Notice of Excess Quantity (NOEQ) and Notice of Manufacture Import (NOMI) under the Canadian New Substances Notification Regulations (NSNR)

Under the Canadian New Substances Notification Regulations (NSNR) tiered notification system, a substance can be added to the Domestic Substances List once all four of the following criteria have been met:

• The highest level new substances notification (NSN) has been submitted;
• The government's assessment period for has expired;
• No notifier-specific restrictions, such as a Ministerial Condition, on the manufacture, importation, use, or disposal of the substance have been imposed; and
• The government has received the notifier's "Notice of Excess Quantity" (NOEQ) indicating that the notifier has manufactured or imported the greatest quantity of substance that triggered the highest NSN. The NOEQ is filed within 30 days after the notifier has commenced importing or manufacturing the substance in the greater quantities (i.e., the "Quantity of Excess") that is allowed following government approval of the highest NSN.

Alternatively, a "Notice of Manufacture/Import" (NOMI) allows companies to replace the 4th DSL eligibility criteria (i.e., the NOEQ requirement described above). Companies may submit a "Notice" confirming the manufacture or import of the substance in Canada.

Once a substance is added to the Domestic Substances List (DSL), no further notification by anyone manufacturing or importing the substance is required under the NSNR program, unless the DSL entry for that substance is specifically flagged with an “S”-flag indicating a Significant New Activity condition (SNAc), or a “P”-flag denoting a polymer’s reduced regulatory requirement status.
