(Updated November 10, 2020)

These Frequent Questions (FQs) are intended to clarify the reporting requirements for Chemical Data Reporting for the 2020 reporting period.

These FQs should be used for information only and are not a substitute for the Toxic Substances Control Act (TSCA) Chemical Data Reporting (CDR) rule. You should carefully review the CDR regulations, located at 40 CFR Part 711, for specific information on how to comply with CDR requirements.

If you need more help, visit EPA's Chemical Data Reporting website at www.epa.gov/cdr, contact EPA's TSCA Hotline at tsca-hotline@epa.gov or 202-554-1404, or send an email to eCDRweb@epa.gov.
