The "Optional Register of Copper Exports" is created. Legal entities that invest in starting new productive projects can voluntarily adhere to this Register (i.e. it is not mandatory). It only applies to products 2603.00.10, 2603.00.90, and 2620.30.00. A "special tax rate" is applied to registered persons as an export tax; various cases are contemplated. Registered persons can stay in this scheme for 30 years from their registration date. For legal entities that choose not to register, the export tax of decree 1060/2020 applies.
