The notification substitutes, inserts and omits tariff entries (adding specific headings and carve-outs), clarifies 'brand name' and 'registered brand name' definitions, and prescribes an ANNEXURE procedure for voluntarily foregoing actionable claims or enforceable rights in brand names, including affidavit filing and bilingual notice on unit containers; the changes are given retrospective effect.
