NMFC 141140 - Clay Nozzles, Sleeves, Stoppers | Class 50

To find the correct freight class for your shipment:

1. List the commodity as “Clay nozzles/sleeves/stopper heads, NMFC 141140, Class 50” and choose boxes, crates, or drums to match your packing method.
2. Use dividers, foam, or corrugated cells to keep pieces from touching; edge chipping is common on brittle clay parts during LTL vibration.
3. Crate heavier sets with blocked corners and strap to a pallet; mark top-load orientation and avoid stacking on fragile refractory faces.
4. For drum shipments, line with heavy poly and add honeycomb partitions; include a piece count and packing slip on the exterior for quick inspection.

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

• Fixed Class 50 eliminates density calculations, speeding quotes and preventing reclass fees for these clay components.
• Non-hazardous status broadens carrier options and lowers compliance overhead compared to regulated materials.
• Damage reduction through proper boxing/crating minimizes claims on brittle refractory parts, protecting project timelines at foundries and glass plants.
• Consistent coding under NMFC 141140 improves rate predictability across lanes, aiding budget planning for recurring releases and contract freight.
