Hi, Suresh D.
Usually it is door delivery service. However, in some cases, it is Post Office delivery. As it is international shipping, it may happen that you need to pick up the parcel or ask your local post office for re-delivery if the parcel is held there. Please kindly pay attention to the tracking information.

Further assistance, please feel free to contact the customer service. Here is the link.
