NMFC 122840 Heat Exchanger Cast Iron Parts | Class 77.5

Note 122842: NOTE-Applies only on one-piece castings consisting of one inner tube held within an outer tube by webs cast as a part of the one-piece casting.

To find the correct freight class for your shipment:

1. Rate and book under NMFC 122840 at Class 77.5 for cast iron heat exchanger sections, elbows, and inlet/outlet fittings—no density needed.
2. Protect brittle cast iron: cap threaded ports, cover machined faces, wrap in VCI, then block and band to a wood skid or crate to prevent impact.
3. Stabilize odd shapes like elbows with V-blocks or saddles; keep weight centered on the pallet and mark Do Not Stack to avoid fractures.
4. On paperwork, note “cast iron heat exchanger parts—non-hazmat” and reference the NMFC note (item 122842) if a carrier requests verification.

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

• Predictable pricing: fixed Class 77.5 eliminates density disputes and reduces reclass fees.
• Lower damage risk: proper bracing and crating for brittle cast iron minimizes breakage claims.
• Simplified operations: one item covers sections, elbows, and inlet/outlet fittings, easing TMS setup and team training.
• Faster tendering: non-hazardous status and straightforward class speed up quoting and carrier acceptance.
