Subheading 17 of 17 in heading 2918
2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) is a chlorinated phenoxy herbicide whose US registration was cancelled by the EPA decades ago due to dioxin contamination concerns, making any import for domestic agricultural use effectively prohibited; the single 10-digit line 2918910000 covers the acid, its salts, and its esters. Trade under this heading is therefore highly restricted and typically limited to research, reference standard, or re-export purposes. India and China are the only recorded US suppliers, and importers must be prepared to demonstrate a lawful end use and comply with EPA pesticide import requirements under FIFRA.

No. EPA cancelled all US registrations for 2,4,5-T in 1985 due to contamination with 2,3,7,8-TCDD (dioxin). Importation for domestic agricultural or commercial pesticide use is therefore not permissible. Limited quantities may be imported for laboratory research, analytical reference standards, or re-export, but importers must document the lawful end use and comply with EPA's FIFRA import provisions. Consult a licensed customs broker and EPA counsel before attempting any shipment.
Despite structural similarity, 2,4,5-T (three chlorine substituents) and 2,4-D (two chlorine substituents) are classified under entirely different HS headings — 2,4,5-T here under 291891, and 2,4-D under heading 291899 (line 2918992010). Critically, 2,4-D retains active EPA registrations and is widely traded, whereas 2,4,5-T is a cancelled pesticide. Misidentifying the compound on entry documents would create both classification errors and serious regulatory exposure.
