NMFC 143750 – Steel Thread Protectors | Class 55

To find the correct freight class for your shipment:

1. Package iron/steel box and pin protectors in sturdy corrugated boxes or wire them into tight, manageable bundles (e.g., 25–50 pieces by size) to prevent abrasion.
2. Palletize boxes and wired bundles with edge protectors and steel or poly banding; no overhang, and stretch-wrap to keep loose protectors from shifting.
3. Mark by size and type for yard crews: e.g., “3-1/2 in. Pin Protectors – 100 pcs, Steel,” which speeds oilfield receiving and count verification.
4. Select NMFC 143750 at Class 55 and choose the correct packaging description (boxes or wired together) to avoid reclass or inspection delays.

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

• Fixed Class 55 delivers predictable LTL pricing for dense steel components, often beating higher-class metal hardware rates.
• Non-hazardous status removes hazmat fees and paperwork, accelerating booking and dock turns.
• Clear packaging language (boxed or wired together) aligns with NMFC wording, reducing reclass risk and carrier disputes.
• Efficient cube: stackable boxes or compact wired bundles let you consolidate more protectors per pallet, cutting handling and minimum charges.
