Subpart B—Applicability 

§ 720.22 Persons who must report. 

(a)(1) Any person who intends to manufacture a new chemical substance in the United States for commercial 

purposes must submit a notice unless the substance is excluded under §720.30. 

(2) If a person contracts with a manufacturer to manufacture or produce a new chemical substance, and (i) the 

manufacturer manufactures or produces the substance exclusively for that person, and (ii) that person specifies the 

identity of the substance, and controls the total amount produced and the basic technology for the plant process, 

that person must submit the notice. If it is unclear who must report, EPA should be contacted to determine who 

must submit the notice. 

(3) Only manufacturers that are incorporated, licensed, or doing business in the United States may submit a 

notice. 

(b)(1) Any person who intends to import a new chemical substance into the United States for commercial 

purposes must submit a notice, unless the substance is excluded under §720.30 or unless the substance is imported 

as part of an article. 

(2) When several persons are involved in an import transaction, the notice must be submitted by the principal 

importer. If no one person fits the principal importer definition in a particular transaction, the importer should 

contact EPA to determine who must submit the notice for that transaction. 

§ 720.25 Determining whether a chemical substance is on the Inventory. 

(a) A new chemical substance is any chemical substance that is not currently listed on the Inventory. 

(b)(1) A chemical substance is listed in the public portion of the Inventory by a specific chemical name (either a 

Chemical Abstracts (CA) Index Name or a CA Preferred Name) and a Chemical Abstracts Service (CAS) 

Registry Number if its identity is not confidential. If its identity is confidential, it is listed in the public portion of 

the Inventory by a TSCA Accession Number and a generic chemical name that masks the specific substance 

identity. The confidential substance is listed by its specific chemical name only in the confidential portion of the 

Inventory, which is not available to the public. A person who intends to manufacture or import a chemical 

substance not listed by specific chemical name in the public portion of the Inventory may ask EPA whether the 

substance is included in the confidential Inventory. EPA will answer such an inquiry only if EPA determines that 

the person has a bona fide intent to manufacture or import the chemical substance for commercial purposes. 

(2) To establish a bona fide intent to manufacture or import a chemical substance, the person who proposes to 

manufacture or import the substance must submit to EPA: 

(i) Except as provided in paragraphs (b)(3) (i) and (ii) of this section, the specific chemical identity of the 

substance that the person intends to manufacture or import, using the currently, correct CA name for the substance 

and the other correct chemical identity information in accordance with §§720.45(a) (1), (2), and (3). 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 720

(ii) A signed statement that the person intends to manufacture or import that chemical substance for commercial 

purposes. 

(iii)(A) A brief description of the research and development activities conducted to date related to the substance, 

including the year in which the person first started to conduct research or development activity on the substance, 

and the general types of research and development activities conducted thus far (e.g., synthesis, substance 

isolation/purification, formulating, product development, process development, end-use application, toxicity 

testing, etc.). The person must also indicate whether any pilot plant or production-scale plant evaluations have 

been conducted involving the manufacture or processing of the substance. 

(B) If an importer is unable to provide the information requested in paragraph (b)(2)(iii)(A) of this section from 

the foreign manufacturer or supplier, the following information shall be submitted: 

( 1 ) A brief statement indicating how long the substance has been in commercial use outside of the United States. 

( 2 ) The name of a country in which it has been commercially used. 

( 3 ) Whether the importer believes that the substance has already been used commercially, in any country, for the 

same purpose or application that the importer is intending. 

(iv) A specific description of the major intended application or use of the substance. 

(v) An infrared spectrum of the substance, or alternative spectra or other data which identify the substance if 

infrared analysis is not suitable for the substance or does not yield a reasonable amount of structural information. 

When using alternative spectra or instrumental analysis, the person must submit a spectrum or instrumental 

readout for the substance. 

(vi) The estimated date (month/year) in which the person intends to submit a Premanufacture Notice (PMN) for 

this substance if EPA informs the notice submitter that the substance is not on the Inventory. 

(vii) The address of the facility under the control of the submitter at which the manufacture or processing of the 

substance would most likely occur. For an imported substance, the facility under the control of the importer at 

which processing of the substance would likely occur, if any. 

(viii)(A) For substances intended to be manufactured in the United States, a description of the most probable 

manufacturing process that would be used by the submitter to produce the substance for non-exempt commercial 

purposes. 

(B) For substances intended to be imported, a brief description of how the submitter is most likely to process or 

use the substance for a commercial purpose. If the substance is not expected to be processed or used at any facility 

under the importer's control, a statement to this effect must be included along with a description of how the 

substance will be processed or used at sites controlled by others, if this information is known or reasonably 

ascertainable. 

(3)(i) If an importer cannot provide the chemical identity information required by paragraph (b)(2) (i) and (v) of 

this section because it is claimed confidential by its foreign manufacturer or supplier, the foreign manufacturer or 

supplier must supply the required information directly to EPA in accordance with §720.45(a) (1), (2), and (3) and 

reference the importer's notice. If the appropriate supporting document from the foreign party is not received 

within 30 days after EPA receives the importer's notice, the notice will be considered incomplete. 

(ii) If a manufacturer cannot provide all of the required information in accordance with §720.45(a) (1), (2), and 

(3) because the new chemical substance is manufactured using a reactant that has a specific chemical identity 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 720

claimed as confidential by its supplier, the notice must contain chemical identity information that is as complete 

as known by the manufacturer. In addition, a letter of support for the notice must then be sent to EPA by the 

chemical supplier of the confidential reactant, providing the specific chemical identity of the proprietary reactant. 

The letter of support must reference the manufacturer's notice. If the appropriate supporting document from the 

supplier is not received within 30 days after EPA receives the manufacturer's notice, the notice will be considered 

incomplete. 

(4) EPA will review the information submitted by the proposed manufacturer or importer under this paragraph to 

determine whether it has a bona fide intent to manufacture or import the chemical substance. If necessary, EPA 

will compare this information either to the information requested for the confidential chemical substance under 

§710.7(e)(2)(v)ofthischapterorthe information requested under §720.85(b)(3)(iii). 

(5) If the proposed manufacturer or importer has shown a bona fide intent to manufacture or import the substance, 

and provide sufficient unambiguous chemical identity information so EPA can make a conclusive determination 

of the chemical substance's Inventory status, EPA will search the confidential Inventory and inform the proposed 

manufacturer or importer whether the chemical substance is on the confidential Inventory. 

(6) If the chemical substance is found on the confidential Inventory, EPA will notify the person(s) who originally 

reported the chemical substance that another person has demonstrated a bona fide intent to manufacture or import 

the substance and therefore was told that the chemical substance is on the Inventory. 

(7) A disclosure of a confidential chemical identity to a person with a bona fide intent to manufacture or import 

the particular chemical substance will not be considered a public disclosure of confidential business information 

under section 14 of the Act. 

(8) EPA will answer an inquiry on whether a particular chemical substance is on the confidential Inventory within 

30 days after receipt of a complete submission under paragraph (b)(2) of this section. 

(9) If the required chemical identity information has not been reported correctly or completely in the notice 

(except as provided under paragraph (b)(3)(ii) of this section) or if any other required data or information has been 

omitted or is incomplete, EPA will consider the whole notice to be incomplete. As soon as an incomplete notice is 

identified as such by EPA, the Agency will immediately return the notice directly to the submitter. The submitter 

must then resubmit the whole, completed bona fide notice to EPA in order to have the Agency perform the 

desired Inventory search and respond to the notice.

§ 720.36 Exemption for research and development. 

(a) This part does not apply to a chemical substance if the following conditions are met: 

(1) The chemical substance is manufactured or imported only in small quantities solely for research and 

development. 

(2) The manufacturer or importer notifies all persons in its employ or to whom it directly distributes the chemical 

substance, who are engaged in experimentation, research, or analysis on the chemical substance, including the 

manufacture, processing, use, transport, storage, and disposal of the substance associated with research and 

development activities, of any risk to health, identified under paragraph (b) of this section, which may be 

associated with the substance. The notification must be made in accordance with paragraph (c) of this section. 

(3) The chemical substance is used by, or directly under the supervision of, a technically qualified individual. 

(b)(1) To determine whether notification under paragraph (a)(2) of this section is required, the manufacturer or 

importer must review and evaluate the following information to determine whether there is reason to believe there 

is any potential risk to health which may be associated with the chemical substance: 

(i) Information in its possession or control concerning any significant adverse reaction by persons exposed to the 

chemical substance which may reasonably be associated with such exposure. 

(ii) Information provided to the manufacturer or importer by a supplier or any other person concerning a health 

risk believed to be associated with the substance. 

(iii) Health and environmental effects data in its possession or control concerning the substance. 

(iv) Information on health effects which accompanies any EPA rule or order issued under sections 4, 5, or 6 of the 

Act that applies to the substance and of which the manufacturer or importer has knowledge. 

(2) When the research and development activity is conducted solely in a laboratory and exposure to the chemical 

substance is controlled through the implementation of prudent laboratory practices for handling chemical 

substances of unknown toxicity, and any distribution, except for purposes of disposal, is to other such laboratories 

for further research and development activity, the information specified in paragraph (b)(1) of this section need 

not be reviewed and evaluated. (For purposes of this paragraph, a laboratory is a contained research facility where 

relatively small quantities of chemical substances are used on a non-production basis, and where activities involve 

the use of containers for reactions, transfers, and other handling of substances designed to be easily manipulated 

by a single individual.)

§ 720.85 Chemical identity. 

(a) Claims applicable to the period prior to commencement of manufacture or import. (1)(i) A person who 

submits information to EPA under this part may assert a claim of confidentiality for the chemical identity of the 

new chemical substance. This claim will apply only to the period prior to the commencement of manufacture or 

import for commercial purposes. A submitter may assert this claim only if the submitter believes that public 

disclosure prior to commencement of manufacture or import of the fact that anyone intends to manufacture or 

import the specific chemical substance for commercial purposes would reveal confidential business information. 

(ii) If the notice includes a health and safety study concerning the new chemical substance and if the claim for 

confidentiality with respect to the chemical identity is denied in accordance with §720.90(c), EPA will deny a 

claim asserted under this paragraph.

that none is adequate and further consultation is necessary. 

(4) If a submitter claims chemical identity to be confidential under this paragraph, and if the submitter complies 

with paragraph (a)(2) of this section, EPA will issue for publication in the Federal Register notice described in 

§720.70 the generic name proposed by the submitter or one agreed upon by EPA and the submitter. 

(b) Claims applicable to the period after commencement of manufacture or import. (1) Any claim of 

confidentiality under paragraph (a) of this section is applicable only until the substance is manufactured or 

imported for commercial purposes and becomes eligible for inclusion on the Inventory. To maintain the 

confidential status of the chemical identity when the substance is added to the Inventory, a submitter must reassert 

the confidentiality claim and substantiate the claim in the notice of commencement of manufacture required under 

§720.102. A submitter may not claim the chemical indentity confidential for the period after commencement of

confidentiality with respect to the chemical identity is denied in accordance with §720.90(c), EPA will deny a 

claim asserted under this paragraph. 

(3) Any person who asserts a confidentiality claim for chemical identity must: 

(i) Comply with the requirements of paragraph (a)(3) of this section regarding submission of a generic name. 

(ii) Agree that EPA may disclose to a person with a bona fide intent to manufacture or import the chemical 

substance the fact that the particular chemical substance is included on the confidential Inventory for purposes of 

notification under section 5(a)(1)(A) of the Act. 

(iii) Have available for the particular chemical substance, and agree to furnish to EPA upon request: 

(A) An elemental analysis. 

(B) Either an X-ray diffraction pattern (for inorganic substances), a mass spectrum (for most other substances), or 

an infrared spectrum of the particular chemical substance, or if such data do not resolve uncertainties with respect 

to the identity of the chemical substance, additional or alternative spectra or other data to identify the chemical 

substance.

(iv) Provide a detailed written substantiation of the claim, by answering the following questions: 

(A) What harmful effects to your competitive position, if any, do you think would result if EPA publishes on the 

Inventory the identity of the chemical substance? How could a competitor use such information given the fact that 

the identity of the substance otherwise would appear on the Inventory of chemical substances with no link 

between the substance and your company or industry? How substantial would the harmful effects of disclosure 

be? What is the casual relationship between the disclosure and the harmful effects? 

(B) For what period of time should confidential treatment be given? Until a specific date, the occurrence of a 

specific event, or permanently? Why? 

(C) Has the chemical substance been patented? If so, have you granted licenses to others with respect to the patent 

as it applies to the chemical substance? If the chemical substance has been patented and therefore disclosed 

through the patent, why should it be treated as confidential for purposes of the Inventory? 

(D) Has the identity of the chemical substance been kept confidential to the extent that your competitors do not 

know it is being manufactured on imported for a commercial purpose by anyone? 

(E) Is the fact that someone is manufacturing or importing this chemical substance for commercial purposes 

available to the public, e.g., in technical journals or other publications; in libraries; or in State, local, or Federal 

agency public files? 

(F) What measures have you taken to prevent undesired disclosure of the fact that you are manufacturing or 

importing this substance for a commercial purpose? 

(G) To what extent has the fact that you are manufacturing or importing this chemical substance for a commercial 

purpose been disclosed to others? What precautions have you taken in regard to these disclosures? Has this 

information been disclosed to the public or to competitors? 

(H) In what form does this particular chemical substance leave the site of manufacture, e.g., as part of a product; 

in an effluent or emission stream? If so, what measures have you taken to guard against discovery of its identity? 

(I) If the chemical substance leaves the site of manufacture in a product that is available to either the public or 

your competitors, can they identify the substance by analyzing the product? 

(J) For what purpose do you manufacture or import the substance? 

(K) Has EPA, another Federal agency, or any Federal court made any pertinent confidentiality determinations 

regarding this chemical substance? If so, copies of such determinations must be included in the substantiation. 

(L) If the notice includes a health and safety study concerning the new chemical substance, the submitter must 

also answer the questions in §720.90(b)(2). 

(4) If the submitter does not meet the requirements of this paragraph, EPA will deny the claim of confidentiality. 

(5)(i) EPA will publish a generic name on the public Inventory if: 

(A) The submitter asserts a claim of confidentiality in accordance with this paragraph. 

(B) No claim for confidentiality of the specific chemical identity as part of a health and safety study has been 

denied in accordance with part 2 of this title or §720.90.

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 720

(ii) Publication of a generic name on the public Inventory does not create a category for purposes of the Inventory. 

Any person who has a bona fide intent to manufacture or import a chemical substance which is described by a 

generic name on the public Inventory may submit an inquiry to EPA under §720.25(b) to determine whether the 

particular chemical substance is included on the confidential Inventory. 

(iii) Upon receipt of a request described in §720.25(b), EPA may require the submitter which originally asserted 

confidentiality for a chemical substance to submit to EPA the information listed in paragraph (b)(3)(iii) of this 

section. 

(iv) Failure to submit any of the information required under paragraph (b)(3)(iii) of this section within ten days of 

a request by EPA under this paragraph is a waiver of the original submitter's confidentiality claim. In this event, 

EPA may place the specific chemical identity on the public Inventory without further notice to the original 

submitter. 

(6) If a submitter asserts a claim of confidentiality under this paragraph, EPA will examine the generic chemical 

name proposed by the submitter. 

(i) If EPA determines that the generic name proposed by the submitter is only as generic as necessary to protect 

the confidential identity of the particular chemical substance, EPA will place that generic name on the public 

Inventory. 

(ii) If EPA determines that the generic name proposed by the submitter is more generic than necessary to protect 

the confidential identity, EPA will propose in writing, for review by the submitter, an alternative generic name 

that will reveal the chemical identity of the chemical substance to the maximum extent possible. 

(iii) If the generic name proposed by EPA is acceptable to the submitter, EPA will place that generic name on the 

public Inventory. 

(iv) If the generic name proposed by EPA is not acceptable to the submitter, the submitter must explain in detail 

why disclosure of that generic name would reveal confidential business information and propose another generic 

name which is only as generic as necessary to protect the confidential identity. If EPA does not receive a response 

from the submitter within 30 days after the submitter receives the proposed name, EPA will place EPA's chosen 

generic name on the public Inventory. If the submitter does provide the information requested, EPA will review 

the response. If the submitter's proposed generic name is acceptable, EPA will publish that generic name on the 

public Inventory. If the submitter's proposed generic name is not acceptable, EPA will notify the submitter of 

EPA's choice of a generic name. Thirty days after this notification, EPA will place the chosen generic name on the 

public Inventory. 

§ 720.87 Categories or proposed categories of uses of a new chemical substance. 

(a) A person who submits information to EPA under this part on the categories or proposed categories of use of a 

new chemical substance may assert a claim of confidentiality for this information. 

(b) A submitter that asserts such a claim must: 

(1) Report the categories or proposed categories of use of the chemical substance. 

(2) Provide, in nonconfidential form, a description of the uses that is only as generic as necessary to protect the 

confidential business information. The generic use description will be included in the Federal Register notice 

described in §720.70.

such as the name of the submitting company, cost or other financial data, product development or marketing 

plans, and advertising plans, for which the person submits a claim of confidentiality in accordance with §720.80. 

(b) Specific chemical identity —(1) Claims applicable to period prior to commencement of manufacture. A claim 

of confidentiality for the period prior to commencement of manufacture or import for the chemical identity of a 

chemical substance for which a health and safety study was submitted must be asserted in conjunction with a 

claim asserted under §720.85(a). 

(2) Claims applicable to period after commencement of manufacture or import for commercial purposes. To 

maintain the confidential status of the chemical identity of a chemical substance for which a health and safety 

study was submitted after commencement of manufacture or import, the claim must be reasserted and 

substantiated in conjunction with a claim under §720.85(b). In addition to the questions set forth in 

§720.85(b)(3)(iv) of this part, the submitter must answer the following questions: 

(i) Would disclosure of the chemical identity disclose processes used in the manufacture or processing of a 

chemical substance or mixture? Describe how this would occur. In responding to the question in 

§720.85(b)(3)(iv)(A), explain what harmful competitive effects would occur from disclosure of this process 

information. 

(ii) Would disclosure of the chemical identity disclose the portion of a mixture comprised by any of the 

substances in the mixture? Describe how this would occur. In responding to the question in §720.85(b)(3)(iv)(A), 

explain what harmful competitive effects would occur from disclosure of this information. 

(iii) Do you assert that disclosure of the chemical identity is not necessary to interpret any of the health and safety 

studies you have submitted? If so, explain how a less specific identity would be sufficient to interpret the studies. 

(c) Denial of confidentiality claim. EPA will deny a claim of confidentiality for chemical identity under paragraph 

(b) of this section, unless: 

(1) The information would disclose processes used in the manufacture or processing of a chemical substance or 

mixture. 

(2) In the case of a mixture, the information would disclose the portion of the mixture comprised by any of the 

substances in the mixture. 

(3) The specific chemical identity is not necessary to interpret a health and safety study.
