Seven Chemicals Added to Domestic Substances List

Summary#

This is the Order 2020-87-15-01 Amending the Domestic Substances List (SOR/2020-273). It adds seven chemical substances to the Domestic Substances List and took effect on December 13, 2020. The order was made under the Canadian Environmental Protection Act, 1999 and signed by Jonathan Wilkinson, the Minister of the Environment.

What it does#

• Adds the following CAS numbers to Part 1 of the Domestic Substances List: 3084-40-0, 13718-94-0, 31727-13-6, 646054-62-8, 1373521-46-0.
• Adds the following entries to Part 3 of the List:
  • 19491-9 — Carbonic acid, dialkyl ester, polymer with 1,4-butanediol, 1,6-hexanediol and 1,1′-alkenylbis[4-isocyanatobenzene].
  • 19492-0 — 2-Propenoic acid, 2-hydroxyalkyl ester, reaction products with O,O-bis(1,3-dialkylalkyl) hydrogen phosphorodithioate and dialkyl phosphonate.
• The order states the government received required information, the period for assessing that information ended, and there were no control conditions in force for these substances. The order came into force on the day it was registered (December 13, 2020).

Who's affected#

• Companies that make, import, sell, or use the specific chemicals listed above are the most likely to notice this change.
• Chemical suppliers, industrial users, and environmental compliance staff will be the groups most directly concerned.
• The entry does not list particular industries or uses, so it is unclear which products or sectors will be affected without checking each substance's commercial uses.

Why it matters#

• Being added to the Domestic Substances List generally means a chemical is treated as an “existing” substance in Canada rather than a new one. In practice, that typically affects whether firms must submit pre-market “new substance” notifications under the Canadian Environmental Protection Act, 1999.
• For businesses, this can change the paperwork and timing needed to bring these chemicals into Canadian commerce. For regulators and the public, it records that the government has received and reviewed information on these substances and did not place conditions on them at this time.
