IAS 2 Net Realizable Value Deductions for Factory Scrap Inventory
IAS 2 requires deducting factory scrap net realizable value from primary product cost, reducing inventory carrying basis and protecting gross margins.
Assay Moisture Allowance
Meaning
A contractual deduction applied to the gross wet weight of bulk commodities accounts for the weight of water contained in the material before final invoice settlement. Metal concentrate transactions rely on assay moisture allowance to convert raw delivery tons into dry pay units. Standard moisture determination involves heating a sample at one hundred and five degrees Celsius until it reaches a stable weight.
Any water exceeding the baseline threshold is deducted from the billable tonnage to prevent paying for useless moisture.
Contractual Threshold
Smelter agreements define the specific moisture level that is accepted without any commercial adjustment. When wet concentrate contains moisture below this specified limit, the shipper receives payment based on the measured dry weight without penalties. If moisture exceeds this limit, the assay moisture allowance is calculated to adjust the payable tonnage downward and may trigger drying penalties to cover the energy costs incurred by the processor.
This penalty structure encourages mining operations to run effective filtration systems before dispatching concentrates. Excessive moisture in maritime transit can also cause liquefaction, making moisture control a safety requirement as well as a financial necessity.
Financial Impact
Loss of marketable volume occurs directly when dry mass calculations reduce the billable tonnage after moisture testing. Mine operators face lower revenues when moisture levels exceed contractual thresholds because assay moisture allowance reduces the final settled weight. High water content also increases transport costs because the shipper pays freight on water that is eventually discounted at the smelter.
Reliable dewatering equipment prevents these financial losses by keeping moisture levels close to the agreed baseline.
Measurement Standard
Industry standards govern the collection and testing of samples to ensure the moisture percentage represents the entire shipment. Technicians collect sealed samples immediately after weighing to avoid evaporation before laboratory analysis is completed. The resulting assay moisture allowance provides a clear adjustment factor that resolves differences between shipper and receiver measurements.
Consistent sampling procedures protect both parties from disputes over weight discrepancy.
