NMFC 179460 - Clay/Graphite Stopperheads | Class 55

To find the correct freight class for your shipment:

1. Write the commodity as “Stopperheads or Sleeves, clay and graphite combined” and show NMFC 179460, Class 55 on the BOL; no density entry is needed.
2. Use rugged packaging: double‑wall boxes or wood crates with end caps on each sleeve, foam or corrugated dividers between pieces, and void fill to prevent chipping. Drums should be lined and layered with separators.
3. Palletize low and secure: center heavy boxes/crates on the pallet, band with steel or heavy poly strapping, add corner boards, and limit stack height to prevent crush damage.
4. Control dust and keep dry: bag components or wrap bundles to contain graphite residue and protect labels; moisture protection helps packaging integrity during transit.

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

• Fixed Class 55 simplifies quoting and prevents costly reclass or reweigh disputes—no density calculations or dimension-based rating adjustments.
• Economical LTL linehaul for dense refractory pieces, improving cost per pound compared to higher-class listings.
• Non-hazardous status avoids hazmat surcharges and broadens carrier options, reducing accessorial risk.
• Standardized packing in boxes, crates, or drums reduces transit damage and claims, stabilizing total landed cost.
