NMFC 121570 - Air/Liquid/Pressure Sensors | Class 100

To find the correct freight class for your shipment:

1. Use rigid boxes with dense foam to immobilize gauges and transmitters; cap all pressure ports and protect dial faces or probes with guards.
2. For carton-in-crate jobs, anchor the inner carton with blocking and braces so sensitive instruments (e.g., temperature controllers) can’t shift in transit.
3. When using protective shipping drums, suspend the device with inserts; avoid over-tightened bands and mark orientation for liquid-filled gauges.
4. Palletize boxes or drums on 4-way pallets with no overhang; add corner boards and show NMFC 121570, Class 100 on the BOL to prevent reclass.

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

• Predictable LTL pricing at fixed Class 100, simplifying quotes and budgeting for instrumentation moves.
• No density-based class shifts—correct packaging (box, drum, or crated carton) keeps the shipment aligned with the NMFC rule.
• Lower reclass and claim risk when you match the described packaging, improving carrier acceptance and cycle times.
• Covers cross-industry instruments (auto, HVAC, process control), letting teams consolidate under one NMFC for cleaner routing and billing.
