It’s either awaiting export or import clearance- I know they start import clearance while flights are in the air but it seems a bit early for US import clearance to have started. Hopefully it’s not still sitting in China, but I agree there’s still time for the date to move up even if it is.
Yes, some indications like you mentioned that it could already be in air. The tracking of pallets and updates are alwayys a bit behind. I love how the mass opening day shipments sometimes will miss most of tracking til scan and checkin at Louisville when pallets are broken up and they get shipped all over US
