14 Substances Added to Domestic List

Summary#

Order 2021-87-04-01 Amending the Domestic Substances List (SOR/2021-79) adds 14 substances to Canada’s chemical inventory, the Domestic Substances List. The order was registered on April 9, 2021 and published in the Canada Gazette on April 28, 2021; it came into force on the registration date.

What it does#

• Adds 8 substances identified by their CAS Registry Numbers to Part 1 of the Domestic Substances List:
  • 17465-86-0
  • 28572-30-7
  • 69215-54-9
  • 910661-93-7
  • 1218992-20-1
  • 1355214-14-0
  • 1613243-54-1
  • 2216701-91-4
• Adds 6 substances identified by masked names and Confidential Accession Numbers (CANs) to Part 3 of the Domestic Substances List:
  • 19499-7 — Benzoic acid, 2,2′-[[2,4(3,5 or 4,6)-dihydroxyphenylene]bis(2,1-diazenediyl)]bis-, 1,1′-bis[(dialkylamino)alkyl] ester, hydrochloride (1:2)
  • 19514-2 — Imidazoimidazoledione, tetrahydrotetrakis(methoxymethyl)-, polymer with hydrohydroxypoly(oxyalkanediyl), reaction products with polyethylene glycol mono[tris(phenylalkyl)phenyl]ether
  • 19515-3 — Heteropolycycledione, tetrahydro-, polymer with 1,2-ethanediol, 2,5-furandione, 2,2′-oxybis[ethanol] and 1,2-propanediol
  • 19516-4 — Substituted benzene, 4,4′-(1-methylethylidene)bis-, polymer with α-(2-aminomethylethyl)-ω-(2-substituted alkylalkoxy)poly[oxy(methyl-1,2-ethanediyl)] and 2,2′-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[heteromonocycle], alkanoate (salt)
  • 19517-5 — 2-Propenoic acid, butyl ester, polymer with 2-ethylalkyl alkenoate, phenylmethyl ester
  • 19518-6 — Carbomonocycle alcohol, 2,2′-[(4-methoxyphenyl)heteromonocyclediyl]bis[5-[(2-ethylalkyl)oxy]-
• Because these substances are added to the Domestic Substances List, they are no longer subject to the New Substances Notification Regulations (Chemicals and Polymers) for new-substance notification.
• The order itself does not introduce new controls or conditions for these substances. The entry also notes it does not amount to a government endorsement or an exemption from any other laws or regulations.

Note: the list entries include short codes such as “N” and “N‑P” shown next to some numbers in the official list. The document does not explain those codes in this notice.

Who's affected#

• Businesses that manufacture or import the listed substances into Canada. Adding a substance to the list means those companies no longer need to submit a new-substance notification under the rules that apply to brand-new chemicals.
• Chemical suppliers and downstream users (manufacturers, formulators, distributors) who may buy, sell, or use these substances in products or processes.
• Regulators and compliance officers tracking which substances are on Canada’s inventory.
• The notice says there are no new compliance costs, and a small-business review concluded no expected impact on small businesses.

If it’s unclear whether a specific company or product is affected, the order itself does not give that level of detail; affected firms will know based on whether they handle the listed substances.

Why it matters#

• Practical effect: companies that already imported or manufactured these substances in Canada and provided the required information can now use, sell, or import them without repeating the “new substance” notification process. That can make market access quicker and reduce paperwork.
• This is an administrative step, not a safety approval. The government explicitly says the order is not an endorsement of the substances, and other laws or rules (for example, product safety, workplace safety, or environmental rules) can still apply.
• For members of the public, the order means these specific chemicals are officially part of Canada’s inventory of existing substances. If you work with chemicals, buy products that contain them, or follow environmental or health rules, this change could affect labeling, reporting, or regulatory checks downstream.
