About the consultation
We are seeking comments on the following amended single ingredient feed (SIF) description for polymethylolcarbamide.
Background
The Feeds Regulations, 2024 require a proponent to submit a pre-market application for new feed ingredients or SIFs that have been modified such that they differ from an approved SIF or SIFs that are for a new purpose. We evaluate the information in the application to establish that the SIF is safe, effective and labelled correctly.
Approved SIFs are listed and described in the Canadian Feed Ingredients Table (CFIT), which is incorporated by reference (IBR) into the Feeds Regulations, 2024. Our Incorporation by Reference Policy requires that a consultation be conducted before changes to IBR documents are made. Refer to Documents incorporated by reference under the Feeds Regulations, 2024 for additional information.
Amended SIF description
Our Animal Feed Program (AFP) has identified that an error was made while transferring the SIF description of polymethylolcarbamide from Schedule IV of the Feeds Regulations, 1983 to the CFIT of the Feeds Regulations, 2024.
We identified that the livestock species for which this SIF has been approved for are not correct in the CFIT. This SIF is approved for use in finished pellets for ruminants, meat producing poultry and swine and not only for use in finished pellets for ruminants and meat producing poultry. The correct approved livestock species are found in the definition in Schedule IV of the Feeds Regulations, 1983. When this SIF was added to the CFIT swine was not included in the list of approved livestock species.
In addition, the alternative SIF name "urea-formaldehyde resin" was omitted in the English version of the CFIT due to a transfer error. This error was identified while working on amending the complete list of livestock species, detailed previously.
We intend to amend the existing SIF description for polymethylolcarbamideunder subclass 6.4 (Pelleting aids) of class 6 (Non-nutritive ingredients) in part 2 of the CFIT. The amended description will contain all approved livestock species for which this SIF has been approved for use as a pelleting aid in finished pellets.
The amended description is:
2-604-001 Polymethylolcarbamide (or urea-formaldehyde resin)
is pulverulent spray-dried urea-formaldehyde resin in an urea: formaldehyde molar ratio of 1:1.6 to 1:2. It shall not contain more than 4% free formaldehyde.
This ingredient is approved for use as a pelleting aid in an amount not to exceed 0.3% in the finished pellets for ruminants, meat producing poultry and swine.
It shall be labelled with the following statements:
"This ingredient is approved for use as a pelleting aid in an amount not to exceed 0.3% in the finished pellets for ruminants, meat producing poultry and swine."
"Consult the Compendium of Medicating Ingredient Brochures to determine if this product is compatible with the medicating ingredient being used."

How to participate
We are seeking feedback on the amended description for polymethylolcarbamide.
Stakeholders are encouraged to share comments if there are:
- concerns about the accuracy of the SIF description
- any scientific data that should be considered before the SIF is amended
Our evaluators will review scientific questions or information for consideration in the evaluation. They will also evaluate non-scientific input and explore appropriate ways of addressing it.
Comments can be sent by email to the AFP at cfia.afp-paa.acia@inspection.gc.ca. Please use "polymethylolcarbamide" in the subject line of the email. We are asking for comments and feedback by December 29, 2025 30 days from the date of this posting.
Next steps
We will review all of the comments received. If no significant scientifically valid concerns are raised, we will finalize the amended description for polymethylolcarbamide.
If significant concerns are raised, we will evaluate the additional information.
This amended SIF description will be added to the CFIT at the next update.
