NMFC 193100 - Vehicle Parts in Boxes | Class by Density

To find the correct freight class for your shipment:

1. Confirm the commodity fits the scope: bicycle components, hitches/couplers, freight trailer parts, and lift truck attachments—not whole vehicles or engines with fluids.
2. Pick packaging by part type: double‑wall boxes with dividers for small hardware; wood crates for heavy or irregular attachments. Pad sharp edges and follow Item 170 standards.
3. Calculate density after packing: measure outside L×W×H in inches, convert to cubic feet (÷1728), then weight ÷ cubic feet = PCF. Example: 180 lb in 8.0 cu ft = 22.5 PCF.
4. State it cleanly on the BOL: “NMFC 193100 Vehicle Parts, NOI, boxed/crated, density 22.5 PCF,” include piece count and palletization to ensure the correct density class is applied.

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

• Optimize density to target a lower freight class, directly reducing LTL base rates on boxed or crated parts.
• Item 170‑compliant boxes/crates curb reclass inspections and damage claims, lowering avoidable fees and delays.
• Clear labeling (NMFC, packaging, PCF) speeds terminal handling and minimizes OS&D, improving on‑time performance.
• Non‑haz category broadens carrier options and avoids hazmat surcharges, simplifying quotes and procurement.
