Shipments Outside the State***8212;When Sales Tax Does Not Apply. Sales tax does not apply when the property pursuant to the contract of sale, is required to be shipped and is shipped to a point outside this state by the retailer, by means of:
1. Facilities operated by the retailer, or
2. Delivery by the retailer to a carrier, customs broker or forwarding agent, whether hired by the purchaser or not, for shipment to such out-of-state point. As used herein the term "carrier" means a person or firm regularly engaged in the business of transporting for compensation tangible personal property owned by other persons, and includes both common and contract carriers. The term "forwarding agent" means a person or firm regularly engaged in the business of preparing property for shipment or arranging for its shipment. An individual or firm not otherwise so engaged does not become a "carrier" or "forwarding agent" within the meaning of this regulation simply by being designated by a purchaser to receive and ship goods to a point outside this state. (This subsection is effective on and after September 19, 1970, with respect to deliveries in California to carriers, etc., hired by the purchasers for shipment to points outside this state that are not in another state or foreign country, e.g., to points in the Pacific Ocean.)
