U.S. exports of Dinoseb (ISO) and Its Salts (HS 290891) totaled $304K in August 2026, exported to 1 country.
Last updated: August 2026 dataDinoseb (2-sec-butyl-4,6-dinitrophenol) is a nitrophenolic herbicide and contact pesticide whose US EPA registration was cancelled in 1986 due to reproductive toxicity concerns, making commercial import for domestic agricultural use effectively prohibited. The sole recorded US import source is the United Kingdom, suggesting any trade activity relates to research, reference standards, or re-export rather than domestic end-use application. All forms enter under the single 10-digit line 2908910000. Importers should consult EPA and CBP before attempting any entry, as admissibility is tightly constrained by the cancelled registration status.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No. EPA cancelled all US registrations for dinoseb in 1986 due to reproductive and developmental toxicity. Import for domestic agricultural application is not permitted. Any import — for example, for laboratory reference standards or re-export — requires prior coordination with EPA and CBP to confirm admissibility.
A research or reference-standard import would typically require documentation establishing the non-commercial, non-agricultural end use, an EPA exemption or research authorization if applicable, and a TSCA Section 13 certification. Given the cancelled registration status, importers should obtain a binding guidance from both agencies before shipment.
