NMFC 143290 - Carbide Steel Bit Inserts in Boxes | Class 55

Note 143291: NOTE-Applies on inserts, teeth or tips that are integral parts of rotary drilling bits having heads containing moving cutting devices.

To find the correct freight class for your shipment:

1. Enter NMFC 143290 and note “carbide steel rotary bit inserts, boxed” on the BOL; apply Class 55 to avoid reclass.
2. Individually sleeve each insert/teeth in foam or corrugated cells, add rigid dividers, and fill voids to prevent carbide edge chipping.
3. Unitize multiple boxes on a sturdy pallet with stretch wrap, corner protectors, and a top sheet to resist clamp and fork pressure.
4. Keep boxes dry and separate from oils or fluids; record piece count and net weight for accurate LTL quotes and receiving.

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

• Predictable single class (55) streamlines rating, audits, and carrier acceptance.
• Lower LTL costs than many heavy industrial parts due to favorable Class 55.
• Non-hazardous status avoids hazmat surcharges and carrier restrictions.
• Damage-mitigating packing reduces carbide chipping claims and rig downtime.
