In one line
From 1 February 2026 the value of pan masala, tobacco, cigarettes, cigars and similar goods listed in the rule is the retail sale price declared on the pack, less the tax it contains. Tax is backed out as (RSP x rate) divided by (100 + rate). This shifts these goods from transaction value to a printed-price basis, so the invoice price no longer decides the tax.
