Certain manufacturers in the operation of their businesses purchase for their customers patterns which are used by the manufacturers in the production of property for sale to their customers. When such patterns are received by the manufacturers, they are then sold to the manufacturers' customers. The manufacturers purchase these patterns at wholesale and sell them to their customers at retail. The manufacturers' sale to their customers are subject to tax even though the customer is a nonresident of South Carolina and even though the pattern, after use by the manufacturer in South Carolina, may be shipped to the customer outside the state.
