Add or remove materials

Whether an OMRI-approved product, or a new product for OTCO review, start the process of adding a new material by contacting your client service team. Don’t risk jeopardizing your certification. Never use an unapproved material until after OTCO approval is granted.

How do I confirm if a product is approved for addition and/or use?

Start by determining if your product has already been approved for use in organics by either the Organic Materials Review Institute (OMRI) or the Washington State Department of Agriculture (WSDA). Be sure to search for specific product listings, not just generic versions of products — you will need your specific product approved for use.

Always be sure to check that the desired material is approved for your usage — some materials may be approved for use in only one certification scope (e.g., approved for crops but not processing).

Can I immediately use an OMRI- and/or WSDA-approved product?

If your product has been approved for use by OMRI or the WSDA, you are permitted to use the material in accordance with listed restrictions. You’ll need to keep all necessary records such as application amounts and usage, and a copy or a photocopy of the label.

To add the product to your list of approved materials, send the label, manufacturer name, intended use, and name of your certified operation to your client service team.

What information is needed for review for all other products?

To request a non-OMRI, non-WSDA approved material for review, please send the following to your client service team:

  • Brand name (exact) and type of the product (e.g, “2.0” or “granular”)
  • Manufacturer name (exact) and photo of label for additional verification
  • Ingredients (complete list), label panel, or specification sheet
  • Description of use (e.g., fertilizer, pest control)
  • Destination for end use (e.g., crops, livestock)
  • Name of your certified operation

How will I know when a material is approved for use?

OTCO will review and send you a written response of approval or denial. If approved, your material will be added to your MyOTCO approved materials list with any associated restrictions for use. You can see your current list of approved materials in your MyOTCO account under “Inputs.”

How do I remove an old product from my approved materials list?

Removing materials you no longer use allows your inspector to more easily match materials on-site to your list.

You can update your approved materials list by contacting us with your certified operation’s name, the requestor’s name, and a statement for the material to be removed.
