U.S. imports of Other Organo-Nitrogen Compounds (NESOI) (HS 292990) totaled $9.4M in August 2026, imported from 23 countries.
Importers of Other Organo-Nitrogen Compounds (NESOI) paid $829K in duties in August 2026, an average duty rate of 8.84% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Other Organo-Nitrogen Compounds (NESOI) imports of $9.4M in August 2026 ran 20% below the year-to-date monthly average of $11.8M.
Last updated: August 2026 dataClassified as a residual catch-all within Chapter 29, this heading captures organo-nitrogen compounds not elsewhere specified, including cyanate esters, phosphoramidic derivatives, and several Schedule 1 and Schedule 2 chemical precursors subject to strict import controls under the Chemical Weapons Convention. The US tariff schedule subdivides the heading into aromatic and non-aromatic compounds, with dedicated lines for phosphoramidic dihalides (2929905015, 2929905018) and phosphoramidate esters (2929905020) that trigger heightened scrutiny. Germany and China are the leading suppliers, with India and South Korea also significant sources for specialty intermediates used in agrochemical and pharmaceutical synthesis.

Several non-aromatic phosphoramidic derivatives classified here — including N,N-dialkyl phosphoramidic dihalides and dialkyl phosphoramidates — are Schedule 2 or Schedule 3 chemicals under the Chemical Weapons Convention. US importers may need to file declarations with the Commerce Department's Bureau of Industry and Security (BIS) and comply with the Chemical Weapons Convention Regulations (CWCR) prior to entry.
The US schedule separates aromatic compounds (those with a benzene or similar ring structure, such as 2929900500 and 2929902000) from non-aromatic aliphatic derivatives. This distinction affects both the applicable duty rate and, in some cases, whether the compound falls under specific chemical controls. Importers should confirm the structural classification with a chemist or customs specialist before filing.
