Classification Details
| NMFC | Description | Class |
|---|---|---|
| 186980.00 | Towbars or Towbar Assemblies, aircraft ground towing or towing and steering combined, not self-propelled, with or without wheels, subject to Item 170 and having a density in pounds per cubic foot of: | |
| 186980.01 | Less than 9 | 200 |
| 186980.02 | 9 or greater | 100 |
How to Determine Your Class
To find the correct freight class for your shipment:
- Verify density before booking: record total weight and cubic feet for each packaged towbar or assembly to select the correct class within 100–200 (e.g., 320 lb on 28 cu ft ≈ 11.4 pcf).
- Package for point-load protection: cap tow eyes, protect steering links, and block or remove small wheels; band the tube to a skid with cradle blocks so forks don’t crush the barrel.
- Reduce overlength charges where possible: diagonal-pack the tube in a crate or detach the tow head to shrink longest side, then re-measure cubic feet for accurate density.
- Document clearly on the BOL: list NMFC 186980, note “not self-propelled” and “with/without wheels,” include weight and calculated density, and add handling notes like “Do Not Fork Under Tube.”
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate density can drop the freight class toward 100, lowering LTL rates and minimizing reclass fees for long, tubular GSE components.
- Purposeful crating and blocking protect precision tow heads and lugs, reducing damage claims, turnaround delays, and downtime for flight-line operations.
- Clear NMFC labeling (186980) and Item 170-compliant packaging speed carrier inspections and help avoid unexpected accessorials or holdovers.
- Non-hazardous status broadens carrier options and simplifies paperwork, enabling faster quotes and easier scheduling for maintenance windows.
