NMFC 114640 - Iron Grinding Balls in Boxes | Class 50

To find the correct freight class for your shipment:

1. Pack iron grinding/crushing balls in rugged corrugated boxes, lined or bagged inside the box to contain fines, then secure to a 48x40 pallet with bands and stretch wrap.
2. Keep unit weights reasonable for LTL—e.g., 1,800–2,200 lb per pallet with 40–60 lb boxes—to prevent carton failure and make forklift handling safe.
3. Distribute weight evenly; place heaviest boxes at the base and avoid overhanging. Mark pallets 'Heavy—Do Not Top Stack' if boxes are near crush limits.
4. Use the fixed NMFC 114640 Class 50 on paperwork. Describe contents as 'iron grinding balls, boxed' to prevent misclassification as bearings or bulk scrap.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Class 50 keeps LTL rates low for this dense product, cutting per-pound shipping costs on repetitive mill and mining replenishment orders.
• Non-hazardous status eliminates hazmat accessorials and simplifies carrier selection, widening your carrier pool and reducing transit variability.
• Simple, single-class rule reduces reclass fees and invoice disputes—fewer back-end corrections and faster quote-to-book cycles for procurement teams.
• Optimized palletization (tight cube, stable weight) raises damage-free delivery and lowers claims, avoiding costly downtime at cement or ore processing sites.
