NMFC 36310 - Steel Fire Doors, Mineral Filled | Class 70

To find the correct freight class for your shipment:

1. List on the BOL as “Doors, fire, steel, mineral/asbestos core — NMFC 36310, Class 70, non-haz” to prevent reclass and billing disputes.
2. Palletize or crate door leaves flat with rigid corner protection and blocking; keep banding off door faces to avoid bowing and skin damage.
3. Separate loose hardware and labels from the leaves, wrapping hinges and closers so metal edges don’t mar factory finishes during LTL handling.
4. Confirm site needs (jobsite access, liftgate, delivery window). Construction projects often require appointment delivery and no-stacking instructions.

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

• Fixed Class 70 delivers predictable rating, reducing reweigh/reclass fees and keeping quotes consistent across repeated project shipments.
• Non-hazardous status broadens carrier options and avoids hazmat surcharges, improving lane coverage to active jobsites.
• Proper crating and flat, secured palletization cut damage risk on heavy steel leaves, lowering claims and downtime on installations.
• Clear NMFC identification speeds terminal handling and billing, shortening transit exceptions and helping GC schedules stay on track.
