Customs tariff amendments revise duty rates and add GI and standards-based classification notes across the schedule. Comprehensive revisions to the First Schedule of the Customs Tariff Act substitute new tariff descriptions and duty rates for numerous items and headings, add or amend Supplementary and Sub heading Notes to clarify classification, measurement bases and references to the latest standards, and recognise select Geographical Indication products by linking descriptions and duty entries to certified GI registry users, thereby reconfiguring classification lines and the duty assessment framework across multiple chapters.
