervailing duty investigations, making origin and pricing documentation especially important for cost-sensitive buyers.

They must carry a valid EPA FIFRA registration identifying the antisprouting use.
Several herbicide active ingredients and formulations have been subject to antidumping and countervailing duty orders or investigations, particularly for products originating from China. Importers should check the US International Trade Commission and Commerce Department databases for active orders covering their specific active ingredient and formulation type before committing to a supply arrangement.
