Overview of Canada New Substance Notification Regulation (NSNR)

from CIRS by

Canadian chemical substance list includes two parts: the Domestic Substance List (DSL), which records more than 23000 substances, and Non-Domestic Substance List (NDSL) which records almost 58000 substances.

DSL is used to identify whether a substance is classified as a new substance in Canada. If the substance is not on the DSL, the substance is regarded as a new substance. It shall be notified prior to manufacturing or importing. The NDSL determines the information to be provided. If a new substance is listed on the NDSL, a reduced data for notification may be required.

NSNR is appropriate for:

1. The domestic manufacturers in Canada

2. The importer within the borders of Canada

NSNR is inappropriate for:

1. The substance or polymer listed in DSL;

2. The packaged substance transferred via Canada; or

3. The substance regulated by other acts, such as Pest Control Act, Fertilizer Act, Feeds Act etc..
