Sealed phone shipping thru LBC

Quick question lang. So I have a new phone that needs to get shipped here in Manila from Mindanao via LBC. They said that they need to open the box due to protocol para sa insurance. Do they really have to kasi sealed pa naman? Just asking to make sure lang kasi may ibang online stores naman na nagpapadala via LBC and sealed pa naman yung box. Kinakabahan lang ako kasi iPhone yun haha! Salamat sa sasagot.
