NMFC 36540 - Roof Flashing, Copper/Zinc | Class N/A

To find the correct freight class for your shipment:

1. Pack flashing, flanges, and rainproofs in rigid boxes or wood crates with edge guards and interleaving sheets (kraft or VCI) to prevent dents and surface rub on soft copper or zinc.
2. Add moisture protection: line cartons/crates with poly, use desiccant, and avoid treated lumber contacting bare copper to prevent staining during long LTL transits.
3. State the materials and packaging on the BOL, for example: “Roof flashing/flanges, copper or zinc, boxed/crated — NMFC 36540 (see Note, item 35932).” Include piece count and longest length.
4. Brace long runs so they won’t bow. Strap to a plywood backer, mark “Do Not Bend,” and ship on skids sized for forklift tines to avoid punctures and handling claims.

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

• Accurate NMFC 36540 use and boxed/crated packaging lowers reclass risk, protecting your freight rates and preventing surprise invoice adjustments.
• Non-hazardous status simplifies compliance and eliminates hazmat fees, accelerating pickups and reducing administrative overhead.
• Damage-resistant packing (edge protection, bracing, VCI) reduces claims on malleable metals, preserving finish quality for roofing distributors and installers.
• Right-sized crates improve cube utilization and handling, helping you avoid oversize surcharges on long flashing runs and keeping LTL costs predictable.
