Bubble ratio too large

4PX Express tracking parcel

What this status means

"Bubble ratio too large" is a note from 4PX Express's warehouse or sorting checks. It usually refers to volumetric weight. The parcel is bulky compared with its real weight, which often happens with light items in oversized or heavily padded packaging. The parcel is at a 4PX facility, early in its journey, and its size and weight are not matching what was declared or expected.

Is my package delayed?

This message is an exception, though not always a serious one. It most often appears right after pickup, and in about 70% of cases the next step is "Shipment arrived at facility and measured", so the parcel simply carries on. In some cases, about one in ten, the parcel is instead returned. Any delay depends on whether the parcel can be repacked or re-rated.

What happens next

  • Most often, the parcel is measured at the facility and moves on in the normal flow.
  • Sometimes, shipment information is sent again to the onward carrier or a new shipping order is created.
  • Less often, the status changes to "Return to customers", meaning the parcel is sent back.

What you can do

  • Wait and keep checking the tracking history for the next update.
  • If the status stays the same for longer than the previous steps took, contact the seller first. They can tell whether the packaging or shipping fee is the problem.
  • If you see "Return to customers", ask the seller about a reshipment or refund.
  • Have your tracking number and order details ready when you get in touch.
