NMFC 50233 - Iron/Steel Fluxing Compounds | Class 55

To find the correct freight class for your shipment:

1. Use sturdy corrugated boxes first choice; line with poly to prevent moisture pickup and dusting. For powders, double‑bag inside cartons and seal seams with tape.
2. Declare the item as “Compounds, iron or steel, fluxing or purifying, NOI – NMFC 50233” on the BOL. Attach the SDS if available and note non‑hazardous status.
3. Weigh each handling unit accurately; this commodity is weight‑rated at Class 55. Palletize cartons, band tightly, and stretch‑wrap with a top sheet to control spillage.
4. Keep dry and away from humidity to avoid caking or clumping. Example: foundry shipments of 2,000 lb on a palletized stack of boxed product with corner boards for stability.

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

• Class 55 delivers favorable cost per pound, helping foundries, mills, and galvanizers lower LTL spend on routine replenishments.
• Non‑hazardous designation avoids hazmat surcharges and carrier limitations, simplifying carrier selection and booking.
• Packaging in compliant boxes reduces risk of reclass, inspections, and loss/damage claims, protecting margins and service levels.
• Clear NMFC coding speeds quoting and auditing, enabling predictable freight rates for recurring industrial commodity flows.
