Last updated: August 2026 dataChina, Germany, and India are the leading US import sources for this broad residual heading, which spans organosilicon compounds (2931909010), organotin stabilizers such as dibutyltin oxide (2931909021) and tetrabutyltin (2931909025), chlorovinylarsines (2931909030–2931909040), aromatic compounds used as drugs (2931902200) or pesticides (2931902600), and a range of boron, silicon, and phosphorus-based specialty chemicals. The chlorovinylarsine lines (lewisite precursors) are subject to CWC controls, while the organotin lines serve the PVC stabilizer and catalyst markets. China-origin imports across several lines in this heading are subject to Section 301 tariffs, making supplier diversification and tariff engineering a priority for procurement teams.

Section 301 tariff applicability is determined at the 10-digit HTS line level, and coverage within this heading is not uniform. Importers should verify each specific line — for example, organosilicon compounds (2931909010) versus organotin compounds (2931909021, 2931909025) — against the current Section 301 list, as some lines may be excluded or subject to different rates.
The distinction turns on the compound's primary commercial use: line 2931902200 covers aromatic organo-inorganic compounds used as pharmaceutical active ingredients or intermediates, while 2931902600 covers those used as pesticide active ingredients. A compound with dual potential uses is classified based on its principal use as presented at importation, supported by documentation such as a product specification sheet or safety data sheet.
