U.S. imports of ureines and their derivatives; salts thereof (HS 292421) totaled $1.6M in April 2026, traded with 13 countries.
Importers of Ureines and Their Derivatives; Salts Thereof paid $206K in duties in April 2026 — an effective duty rate of 15% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ureines and Their Derivatives; Salts Thereof imports of $1.6M in April 2026 ran 13% below the year-to-date monthly average of $1.8M.
Last updated: April 2026 dataUreines — cyclic urea derivatives — are a structurally diverse class that includes phenylurea herbicides such as monuron (3-(p-chlorophenyl)-1,1-dimethylurea, line 2924210400) and a range of aromatic and non-aromatic pesticide intermediates. The US schedule segments this heading into aromatic pesticide ureines, other cyclic ureines tied to US Note 3 to Section 6 production status, and non-aromatic derivatives, each carrying distinct duty treatment. China and India are the leading suppliers, consistent with their dominant role in agrochemical intermediate manufacturing, with Israel, Czech Republic, and Germany serving as sources for higher-specification or pharmaceutical-grade variants.

US Note 3 to Section VI of the HTS identifies specific chemicals that are subject to a separate duty rate when they are products of a US manufacturing process (i.e., produced domestically and re-imported). Lines 2924212000 and 2924214500 distinguish between ureines that qualify under that note and those that do not, so importers must determine whether the goods originate from a US-origin production process to select the correct tariff line.
Bulk phenylurea chemical intermediates imported for further processing into registered pesticide products generally require TSCA certification at entry rather than a standalone EPA pesticide registration. However, if the substance is imported as a formulated herbicide ready for end use, FIFRA registration is required. The distinction between technical-grade intermediate and finished pesticide formulation is the key classification trigger.
