Financial Adjustment
The final reconciliation of accounts between fiber suppliers and spinning mills is based on the standardized commercial weight of the delivered material rather than its raw weight. This process of invoice settlement accounts for the difference between the actual moisture content of the cotton or wool and the official moisture allowance. This mechanism protects both parties from the financial impact of natural humidity fluctuations.
Moisture Allowance
Contractual agreements in the international textile trade specify an official moisture regain percentage for each fiber type. During invoice settlement, the actual shipment weight is adjusted to represent what the fiber would weigh if it contained exactly the agreed moisture regain. For example, cotton contracts typically specify a moisture regain of eight point five percent.
If the shipment is drier than this standard, the adjusted weight increases, and the buyer pays more to compensate the supplier for the higher concentration of actual fiber. Conversely, if the bales are too wet, the billing weight is reduced accordingly to prevent the buyer from purchasing water.
Weight Correction
To calculate the final billable weight, laboratory moisture tests are conducted on representative samples taken from the shipment upon arrival. The data generated from these tests are used during invoice settlement to execute the weight correction formulas defined by international standards. This adjustment ensures that mills do not pay for excess water trapped in damp bales.
Payment Execution
The documentation required to complete the financial transaction includes moisture certificates issued by independent testing laboratories. Once the adjusted weight is finalized during invoice settlement, the finance department authorizes the final payment to the supplier. This step completes the purchasing cycle and establishes a clear audit trail for the transaction.
Accurate weight calculation is necessary to maintain trusted commercial relationships between global suppliers and mills.
