GST rate classification amendments refine tax treatment and impose brand related conditions with an affidavit and marking requirement. Amendments to the State GST rate notification modify numerous schedule entries to add, substitute or omit tariff items and to refine descriptive exclusions; they standardize treatment of goods 'put up in unit container' by requiring either a registered brand name or a brand with an actionable claim or enforceable right, subject to an Annexure procedure for voluntary forfeiture which requires an affidavit to the jurisdictional Commissioner and marking of unit containers.
