Meaning
Contractual clauses that allow for the modification of unit costs in response to fluctuations in raw material or labor expenses protect the margins of both parties. A price adjustment mechanism links the final invoice to an objective third party index such as the London Metal Exchange or the China Producer Price Index.
Trigger Condition
Parties agree that a change in the index of more than 5 percent within a quarter activates the review process. This price adjustment mechanism prevents the sudden insolvency of a supplier when the price of plastic resins or copper spikes unexpectedly.
Formula Design
The calculation usually accounts for the portion of the total cost attributed to the volatile material. If aluminum makes up 40 percent of the product value, the price adjustment mechanism applies the index change only to that specific fraction of the price. This formula must be clearly defined in the supply contract to avoid disagreements during the billing cycle.
Implementation Procedure
Buyers and sellers must exchange formal notices and data sheets before the new rate takes effect. Failure to define a clear price adjustment mechanism leads to protracted disputes and potential supply chain disruptions during periods of high inflation.
