Guarantees and Product Warranties [Abstract]
Product Warranty	Product Warranty: PMI's IQOS devices are subject to standard product warranties generally for a period of 12 months from the date of purchase or such other periods as required by law. Estimated costs associated with warranty programs are generally provided for in cost of sales in the period the related revenue is recognized, and during 2017, PMI recorded $168 million associated with these product warranty programs. PMI assesses the adequacy of its accrued warranty liabilities and adjusts the amounts as necessary based on actual experience and changes in future estimates. Factors that affect warranty obligations may vary across markets but typically include product failure rates, logistics and service delivery costs, and warranty policies. At December 31, 2017, $71 million was accrued related to these warranty obligations within other accrued liabilities.
