Importers of Thiuram Mono-, Di-, or Tetrasulfides paid $78K in duties in April 2026 — an effective duty rate of 23% on $334K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataThiuram sulfides occupy a specialized niche as rubber vulcanization accelerators and, in some formulations, as fungicidal active ingredients — thiuram disulfide (thiram) is a well-known example used in both rubber processing and seed treatment. The sulfur-chain length (mono-, di-, or tetra-) determines both the chemical reactivity and the end-use suitability, making precise product specification critical for buyers in the rubber and agrochemical industries. Importers should confirm whether the specific thiuram compound is subject to EPA pesticide registration requirements if it is formulated for agricultural use.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Thiuram monosulfides and disulfides are primarily used as ultra-accelerators in rubber vulcanization, imparting fast cure rates. Tetrasulfides are slower-acting and often preferred where controlled crosslink density is needed. Buyers should specify the exact compound to ensure the product meets their processing requirements.
Trade-remedy exposure depends on the specific compound and country of origin. Importers should check current antidumping and countervailing duty orders maintained by the Department of Commerce, as specialty chemical categories can be subject to such measures, particularly for shipments from major chemical-producing countries.
