Note 178091: NOTE-Applies on sprinkler systems consisting of plastic or rubber hose or tubing with fittings and sprinkler heads.
How to Determine Your Class
To find the correct freight class for your shipment:
- 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.
- 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.
- 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.
- 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.
