Recently customs inspections have become tougher. Without the reasons of a parcel come back to the sender. Dangerous freight, customs doesn't explain in detail about the decision.
I send by fast mail: EMS Russian Post.
Delivery two weeks, and even quicker.
But I resend some parcels. So far such cases was three.
I ask to pay attention to it and at an adverse situation to have patience, but not to open case with a claim.
Anyway, at the moment all parcels are safely delivered!!!
