Updated Totals for the Inventory of Mercury Supply, Use, and Trade in the United States 2020 Report

December 2020

The U.S. Environmental Protection Agency (EPA) is updating totals reported in its Inventory of Mercury Supply,
Use, and Trade in the United States 2020 Report.

On March 30, 2020, EPA published the first in a series of triennial reports on the supply, use, and trade of mercury
in the United States, supported by the Agency's mercury inventory reporting rule. Consistent with EPA's goals to
ensure that all persons required to report are aware of the new reporting requirements and that the mercury
inventory accurately describes the supply, use, and trade of mercury in the United States, EPA accepted late
submissions from a number of reporters and conducted outreach to additional potential reporters, some of whom
were either determined to not need to report or have subsequently submitted data to the Agency. EPA has now
incorporated the additional data into its mercury reporting database and is making the updated 2020 totals for
supply, use, and trade available in summary fashion below.

The updates are reflected in the revised summary table for supply, use, and trade of mercury in the reporting
year of 2018 (below). Additional data were provided by five reporters and increased totals were primarily linked
to recycling/retorting elemental mercury and manufacturing, which includes importing, dental amalgam
and switches, relays, sensors, and valves. The Agency is not re-issuing the 2020 report; however, it will use the
newly submitted data to inform the 2023 inventory report, as well as ongoing activities related to mercury.
