Financial Reconciliation
Contractual financial reconciliation revises raw fleece transaction prices following laboratory determination of clean wool content. A formal scoured yield adjustment modifies the final invoice amount based on certified washing results compared against initial provisional estimates. Raw greasy animal hair carries variable quantities of grease, dirt, and vegetable matter that cannot be measured by visual inspection alone.
The scope of this mechanism is financial settlement for commercial lots, excluding technical adjustments to scouring machine settings.
Yield Calculation
Testing laboratories extract core samples from greasy bales to wash out soluble suint and dirt. Oven-drying yields clean wool content plus standard regain, establishing the certified clean percentage. Contracts apply this percentage to gross consignment mass to calculate net clean mass.
Impurity Determination
Residual vegetable matter such as seeds and burrs requires chemical dissolution or mechanical removal during processing. High vegetable matter content reduces usable fibre mass while increasing processing costs for topmakers. Scouring tests determine the exact percentage of hard vegetable impurities to apply accurate yield deductions.
Buyers and sellers accept certified laboratory yield documents as binding proof for invoice recalculation. Divergence between estimated raw yield and actual laboratory yield alters final payment totals across major commercial shipments.
Contract Settlement
Final payment adjustments reconcile differences between initial deposit payments and verified clean yield values. Financial settlement closes raw material purchasing contracts.
