Customs duty exemption for specified Australian imports applies through tariff-wise concessions, quota limits, and proof of origin requirements. Customs duty exemption is provided for specified goods imported into India from Australia under the Customs Act, 1962. The notification applies different concession structures to listed tariff items, including full or partial exemption from basic customs duty, reduced basic customs duty and Agriculture Infrastructure and Development Cess, and quota-based concessions subject to annual import limits and annexed conditions. The benefit is available only where the importer proves Australian origin under the applicable rules of origin.
