Invoice Mass
Quantitative financial adjustments applied to the dry weight of textile shipments determine the official billable mass based on standardized moisture regain values. Executing a commercial weight calculation reconciles oven-dry fiber weight with official commercial moisture allowances. This financial method governs international trade of raw wool and synthetic yarns, stopping short of physical quality testing or fiber identification.
Moisture Addition
Fibers absorb atmospheric water vapor in proportions dictated by their chemical structure and environmental humidity. Applying a commercial weight calculation adds the official moisture percentage back to the completely dried specimen weight. Standardized regain figures range from eight point five percent for wool to zero percent for hydrophobic synthetics.
Allowance Percentage
Trading agreements specify fixed percentage allowances for moisture and commercial finish oils. Incorporating these percentages into a commercial weight calculation prevents dispute over weight changes caused by humidity shifts during sea transit. Shippers weigh desiccated samples from sealed bales to compute total commercial weight across entire containers.
Contract Settlement
Commercial invoices base final payment amounts directly on certified weight certificates issued by accredited testing houses. Applying a commercial weight calculation ensures that buyers pay for dry fiber mass plus official moisture rather than absorbed water gained in transit. Contracts settle accounts using these certified figures to eliminate transit weight disputes.
