How to Determine Your Class
To find the correct freight class for your shipment:
- Confirm density: weigh the shipment and calculate cubic feet, then match the PCF to the correct class under Item 170 (e.g., heavier clay litters usually rate lower than fluffy shavings).
- Choose sturdy packaging: use heavy-duty boxes or bag-in-box with poly liners for granules or clumping products; stretch-wrap and corner-board pallets to prevent punctures.
- Control moisture and leakage: add top sheets and slip sheets, keep off damp floors, and tape seams so paper-based or wood-based bedding doesn’t wick water and gain weight.
- Document clearly on the BOL: list “Animal Litter/Bedding, bagged/boxed, NMFC 111660, density __ pcf,” include total weight and package count to avoid reweigh or reclass.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Lower freight spend by improving density (tighter pack-outs or reducing void space can shift to a lower class).
- Reduce accessorials and disputes with accurate PCF on paperwork, cutting reweigh/reclass fees and delays.
- Minimize loss and cleanup costs by preventing spillage of fine absorbents through proper liners and palletization.
- Simplify quoting and carrier selection with a predictable, density-based rating that is widely accepted and non-hazardous.
