How to Determine Your Class
To find the correct freight class for your shipment:
- Verify the product is a rigid guard or grille for doors, windows, or skylights made of iron or steel bar/plate—not woven wire—to qualify for NMFC 36640, Class 70.
- Use an A-frame or edge-crated pallet; pad corners, cap sharp ends, and wrap to protect coatings. Example: a 48x72 iron window grille strapped at two points with corner boards.
- Load panels upright to prevent bowing. Block with 2x4s and secure using steel or heavy poly strapping; add “Do Not Stack” cones for taller grilles.
- Bag brackets, anchors, and screws in a small carton and band it to the pallet. Mark the BOL: “NMFC 36640, Class 70, iron/steel grilles—non-wire.”
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Fixed Class 70 simplifies quoting and reduces reclass or rebill risk for architectural metalwork.
- Non-hazardous status avoids hazmat fees and special handling surcharges, lowering landed costs.
- Proper crating and upright loading cut damage claims from bent bars or scratched finishes, protecting project timelines.
- Explicit NMFC labeling speeds dock handling and reduces OS&D exceptions, improving LTL transit reliability.
