NMFC 180840 - Air and Oil Separating, Pipeline | Class 85

To find the correct freight class for your shipment:

1. Book these inline air/oil separators as NMFC 180840 at Class 85; density does not change the rating, so quote without a density calculation.
2. Prepare units by draining oils, venting trapped air, and capping all nozzles or threaded ports. Add protective plugs and cover gauges to prevent impact damage.
3. Package on a skid or in a crate with blocking and tie-downs. Use edge guards on flanges and band to the pallet; for a 36-inch inline unit, add cradle saddles to stop rolling.
4. Mark orientation, center of gravity, and “Non-Hazmat.” Include a spec sheet noting material (steel, aluminum, or composite) and pressure rating for carrier handling notes.

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

• Predictable costs: fixed Class 85 minimizes reclasses and surprise rebills, improving quote accuracy for project bids.
• Faster tendering: no density workups mean quicker rate shopping and fewer carrier exceptions during dock audits.
• Lower claims risk: capped ports, cradled skids, and flange protection prevent leaks and flange-face damage common with pipeline tanks.
• Broader carrier options: non-hazardous status lets you use standard LTL networks and secure more competitive freight rates.
