Access Chemical Data Reporting Data

EPA has collected Chemical Data Reporting data since 1986. It was previously collected under the Inventory Update Reporting. Collections occur approximately every four years and reporting requirements changed from collection to collection. On this page you can access information from the latest collections, occurring in 2006, 2012, 2016, and 2020. View a summary of CDR requirements for 2006 to 2020.

On this page:

• 2020 CDR data
• 2016 CDR data
• 2012 CDR data
• 2006 IUR data
• 2002-1986 IUR data

For information on what to consider while using the CDR data and changes from 2016 to 2020, see Using the CDR Database and Interpreting the CDR Data.

2020 CDR Data (up-to-date as of April 2022)

During the 2020 reporting cycle, CDR information was provided by manufacturers (including importers) for about 8,649 individual chemicals. 

EPA carried out the most extensive data quality control efforts to date to identify potential reporting errors. Because of competing TSCA priorities, such as other data gathering efforts and activities underway to use CDR data and longstanding resource issues, EPA’s data quality efforts took a longer amount of time than normal. 

The data currently includes company and site information, manufacturing (including import) information, production volume, and processing and use data. 

This publication includes chemicals which lost their confidential status on the TSCA Inventory because one or more manufacturers reported the chemical identities as non-confidential during the 2012, 2016, and/or 2020 CDR reporting periods. 

Reporting thresholds for the 2020 CDR were triggered based on the volumes for any calendar year since the last principal reporting year. For 2020, reporting was triggered based on the production volume for 2016, 2017, 2018 or 2019.

2016 CDR Data (updated May 2020)

During the 2016 reporting cycle, CDR information was provided by manufacturers (including importers) for 8,707 individual chemicals.

Reporting thresholds for the 2016 CDR were triggered based on the volumes for any calendar year since the last principal reporting year. For 2016, reporting was triggered based on the production volume for 2012, 2013, 2014 or 2015. In contrast, reporting for 2012 was triggered based only on the production volume for 2011. 

For the 2016 CDR, a lower reporting threshold of 2,500 lbs. or more became effective for chemical substances subject to certain TSCA actions.  In addition, unless partially exempted, processing and use information was required for all reported chemical substances at the 25,000-lb. threshold (or 2,500 lbs. if subject to certain TSCA actions), whereas for the 2012 CDR, processing and use information was only required for chemicals with production volumes of 100,000 lbs. or greater.

2012 CDR Data

During the 2012 reporting cycle, CDR information was provided by manufacturers (including importers) for 7,970 individual chemicals.

2006 IUR Data

Before August 2011 the CDR Rule was called the Inventory Update Reporting (IUR) Rule. The change was effective with the publication of the Inventory Update Reporting Modifications; Chemical Data Reporting Final Rule in August 2011.

• Get the non-confidential 2006 downloadable database The 2006 IUR data summary report includes information about chemicals manufactured or imported in quantities of 25,000 pounds or more at a single site during calendar year 2005. In addition to the basic manufacturing information collected in previous reporting cycles, the 2006 cycle is the first time EPA collected information to characterize exposure during manufacturing, processing and use of organic chemicals. The 2006 cycle also is the first time manufacturers of inorganic chemicals were required to report basic manufacturing information.

2002-1986 IUR Data

Before the 2006 IUR, information reported to EPA was much more limited in scope. Reported information covered organic chemicals manufactured and imported in volumes of 10,000 pounds or more at an individual site and included only basic manufacturing data, such as a chemical's production volume (information on inorganic chemicals or about processing and use of the chemicals were not yet required to be reported).

• Get the non-confidential 2002-1986 downloadable database
  • This non-confidential database includes company, site, and manufacture/import information for IUR cycles 1998 and 2002. This database also contains chemical-specific nationally aggregated production volume data for all reporting cycles between 1986 – 2006. Prior to 1998, parent company and site-specific information was not released publicly.
  • In general, production volumes were not required to be reported to the Agency for years 1980-1984, 1986-1988, 1990-1992, 1994-1996, 1998-2000, 2002-2004, and 2006-2009.  For all reporting years 1986 – 2006, the production volumes applied to (actually occurred during) either the preceding calendar year or previous corporate fiscal year (e.g., 1985 for 1986, 2001 for 2002, 2005 for 2006, etc.)
