How to Determine Your Class
To find the correct freight class for your shipment:
- Describe on the BOL: “Insulated cold storage door, boxed/crated, with/without frames, fixtures, power control mechanism” to align with the NMFC entry.
- Choose packaging: use crates when bundling frames, tracks, and operators; use heavy-duty boxes for single-panel kits. Add skids for forklift clearance.
- Protect sensitive components: brace the door leaf, guard gaskets and heaters, cap track ends, and wrap control enclosures to prevent moisture intrusion.
- Mark handling needs: center-of-gravity and lift points, Keep Upright/Do Not Stack if required, and apply tilt/shock indicators for claim-ready documentation.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate NMFC description curbs reclass fees and stabilizes LTL rates for bulky insulated doors.
- Crating with proper bracing reduces damage to heaters, gaskets, and vision panels, cutting claim costs and downtime.
- Bundling frames, fixtures, and controls in one crate streamlines site receiving and avoids installation delays from missing parts.
- Clear packaging and handling notes speed quotes and dock turns, helping secure capacity during tight build schedules.
