South Carolina Code of Regulations
Chapter 117 - DEPARTMENT OF REVENUE
Article 11 - SALES AND USE TAX REGULATIONS
Section 117-334.1 - Goods coming into this State - Sales Tax

(A) When tangible personal property is purchased for use or consumption in this State and (1) the seller is engaged or continuing within this State in the business of selling tangible personal property at retail and (2) delivery is made in this State, such sale is subject to the sales tax if the order for the future delivery of tangible personal property is sent by the purchaser to, or the subsequent delivery of the property is made by, any local branch, office, outlet or other place of business of the retailer in this State, or agent or representative operating out of or having any connection with, such local branch, office, outlet or other place of business. The term "other place of business" as used herein includes, but is not limited to, the homes of district managers, representatives, and other resident employees, who perform services in relation to the seller's functions in this State. Participation in the transaction in any way by the local office, branch, outlet or other place of business is sufficient to sustain the sales tax.

If the conditions above are met it is immaterial (1) that the contract of sale is closed by acceptance outside the State or (2) that the contract is made before the property is brought into the State.

Delivery is held to have taken place in this State (1) when physical possession of the tangible personal property is actually transferred to the purchaser or the purchaser's designee within this State, or (2) when the tangible personal property is placed in the mails at a point outside this State and directed to the purchaser or the purchaser's designee in this State or (3) when the tangible personal property is placed on board a carrier at a point outside this State (regardless of shipping terms) and directed to the purchaser or the purchaser's designee in this State.

The term "engaged or continuing within this State in the business of selling tangible personal property at retail" as used in this regulation shall have the same meaning as the term "retailer maintaining a place of business in this State" as defined in Code Section 12-36-80.

(B) When tangible personal property is brought into this State by the seller, or an agent, salesman, or other representative of the seller, for sale at a permanent or temporary location (carnivals, festivals, roadside, etc.) or from a truck or other vehicle, such sale is subject to the sales tax.
