S.C. Code Regs. § § 117-306.4
The shoe repairman is deemed to be engaged primarily in rendering services when he repairs property belonging to others. He is the purchaser for use or consumption of tangible property used by him in rendering such services. Consequently, the sale to the shoe repairman of articles of machinery and equipment and such supplies as sole leather, rubber heels, thread, nails and other findings for use in connection with rendering such services are sales at retail within the meaning of the sales and use tax law.
The sale of shoe laces, second hand shoes, package products and other like property constitutes sales of tangible personal property and as such bear the tax. The repairman making sales of such property is required to hold a retail license and to remit directly to the department the tax on such sales.
