This manual is designed to give applicants and registrants to the OMRI Canada Review Program the information neces-sary to know whether a product would be compliant if it were submitted as an application to OMRI. It describes the OMRI’s standards for input product compliance with the Canadian Organic Regime (COR) which encompasses the Canada Or-ganic Standards (COS). The COR is a government system for regulating organic agricultural products. The Canadian Food Inspection Agency (CFIA) is responsible for the monitoring and enforcement of the regulations. Under the Regime, Cer-tification Bodies are accredited by CFIA based on the recom-mendation of CFIA designated Conformity Verification Bod-ies. The Certification Bodies are responsible for verifying the application of the Canadian Organic Standards.

The COS form the foundation of the OMRI Canada Review Program standards. The COS are the regulatory text admin-istered by the CFIA’s Canada Organic Office found at CAN/CGSB 32.310 and 32.311. The OMRI Permitted Substances

Categories are based on the Permitted Substances List (PSL) of the COS, and serve as a resource for applicants who wish to have their product listed by OMRI. OMRI may review prod-ucts against additional standards that are provided in more de-tail on the OMRI website and in OMRI’s application materials. In addition to COS and the OMRI Canada Standards Manu-al©, OMRI maintains an Administrative Procedures Manual that describes review procedures in greater detail. The Admin-istrative Procedures Manual is available upon request.

OMRI standards are updated as necessary to reflect chang-es to applicable federal laws or regulations. Check the OMRI web page, www.omri.org, to be sure you have the most current OMRI standards.

This manual outlines specific criteria used along with the COS to evaluate products for listing in the OMRI Products List©. Additional requirements for application to the OMRI Review Program are described in the OMRI Policy Manual©, on OMRI’s website, and in the application materials.

Part 1: About the OMRI Standards for Compliance with the Canada Organic Standards

Part 2: General Review Standards 2.1 Synthetic versus Nonsynthetic Determination

CAN/CGSB 32.310 and CAN CGSB 32.311 reference the use of nonsynthetic and synthetic materials in organic produc-tion. Primarily, if substances appear in the PSL, they are al-lowed for use in accordance with source and use restrictions. In some cases, the PSL stipulates that only nonsynthetic forms of the substance may be used; or that the synthetic form can only be used if the nonsynthetic form is commercially unavailable. OMRI uses the definition of ‘synthetic substance’ as it appears

in the CAN/CGSB 32.310 Par. 3 (Definitions and Terminol-ogy) – “A man-made substance formulated or manufactured by a chemical process or by a process that chemically alters com-pounds extracted from plant, micro-organisms, and animal or mineral sources. This term does not apply to compounds syn-thesized or produced by biological processes, including heat and mechanical processing.” OMRI also may use the Canada Organic Office Standards Interpretation Committee’s (SIC) Question and Answers when determining synthetic and non-synthetic classifications.

15CanStanMan-pub-version1F 3

Except for those substances appearing in the PSL, OMRI does not permit products that contain a substance prohibited by Paragraph 1.4.1. of CAN/CGSB 32.310 as follows:

3.1 Genetic Engineering Materials and products produced from genetic engineering

are not permitted under this standard, except for vaccines only that have been grown on genetically engineered substrates but are not themselves a product of genetic engineering, as speci-fied in CAN/CGSB-32.311, Organic Production Systems – Permitted Substances Lists. Genetic engineering refers to tech-niques by which the genetic material of an organism is changed in a way that does not occur naturally by multiplication and/or natural recombination. Some examples of these techniques include recombinant DNA techniques that use vector systems and cell fusion with cells that do not fall within the same taxo-nomic family. Except for specific exemptions to this clause, OMRI does not permit genetically engineered ingredients or products of genetically engineered substances in products for use according to the COS.

3.2 Synthetic PesticidesSynthetic pesticides (e.g., defoliants and desiccants, fungi-

cides, insecticides and rodenticides), wood preservatives (e.g., arsenate) or other pesticides, except as specified in CAN/CGSB-32.311, Organic Production Systems - Permitted Sub-stances Lists, are not permitted.

3.3 Sewage SludgeSewage sludge, in any form, as defined in the standard, is pro-

hibited as an ingredient and OMRI will not permit it in prod-ucts.

3.4 Synthetic Growth RegulatorsSynthetic growth regulators are not permitted by the stan-

dard, and OMRI will not allow them as ingredients in products.

3.5 Synthetic Allopathic Veterinary Drugs

Synthetic allopathic drugs, including antibiotics and parasti-cides are prohibited, except for those specified in the standard. OMRI does not permit these ingredients in products.

3.6 Synthetic Processing SubstancesSynthetic processing substances, aids and ingredients, and

food additives and processing including sulfates, nitrates and nitrites, except as specified in the PSL are prohibited as ingre-dients in products.

3.7 Ionizing RadiationIonizing radiation and forms of irradiation on products des-

tined for food or their inputs, as defined in this standard, ex-cept as specified in the PSL, is prohibited. Ionizing radiation is a sanitation or preservative method for packaged or bulk food-stuffs that controls insect infestation and that reduces micro-bial load by ionizing radiation from Cobalt-60 or Cesium-137; or X-rays generated by a machine source operated at or below an energy level of 5 MeV; or from electrons generated by a ma-chine source operated at or below an energy level of 10 MeV. OMRI does not permit the use of ionizing radiation on any ingredients or products except for those exempted in the PSL.

3.8 Packaging and Containers with Prohibited Substances

Equipment, packaging materials and storage containers, or bins that contain a synthetic fungicide, preservative or fumi-gant are prohibited.

3.9 NanotechnologyNanotechnology, as defined by the standard, is prohibited.

Nanotechnology refers to intentionally manufactured nano-technology products, or nano-processes involving intentional manipulation of matter at the nano scale to achieve new prop-erties or functions that are different than properties and func-tions of the materials at the macro scale, except naturally oc-

Part 3: Prohibited Substances, Methods, or Ingredients in Organic Production and Handling (CAN/CGSB 32.310 Paragraph 1.4.1)


curring nano sized particles, or those produced incidentally through normal processes such as grinding flour, or nano sized particles used in a way that guarantees no transference to prod-uct. OMRI does not permit the use of nanotechnology in in-gredients or products.

Part 4: Additional OMRI StandardsIn addition to the Canadian Organic Standards (COS),

OMRI reviews products to additional standards that are iden-tified on OMRI’s website at www.omri.org. These additional standards include OMRI’s interpretation of the COS to ensure product compliance.

4.1 Additional Standards for Crop Fertilizers and Soil Amendments

Certain substances appearing in the PSL may use synthetic substances as extractants, but OMRI does not allow extractants to be used in greater quantities than are necessary for extrac-tion. OMRI has developed thresholds for these substances used in crop production, and products that exceed these thresholds and that may be fortified with plant nutrients such as nitrogen, phosphorous, and/or potassium will be prohibited.

CAN/CGSB 32.311 requires that “Composting feedstocks that may be contaminated with substances not included or prohibited by par. 1.4.1 of CAN/CGSB 32.310 shall require documentation to confirm the absence of these substances…” Operators may have the option of analysis of the final product to confirm that no contaminants persist, and OMRI standards for residual contaminants are outlined on OMRI’s website at OMRI.org.

4.2 Additional Standards for PesticidesBoth active and inert, or formulant ingredients in pesticides

must meet the OMRI standards. All pesticides are subject to the restriction in CAN/CGSB 32.310 par. 5.6.2 which requires that pest, disease and weed control be centered on organic management practices aimed at enhancing crop health and reducing losses caused by weeds, disease and pests. Organic management practices include cultural practices (e.g. rotations, establishment of a balanced ecosystem, and use of resistant va-rieties) and mechanical techniques (e.g. sanitation measures, cultivation, traps, mulches and grazing). Formulants must ap-pear on the PSL Table 4.3.

OMRI will not accept an application that simply lists “inert ingredients” as a component. OMRI listing is not a substitute for PMRA or other governmental registration. All pesticide products sold in Canada must be PMRA registered. OMRI will identify products not registered for use in Canada as such in the OMRI Products List.


Part 5: Introduction to OMRI Permitted Substances Categories

The OMRI Permitted Substances Categories include an ex-planation of the permitted uses, standards of identities, and reference to the Permitted Substances List (PSL) for many substances that may be used in a finished input product. These descriptions are provided to assist applicants in choosing the appropriate use categories for potential listing in the OMRI Canada Products List. The OMRI Permitted Substances Cat-egories conform to the COS, and are based on the PSL (CAN/CGSB 32.311).

The PSL is a list of substances that are allowed or prohibited in organic production. It specifies nonsynthetic and synthetic materials that are permitted in crop and livestock production. It also stipulates that certain synthetic or nonsynthetic materi-als are prohibited. Where the Permitted Substances List does not specify different standards for synthetic and nonsynthetic versions of a substance, or where a substance is only available in one form, these categories will indicate “Synthetic/Nonsyn-thetic” in order to encompass all options.

For processing the PSL specifies those nonorganic ingre-dients and processing aids that may be used in ‘organic’ and products whose contents are ‘70% or more and less than 95% organic ingredients’ processed foods. OMRI has also included some categories that describe broad types of products for easi-er categorization. These additional categories are based on the PSL. The OMRI Permitted Substances Categories are divided into three sections: Crop Production Categories, Livestock Production Categories, and Processing and Handling Catego-ries. Categories included in each section are sorted alphabeti-cally and designated with a two-letter OMRI Class code and an OMRI Status that indicates that they are Allowed or Allowed with Restrictions under the COS. OMRI’s Allowed with Re-strictions status indicates use restrictions that are required for compliant use of the material under the COS. Further informa-tion on status is given at the beginning of the Crops, Livestock, and Processing and Handling sections.

Other features of the OMRI Permitted Substances Catego-ries for crops, livestock and processing listings include:

• OMRI Class – groups materials into several distinct end-use classes. OMRI also uses these Class Codes in the OMRI Products List for easy referral to the OMRI Per-mitted Substances Categories.

• OMRI Annotation – details use parameters, and provides additional information and COS Rule specifications for the generic material.

• COS Rule citations – cites applicable regulatory sections for each material listing.

5.1 How to use the OMRI Permitted Substances Categories

Applicants to the OMRI Canada Review Program must choose a category that corresponds to the intended product use. For example, those who produce a product for use as a fertilizer should search within the CROPS section. Or, alterna-tively, those who produce animal health care products should search within the LIVESTOCK section.

It is also important to identify when and how the mate-rial is permitted for use. Note the class or classes for which the product is permitted for use. The class is given as a two-letter code just below the material name. A key to the OMRI class codes appears at the bottom of each even numbered page. List-ed products will only be allowed for use within the specified OMRI class for that material entry.

To stay current with COS changes that may affect a material status and/or a material use, applicants should regularly check the OMRI website (www.omri.org) for standards updates.

5.2 Regulatory ComplianceIn addition to the COS and the OMRI Standards, other na-

tional, federal, state, and local laws and regulations may apply to the use of materials on organic operations. OMRI makes no representation that the materials listed here comply with any of these other requirements. It is the user’s responsibility to determine the compliance of a particular substance with all ap-plicable laws and regulations.


Class CodesCF: Crop Fertilizers and Soil AmendmentsCP: Crop Pest, Weed, and Disease ControlCT: Crop Management Tools and Production Aids

CROPPr o d uc tio n Ca te g o r ie sClass Coding

Crop production materials are classified by OMRI accord-ing to the following Use Classes:

CF: Crop Fertilizers and Soil Amendments CP: Crop Pest, Weed, and Disease ControlCT: Crop Management Tools and Production Aids

Crop Fertilizers and Soil Amendments (CF) are soil amendments and crop nutrition substances which corre-spond to listings in Table 4.2 of the Permitted Substances List (PSL) (CAN/CGSB-32.311, Organic Production Systems – Per-mitted Substances Lists). They are substances applied to the soil to improve fertility and tilth and to correct soil problems. Fertilizers, plant foods and soil amendments are primarily used for their plant nutrient content and may be applied to the soil or to the foliage of plants. Examples include com-post, animal manures, blood/bone meals, plants and plant by-products. Use of fertilizers and soil amendments must comply with requirements of CAN/CGSB-32.310 par 5.4: Soil Fertility and Crop Nutrient Management, and par 5.5: Manure Management. Unless otherwise specified, the soil amend-ments and crop nutrients listed in Table 4.2 of the PSL shall not contain substances prohibited by par. 1.4.1 of CAN/CGSB-32.310, Organic Production Systems – General Principles and Management Standards, or not permitted on the Permitted Substances Lists.

Crop Pest, Weed and Disease Control (CP) substances are those used to control pests (disease, weed or insect), and they correspond to substances listed in Table 4.3 of the PSL. They include vertebrate animal pest management substanc-es, plant disease management substances, insect pest man-agement (invertebrates), mites, molluscs and crustacean substances; and nematode management substances. Plant growth regulators are also considered pest control substanc-es when used to control “any injurious or troublesome organic function of a plant,” and are therefore subject to regulation under the Pest Management Regulatory Agency (PMRA) Pest

Control Products Act. Pest control products shall not contain substances

prohibited by par. 1.4.1 of CAN/CGSB-32.310, Organic Produc-tion Systems – General Principles and Management Stan-dards, or substances that are not permitted by the Permitted Substances List. Biological, botanical, or other pest control substances listed in Table 4.3 of the PSL may be used only when organic management practices and mechanical tech-niques alone cannot prevent or control crop pests, disease or weeds, per CAN/CGSB-32.310 par 5.6.2. The conditions for using such substances must be documented in the organic plan, in accordance with section 4 of CAN/CGSB-32.310. Use of pest control substances must meet the requirements of any limiting annotation specified in Table 4.3 of the PSL.

Crop Management Tools and Production Aids (CT) include inputs used in conjunction with other substances, which may or may not be directly applied to the crop or soil, and which do not provide a recognized plant nutrient, soil conditioning or crop protection function. They are listed in Table 4.3 of the PSL, together with crop pest, weed and disease control substances (CP). Examples of crop management tools and production aids include adjuvants, equipment cleaners, insect traps, compost inoculants, and plant extracts without nutrient or pest control claims. These products shall not contain sub-stances prohibited by par. 1.4.1 of CAN/CGSB-32.310, Organic Production Systems – General Principles and Management Standards, or not permitted on the Permitted Substances Lists.

StatusCrop production substances have one of the following

OMRI Status designations:Allowed (A) crop production substances include those

that appear on Table 4.2 or 4.3 of the PSL with no annotation that limits their use. The OMRI ‘Allowed’ status therefore indi-cates that these materials are not subject to use restrictions beyond the general management requirements in CAN/CGSB-32.310 par. 5.4 and 5.5.

Allowed with Restrictions (R) crop production substanc-es include those that appear on Table 4.2 or 4.3 of the PSL with annotations that limit their use. The OMRI ‘Allowed with
