The purpose of Chemical Data Reporting (CDR), formerly known as Inventory Update Reporting (IUR), is to collect quality screening-level, exposure-related information on chemical substances and to make that information available for use by EPA and, to the extent possible, the public. The rule requires manufacturers and importers to provide the Agency with information on the production and use of chemicals in commerce in large quantities. The CDR data constitute the most comprehensive source of basic screening-level, exposure-related information on chemicals available to EPA.
How Does EPA Use the CDR Data?
EPA uses the data to support risk screening, assessment, priority setting and management activities. Processing and use information reported in 2012 will help EPA screen and prioritize chemicals for the purpose of identifying potential human health and environmental effects. Collecting the information every four years will assure that the public has timely access to current and improved data. This information will also provide the public with greater access to a wide range of information on those chemicals that are produced in large quantities. Improved data will enhance the Agency's ability to more effectively identify and address potential chemical risks.
For the 2012 CDR submission period, manufacturers (including importers) were required to report full manufacturing data for calendar year 2011 and production volume only for calendar year 2010 for all reportable chemical substances when 2011 site-specific production volume equaled or exceeded 25,000 lbs. Manufacturers (including importers) were required to report processing and use data for calendar year 2011, for all reportable chemical substances when 2011 site-specific production volume equaled or exceeded 100,000 lbs.

How to Submit CDR Data
The CDR regulation requires all companies to report data electronically using e-CDRweb, the CDR web-based reporting tool, and EPA's Central Data Exchange (CDX) system.
Businesses required to comply with the CDR regulation should have a thorough understanding of the TSCA Inventory and the criteria used to determine the listing of a substance on the TSCA Inventory.
Read the latest final Chemical Data Reporting (CDR) Rule issued August 2, 2011.
In 1977, the EPA promulgated a rule under the Toxic Substances Control Act (TSCA) section 8(a), 15 U.S.C. 2607(a), to compile and keep current an inventory of chemical substances in commerce in the U.S. This inventory is called the TSCA Chemical Substance Inventory (TSCA Inventory).
Regulations to amend and update the inventory were issued in 1986, 2003, 2005, and most recently in 2011.
These regulations addressed the range of chemicals and plant sites reporting, the type of data reported, the production volume threshold, and made other adjustments.
