NMFC 166850 – Railway Car Grain Doors | Class 50

To find the correct freight class for your shipment:

1. Bundle grain doors by length and type (wood or fiberboard), then strap with steel or polyester banding and corner protectors to prevent edge crush.
2. Palletize bundles with no overhang; if items exceed pallet length, use custom skids with 4-way entry blocks and top dunnage to keep stacks rigid.
3. Mark the BOL: “Grain Doors, railway car – NMFC 166850 – Class 50 – Non-hazardous,” and avoid labeling as lumber to prevent misclassification.
4. Keep material dry with a poly or kraft top sheet; moisture can warp fiberboard doors, leading to fit issues and potential claims at rail shops.

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

• Fixed Class 50 with no density rule simplifies quoting and helps keep LTL costs predictable for seasonal railcar projects.
• Single-item classification reduces paperwork complexity and cuts dispute risk versus shipping as generic lumber or mixed components.
• Proper bundling and palletizing lowers damage rates, protecting tight turnaround schedules at railcar repair facilities and grain terminals.
• Standardized labeling under NMFC 166850 speeds carrier acceptance and minimizes reweigh/reclass fees for bulk shipments of railcar doors.
