To find the correct freight class for your shipment:

Determine density for each boxed product. Weigh the filled box, subtract tare, measure internal volume in cubic feet, then lbs ÷ ft³; higher pcf usually lowers the class within 50–400.
Use rugged packaging for abrasives and powders. Double‑wall corrugated boxes with poly liners control dust for talc or wollastonite and resist edge crush for crushed stone.
Palletize for stability. Keep boxes square, interlock layers on 40×48 pallets, add corner boards, and stretch‑wrap; cap with a top sheet to keep fines off other freight.
Describe the mineral precisely on the BOL (e.g., “Sand, NOI, boxed” or “Talc, ground, boxed”) and include NMFC 90150 and calculated density; this density item is subject to Item 170.

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

Optimize freight spend with density-based classes. Right-sizing box volume to boost pcf can move shipments to lower classes and cut LTL rates significantly.
One NMFC covers many minerals. Ship gravel, sand, slag, stone, talc, soapstone, and wollastonite under a single item, simplifying quoting and compliance across plants.
Non-hazardous status broadens carrier options. Fewer restrictions and surcharges mean faster tendering and better network coverage.
Cleaner claims profile. Sturdy boxed packaging reduces spills and abrasion damage, minimizing reclass fees, cleanup charges, and delivery delays.
