NMFC 50239 - Magnesium Fluxing Compounds | Class 55

To find the correct freight class for your shipment:

1. State the full item on the BOL: “Compounds, magnesium metal fluxing or purifying, NMFC 50239, Class 55,” plus packaging (boxes, bags, or drums) and exact weight per pallet.
2. Keep product dry to prevent caking: place poly-lined bags in cartons or lined drums, stretch wrap tightly, and top-sheet pallets; example: 25 kg bags inside corrugated boxes on a heat-treated pallet.
3. Unitize for LTL: interlock stack cartons, add corner boards, band and wrap; keep stack height under 60 inches and mark “Keep Dry” and “Do Not Double Stack” if needed.
4. Control dust and leakage: tape carton seams, use inner liners and absorbent pads; for drums, verify ring torque and bung seals before tendering.

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

• Single Class 55 rating supports favorable LTL rates and predictable quotes for ongoing foundry and die-casting replenishment.
• Non-hazardous status avoids hazmat paperwork and surcharges, shortening pickup times and cutting accessorial risk.
• Clear labeling and proper containment minimize reclassifications and damage claims, protecting margins and delivery timelines.
• One NMFC item across boxes, bags, or drums simplifies purchasing and carrier selection, reducing administrative overhead.
