South Carolina Code of Regulations — Chapter 117 (Revenue)
S.C. Code Regs. 117-311.2 — Railroad Companies-Crossties and Timbers
Crossties and timbers sold to or used by railroad companies are subject to the sales or use tax,
whichever may apply, on the following basis:
(a) Where a railroad buys in this state untreated ties or timber paying the South Carolina sales tax
due thereon, and thereafter has such ties or timber creosoted or otherwise treated either within or
without South Carolina, it becomes liable upon use of such property in South Carolina for the tax
based upon the sales price of the creosote or other material used in the treatment thereof.
(b) Where a railroad buys in South Carolina untreated ties and timber for shipment in interstate
commerce, without paying the South Carolina sales tax thereon, and such ties and timber are shipped
and creosoted without the state, and subsequently shipped into and used within the state, such railroad
will be required to pay a use tax thereon measured by the full price of the finished product brought
into the state.
(c) Where a railroad buys without the state untreated ties and timber, and thereafter brings said ties
and timber inside the state and has them creosoted within the state and uses them within the state,
such railroad would owe a use tax based upon the cost of untreated ties and timber, plus the sales price
of the creosote or other material used in the treatment thereof.
(d) Where a railroad buys without the state untreated ties and timber, and has the same creosoted
outside the state, and subsequently brings and uses the same within the state, such railroad would be
required to pay a use tax thereon based upon the cost of untreated ties and timber, plus the cost of
processing.
