How to Determine Your Class
To find the correct freight class for your shipment:
- Quote with NMFC 70240 and Class 50; no density calculation needed. List contents as silica, quartzite, or flintstone pebbles on the BOL.
- Use rugged double‑wall cartons with a poly liner to contain fines. Close with reinforced tape and mark each box “Heavy” when over 50 lb.
- Palletize tightly: distribute weight evenly, add a slip sheet, corner boards, and top cap, then stretch‑wrap and apply two poly straps to prevent shifting.
- Control moisture and abrasion: keep boxes off the floor, avoid overfill that bulges panels, and note grain size or grade for receivers such as filtration or blasting operations.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Fixed Class 50 keeps pricing predictable and minimizes reclass fees or surprise adjustments on dense mineral shipments.
- Dense product at a low class delivers competitive cost per pound for bulk buyers in water filtration, landscaping, and foundry supply.
- Boxed pebbles are cross‑dock friendly, speeding terminal handling and reducing risk of spillage compared to loose or poorly bagged loads.
- Sturdy packaging and clear labeling reduce damage and contamination, protecting high‑value, graded media and lowering claim rates.
