NMFC 36640 - Iron Window Grilles | Class 70

To find the correct freight class for your shipment:

1. 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.
2. 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.
3. 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.
4. 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.

• 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.
