COVID-19 (CoronaVirus) is a global pandemic virus that struck the world in early March of 2020. It has caused Amazon to temporarily restrict inbound FBA shipments into Amazon warehouses.
Here is the official update from Amazon from March 16th, 2020:
'We are closely monitoring the developments of COVID-19 and its impact on our customers, selling partners, and employees.
We are seeing increased online shopping, and as a result some products such as household staples and medical supplies are out of stock. With this in mind, we are temporarily prioritizing household staples, medical supplies, and other high-demand products coming into our fulfillment centers so that we can more quickly receive, restock, and deliver these products to customers.
For products other than these, we have temporarily disabled shipment creation. We are taking a similar approach with retail vendors.
This will be in effect today through April 5, 2020, and we will let you know once we resume regular operations. Shipments created before today will be received at fulfillment centers.
You can learn more about this on this Help page 2.0k. Please note that Selling Partner Support does not have further guidance.
We understand this is a change to your business, and we did not take this decision lightly. We are working around the clock to increase capacity and yesterday announced 441 that we are opening 100,000 new full- and part-time positions in our fulfillment centers across the US.
We appreciate your understanding as we prioritize the above products for our customers.
Thank you for your patience, and for participating in FBA.'
