Domestic Substances List: New Additions

Summary#

Order 2024-87-01-01 Amending the Domestic Substances List adds several chemicals to Canada’s list of substances that are known to be present in the country. The order was registered on January 18, 2024, which is the day it comes into force.

What it does#

• Adds the following CAS numbers to Part 1 of the Domestic Substances List:
  • 30026-62-1
  • 49556-16-3
  • 70900-22-0
  • 125121-38-2
  • 399024-75-0
  • 502618-47-5
  • 1186225-21-7
  • 1662663-05-9
  • 2765086-37-9
• Adds the following entries to Part 3 of the Domestic Substances List:
  • 19434-2 — Heteropolycyclic alkanol, carbomonocycle-, alkanesulfonate
  • 19694-2 — Fatty acids, plant-based, polymers with adipic acid, bisphenol A, conjugated sunflower-oil fatty acids and epichlorohydrin
• The amendments were made under the Canadian Environmental Protection Act, 1999 after information showed these substances had been manufactured in or imported into Canada above the reporting thresholds set in the New Substances Notification Regulations (Chemicals and Polymers).

Who's affected#

• Companies that manufacture, import, or supply the listed chemicals in Canada are the most likely to notice this change.
• The people or businesses that provided the information used to add these substances are directly involved, since the order notes they reported quantities above the regulatory threshold.
• For the general public, the change mainly matters if you work with or are exposed to chemicals in these categories (e.g., certain industrial, manufacturing, or chemical-processing settings).

Why it matters#

• Being placed on the Domestic Substances List means these chemicals are recognized as already present in Canadian commerce. In practical terms, that affects how federal new-substance rules apply to them — they are not treated as "new" for the New Substances Notification Regulations.
• For businesses, this can change what notifications or pre-market information they must provide when handling these substances.
• For communities and workers, the addition signals these specific substances are in use in Canada; if you have concerns about exposure, safety data sheets and employer controls are places to look for more information.
