Organo-Inorganic Compounds (NESOI)

U.S. imports of organo-inorganic compounds (nesoi) (HS 293190) totaled $51.7M in April 2026, traded with 36 countries.

Last updated: April 2026 data

Organo-silicon, organo-tin, organo-arsenic, and other mixed organic-inorganic compounds not elsewhere specified feed a wide range of industrial applications — from silicone polymer precursors and stabilizers to pharmaceutical intermediates and agrochemical actives. The US schedule subdivides this heading into seventeen 10-digit lines, distinguishing aromatic from non-aromatic structures, pharmaceutical-use compounds (2931902200), pesticide-use compounds (2931902600), and specific substances such as diphenyldichlorosilane (2931900500), dibutyltin oxide (2931909021), and the chemical-warfare-related chlorovinylarsines (2931909030, 2931909040). China, Germany, and India are the leading suppliers, with Japan and the United Kingdom also significant sources, reflecting the global distribution of fine-chemical and specialty-chemical manufacturing.

Frequently Asked Questions

How are pharmaceutical and pesticide organo-inorganic compounds classified differently within heading 293190?

The US schedule carves out aromatic organo-inorganic compounds used as drugs (2931902200) and those used as pesticides (2931902600) as separate 10-digit lines, which can affect applicable duty rates and any Section 301 exposure. Compounds not meeting those use criteria fall into residual aromatic or non-aromatic lines.

Which countries lead US imports of organo-inorganic compounds under heading 293190?

China is the top supplier, followed by Germany and India, with Japan and the United Kingdom also among the leading sources. The mix of suppliers reflects both commodity-scale organosilicon production and high-value specialty chemical manufacturing across those countries.
