Five Substances Added to Domestic List

Summary#

Order 2023-87-02-01 Amending the Domestic Substances List adds five substances (one chemical and four polymers) to the federal inventory of substances in Canada, the Domestic Substances List. The Order was registered and came into force on January 23, 2023, and was published in the Canada Gazette on February 1, 2023.

What it does#

• Adds these five entries to Part 1 of the Domestic Substances List (listed by their CAS Registry Numbers exactly as in the Order):
  • 128446-60-6 N
  • 245678-22-2 N‑P
  • 1462343-28-7 N
  • 2180952-57-0 N‑P
  • 2682937-26-2 N
  • The Order itself does not explain the letter annotations (the source just shows them).
• Because those substances are now on the Domestic Substances List, they are no longer subject to the notification and assessment requirements of the New Substances Notification Regulations (Chemicals and Polymers).
• The Order is described in the source as administrative: it does not create new regulatory obligations, does not endorse the substances, and does not exempt them from other laws that might apply.

Who's affected#

• Manufacturers and importers who make or bring these specific substances into Canada.
• Chemical suppliers and companies that buy or use these substances in products or processes.
• Environment and Climate Change Canada (the federal department responsible for the list) and other regulators who track and regulate chemicals.
• The source does not say which industries or end uses rely on these specific CAS-numbered substances, so it is unclear which sectors will notice the change most.

Why it matters#

• Being on the Domestic Substances List means companies can import or manufacture these substances without going through the New Substances notification process that applies to substances not on the list. That can make commercial access easier and faster.
• The change is administrative only: it does not mean the government has declared the substances safe, nor does it remove any other environmental, health or safety rules that might apply.
• The source says there were no extra costs or new requirements for businesses and no public comment period was required for this addition.
