Reporting Requirements for the Mercury Inventory of the Toxic Substances Control Act

On this page:

Rule Summary

On June 27, 2018, EPA published in the Federal Register a final rule to require reporting from persons who manufacture (including import) mercury or mercury-added products, or otherwise intentionally use mercury in a manufacturing process. The information collected through the new reporting requirements will be used to develop future inventories of mercury supply, use, and trade in the United States. Based on the inventory of information collected, the Agency will identify any manufacturing processes or products that intentionally add mercury and recommend actions to achieve further reductions in mercury use.

Read the final rule.

The final rule requires companies, organizations, and individuals to submit their mercury information to EPA using the online Mercury Electronic Reporting (MER) application, which is organized as a fill-in-the-blanks form with drop-down menus and lists of check-box options. The MER application can be accessed through the Agency's Central Data Exchange (CDX). Links to resources that will help companies, including small businesses, determine whether they are subject to EPA’s mercury inventory reporting requirements are provided below.

Rule History

2020 Mercury Inventory 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. Based on the information collected under the mercury inventory reporting rule, the 2020 Mercury Inventory Report identified any manufacturing processes or products that intentionally added mercury.

In December 2020, EPA updated the totals reported in its March 2020 Inventory of Mercury Supply, Use, and Trade in the United States 2020 Report. 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 additional data from five new reporters into its mercury reporting database and is making the updated 2020 totals for supply, use, and trade available in summary fashion below. 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.

Read the 2020 Mercury Inventory Report and updates.

The publication of the 2020 Mercury Inventory Report represents the completion of a suite of mandates related to elemental mercury and mercury compounds per the Frank R. Lautenberg Chemical Safety for the 21st Century Act amendments to the TSCA.

  • In August 2016, EPA released a list of five mercury compounds that are prohibited from export effective January 1, 2020.
  • In March 2017, EPA published an initial inventory report of mercury supply, use, and trade in the United States.
  • In June 2018, EPA published the mercury inventory reporting rule, which established the reporting requirements that will support the 2020 and subsequent, triennial inventories.
