Domestic Substances List updated for N-P entries

Summary#

Order 2026-87-09-01 Amending the Domestic Substances List updates entries on Canada’s Domestic Substances List. It removes one listing, adds two entries to Part 1, and adds one entry to Part 3. The Order was registered and came into force on July 22, 2026; it was published in the Canada Gazette on August 12, 2026 and signed by Julie Dabrusin.

What it does#

• Removes from Part 1 the entry 82780-16-3 N-P.
• Adds to Part 1 the entries 82780-16-3 N and 3057850-65-1 N-P.
• Adds to Part 3 the entry 19838-6 N-P with the chemical name 1,4-Benzenedicarboxylic acid, dimethyl ester, polymer with 1,4-butanediol, alkanedioic acid, alkyl diol, 1,1’-methylenebis[4‑isocyanatobenzene] and methylalkanediol.
• The Order says it comes into force on the day it is registered (which is July 22, 2026).
• The notice indicates a Regulatory Impact Analysis Statement for this Order is published separately (following SOR/2026-164).

Who's affected#

• Companies that manufacture, import, or use the listed chemicals in Canada.
• Chemical suppliers and downstream users (manufacturers that buy those substances as inputs).
• Environmental consultants and compliance officers who track chemical listings.
• Government regulators who keep the Domestic Substances List updated.

If it is unclear how the new codes (the “N” and “N‑P” labels) change legal obligations, the Order itself does not explain that — affected parties may need to consult the Domestic Substances List, the Department that manages it, or the separate Regulatory Impact Analysis Statement.

Why it matters#

• The Domestic Substances List is the federal record of substances in commerce in Canada. Changes to it can affect how a chemical is tracked, assessed, or regulated.
• Businesses that handle these specific substances may need to check whether the new entries change their reporting or compliance responsibilities.
• The short notice and separate Regulatory Impact Analysis Statement mean anyone affected should read the RIAS (referenced in the Gazette) or contact Environment authorities to understand concrete impacts.
