The Act powers for all phases of the life cycle of a substance or product containing a substance (e.g. Manufacture, import, release, use, etc.). The Act also gives the Minister authority to maintain a Domestic Substances List (DSL). Substances listed on DSL are treated as Existing Chemical Substances in Canada and are managed by the Minister. Their toxicity evaluation and hazard assessment are done by Canada government. Meanwhile, substances that are not listed on DSL are treated as new substances and need file new substance notification.

There is another substance list under the Act, non-domestic Substance List (NDSL). NDSL is the list of substances accepted as being in use internationally (based on US TSCA inventory), but not cover all the other substances not on DSL. Substances on the NDSL still require new substance notification but allow less information submitted and higher allowable import/manufacture volume.

There are different data requirement for different tonnage band and substance types. Pls contact us for more information.
