NMFC 135950 - Metal Thermostats | Class N/A

To find the correct freight class for your shipment:

1. Identify whether you’re sending finished thermostatic controls or bare metal housings, and note any fragile capillary tubes or sensor bulbs that need protection.
2. Use inner cartons with dividers for small units and foam-lined crates for larger housings; cap and secure terminals and capillaries to prevent bending or puncture.
3. Palletize tightly with corrugated trays and stretch wrap; keep heavy metal near deck boards and add orientation arrows and “Do Not Crush” labels.
4. Write “Metal, thermostat” on the BOL with piece counts and packaging type (cartons, crates, pallets) to align with NMFC 135950 and speed carrier inspections.

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

• Precise “Metal, thermostat” description reduces reclass disputes and stabilizes LTL invoicing.
• Non-hazardous classification avoids hazmat surcharges and broadens carrier options for mixed appliance or HVAC shipments.
• Protective packing for sensor caps and capillaries lowers damage claims and keeps production lines on schedule.
• Consolidating dense metal thermostats on well-built pallets improves handling efficiency and can help qualify for better carrier rates.
