  1. Processing and Use Reporting Threshold
  2. Full Reporting for Chemical Substances
    • 21.1. What is full reporting under CDR?

      Full reporting means that all Parts of Form U must be completed.

    • 21.2. Which chemical substances are subject to full reporting?

      Reportable chemical substances manufactured (including imported) in amounts of 25,000 pounds or more at a single site during any calendar year since the last principal reporting year (e.g., for the 2020 reporting period the last principal reporting year is 2015; therefore the years considered are 2016-2019 ) are subject to full reporting for the current principle reporting year (e.g., 2019 for the 2020 reporting period). Full reporting means that all Parts of Form U must be completed. Additionally, chemical substances that are the subject of certain TSCA actions are reportable when manufactured (including imported) in quantities of 2,500 pounds or more at a single site during any calendar year since the last principal reporting year.

      If you manufacture a chemical substance that is partially exempt from full reporting, reporting of data elements in Part II – Section D of Form U (industrial processing and use and consumer and commercial use data elements) is not required. The list of partially exempted chemical substances is found in 40 CFR 711.6(b), and is replicated on the CDR website and in EPA’s Substances Registry Services (SRS). The eCDRweb reporting tool will search SRS and report back to you if your chemical substance is partially exempted.

      See TSCA Chemical Data Reporting Fact Sheet: Chemical Substances which are the Subject of Certain TSCA Actions for information on how to identify chemical substances that are the subject of a TSCA action that affects the reporting threshold or the partial exemption status, including how to search EPA’s Substance Registry Services to identify the status of a chemical.
