NMFC 159530 - Stone Sink or Vanity Tops | Class N/A

Note 159532: NOTE-Provisions on cast stone apply only on products of hydraulic, masonry, mortar, natural or Portland cement, with or without sand or aggregate, or on stone dust, chips or granules combined with not to exceed 25 percent of plastic binder molded to simulate natural stone.

To find the correct freight class for your shipment:

1. Verify material fit: item 159530 applies to cast (cultured) or natural stone vanity or sink tops; confirm Note item 159532 before tendering.
2. Choose packaging by risk: use a wood crate for tops with large sink cutouts or over 80 lb; heavy-duty box with rigid corner/edge protection for lighter units.
3. Support and orient correctly: ship tops on edge with foam blocks and a rigid backer, mark Do Not Lay Flat, and add Fragile Stone labels on all sides.
4. Document dimensions and handling: record outer box/crate size and weight for quoting, and provide packing photos to reduce inspection delays or reclasses.

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

• Accurate NMFC alignment with 159530 and the referenced note curbs reclass fees and surprise rebills.
• Crating or reinforced boxing dramatically cuts breakage on brittle stone, lowering claim costs and reship expenses.
• Non-hazardous status widens carrier options and eliminates hazmat surcharges, improving lane flexibility and rates.
• Clear packaging instructions (edge shipping, no stack, fragile stone) speed cross-dock handling and protect project timelines for installers.
