NMFC 34320 - Mine Doors, Automatic KD | Class 85

To find the correct freight class for your shipment:

1. List each component on the BOL—door panels, steel frames, automatic actuators, controls, and hardware—under NMFC 34320, Class 85 for clean rating and quoting.
2. Pack KD panels flat on pallets with corner protection; block and band frames so they cannot roll. Cushion sensor heads and control boxes in labeled inner cartons.
3. Keep fixtures and fasteners bagged by door set to avoid mixing on multi-door shipments. Example: carton label “Door Set A – hinges, closers, anchors.”
4. Use moisture-resistant wrap or VCI paper for steel parts that will be installed underground, and mark crates “Do Not Stack” if frames exceed panel strength.

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

• Predictable pricing with fixed Class 85—no density calculations or reclass hassles for KD mine door sets.
• Cleaner receiving and fewer claims by shipping frames, panels, and automatic fixtures knocked down and individually protected.
• Faster quoting and scheduling for mine contractors and OEMs using a single NMFC item across varied packaging (crates, bundles, pallets).
• Accurate classification reduces unexpected accessorials and reweigh fees, improving margins on project bids and maintenance contracts.
