Classification Details

NMFC Description Class
188330.00 Valves, thermostatic (Thermostats), internal combustion engine coolant temperature regulating, other than salt water cooling system type, metal, in boxes:
188330.01 Blister packed or card mounted 100
188330.02 Other than blister packed or card mounted 70

How to Determine Your Class

To find the correct freight class for your shipment:

  1. Verify fit: NMFC 188330 applies to metal thermostatic valves for internal combustion engine coolant regulation shipped in boxes; salt-water cooling types are excluded.
  2. Protect the sensing element: wrap each thermostat with VCI paper, add cell dividers or molded trays to immobilize stems; use double-wall 200–275# cartons. Example: 24 units in a 16x12x10 box with a pulp grid.
  3. Palletize for LTL: keep boxes under 40 lb, stack evenly on 48x40 pallets, add edge protectors and two straps, and label “Boxed Metal Parts – Do Not Crush.”
  4. Document clearly: list part numbers and quantities per carton, mark “NMFC 188330, Class 70–100,” and ensure parts are clean and dry with no coolant residue.

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

Business Value

  • Predictable rating within Class 70–100 stabilizes LTL quotes and reduces reclass risk when shipped in boxes as specified.
  • Non-hazardous component avoids hazmat surcharges and accelerates carrier acceptance and tendering.
  • Boxed, protected packing lowers claims on delicate wax-pellet thermostats, preserving warranty costs and customer satisfaction.
  • Dense, compact metal parts cube efficiently; consolidating small boxes into master cartons improves throughput and minimizes minimum-charge exposures.
