U.S. exports of thiocarbamates and dithiocarbamates (SITC 51542) totaled $1.9M in July 2026.
Importers of Thiocarbamates and Dithiocarbamates paid $52K in duties in July 2026 — an effective duty rate of 8.8% on $588K in dutiable value, based on actual customs collections rather than the published tariff schedule. Thiocarbamates and Dithiocarbamates imports of $919K in July 2026 ran 27% below the year-to-date monthly average of $1.3M.
Last updated: July 2026 dataDithiocarbamate chemistry underpins a large segment of the global fungicide market — compounds such as mancozeb, thiram, and zineb are widely applied in agriculture to protect crops from fungal disease. Imports of these substances may be subject to EPA pesticide registration requirements if the product is formulated for end-use application, while technical-grade material destined for further formulation follows a different regulatory pathway. Trade professionals should distinguish between technical-grade and formulated product, as classification and admissibility requirements differ accordingly.

Formulated dithiocarbamate pesticides intended for sale or distribution in the US must be registered under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) and may require an EPA establishment number. Technical-grade intermediates not sold as pesticides follow standard chemical import procedures, though EPA notification may still apply.
Thiocarbamates contain one sulfur atom in the carbamate linkage, while dithiocarbamates contain two. This structural distinction matters for classification and also for regulatory purposes, as the two groups have different toxicological profiles and may appear on different EPA or international chemical control lists.
