Modernizing Metal Scrap Recycling: Container Seals, Moisture Losses & Weight Bridge Reconciliation

The global scrap metal trading and recycling industry handles millions of metric tons of ferrous and non-ferrous scrap annually—ranging from ISRI grade Heavy Melting Scrap (HMS 1&2), shredded scrap, copper wire (Birch/Cliff), to aluminum turnings and brass honey scrap.

1. The Complexity of Scrap Metal Logistics

Unlike standard packaged goods where purchase orders equal received inventory 1-to-1, scrap metal shipments are inherently variable. A typical container ship transporting scrap metal across international waters encounters several physical operational challenges:

• Moisture & Dross Deductions: Turnings, borings, and uncleaned cast scrap carry residual oil and moisture, requiring gross-to-net weight adjustments during inward weighbridge gate-in.
• Container Seal Verification: Ensuring container seal numbers on the Bill of Lading match physical customs seals on arrival to prevent cargo theft or substitution.
• Weighbridge Variance: Discrepancies between load-port draft surveys / supplier invoice weights versus destination weighbridge scale slips.

2. Automating Yard Gate-In and Inspection Reports

To eliminate manual errors and ensure complete traceability, modern recycling facilities deploy specialized ERP software designed for metal scrap. When a container enters the recycling yard or warehouse:

1. Gross Weight Slip Generation: Integrated weighbridge software captures container truck gross weight automatically via serial sensor inputs.
2. Quality Inspection & Grade Classification: Inspectors record ISRI code classifications, attachment percentages (e.g., rubber, plastic, moisture), and capture photo evidence.
3. Tare Weight & Net Weight Computation: After un-stuffing, the empty container truck is re-weighed to determine net scrap payload.

3. Financial Accounting & Cost per Ton Valuation

In scrap metal trading, profitability is determined at the landed cost level. Landed cost includes purchase price, ocean freight, terminal handling charges (THC), custom duty, clearing agent charges, inland transportation, and weighbridge fees. FAS26 automatically allocates landed expenses across individual shipment lines to produce true net cost per metric ton.
