Substance 54590-72-6 Added to DSL

Summary#

Order 2020-66-05-01 Amending the Domestic Substances List adds the chemical identified by 54590-72-6 to Part 1 of Canada’s Domestic Substances List. The order was registered on February 3, 2020 and came into force on that day.

What it does#

• Adds 54590-72-6 to Part 1 of the Domestic Substances List.
• Records that the Minister of the Environment (signed by Jonathan Wilkinson) was satisfied the substance was imported into Canada in a quantity of at least 100 kg in a single year between January 1, 1984 and December 31, 1986, a condition in the Canadian Environmental Protection Act, 1999.
• The Order states it comes into force on the day it is registered (which is February 3, 2020).

Who's affected#

• Companies that import, manufacture, sell or use the substance listed as 54590-72-6 in Canada.
• Government regulators and environmental professionals who track and manage chemicals in commerce.
• The public and communities near sites where the substance is handled, if that substance is used locally.
  Note: The Gazette notice gives only the CAS number (54590-72-6) and does not say the common name, uses, or how widely the substance is used, so it is unclear which specific industries or products are involved.

Why it matters#

• Being on the Domestic Substances List generally marks a chemical as an “existing” substance in Canada. That status can change how it is reviewed and whether firms must notify it as a new chemical under Canada’s chemicals rules.
• For businesses, the listing can affect reporting and regulatory steps they must take when importing or using the substance.
• For the public, listing helps regulators keep track of what chemicals are present in Canada and can influence future assessments or management actions. The Gazette item itself does not spell out any direct regulatory consequences beyond adding the substance to the list.
