GST rate amendments revise tariff classifications and condition concessional treatment on brand-name ownership and affidavit-based relinquishment. The notification amends the State GST rate schedules to reclassify and re-describe numerous goods across multiple rate bands, inserting and omitting tariff entries and modifying exclusions; it defines brand name and registered brand name with a registration cut-off, conditions rate treatment on the existence of registered brand names or actionable claims/enforceable rights, and prescribes an Annexure procedure requiring an affidavit and bilingual indelible marking on unit containers where a packer voluntarily forgoes such rights.
