U.S. exports of Inorganic and Organic Mercury Compounds (Excluding Amalgams) (SITC 52496) totaled $260K in August 2026.
Inorganic and Organic Mercury Compounds (Excluding Amalgams) imports of $10K in August 2026 ran 89% below the year-to-date monthly average of $87K.
Last updated: August 2026 dataMercury compounds—whether inorganic salts such as mercuric chloride or organomercury derivatives—face stringent regulatory scrutiny at US ports of entry due to mercury's classification as a hazardous substance under EPA and TSCA frameworks. The Minamata Convention on Mercury, to which the US is a party, imposes supply-chain transparency obligations that affect import documentation and end-use declarations. Amalgams are explicitly excluded and classified separately. Trade professionals should be prepared for enhanced EPA review and verify that the specific compound is not subject to import restrictions or phase-out schedules under domestic mercury management regulations.

Yes. As a Minamata Convention party, the US requires that certain mercury compound imports be accompanied by documentation confirming the intended use and that the use is not prohibited or restricted under the Convention. EPA may require additional consent or notification procedures depending on the compound and its application. Importers should consult a licensed customs broker and confirm current EPA guidance before shipment.
Amalgams—alloys of mercury with other metals—are treated as metallic mixtures rather than discrete chemical compounds, so they are classified under a separate inorganic compounds residual heading. The distinction matters because amalgams have different duty treatment and regulatory pathways than pure mercury salts or organomercury compounds.
