A certificate of current cost or pricing data is a signed statement from a bidder stating that, to the best of the bidder's knowledge and belief, the costs or pricing data which they have submitted in a tender are accurate, complete and current at the time.
A form for such submission is available in the Federal Acquisition Regulation (FAR) at section 15.406-2.
