NMFC 13090 - Alumina, calcined or hydrated | Class 55

To find the correct freight class for your shipment:

1. List the commodity on the BOL as “Alumina, calcined or hydrated, NMFC 13090, Class 55,” and note the package type used (bags, boxes, or drums).
2. Control dust and moisture: use poly‑lined bags, double‑wall boxes with liners, or tight‑ring steel/plastic drums. Palletize with interlocking layers and stretch wrap to prevent sifting.
3. Build standard 40x48 pallets where possible and keep unit weights reasonable (around 2,000 lb max) to fit LTL handling. Add corner boards and a top sheet labeled “Keep Dry.”
4. Attach or reference an SDS and mark “Non‑hazardous mineral.” This speeds carrier acceptance for shipments to ceramics, abrasives, filtration, or refinery operations.

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

• Fixed Class 55 rating removes density reclass risk, delivering predictable quotes and fewer surprise adjustments.
• Lower class versus many powders can reduce CWT rates, improving landed costs for ceramics producers, foundries, water treatment, and polishing media suppliers.
• Multiple approved packages (bags, boxes, drums) expand carrier options and reduce special handling fees or refusals.
• Accurate NMFC citation and clear packaging minimize inspections and claims, cutting admin time and chargeback exposure.
