Excise duty on tobacco products revised: specified ad valorem and specific rates and a narrow exemption apply to listed tobacco goods. Notification prescribes excise duties and limited exemptions for specified tobacco goods by Fourth Schedule tariff items, replacing a prior notification. It lists tariff classifications and assigns either ad valorem percentages or specific rupee-per-thousand rates for categories including unmanufactured tobacco, cigarettes (distinguished by filter and length), tobacco substitutes, gutkha, chewing tobacco, snuff, extracts, and reconstituted tobaccos, and specifies mixed charging rules where a percentage or a specific amount applies, including higher-of rules and a narrow exemption for unbranded, unpacked unmanufactured tobacco.
