Retail sale price valuation rule for specified tobacco and pan masala products prescribes deemed value and tax extraction method. Rule 31D deems the value of specified packaged goods to be the declared retail sale price less the amount of tax, for goods listed including pan masala and tobacco products; tax amount is computed as (Retail sale price x applicable tax rate) / (100 + sum of applicable tax rate), with definitions for applicable tax and retail sale price and rules for multiple, altered or area-specific declared prices. Rule 86B is amended to exempt registered persons other than manufacturers in respect of goods under Rule 31D when the supplier has paid tax on the basis of retail sale price.
