Substance 321657-09-4 moved to Domestic List

Summary#

Order 2025-87-10-02 Amending the Non-domestic Substances List removes one chemical from the federal list of substances thought not to be in Canadian commerce. The change was made by Julie Dabrusin, Minister of the Environment, on October 23, 2025 and was published in the Canada Gazette on November 15, 2025.

What it does#

• Deletes the entry 321657-09-4 from Part I of the Non‑domestic Substances List.
• The Order says that the same substance has been added to the Domestic Substances List under the Canadian Environmental Protection Act, 1999.
• The Order takes effect on the day that Order 2025-87-10-01 Amending the Domestic Substances List comes into force.

Who's affected#

• Likely to be noticed by chemical manufacturers, importers and companies that use the substance listed as 321657-09-4.
• Environmental and regulatory staff at federal, provincial or territorial bodies who track which chemicals are on the government lists.
• It is unclear from the notice whether any specific companies or users were directly notified or what immediate actions they must take.

Why it matters#

• Being on the Domestic Substances List rather than the Non‑domestic Substances List is a formal signal that the government considers the substance to be present or in use in Canada.
• That can affect how the government tracks, assesses or manages the substance and may trigger different reporting, testing or review steps.
• For businesses that make, import or handle this chemical, the change could mean closer regulatory attention or new information requests — the notice itself does not list any new obligations.
