U.S. imports of Non-Halogenated Organophosphorus Derivatives (NES) (HS 293149) totaled $60.8M in August 2026, imported from 20 countries.
Importers of Non-Halogenated Organophosphorus Derivatives (NES) paid $8.7M in duties in August 2026, an average duty rate of 14.30% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Non-Halogenated Organophosphorus Derivatives (NES) imports of $60.8M in August 2026 ran 25% above the year-to-date monthly average of $48.7M.
Last updated: August 2026 dataChina and India together dominate US imports of non-halogenated organophosphorus derivatives not elsewhere specified, a commercially diverse basket that includes glyphosate (2931490020) — one of the world's most widely traded herbicide active ingredients — alongside phosphoramidocyanidates, phosphinates, and other specialty intermediates. Several lines within this heading, particularly those covering phosphoramidocyanidates (2931490005) and related structures, correspond to Chemical Weapons Convention Schedule 2 precursors, requiring careful end-use documentation. The glyphosate line is subject to antidumping and countervailing duty orders on imports from China, making origin and classification verification critical for cost management.

No — the antidumping and countervailing duty orders on glyphosate from China apply specifically to the glyphosate line (2931490020) and to the technical-grade acid form. Other non-halogenated organophosphorus compounds in the same heading are not covered by those orders, though they may be subject to Section 301 tariffs depending on the specific line.
The heading contains multiple residual 'NESOI' lines (e.g., 2931490055, 2931490080, 2931490085) alongside named compounds. Determining the correct 10-digit line requires confirming whether the phosphorus atom bears a methyl, ethyl, or propyl group bonded directly to it — a structural criterion that separates certain lines — and whether the compound is named elsewhere in the schedule.
