NMFC 176620 - Sulfate Black Liquor Skimmings | Cl 50–60

To find the correct freight class for your shipment:

1. State the exact NMFC on your BOL: “Skimmings, sulfate black liquor, not acidified or otherwise processed,” NMFC 176620. Use the applicable fixed class in the 50–60 range; no density break needed.
2. Load in corrosion‑resistant closed‑head drums or IBC totes with tight bungs/valves. Palletize, band securely, add absorbent liners or trays, and keep closures upright and protected.
3. Schedule pickup while the liquor is pumpable. In cold weather, maintain moderate temperature (around 50°F or higher) to limit thickening and solids settling during transit.
4. Choose carriers comfortable with industrial liquids/byproducts. Share an SDS confirming non‑acidified, non‑hazmat status and request spill‑kit handling or no‑tip service if valves are present.

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

• Correct use of NMFC 176620 at class 50–60 minimizes reclass and inspection disputes, protecting margins and delivery timelines.
• Non‑hazardous listing broadens carrier options and avoids hazmat surcharges, documentation hurdles, and capacity constraints.
• Leak‑preventive packaging and secondary containment reduce cleanup risk, claims exposure, and costly service interruptions at terminals.
• Consolidating volume in IBCs can lower handling touches and improve per‑pound LTL rates compared with many higher‑class chemical items.
