NMFC 135530 - Calcium, metallic, in boxes | Class 100

To find the correct freight class for your shipment:

1. Book under NMFC 135530 as Class 100 with packaging listed as boxes; include piece count and weights—no density calculation needed.
2. Use rigid corrugated boxes with an inner moisture barrier (poly or foil bag) plus desiccant; seal all seams with water‑resistant tape to keep calcium dry.
3. Prevent movement and abrasion: add dividers, trays, or foam and cap sharp edges on ingots or granules to avoid puncturing liners.
4. Palletize on clean, dry pallets; full stretch‑wrap and apply “Keep Dry” and orientation labels. Avoid double‑stacking unless box burst strength supports it.

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

• Predictable pricing: fixed Class 100 simplifies LTL quotes and accelerates rate comparisons across carriers.
• Lower overhead: non‑hazardous status helps avoid hazmat paperwork, fees, and carrier restrictions.
• Fewer reclass charges: declaring packaging as boxes aligns with the item listing, reducing inspections and delays.
• Reduced claims: moisture‑controlled boxing preserves calcium integrity, cutting replacements and protecting customer relationships.
