What does this even mean?

That your package is going through customs ...

Pray your shipper is competent. Mine didn’t know wtf they were doing - provided the incorrect HTS code, didn’t fill out some worksheet correctly, etc. Triggered a formal entry process with customs that only now cleared after over a week of back and forth with DHL. Customs was saying a car/truck entry form needed to be provided… for a wristwatch. Complete disaster.
