NMFC 34335 - Interior Revolving Doors | Class 300

Note 34336: NOTE-Applies on interior doors such as those used to access darkrooms, clean rooms or laboratories.

To find the correct freight class for your shipment:

1. Use NMFC 34335 when shipping interior revolving doors made of metal or plastic that are packaged in boxes or crates; review Note item 34336 for any scope exceptions.
2. Crate the center shaft and ceiling ring, and box the wings/panels separately with rigid edge guards and foam blocking to prevent scuffing and bending.
3. Keep the rotation axis upright. Mark “This Side Up,” “Do Not Lay Flat,” and “Do Not Spin” on each box or crate to avoid alignment damage.
4. Palletize each box or crate with no overhang, add cross‑straps, and choose a crate for preassembled sections or heavier hardware kits.

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

• Fixed Class 300 removes density debates, yielding faster quotes and fewer re-class fees for project shipments.
• Proper boxing/crating under the correct NMFC improves claim defensibility for precise alignment parts like center posts and ring assemblies.
• Consolidating accessories (push bars, canopies, trim) in the same boxed/crated line item streamlines the BOL and reduces handling charges.
• Non-hazardous designation expands carrier options and accelerates tendering for timed jobsite deliveries and rollouts.
