Classification Details

NMFC Description Class
40730.00 Carbon Dioxide, solidified (Dry Ice), in boxes or insulated blanket skids 70

How to Determine Your Class

To find the correct freight class for your shipment:

  1. Note NMFC 40730 and Class 70 on the BOL, and specify the package type—boxed insulated shipper or insulated blanket skid. Include gross weight; density isn’t required.
  2. Pack with vented, double‑wall cartons and foam/EPS liners; never seal airtight. For blanket skids, use breathable insulated blankets, cornerboards, and two-way strapping with slight airflow gaps.
  3. Plan short transits to offset sublimation. Choose guaranteed or expedited LTL and avoid weekend layovers; add Do Not Stack on tall insulated shippers as needed.
  4. Label “Dry Ice (Solid CO2)” and apply orientation/venting notices. Keep away from live animals and enclosed cabs; request storage in ventilated terminal areas.

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

  • Flexible packaging—boxes or insulated blanket skids—supports food, pharma, and lab cold‑chain moves with fewer temperature excursions.
  • Predictable rating streamlines quoting and TMS automation, speeding tenders and improving lane planning.
