Notes
Note 50166: NOTE-Applies on compounds that trap or absorb dry or liquid waste from hard surfaces or bodies of water. Does not apply on chemical or oil absorption booms, pads, sweeps or other forms or shapes, as named in item 149265.
How to Determine Your Class
To find the correct freight class for your shipment:
- Confirm the product is a non-disinfectant absorbent or floor sweeping compound; disinfectant-treated blends are classified differently (see item note 50166).
- Calculate density per palletized unit to select class: weigh the shipment, measure the overall cube (including pallet), and compute pounds per cubic foot to map to Item 170.
- Choose sturdy packaging: double‑wall corrugated boxes with poly liners for fine granules (diatomaceous earth, clay); use drum liners or heavy bags for higher-moisture products.
- Palletize to contain dust and prevent leaks: use corner boards, full wrap, and a top sheet; mark “Absorbent Compound – Non-Hazardous” and keep loads dry during transit.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Density-driven rating enables real savings: documenting higher PCF products (e.g., clay-based) can move loads to lower classes and reduce LTL rates.
- Non-hazardous status streamlines carrier acceptance and avoids hazmat surcharges, documentation time, and special handling fees.
- Proper liners and reinforced boxes cut spill claims and clean-up accessorials, protecting margins and customer relationships.
- Maintaining SKU-level density records speeds quoting, prevents reclass/rebill disputes, and standardizes costs across plants and job sites.
