NMFC 36970 - Ridge Roll, iron/steel/tin | Class N/A

To find the correct freight class for your shipment:

1. Bundle long ridge roll sections with edge guards and end caps, then strap to a skid; add VCI paper for galvanized/tin plate to prevent moisture staining.
2. Disclose true length and request long-freight handling if over 8–12 ft; expect overlength fees and avoid cantilevered overhang during pickup.
3. Nest profiles face-to-face to reduce denting, and block with wood cradles so pieces do not roll; mark Do Not Stack over delicate finishes.
4. On paperwork, cite NMFC 36970 and Note item 35932, list material (iron, steel, or tin plate), bundle count, dimensions, and accurate weight for rating.

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

• Correct NMFC (36970) and Note 35932 references cut reclass/rebill risk and stabilize LTL rates.
• Non-hazardous status widens carrier options and shortens tender-to-pickup time.
• Optimized bundling on skids reduces transit damage and claims, protecting margins on roofing projects.
• Transparent length disclosure controls overlength surcharges upfront and improves quote accuracy for contractors and distributors.
