NMFC 168400 - Railcar Truck Frames or Sides | Class 50

To find the correct freight class for your shipment:

1. Package on welded cradles or heavy hardwood dunnage, then steel-band tightly; add clear lift points so forklifts don’t deform flanges or web sections.
2. List the description precisely on the BOL: “Truck Frames or Sides, railway car or locomotive, steel — NMFC 168400 — Class 50” to prevent reclass fees.
3. Plan for length: pieces over 8–12 ft may trigger LTL over-length charges; use volume LTL or flatbed when sections are especially long or uneven.
4. Shield critical surfaces: cap bolt holes, cover machined pads with VCI paper and edge guards, and use absorbent wrap to prevent oil transfer onto other freight.

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

• Predictable pricing with a fixed Class 50—no density calculations, faster quotes, and fewer rating disputes.
• Lower landed cost for heavy steel components compared to higher classes, especially on dense, rigid frames.
• Reduced risk of carrier reclass and accessorials by using the exact NMFC wording and planning for length surcharges upfront.
• Better claims performance through purpose-built cradles and surface protection, minimizing transit damage and downtime for railcar rebuilds.
