Every four years, under the Chemical Data Reporting (CDR) Rule
issued pursuant to the Toxic Substances Control Act (TSCA),
manufacturers (including importers) must provide U.S. EPA with
information on the production and use of certain chemicals in
commerce. EPA uses CDR data to support risk screening, risk
assessment, chemical prioritization, risk evaluation, and risk
management activities.
The CDR reporting requirement applies to manufacturers and
importers with production (or importation) volumes of 25,000 lbs or
more of certain chemicals, or 2,500 lbs or more of certain reduced
reporting threshold chemical substances. CDR reporting
obligations for the 2020 reporting period are triggered if the
annual production or importation thresholds at a particular
facility were met or exceeded during any of the calendar years 2016
through 2019. There are some limited exemptions, including
for small volumes or impurities.
