Va. Code § 58.1-415
Sales of tangible personal property are in the Commonwealth if such property is received in the Commonwealth by the purchaser. In the case of delivery by common carrier or other means of transportation, the place at which such property is ultimately received after all transportation has been completed shall be considered as the place at which such property is received by the purchaser. Direct delivery in the Commonwealth, other than for purposes of transportation, to a person or firm designated by a purchaser, constitutes delivery to the purchaser in the Commonwealth, and direct delivery outside the Commonwealth to a person or firm designated by the purchaser does not constitute delivery to the purchaser in the Commonwealth, regardless of where title passes, or other conditions of sale.
