No. The 3M facilities that produce these masks in China have been nationalized. Their supply chain is just fine. In fact they've ramped up production to 24x7, effectively producing at least 400% more than currently. However, for the time being, China has halted all exports.
Masks ARE produced in the US as well. Again, production has been ramped up, but we've got a SMALL issue with masks being hoarded (some of which may be shipped back to China). My understanding is that government agencies have taken over the initial shipments leaving the domestic factories, to divert them for best use. Which means that in a decade, when the next virus hits, someone will uncover a warehouse full of dusty pallets of these things.
And just to be clear, 3M is by no means the only manufacturer facing the mask crunch.

A surgical mask or fit-tested respirator should be worn by healthcare personnel who are within 6 feet of a suspected or laboratory-confirmed influenza patient.
