The National List of Allowed and Prohibited Substances identifies synthetic substances that may be used and the nonsynthetic (natural) substances that may not be used in organic crop and livestock production. It also lists the non-organic substances that may be used in or on processed organic products. Any individual or organization may submit a petition to add, remove, or amend the listing of a substance.
Role of the NOSB
The National Organic Standards Board (NOSB), a Federal Advisory Committee, reviews petitions based on specific criteria in the Organic Foods Production Act of 1990. Depending on the proposed use of the substance, the petition will be reviewed by an NOSB subcommittee: crops, livestock, or handling.
Role of the NOP
The National Organic Program (NOP) accepts petitions, solicits public comments, and manages all communication with petitioners.
Petition Process
The petition process is summarized below:
- Individual or organization develops & submits petition. A complete petition for a single, generic substance must be submitted to the NOP as described below in the National List Petition Guidelines.
- NOP determines if a substance is eligible for petition. If the substance is eligible for petition and the petition meets the guidelines referenced above, it is forwarded to the appropriate NOSB subcommittee (crops, livestock, or handling). If the petition is insufficient, needs additional information, or requires extensive revisions to comply with Section 508 (section508.gov), NOP contacts the petitioner with further guidelines on what is needed. For web accessibility issues, petitioners have the option to remediate the petition themselves or hire external remediation services to make the file accessible. Once remediated, eligible petitions are posted on the NOP website for public viewing.
- NOSB subcommittee determines if additional information is needed. If the subcommittee finds the petition insufficient, NOP will contact the petitioner to obtain additional information. If the petition is deemed sufficient, the subcommittee may request a technical report. These reports are created by a third-party contractor and posted on the NOP website.
- NOSB subcommittee reviews petition and publishes a proposal with request for public comments. NOSB analyzes comments, subcommittee makes necessary edits based on public comments, and presents the subcommittee proposal to the full NOSB. The NOSB discusses and votes on the proposal during their biannual public meetings.
- NOSB submits final recommendation to NOP. After the meeting, the NOSB finalizes its recommendation to reflect the vote and submits it to the NOP.
- NOP reviews recommendation and initiates rulemaking, if appropriate. The NOP reviews all NOSB recommendations, publishes its response on the NOP website, and initiates rulemaking to implement recommendations (as appropriate). While the NOP may decide not to add a recommended substance to the National List, the NOP cannot add a substance without the NOSB’s recommendation [per the Organic Foods Production Act of 1990, as amended (7 U.S.C. chapter 94) (OFPA)].

National List Petition Guidelines
1. Purpose and Scope
This procedure provides guidelines on submitting a petition to amend the National List of Allowed and Prohibited Substances (National List) at 7 CFR §§ 205.600-205.606. These guidelines, developed in collaboration with the National Organic Standards Board (NOSB), and based on the NOSB’s April 2014 recommendations (see References section below), describe the information to be included in all types of petitions submitted to amend the National List.
The information on this webpage supersedes the Federal Register Notices “Submission of Petitions of Substances for Inclusion on or Removal From the National List of Substances Allowed and Prohibited in Organic Production and Handling,” (72 FR 2167, January 18, 2007), and “National Organic Program; Notice of Availability of National List Petition Guidelines” (81 FR 12680, March 10, 2016) which are now obsolete.
2. Background
The Organic Foods Production Act of 1990, as amended (7 U.S.C. chapter 94) (OFPA), authorizes the establishment of the U.S. Department of Agriculture (USDA) organic regulations, including the National List. The National List identifies the synthetic substances that may be used and the nonsynthetic substances that may not be used in organic production, and also identifies synthetic and nonsynthetic substances that may be used in organic handling. The OFPA and USDA organic regulations specifically prohibit the use of any synthetic substance for organic production and handling unless the synthetic substance is on the National List (see 7 CFR 205.105.) Section 205.105 of the regulations also requires that any nonorganic, nonsynthetic substance used in organic handling be on the National List. The National List can be amended through rulemaking using the petition process or the sunset review process (ams.usda.gov/rules-regulations/organic/nosb/sunset-review). These guidelines apply only to the petition process.
The ability for any person to petition to amend the National List is authorized by § 6518(n) of the OFPA and § 205.607 of the USDA organic regulations. This authorization provides that any person may petition the NOSB to have a substance evaluated by the NOSB for recommendation to the Secretary for inclusion on or removal from the National List. The NOSB is authorized to review petitions under evaluation criteria specified in § 6518(m) of the OFPA, and forward recommendations for amending the National List to the Secretary.
3. Policy
3.1 Who can submit a petition?
Any person may submit a petition to have a substance evaluated by the NOSB (7 CFR 205.607).
3.2 What can be petitioned?
Generic substances are eligible for petition; formulated (brand name) products are not eligible.
3.3 What is the National Organic Program’s role?
The NOP accepts petitions, solicits public comments, and manages all communication with petitioners. If the substance is eligible for petition and the petition meets the guidelines referenced in section 4 below, the petition is posted on the NOP’s Petitioned Substances Index () website for review by the NOSB.
The NOP’s acceptance of the petition for NOSB review is an administrative matter and does not reflect a decision by the NOP on the substantive merits of the petition.
3.4 What is the NOSB’s role?
The NOSB, a Federal Advisory Committee, reviews petitions based on specific criteria in the OFPA.
One of the NOSB subcommittees (crops, livestock, or handling) reviews petitions against the criteria in the OFPA. Prior to NOSB public meetings, the NOP publishes the NOSB subcommittee proposals that include the NOSB’s request for public comments.
The NOSB generally meets twice a year at a public meeting to discuss the items on its work agenda, vote on proposals, and make recommendations to the Secretary. A more in-depth description of NOSB activities, their meeting schedule, and agenda can be found on the NOSB website.
3.5 What criteria does the NOSB use to evaluate petitions?
Pursuant to § 6518(m) of the OFPA, when evaluating a petitioned substance for amendment of the National List, the NOSB shall consider:
- The potential of the substance for detrimental chemical interactions with other materials used in organic farming systems;
- The toxicity and mode of action of the substance and of its breakdown products or any contaminants, and their persistence and areas of concentration in the environment;
- The probability of environmental contamination during manufacture, use, misuse or disposal of the substance;
- The effect of the substance on human health;
- The effects of the substance on biological and chemical interactions in the agroecosystem, including the physiological effects of the substance on soil organisms (including the salt index and solubility of the soil), crops, and livestock;
- The alternatives to using the substance in terms of practices or other available materials; and
- Its compatibility with a system of sustainable agriculture.
Synthetic substances petitioned for use in organic processing are evaluated pursuant to additional criteria in 7 C.F.R. § 205.600(b):
- The substance cannot be produced from a natural source and there are no organic substitutes;
- The substance’s manufacture, use, and disposal do not have adverse effects on the environment and are done in a manner compatible with organic handling;
- The nutritional quality of the food is maintained when the substance is used, and the substance itself, or its breakdown products do not have an adverse effect on human health as defined by applicable Federal regulations;
- The substance’s primary use is not as a preservative or to recreate or improve flavors, colors, textures, or nutritive value lost during processing, except where the replacement of nutrients is required by law;
- The substance is listed as generally recognized as safe (GRAS) by the Food and Drug Administration (FDA) when used in accordance with FDA’s good manufacturing practices (GMP) and contains no residues of heavy metals or other contaminants in excess of tolerances set by FDA; and
- The substance is essential for the handling of organically produced agricultural products.
Pursuant to 7 CFR 205.600(c), nonsynthetic substances petitioned for use in organic processing are evaluated against criteria specified in §§ 6517 and 6518 of the OFPA.
3.6 Is there a specific form needed?
No. There is no form that must be submitted with the petition. However, certain information must be included in the petition as described in section 4.2 below.
Petitions that are determined to be complete are posted online for public access. Content posted online on the AMS website must be Section 508 compliant (See section508.gov). As of November 2024, the NOP requires petitioners to remediate their petitions and petition attachments prior to submission. To expedite this process, we encourage you to consider following the steps outlined on the Accessibility Testing for Electronic Documents page of the Section 508.gov website when creating your documents. This page provides “Authoring Guides” for word processing documents, PDFs, presentations, and spreadsheets. Here are a few tips to help you get started:
- Where possible, upgrade to the latest versions of Microsoft Office and Adobe Acrobat.
- When creating a Microsoft Word document, save the file in the most current file format (.docx as of 2024) to preserve accessibility features. Use a descriptive file name and document title.
- Select Ctrl + F1 to reveal the document formatting. Confirm and/or define the appropriate document language.
- Use Microsoft Word heading styles to format your document. Headings help to provide structure for and organize a document. Make sure that the headings shown in the “Navigation” pane mirror the headings shown in the body of your document.
- Use the “Bullets and Numbering” tools to create lists. Do not manually enter symbols or numbers followed by added spaces, tabs and content.
- Use the “Columns” feature on the “Layout” tab to format content into more than one column. Where possible, avoid using tables to format text into multiple columns.
- When using tables to create a desired text layout, use the tab to navigate the table, making sure the content follows the left-to-right, top-to-bottom reading order.
- Create descriptive link names that describe its destination, function, and/or purpose. We discourage using the URL only, unless the key information about the link can be determined from that context.
- Vital information included in the headers, footers, and watermarks must be duplicated in the body of the document, preferably near the beginning of the document or corresponding section.
- When creating data tables, use the built-in table design and table layout features. Avoid merging or splitting cells. Make sure the data table includes a header row. In the table properties, select the option to repeat the table’s header row. Complex tables that use merged or split cells can only be made accessible through PDF remediation.
- Place all images, objects, and text boxes “in line with text” to allow screen readers to access the content. Non-text content placed any other way is not readable.
- Include descriptive “alt text” or caption for all images, charts, shapes and icons. When an image or object is used just for decoration, mark the content as “decorative” in the “alt text” panel.
- Avoid conveying meaningful content only with colors or another visual characterization. Use text descriptions or alternative text to emphasize the meaning of a color or other visual characteristics, such as size, shape, and location.
- Make sure there is adequate contrast between any text and its background.
- Remove form fields and any flashing content.
For detailed information on how to implement the above guidance, refer to the linked Section 508 guidance above. Once the Microsoft Word file is created and an Adobe PDF is generated, your file may need additional remediation. Follow the instructions outlined in the PDF authoring guidelines linked above.
If remediating the document yourself is not an option, your Microsoft Word document has been created with complex formatting, or you have many PDF attachments included with your petition submission, you may need to hire an external remediation service. To locate firms providing this service, conduct a web search on the term “508 Document Remediation Services” or search for a list of approved government contractors at SAM.gov.
3.7 How long does the petition process take?
The petition process can take a year or more, depending on the complexity associated with the petition, amount of public participation, and other projects on the NOSB work agenda. To facilitate NOP review and NOSB consideration of petitions, petitions should provide concise yet comprehensive responses to the required petition information.
The majority of petitions are reviewed by the NOP for eligibility and completion within 30 days of receipt. Petitions are typically reviewed at an NOSB meeting within two years of the determination by NOP that the petition is eligible for NOSB review.
If the NOSB recommends the addition of a petitioned substance to the National List, the NOP will consider the NOSB recommendation for a future rulemaking action. Petitioned substances may not be used in production or handling unless the substance has been added to the National List.
3.8 Is there a cost or fee for submitting a petition?
No. There is no cost or fee for submitting a petition.
3.9 Are petitions available online?
Yes. Complete and eligible petitions are posted for the public to access in the NOP’s Petitioned Substances Index.
3.10 Can I submit confidential business information or a redacted version that can be posted online?
No. Confidential business information is no longer accepted as part of the National List petition process. Petitions to amend the National List involve a public and open evaluation process.
3.11 How do I submit new information if my petition is under review by the NOSB?
Petitioners may update their petitions at any time. Submissions will be posted as an addendum to the petition for public access on the NOP website. If the entire petition is to be replaced, please contact the NOP prior to submission.
3.12 How do I submit comments about a petition that was submitted by another party?
To be notified of public comment opportunities, you can subscribe to the NOP’s email notification service, the “Organic Insider” on the NOP webpage. Written comments on petitions under NOSB review may be submitted via www.regulations.gov during a public comment period that precedes each NOSB meeting. NOSB meetings also offer opportunities for oral public comments. The NOSB’s meeting schedule and agenda can be found on the NOSB webpage.
3.13 How do I withdraw my petition?
Petitions may be withdrawn according to the guidelines in the most current version of the NOSB’s “Policies & Procedures Manual” available on the NOSB webpage.
4.1 Petition Submissions
Petitions should be submitted to the National List Manager in the NOP’s Standards Division.
Petitions may be submitted by email, disk, or hard copy. Electronic submission (by disk or email) is strongly encouraged to facilitate posting of petitions on the NOP website.
