Domestic Substances List Additions — Sep 2023

Summary#

This is the Order 2023-87-09-01 Amending the Domestic Substances List (SOR/2023-200). It adds several chemical substances to the Domestic Substances List, recognizing that they have been manufactured in or imported into Canada. The order was registered on September 27, 2023 and published in the Canada Gazette on October 11, 2023.

What it does#

• Adds three substances to Part 1 of the Domestic Substances List:
  • 5698-98-6 (listed as N)
  • 1815601-65-0 (listed as N‑P)
  • 2763070-25-1 (listed as N‑P)
• Adds six substances to Part 3 of the Domestic Substances List (CAS number followed by the chemical name as listed):
  • 19489-7 — Fatty acids, plant-based oil, conjugated, maleated
  • 19670-8 — 2-Propenoic acid, 2-methyl-, alkyl ester, polymer with dodecyl 2-methyl-2-propenoate, 2-hydroxyethyl 2-methyl-2-propenoate and methyl 2-methyl-2-propenoate
  • 19671-9 — Alkanoic acid, 12-hydroxy-, compound with heteromonocycle polymer with N1-(2-aminoalkyl)-1, alkylamine, 12-hydroxyoctadecanoic acid, 2-oxepanone and tetrahydro-2H-hetermonocycle
  • 19674-2 — 2-Propenoic acid, 2-methyl, alkyl ester, polymer with butyl 2-propenoate, 2-hydroxyethyl 2-methyl-2-propenoate, 2-hydroxyethyl 2-propenoate and methyl 2-methyl-2-propenoate
  • 19676-4 — 2-Propenoic acid, polymer with 2-hydroxyalkyl 2-propenoate and α-(alkylalkenyl)-ω-hydroxypoly(oxy-1,2-ethanediyl), graft
  • 19677-5 — 2-Ethyl-2-(hydroxymethyl)propane-1,3-diol polymer with 2,2-dimethylpropane-1,3-diol, benzene-1,4-dicarboxylic acid and ethane-1,2-diol, 2-hydroxy-3-[(alkanoyl)oxy]propyl ester
• The order was made under the Canadian Environmental Protection Act, 1999 after the government received information indicating these substances had been manufactured or imported in Canada in quantities above the threshold set in the New Substances Notification Regulations (Chemicals and Polymers).
• The order states the statutory assessment period had expired and that no special listing conditions were in effect when the order was made.

Who's affected#

• Companies that manufacture or import any of the listed substances into Canada.
• Businesses that use these substances in products or industrial processes (formulators, manufacturers, suppliers).
• Regulators and health/environment agencies that track chemical inventories.
• The Canada Gazette item does not describe specific products, industries, or uses for each substance, so it is not clear which downstream sectors will notice these additions most.

Why it matters#

• Being added to the Domestic Substances List means the chemicals are recognized as already being in Canadian commerce. That affects how they are treated under Canada’s new-substance rules.
• For manufacturers and importers, listing can remove the requirement to submit the same kind of "new substance" notifications that apply to chemicals not on the list.
• Listing does not by itself say a substance is safe or unsafe. If needed, separate assessments or controls could still be applied later.
• The order signals to businesses and regulators which substances are considered established in Canada; that can affect reporting, compliance planning, and product sourcing.
