Add eight substances to Domestic Substances List

Summary#

Order 2021-87-06-01 Amending the Domestic Substances List adds several chemical substances to Canada’s official inventory of chemicals, the Domestic Substances List. The order was registered on May 7, 2021 and published in the Canada Gazette, Part II on May 26, 2021.

What it does#

• Adds four substances (by CAS number) to Part 1 of the Domestic Substances List:
  • 27289-84-5 (marked N‑P)
  • 76326-99-3 (marked N)
  • 86013-04-9 (marked N‑P)
  • 2476425-14-4 (marked N‑P)
• Adds four substances (CAS numbers and chemical descriptions) to Part 3 of the Domestic Substances List:
  • 19519-7 — Octadecanoic acid, 12-hydroxy-, polymer with aziridine, 2-oxepanone and tetrahydro-2H-pyran-2-one, reaction products with heteropolycycle disubstituted
  • 19521-9 — Ethanol,‑nitrilotris‑, compounds with modified polyethylene
  • 19522-0 — Alkenedioic acid, polymer with 1‑propene, compound with (dialkylamino)alkanol
  • 19523-1 — Alkenoic acid, alkyl, alkyl ester, polymers with alkyl alkenoate and substituted ... (full name in the Gazette)
• Comes into force on the day it was registered (registration date May 7, 2021).

Note: The entries in the Gazette include short codes like “N” and “N‑P.” The document does not explain those codes; their specific meanings are not stated in this notice.

Who's affected#

• Businesses that make, import, sell or use the listed chemicals in Canada are the most likely to notice this change.
• Federal regulators and the people who track chemical inventories and reporting will also be affected.
• The general public is unlikely to see immediate changes unless these specific chemicals are in consumer products they use.

Why it matters#

• Being added to the Domestic Substances List means these chemicals are officially recorded as present or reported in Canada.
• That can be the first step before any government assessments, reporting requirements, or controls are considered in the future.
• If you work with chemicals, this change could affect your reporting or compliance obligations; if you’re a consumer, it signals that regulators are tracking these substances in the Canadian market.
