according to this excerpt from the article I posted earlier...
Banned on April 1st
Export records show that on April 10, Healgen received two shipments from Zhejiang Orient in China. COVID-19 test kits were in those shipments, Fang said, because they had been shipped before the April 1 ban.
On Wednesday, Aytu published a news release announcing that it had placed an order for 1 million test kits from an unidentified manufacturer. Disbrow, Aytu's chief executive, said in the release that another order for 500,000 tests was "awaiting customs clearance."
