U.S. exports of herbicides, antisprouting products & plant-growth regulators (nesoi) (HS 380893) totaled $83.5M in August 2026.
Importers of Herbicides, Antisprouting Products & Plant-Growth Regulators (NESOI) paid $3.2M in duties in August 2026, an effective tariff rate of 16.42% of the $19.3M imported — duty actually collected as a share of that value, not the published tariff schedule. Herbicides, Antisprouting Products & Plant-Growth Regulators (NESOI) imports of $19.3M in August 2026 ran 43% below the year-to-date monthly average of $33.8M.
Last updated: August 2026 dataChina dominates US imports under this heading, reflecting its role as the world's primary manufacturer of glyphosate and glufosinate active ingredients — both of which have dedicated 10-digit lines (3808935020 and 3808935010, respectively). Goods of Chinese origin in this heading are subject to Section 301 tariffs, a cost factor that has driven some importers to source formulated products from India, Colombia, Poland, and Germany. The heading also covers antisprouting agents and plant-growth regulators, which are regulated by EPA under FIFRA and may additionally require USDA APHIS review if derived from biological sources. Classification between the aromatic-substance line (3808931500) and the NESOI lines depends on the chemical structure of the active ingredient.

Yes. Glyphosate-based formulations classified at 3808935020 must carry a valid EPA FIFRA registration number on the label. A Notice of Arrival (EPA Form 3540-1) is required, and CBP may refer the shipment to EPA for admissibility review. Additionally, importers should verify that the specific salt or ester form of glyphosate in the product matches the registered formulation, as label deviations can trigger detention.
Section 301 tariffs apply to herbicide formulations originating in China under this heading. Importers have explored sourcing finished formulations from third countries, but must be careful that substantial transformation genuinely occurs outside China — simply blending a Chinese active ingredient in another country does not change the country of origin for tariff purposes. A binding origin ruling from CBP is advisable when the manufacturing process spans multiple countries.
