Yes, I think that this is the biggest threat. It seems that the Chinese economy basically halted, and done so in a very rapid and unplanned fashion. Both China's internal steps to limit the spread and the international reaction of closing borders has shut down most economic activity.
Most air freight travel on passenger flights, so with all the airlines cancelling flights direct consumer order goods won't be able to leave China.
Chinese factories have shut down and its not clear when they will reopen, so bulk commercial purchases will not be available once current stocks are exhausted.
