NMFC 122860: Heat Exchanger Tube Bundles | Class N/A

To find the correct freight class for your shipment:

1. Use heavy-duty boxed packaging: triple-wall corrugated or a wood-reinforced box, with foam blocking to immobilize the tube bundle and caps on all tube ends.
2. Add moisture protection for metallic cores (copper, stainless, titanium) using VCI wrap or sealed poly liners, then cushion and fill voids to prevent shifting.
3. Mark handling instructions clearly: Center of Gravity, Do Not Tip, and Keep Dry. Ensure the box orientation keeps tube sheets and fins protected from impact.
4. Provide accurate specs on the BOL: boxed packaging, exact weight and dimensions, materials, and lift points. For LTL, place the box on a sturdy pallet and band securely.

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

• Clear NMFC listing for boxed tube bundles reduces reclass disputes and keeps invoices aligned with quoted rates.
• Purpose-built boxed packaging lowers damage risk to delicate fins and tube sheets, cutting claim costs and downtime.
• Non-hazardous status simplifies carrier acceptance and eliminates hazmat fees and paperwork time.
• Consistent documentation (materials, orientation, lift points) speeds dock handling and shortens transit-related delays.
