Yesterday Amazon announced that they would be prioritizing FBA shipments.
This means that certain categories will not be able to ship anything into Amazon FBA warehouses until April 5th

Some of the more “Essential Categories” and products with high demand, will still be allowed to ship.

What products am I able to ship to FBA?
