Last updated: August 2026 dataMercuric oxide, mercuric cyanide, and related chemically defined mercury compounds — covered under 2852101000 and 2852109000 — are tightly regulated substances used in specialty chemical synthesis, laboratory reagents, and certain electronic applications. The Minamata Convention on Mercury, to which the US is a party, imposes significant restrictions on mercury compound trade, and importers must assess whether specific compounds are subject to phase-out schedules or import prohibitions under US EPA regulations. Argentina and India are the leading suppliers to the US market under this heading. Given the hazardous nature of mercury compounds, EPA review and proper hazardous materials documentation are essential components of the import process.

The US Environmental Protection Agency (EPA) has primary jurisdiction over mercury compound imports under the Toxic Substances Control Act (TSCA) and Minamata Convention implementing regulations. Importers must file a TSCA certification and may need to demonstrate that the compound is not subject to a use prohibition or phase-out schedule before entry is granted.
A mercury compound is 'chemically defined' when it has a specific, reproducible molecular formula and consistent composition. Mixtures or preparations containing mercury compounds that do not meet this standard fall under 285290 rather than 285210. The distinction affects both the applicable tariff line and, in some cases, the regulatory filing requirements.
