Meaning
Cost adjustment mechanisms reconcile estimated production expenses with actual expenditures at the end of a specified accounting period. In plastic moulding, a true-up settlement balances the cost of resin, energy, or tooling against the initial projections. If the price of resin has fluctuated, the unit price of the part is adjusted.
This reconciliation ensures both the moulder and the client share the burden of volatile raw material prices.
Material Escalation
Raw material price indices guide the adjustments during the contract period. When the market price of polypropylene rises or falls, a true-up settlement recalculates the material surcharge on a quarterly basis. This adjustment is based on a pre-determined formula.
This formula reduces the risk for both parties when contract manufacturing spans several years.
Volatility Recovery
Underestimating material consumption during the trial phase can lead to losses for the manufacturer. By implementing a true-up settlement, the moulder recovers the difference between the estimated regrind threshold and the actual regrind used in production. If the client insisted on virgin resin, the cost difference is recovered.
This recovery maintains the agreed-upon profit margins, ensuring that any deviation in the scrap rate does not erode the financial viability of the long-term supply agreement.
Accounting Process
Invoicing adjustments are finalized within thirty days of the period’s end. The audit compares the delivery notes against the baseline prices. This process ensures transparency and builds trust.
