(A) To Other States—When Sales Tax Applies. Except as otherwise provided in (B) below, sales tax applies when the property is delivered to the purchaser or the purchaser's representative in this state, whether or not the disclosed or undisclosed intention of the purchaser is to transport the property to a point outside this state, and whether or not the property is actually so transported. It is immaterial that the contract of sale may have called for the shipment by the retailer of the property to a point outside this state, or that the property was made to specifications for out-of-state jobs, that prices were quoted including transportation charges to out-of-state points, or that the goods are delivered to the purchaser in this state via a route a portion of which is outside this state. Regardless of the documentary evidence held by the retailer (see (3)(D) below) to show delivery of the property was made to a carrier for shipment to a point outside the state, tax will apply if the property is diverted in transit to the purchaser or his representative in this state, or for any other reason it is not delivered outside this state.
B) Shipments Outside the State—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.)
