NMFC 18520 - Car & Truck Exterior Doors | Class N/A

Note 18524: NOTE-Loose provisions only apply on doors or rear deck lids not glazed, covered with not to exceed one coat of protective coating or prime coating, without handles, trim or other external attachments.

To find the correct freight class for your shipment:

1. Protect the finish and glass: wrap painted surfaces with foam, add corner guards, and pad window openings. If possible, remove loose trim and bag hardware.
2. Stabilize on a pallet or in a light crate: stand doors upright with soft straps and blocking. Use double-wall corrugated or a wood frame to prevent bending.
3. Mark paperwork clearly: list “NMFC 18520 – Exterior Doors, NOI (see item 18262)” on the BOL, note non-hazmat status, and include piece count and packaging type.
4. Measure including hinges, handles, and latch protrusions. For multiple doors or tailgates, separate layers with honeycomb board and cap with a rigid top sheet.

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

• Accurate NMFC usage reduces reclass fees and surprise adjustments, improving quote-to-invoice accuracy on auto body panels.
• Damage mitigation from proper crating and edge protection lowers claim risk and expensive repaint or refinish costs.
• Unit cost drops when pairing two doors or a door plus tailgate on one pallet, helping hit better LTL rate breaks.
• Clear labeling and orientation instructions speed cross-dock handling, helping meet collision shop and dealer deadlines.
