Philip Morris International (PMI) filed a request to market its iQOS tobacco heating product with US regulators, the company said.

Last December, PMI asked the Food and Drug Administration (FDA) to grant its heating device, marketed under the iQOS brand, status as a Modified Risk Tobacco Product (MRTP). The subsequent Pre-market Tobacco Product Application (PMTA) also filed with FDA would allow PMI to market iQOS independent of the MRTP process. Altria, which owns Philip Morris USA, in a separate statement said it would market iQOS in the US under an exclusive arrangement with PMI in the event that FDA approves the pre-market application.
