If for personal no issues, it will be delivered directly to your P.O box (Company or Personal P.O box) depends on the address you provide to the seller.

I never encounter custom issues so far as I ordered many items from online like eBay, from china and US, Electronics like projector and electronics accessories etc... as long as personal used not a bulk orders.

If via QPOST you have to provide them your ID in order to claim it.
