About OMRI
How do organic farmers know which fertilizers are ok to use? Who ensures that organic foods are made in facilities that follow organic practices and use prescribed sanitizers?
Accredited certifying agents work with organic producers to maintain a list of approved inputs for the operations, and they also rely on OMRI to help them know which products are appropriate for which uses.
OMRI Listed Inputs

Certified Organic Outputs
OMRI reviews and lists the input products, such as fertilizers, pest controls, and livestock care products, that are compliant with organic standards.
Allowed products are "OMRI Listed®" and may display the OMRI seal. A full catalog of OMRI Listed products is available through the website search, or by downloading or purchasing the OMRI Products List©.
OMRI Listed input products are then used to produce organic food and fiber products such as carrots, granola bars and cotton that are certified by an accredited certifying body.
By focusing exclusively on inputs, OMRI provides essential expertise to support the organic certification process.
On average 10-15% of the applications that OMRI receives do not make it through the process, either because the application is withdrawn by the applicant, or the product is determined to be prohibited. This means that some products on the marketplace are advertised or otherwise thought to be compliant, when they actually are not. One way to be sure is to look for the OMRI seal.
Is OMRI a Certifier?
No, OMRI exclusively reviews inputs and does not certify food or fiber products. OMRI is the only independent, nonprofit organization dedicated to input materials used in organic production. OMRI is a trusted third-party accredited to ISO 17065 standards by the USDA Quality Assessment Division. Where certifiers focus on the food and fiber products that you see on the grocery store shelves, OMRI verifies the substances used in organic production: fertilizers, pesticides, livestock health care products, processing aids, and a number of other products that organic farmers and processors rely on every day. OMRI resources support the work of all certifiers to ensure that materials used in organic food production meet the organic standards, in accordance with consistent criteria and review methods.
Accreditation
OMRI is accredited by the USDA Quality Assessment Division under the International Organization for Standardization (ISO) 17065: Conformity assessment – requirements for bodies certifying products, processes and services. Every year, USDA experts assess OMRI procedures to ensure continued conformance with established criteria. The assessment evaluates OMRI’s quality system and process for conducting reviews, including procedures for ensuring impartiality, confidentiality, and independent decision making, as well as adherence to the published organic standards and staff qualifications to do this work. You can always find OMRI’s current ISO 17065 certificate at OMRI.org/ISOcertificate.
Under the U.S. National Organic Program standards, input review is governed by NOP 3012: Material Review – Interim Instruction. In accordance with these instructions, input decisions by ISO 17065 accredited Material Review Organizations like OMRI may be used by certifiers to determine acceptable products for organic operations. Similarly, the Canada Organic Regime Operating Manual section C.2.2.5 specifies that certification bodies may accept decisions from third parties that are accredited to ISO 17065.
Mission
OMRI's mission is to cultivate organic integrity through knowledge and trust.
We achieve this by:
- Supporting certifiers with reliable expertise and a comprehensive knowledge hub for input material compliance.
- Providing input manufacturers with thorough, transparent product reviews, and maintaining a publicly accessible and up-to-date list of allowed products.
- Offering farmers and processors a dependable resource for approved inputs, expediting their path to market.
- Assuring consumers with a recognizable seal that signifies compliance with organic standards.
- Collaborating with regulatory bodies to share insights and exchange expertise that informs policy.
OMRI's Vision
At OMRI, we envision a future where communities value what goes into the soil as much as what goes on the table, and where people and the environment can thrive for generations to come.
OMRI's Values

Evolve & Innovate: We push ourselves to grow, improve, and innovate, leveraging expertise and technology to stay relevant and effective in a changing world.

Inclusion, Diversity, Equity and Accessibility Policy and Vision
Approved by the OMRI Board of Directors, August 21, 2024.
OMRI is committed to an antiracist and anti-white supremacist work place. Fostering, cultivating and preserving a culture of diversity, equity and inclusion is an organizational priority, and we are committed to maintaining a safe and brave environment where all have a voice and are welcomed and supported.
We embrace and encourage our differences in ethnicity, race, color, age, disability, family or marital status, gender identity or expression, language, national origin, physical and mental ability, religion, sexual orientation, socio-economic status, veteran status, genetics and other characteristics that make us unique.
The collective sum of these individual differences, life experiences, knowledge, inventiveness, innovation, self-expression, unique capabilities and talent that we invest in our work represents a significant part of not only our culture, but our reputation and the organization’s achievements. Furthermore, OMRI explicitly acknowledges the lived experiences of Black, Indigenous, and People of Color (BIPOC) under systemic and structural oppression, and seeks to elevate their voices throughout the organization.
Our Inclusion, Diversity, Equity and Accessibility Vision and Policy guide our Board of Directors, management, employees, contractors and partners in developing an inclusive culture. OMRI IDEA initiatives are applicable—but not limited—to our practices and policies on recruitment and selection; compensation and benefits; professional development and training; promotions; social and recreational programs; layoffs; and terminations. This policy promotes the ongoing development of a work culture built on the premise of IDEA that encourages and reinforces:
- Recognizing our own implicit biases and the racist world we inhabit, and a commitment to an actively antiracist organization.
- An environment free from bullying, harassment and discrimination where all feel empowered to speak out against instances of prejudice.
- Open, transparent and respectful communication and cooperation between all personnel, customers and others.
- Teamwork and participation, promoting the representation of all groups and individual perspectives throughout all levels of the organization.
- Work/life balance through flexible work schedules to accommodate employees’ varying needs and circumstances, taking current events and lived experiences into consideration.
- OMRI and personnel efforts and contributions to the many communities OMRI serves to promote a greater understanding and respect for the diversity of those communities and a better response to, and representation of those communities.
- Sensitivity toward and accommodation of differing cultures, backgrounds, views, values, beliefs, and styles of learning.
- A commitment to honest self-reflection, constructive feedback, difficult conversations, constant growth, learning, and accountability among peers.
OMRI has a zero tolerance policy for oppressive, racist or otherwise prejudiced behavior. All personnel, e.g., board members, employees, Review Panel members, Advisory Council members, and contractors of OMRI are expected to adhere to this policy, and to treat others with dignity and respect at all times. In addition, suppliers and other customers who exhibit inappropriate contact in the form of prejudiced behavior may be refused services as outlined in the OMRI Policy Manual and Administrative Procedures Manual. Employees who believe they have been subjected to any kind of discrimination that conflicts with OMRI’s diversity policy and initiatives should follow the process for complaints outlined in this manual.
All personnel are expected to exhibit conduct that reflects inclusion during work, at work functions on or off the work site, and at all other organization-sponsored and participative events. Any personnel found to have exhibited any inappropriate conduct or behavior against others will be subject to appropriate discipline up to and including termination. All employees are also required to attend and complete regular IDEA trainings to enhance their knowledge to fulfill this responsibility.
History
OMRI was founded in 1997 to evaluate materials for use in organic agriculture. At that time, there were more than 40 certifiers who were performing organic certification using various state and private standards.
Following passage of the Organic Foods Production Act in 1990, inputs were initially evaluated under a program developed by California Certified Organic Farmers (CCOF), in cooperation with Oregon Tilth Certified Organic (OTCO), the Organic Trade Association (OTA) and the Organic Crop Improvement Association (OCIA). These groups viewed the development of a single resource specializing in input review and materials evaluation as an important step towards implementing a uniform standard. The Northeast Organic Farmers Association of New Jersey and Florida Organic Growers were among the first certifiers to become subscribers to OMRI.
OMRI began operation in June 1997 with financial backing from CCOF, OTCO, OCIA, OTA, the Organic Farming Research Foundation (OFRF), the Association for Regional Agriculture Building Local Economy, Newman’s Own Organics, Whole Foods Market, Smuckers Quality Beverages, and the Humane Society of the United States, as well as many smaller donors.
OMRI used recommendations from an Advisory Council of subject matter experts in organic farming, industry, academia, and the public arena to publish the first OMRI Generic Materials List© in 1998. Once the standards and policies had been established, OMRI began accepting applications to review products. OMRI reviewed the first OMRI Listed® products, and the first OMRI Products List© (formerly known as the OMRI Brand Name Products List) was published in March 1998.
The National Organic Standards (NOS) were published in 2000 in the Federal Register at 7 CFR part 205 and were implemented in October 2002. Today, the NOS and the COR standards for Canada form the basis of OMRI's input reviews.
OMRI produced Technical Advisory Panel (TAP) reports for the National Organic Standards Board (NOSB) from 1999 until 2002. In 2008, OMRI received ISO 65 accreditation from the USDA, and the National Organic Program (NOP) officially permitted certifiers to contract with OMRI for material review. In 2010 the OMRI Products List reached 2,000 products listed for use in organic production, handling and processing. From the beginning, OMRI has been a contractor producing Technical Reports (formerly TAP reports) for the NOSB. OMRI launched the OMRI Canada program in 2013 to provide review of products for use under Canadian Organic Standards.
Here at OMRI, we focus on human beings. The humans we work and laugh with each day. The humans we serve through our review program. The humans who support and rely on the organic system, where we are so proud to serve a critical role. People are at the heart of everything OMRI does, and we’re always looking to find the people whose skills, values and attitudes align with OMRI’s mission and culture. In turn, we strive to maintain a culture and benefits that will support staff in all areas of their lives.
At OMRI, life/work balance is more than a buzzword, because happy humans are a joy to work with. Our staff appreciates generous paid time-off benefits and flexible forty-hour workweeks that really are forty hours. Everyone arrives at OMRI with their unique talents and experiences, and we strive to help our colleagues cultivate new skills and explore new roles whenever possible. These opportunities, along with a casual, candid and supportive workplace culture, contribute to our outstanding track record of staff retention. Check out what some of the team have to say about OMRI!
What are our staff saying?
“OMRI is a perfect fit for me. I get to work for a nonprofit in a sector I really believe in, for a growing company with excellent job security. As a bonus, I truly love the people I work with—there is literally no one I wouldn’t be excited to chat with while waiting for the coffee to finish brewing. Also, covered bike parking!”
“My favorite thing about working [for OMRI] is feeling like my time and my personal life are respected. There’s no expectation that people have to work above and beyond a forty-hour week in order to prove themselves, and I’m always able to log off right at four-thirty and get home to walk my dogs. There is a genuine ‘work-to-live, not live-to-work’ philosophy here.”
“Because OMRI is a nonprofit, it maybe can’t offer eye-popping private-sector salaries, but for me, the value I get from the 100% employer-paid healthcare, the ability to work remotely, and the generous [paid time-off] package more than makes up for it. Plus it feels good to know that the work I’m doing at OMRI is benefiting organics—for me personally, you can’t put a price on that aspect of the job.”

OMRI is governed by a Board of Directors, which is broadly representative of the organic industry. Board members represent certifiers, farmers, input suppliers, processors, handlers, and consumer organizations or public interest groups. The OMRI Advisory Council is composed of independent, professional experts from industry, academia, and the organic community. The Advisory Council makes policies and standards recommendations to the Board of Directors. OMRI Review Panels make the final decision as to whether a product should be OMRI Listed. Four external Review Panels make decisions for Crops, Livestock, Processing and Handling, and for all products reviewed under Canada Organic Regime (COR) standards. OMRI also maintains an internal Review Panel made up of qualified staff.
Board of Directors
The OMRI Board of Directors broadly represents the constituencies of the organic industry, with members selected from the community of certifiers, farmers, suppliers, processors and handlers, and organizations serving consumer and environmental interests. The board is the highest governing body at OMRI. It determines OMRI policy and standards, and plays an active part in guiding OMRI in its public service role and in carrying out its mission. The OMRI Board rarely looks at or discusses individual products. While board members may have vested interests in OMRI Listed suppliers, applicants, or potential applicants, board members recuse themselves from discussions and decisions related to products or companies where a conflict exists.

External Review Panels
OMRI's External Review Panels consist of individuals selected by the Board of Directors to provide expertise in the review of commercial products used in organic crop, livestock and processing operations. OMRI also maintains an Internal Review Panel of qualified staff members that make final status decisions under specific circumstances. All Review Panels make final decisions for newly applying products and selected products that undergo re-review. The Review Panels also consider certain decision rebuttals as outlined in the OMRI Policy Manual©.

Please note that representatives from companies participating in the OMRI Review Program should not contact any member of a review panel regarding any product decision.
Advisory Council
Advisory Council (AC) members are selected by the Board of Directors to provide a broad range of expertise and perspectives from throughout the organic community. AC members include farmers, researchers, professional consultants, industry representatives, and others from within the organic community. The AC helps OMRI Staff and Review Panels interpret OMRI policy and standards and makes recommendations to the Board regarding policy and standards development and refinement. AC members may also participate in research and education projects. The Technical Director serves as staff liaison and coordinator to the Advisory Council.
