Moisture Regain between Mill Conditioning and an Unheated Warehouse
Unheated storage drives moisture ingress along sheet edges via psychrometric gradients, requiring sealed barrier wraps and strict thermal acclimation before press run.
Landed Weight Adjustment
Commercial Settlement
Financial reconciliation accounts for variations in paper shipment mass resulting from moisture absorption or loss during maritime or overland transport. The application of landed weight adjustment modifies final invoice charges based on verified delivery weights at the destination port or mill warehouse. Standard trade customs set permissible moisture deviation windows before commercial price recalculations occur.
Shipping documents state nominal ream or roll weights, but environmental exposure alters actual mass in transit.
Calculation Protocol
Freight inspectors weigh paper rolls upon discharge from transport vessels and extract core samples to measure actual moisture content. A landed weight adjustment calculates the bone dry mass of the delivery and compares it to the contractually agreed standard moisture basis. If paper arrives drier than agreed, the buyer receives a mass allowance credit, whereas excess water weight triggers an invoice reduction.
Freight contracts specify TAPPI or ISO test methods to resolve weight discrepancies between shipping ports and receiving docks. Standard accounting procedures adjust inventory valuations based on audited net dry weights.
Contractual Enforcement
International paper trade agreements stipulate clear protocols for weighing and sampling delivered shipments. Dispute resolution relies on certified independent weighmasters to verify net delivered mass. Accurate weight adjustments prevent financial losses caused by environmental moisture shifts.
