How to Determine Your Class

To find the correct freight class for your shipment:

  1. Determine density for each handling unit: measure the boxed length, width, and height in inches, convert to cubic feet, then divide total weight. Example: 36×24×18 in at 80 lb ≈ 9.0 cu ft, 8.9 pcf.
  2. Package to protect fragile bulbs and threads: use factory caps, molded trays or foam, double-wall cartons, and void fill that won’t crush. Mark This Side Up and Fragile on each box.
  3. Palletize with stability in mind: keep boxes within the pallet footprint, add corner boards and a top pad, stretch wrap securely, and avoid top-stacking with heavy freight.
  4. Document clearly on the BOL: “NMFC 178090 Sprinklers, in boxes,” include actual weight, calculated density (pcf), and selected class; note Subject to Item 170 and review Note, item 178091 for any exceptions.

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

Business Value

  • Density-based pricing rewards efficient packing; denser boxed heads and components can qualify for lower classes and reduced LTL spend.
  • Accurate NMFC and density entries prevent reclass/reweigh fees, cut billing disputes, and keep deliveries on schedule for jobsite installs.
  • Robust carton and pallet protection reduces breakage of glass bulbs and fittings, lowering claim rates and avoiding costly reships.
  • Non-hazardous status broadens carrier options and simplifies routing, supporting faster tendering and competitive rate shopping.
