NMFC 37350 - Metal Roof/Chimney Ventilators | Class 200

To find the correct freight class for your shipment:

1. Confirm the item is a ventilator (not a chimney cap or cowl) to align with NMFC 37350 and avoid reclass fees.
2. Pack metal housings in rigid boxes or wood crates; brace collars and dampers, pad louvers, and use foam to stop flexing and denting.
3. Palletize cartons or crates, keep arrows upright, and mark Do Not Clamp to protect thin-gauge hoods and flanges from clamp-truck damage.
4. Seal against moisture with a poly bag or VCI wrap around bearings and hardware; add corner boards and edge protectors for jobsite handling.

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

• Fixed Class 200 rating simplifies quoting—no density math—speeding LTL rate shopping and tendering.
• Clear scope (ventilators only, not caps/cowls) helps prevent inspection disputes, reclass charges, and surprise rebills.
• Robust box-or-crate options cut damage risk on delicate louvers and dampers, reducing claims and jobsite delays.
• Non-hazardous status expands carrier choices and cuts compliance overhead, improving transit flexibility and cost control.
