VTC Transparency in Pricing

BLS Price Adjustment


To clearly assist clients in understanding how transparent pricing adjustments are taken, we have implemented use of the U.S. BLS. VTC’s selling price is adjusted at the time of shipment based on a monthly price index as described in this policy. The current price index will be based on the BLS Price Index for the prior month. The price at shipment is the quoted price times the price index ratio at the time of shipment. Any resulting purchase order would acknowledge this Price Adjustment Policy. We are always happy to work with clients on their needs and provide this as an effort to make sure any changes are upfront and easily understood.


The price index will be used to calculate the adjustment applied to the price at shipment per the below equation:


  • Iq = New BLS Price Index for month of shipment
  • I0 = Original BLS Price Index at time of quote
  • Pn = New Price at shipment after adjustment
  • P0 = Original Price at time of quote

Customer price would be increased or decreased at the time of shipment as indicated by the index ratio. The quote proposal will contain the index used at time of proposal.
