NMFC 105660 — Lintels, Iron or Steel | Class 50

To find the correct freight class for your shipment:

1. Verify you’re shipping iron or steel lintels used as masonry/load-bearing supports and apply NMFC item 105660 with a fixed Class 50.
2. Bundle pieces by length with steel strapping, add hardwood dunnage between layers, and cap sharp ends to prevent punctures and abrasion.
3. Flag as long freight when lengths exceed typical pallet size; center the weight, block and brace to stop spear-like movement during LTL cross-docks.
4. Mark bundle counts and lengths clearly, and capture pre-shipment photos; with a fixed class, this documentation helps avoid reclass and claim disputes.

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

• Fixed Class 50 enables predictable quoting and often lower LTL rates compared to higher-class building materials.
• Simple, non-density rating minimizes audits and density disputes, reducing reclass fees and administrative overhead.
• Non-hazardous designation streamlines tendering and avoids hazmat surcharges, accelerating transit and lowering total cost.
• Standard steel-friendly packaging (bundles, dunnage, edge protection) speeds dock handling, cutting dwell time and damage risk.
