On September 4, FirstUnion e-cigarette released official news that it had successfully passed the US FDA review on August 25, 2020, and completed the first round of PMTA review.
On September 10, FirstUnion once again released official news that the second round of PMTA review will be completed with high quality on September 8, entering the final round.
Since there is no news about the time required for PMTA review before, the time of each round of PMTA review is unknown because every enterprise has to submit tens of thousands of pages of materials.
