The document outlines the valuation rules under the Central Excise Act to determine the assessable value of excisable goods if the value cannot be determined under section 4(1)(a) of the Act. The key points covered are: (1) the Central Excise Valuation Rules 2000 provide the methodology; (2) if goods are not sold at removal, the value will be based on similar goods sold nearest to removal with adjustments; (3) samples distributed free are valued based on rule 4; and (4) if sale price is not the sole consideration, the value includes additional consideration received.
