Customs duty amendments revise tariff rates and expand exemption lists, altering import eligibility and procedural conditions. Amendment revises the customs exemption notification by substituting the currency symbol, adjusting tariff column rates (notably replacing various 2% and 3% rates with 2.5% and increasing some 4% entries to 5%), inserting and omitting numerous serial entries identifying goods by tariff headings with specified concessional or nil duty, and rewording and reclassifying items. The Annexure imposes or clarifies eligibility and procedural conditions for export linked imports, aircraft import concessions, assay or registration requirements, and an accounting and bonding regime for spares and consumables used in repairs of ocean going vessels, plus additions to exemption lists and definitional clarifications.
