Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	Altria’s businesses record an allowance for returned goods, which is included in other accrued liabilities on Altria’s condensed consolidated balance sheets. While all of Altria’s tobacco operating companies sell tobacco products with dates relative to freshness as printed on product packaging, it is USSTC’s policy to accept authorized sales returns from its customers for products that have passed such dates due to the limited shelf life of USSTC’s MST and snus products. Altria’s businesses record estimated sales returns, which are based principally on historical volume and return rates, as a reduction to revenues. Actual sales returns will differ from estimated sales returns to the extent actual results differ from estimated assumptions. Altria’s businesses reflect differences between actual and estimated sales returns in the period in which the actual amounts become known. These differences, if any, have not had a material impact on Altria’s condensed consolidated financial statements. All returned goods are destroyed upon return and not included in inventory. Consequently, Altria’s businesses do not record an asset for their right to recover goods from customers upon return.
