NMFC 184770 - Grindstones, natural stone | Class N/A

To find the correct freight class for your shipment:

1. Crate stone wheels on edge with spacers and foam blocking; never ship large wheels flat to avoid cracking under load (e.g., 18 in x 2 in wheel in wood crate).
2. For blocks or slabs, add corner guards, strap to a skid, and fill all voids with dense dunnage so the stone can’t shift during LTL handling.
3. Keep moisture away—wrap in poly and tape seams; add desiccant if routing through humid or freezing climates to prevent micro-fractures.
4. List as NMFC 184770 with precise dims and weight on the BOL; request “Do Not Top Load” and liftgate service for shop or jobsite deliveries when needed.

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

• Accurate NMFC reference reduces reclass fees and inspection delays, speeding quotes and pickup scheduling.
• Proper crating and edge-shipping for wheels slashes breakage rates, cutting claims and replacement costs.
• Clear non-hazardous status simplifies carrier selection and avoids hazmat surcharges or documentation overhead.
• Right-size mode choices—single wheel via LTL, multiple heavy blocks via volume LTL or partial TL—optimize freight spend.
