Chemical Data Reporting (CDR)

CDR Instructions and Guidance


June 19, 2014 -- EPA amended the list of chemical substances that are partially exempt from reporting additional information by adding three chemicals in response to a petition the Agency received. The chemicals are 1,3-Propanediol (CAS RN 504-63-2); Palm Kernel Oils (CAS RN 8023-79-8); and Bentonite, (Acid Leached) (CAS RN 70131-50-9). Learn more. Read the Federal Register notice.

Late submission? The submission period for the 2012 CDR ended on August 13, 2012. EPA continues to provide support to companies through a range of resources:

On this page you will find instructions and guidance on submitting information to EPA pursuant to the Chemical Data Reporting (CDR) rule:

Information about the Next CDR Reporting in 2016

The submission period for the 2016 CDR will be from June 1, 2016, to September 30, 2016.

The Agency will be issuing guidance documents to better explain the requirements and is encouraging you to submit questions and comments on the 2016 reporting cycle to the CDR inbox available at eCDRweb@epa.gov.

Please be advised that manufacturers (including importers) need to report production volume information for calendar years 2012, 2013, 2014, and 2015. While submitters will not report to EPA until 2016, they should start keeping track of their production volumes for these four years. For the 2016 CDR, the principal reporting year will be calendar year 2015. Full manufacturing, processing, and use information will be required only for 2015.

EPA would like to make the 2016 reporting process as smooth as possible for submitters. Below are the requirements for the 2016 CDR:

  • Manufacturers (including importers) will be required to report if, for any calendar year since 2011, a chemical substance was manufactured (including imported) at a site in production volumes of 25,000 lbs. or greater.
  • The reporting threshold for processing and use information will be 25,000 lbs. Note: This is lower than the 100,000 lb threshold for processing and use information required for the 2012 CDR.
  • The reporting threshold will be 2,500 lbs. for chemical substances that are:
    • Subject of a rule proposed or promulgated under TSCA section 5(a)(2), 5(b)(4), or 6
    • Subject of an order issued under TSCA section 5(e) or 5(f)
    • Subject of relief that has been granted under a civil action under TSCA section 5 or 7

When is Reporting Required?

The submission period for the next CDR will begin on June 1, 2016. The CDR rule required manufacturers, including importers of certain chemical substances included on the TSCA Chemical Substance Inventory, to report information on chemicals manufactured (including imported) in volumes of 25,000 lbs. or more at their site during any calendar year since 2011.

How did Chemical Data Reporting (CDR) Change for 2012 Reporting?

EPA published the Chemical Data Reporting Final Rule which was proposed in the Federal Register as the Inventory Update Reporting (IUR) Modifications Rule. The final rule delineates a number of improvements for 2012 reporting, including requiring electronic reporting, via the e-CDRweb, and making reporting easier and more accessible to all potential reporters. The rule also modifies the reporting of manufacturing, processing and use data for most chemicals and makes changes to specific data elements, including requiring submission of production volume for calendar year 2010. The rule also requires that manufacturers (including importers) provide a greater amount of substantiation for confidential business information claims. Read the fact sheet (PDF) (4 pp, 23K).

Reporting Electronically: Registration in the Central Data Exchange (CDX)

You were required to submit your CDR Form U electronically during the 2012 CDR submission period. To enable electronic submissions, you need to:

  • Register on CDX: To register for CDR reporting, go to the CDX website and register under the program "Submissions for Chemical Safety and Pesticide Programs (CSPP)." If you were previously registered on CDX for e-TSCA, e-PMN, or TRI, you are able to add the CDR reporting flow to your current registration.
  • Access e-CDRweb: The Agency-provided electronic reporting tool used to complete Form U is now available. Once you have registered in CDX, you will be able to access e-CDRweb.
  • Submit your completed Form U: EPA began accepting Form U submissions on February 1, 2012. Completed forms were due by August 13, 2012.

Webinars to Assist 2012 Submitters

EPA hosted a webinar to assist industry with the registration process in CDX for the 2012 CDR rule on February 8, 2012. The webinar demonstrated the registration process for Authorized Officials and Support using EPA's CDX. Download the presentation (PDF) (48 pp, 1.4M).

EPA hosted a webinar to assist industry with the reporting process for the 2012 CDR rule on November 16, 2011. The webinar was intended for industry stakeholders who will be reporting in response to the CDR requirements. The webinar included an overview of the 2012 reporting requirements, a discussion of joint reporting, a discussion of considerations related to the reporting of by-products and updated information about registering for electronic reporting and for using the electronic reporting tool. At the conclusion of the presentation participants were able to phone in with questions concerning the rule. Those who were not able to have their questions answered during the webinar were encouraged to send their questions to ecdrweb@epa.gov.

EPA hosted a webinar to demonstrate the e-CDR web tool on September 23, 2011. The webinar introduced industry stakeholders to e-CDRweb in preparation for the preview period. NOTE: the opportunity to test the reporting tool is now closed.

The final version of e-CDRweb for 2012 CDR submissions is based on the final rule. View the XML schema (primary and joint submissions).

Petitions for Partial Exemption

EPA maintains a list of partially exempt chemicals for which the CDR processing and use information is of "low current interest" at 40 CFR 711.6(b)(2)(iv). Manufacturers of these listed chemicals are exempt from reporting the processing and use information required by 40 CFR 711.15(b)(4). Chemical substances are included on this list only if EPA has determined that there is low current interest in the processing and use information for that substance.

EPA may amend the list of partially exempt chemicals on its own initiative or in response to a request from the public. The public may submit a petition to request that a chemical be added to or removed from the partial exemption.

EPA amended the list of chemical substances that are partially exempt from reporting additional information by adding three chemicals in response to a petition the Agency received. The chemicals are 1,3-Propanediol (CAS RN 504-63-2); Palm Kernel Oils (CAS RN 8023-79-8); and Bentonite, (Acid Leached) (CAS RN 70131-50-9). Read the Federal Register notice.

Who can Submit a Petition?

A petition may be submitted by any person, regardless of whether the person manufacturers, imports, or uses the chemical, or is otherwise interested in the chemical. When evaluating the petition, EPA will consider the production volume and use information for all manufacturing or importing sites and all uses. This information is not restricted to the submitting site. Considerations used by EPA when deciding whether to grant the petition are listed at 40 CFR 711.6(b)(2).

Note: The partial exemption listing is chemical-specific, not site- or use-specific. Therefore, when a chemical is listed under the partial exemption in 40 CFR 711.6(b)(2), all manufacturers (including importers) are exempt from reporting the processing and use information required under 40 CFR 711.15(b)(4) for the listed chemical substance.

How Do I Submit a Petition?

Your petition to amend the partial exemption chemical list must be submitted in writing and must contain the identity of the chemical in question, as well as its Chemical Abstract Service (CAS) Registry Number. If a CAS Registry Number is not known to or reasonably ascertainable by you (the petitioner), an EPA-designated Accession Number for confidential substances or a premanufacture notice (PMN) case number can be submitted in lieu of a CAS Registry Number.

Your petition must also contain a written rationale for the request that provides sufficient specific information addressing the considerations listed below and in 40 CFR 711.6(b)(2)(ii), including citations and relevant documents, to demonstrate to EPA that the collection of the information in 40 CFR 711.15(b)(4) for the chemical in question either is or is not of low current interest. If a request related to a particular chemical is resubmitted, any subsequent request must clearly identify new information contained in the request. EPA may request other information that it believes necessary to evaluate the request. EPA will issue a written response to each request within 120 days of receipt of the request. This response will provide a status report for the petition review.

What Happens to My Petition Once I Submit It?

EPA has established a review process for the petitions. There are several steps in this review process and at any place in this process EPA may contact the petitioner for clarification or additional information. The petitioner may also submit additional information to its petition at any time before EPA issues a final decision. No later than 120 days after receipt of the petition, EPA must issue a response to the petitioner. The response need not have EPA's final decision. However, if EPA does make a final decision before the 120 days has passed, EPA may notify the petitioner immediately.

In making its determination of whether this partial exemption should apply to a particular chemical substance, EPA will consider the totality of information available for the chemical substance in question, including but not limited to, one or more of the following considerations:

  • Whether the chemical qualifies or has qualified in past IUR collections for the reporting of the information described in 40 CFR 711.15(b)(4).
  • The chemical substance's chemical and physical properties or potential for persistence, bioaccumulation, health effects, or environmental effects (considered independently or together).
  • The information needs of EPA, other federal agencies, tribes, states, and local governments, as well as members of the public.
  • The availability of other complementary risk screening information.
  • The availability of comparable processing and use information.
  • Whether the potential risks of the chemical substance are adequately managed.
