Customs exemption amendment expands port designations and excludes specified beneficiary units from certain notification benefits. A central government customs notification amends three miscellaneous exemption notifications by substituting wording to include Haldia (Haldia Dock Complex of Kolkata Port) alongside Vadinar and to include Dabolim (Goa) alongside Indore, thereby expanding listed port and location designations; it also inserts proviso language in specified conditions to exclude units already availing certain central excise notification benefits, narrowing eligible beneficiaries under those provisos.
