Packaging Allowance
Receiving logs at flax spinning mills record gross intake weights alongside tare deductions to isolate true fiber mass from transport packaging. A dry weight tare adjustment subtracts the verified weight of steel strapping and plastic wrapping from gross bale weight before moisture testing begins. Mill intake protocols mandate weighing packaging materials across representative sample bales to establish accurate tare ratios for entire shipments.
Final weighment certificates cite these net figures as the basis for commercial settlement and internal yield tracking.
Mass Calculation
Scale operators weigh individual incoming bales upon arrival at the raw fiber warehouse to determine total gross mass. The dry weight tare adjustment applies either actual tare values obtained by stripping and weighing packaging from five percent of bales or agreed standard tare allowances specified in supply contracts. If a twenty-ton shipment contains one hundred bales with an average packaging mass of two point five kilograms per bale, total tare deduction equals two hundred fifty kilograms.
Subtracting this packaging mass yields the true dry net weight used in moisture content calculations and inventory accounting. Mill laboratory reports log these corrected figures on commercial receipt vouchers signed by logistics supervisors.
Deduction Limit
Tare calculations stop governing shipment mass once raw fiber bales are unstrapped and fed into opening machinery. Dry weight tare adjustment operates strictly during initial receiving inspection and commercial invoice verification.
