NMFC 91700 - Rough-Bored Gun Barrel Tubes | Class 85

To find the correct freight class for your shipment:

1. Use double‑wall boxes with internal blocking so each tube can’t roll; add end caps or foam plugs to protect the bore.
2. Line boxes with VCI paper or oil‑resistant wrap if tubes are lightly coated after rough boring, preventing staining and moisture.
3. Distribute weight evenly; for multiple tubes, separate with wood dividers or corrugated honeycomb and mark the heavy side on the carton.
4. Unitize boxed sets on a skid for safer LTL handling; band lightly and avoid overhang to reduce crush and claim risk.

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

• Fixed Class 85 rating simplifies quoting and helps lock predictable LTL costs across carriers.
• Boxed packaging lowers handling risk versus loose tubes, reducing damage claims and rework on precision components.
• Non-hazardous status speeds tendering and broadens carrier options, improving transit flexibility.
• Clear NMFC alignment for rough-bored tubes avoids density disputes, saving audit time and accessorial surprises.
