Japan Chemical Substances Control Law (CSCL)
Importers of chemical substances have to comply with the Japan Chemical Substances Control Law (CSCL). This is similar to the obligations related to importers of substances into EU. The same threshold of 1 t/a per imported substance is applying for notification. Importing a chemical substance of 1 t/year or more into Japan requires notification with data under CSCL.
Other than REACH, in case of less than 1 t/year Low Volume Exemption (LVE) notification is required.
The purpose of the Japanese CSCL "is to evaluate, before manufacture or import, whether or not new chemical substances have properties such as persistence, and to implement necessary regulations, in order to prevent environmental pollution caused by chemical substances that are persistent and pose a risk of impairing human health or interfering with the inhabitation and/or growth of flora and fauna."
The chemical substances subject to the CSCL are those used for general industrial chemical products. Those substances that are subject to other regulations that are equally or more stringent regulations (or more specific to the usage of the substance are exempted from this law (food, feed additives, pharmaceuticals, cosmetics, agricultural chemicals, fertilizers).
