S.C. Code § 12-49-910
The tax collector may levy upon and seize the personal property of a defaulting taxpayer by serving personally upon the delinquent taxpayer and the owner of such personal property, if it has been sold or transferred subject to the tax lien, a written notice that the specific personal property of the defaulting taxpayer has been seized pursuant to the direction and provisions of the particular delinquent tax execution. A description of such personal property as entered on the return of the taxpayer shall be a sufficient description of the personal property so seized. If the delinquent taxpayer or owner of such personal property is absent from the county or cannot be found therein, then service of such notice upon the agent, tenant, servant or employee of such delinquent taxpayer or owner of such personal property or other person in the custody, possession or control of it shall be sufficient. If the delinquent taxpayer or owner of such personal property cannot be found and there is no person in the custody, possession or control of it, such service shall be made by posting such notice on the building or at the place where said personal property is located.
