Standard Moisture Regain Determination in Scutched Flax Fibre
Standard moisture regain in scutched flax fibre is set at 12.0% of bone-dry mass using ISO 6741-1 forced-convection oven drying at 105 degrees Celsius.
Container Taring
Mass Standardization
A logistical procedure in export shipping establishes the empty weight of a transport vessel before loading flax bales or linen packages. The execution of container taring ensures that the subsequent gross weight measurements accurately represent the actual cargo weight without including the steel housing of the container. In international trade, this baseline measurement determines the net weight used for customs declarations and trade invoices.
Operational Execution
Weighbridges at the mill or port gates register the weight of the empty vehicle and its container before any goods are loaded. This tare value is recorded on the shipping documentation and subtracted from the total weight of the loaded vehicle. Any discrepancy in this measurement can result in financial penalties or delays during customs inspections at the importing port.
The procedure utilizes calibrated scales to prevent inaccuracies caused by fuel level changes, driver cabin contents or vehicle wear. Scales must be certified annually by local metrology authorities to maintain the validity of the recorded tare weight.
Financial Accuracy
Invoiced amounts for raw flax shipments rely directly on the net mass calculated through this subtraction. Moisture variations and packing materials already introduce variables, making an accurate tare essential for transaction security. By establishing a verified tare weight, both the spinning mill and the exporter prevent disputes regarding volume losses during transit.
