NMFC 91850 - Gypsum & Gypsum Products Group | Class N/A

To find the correct freight class for your shipment:

1. Identify the exact gypsum form before rating—e.g., drywall sheets, bagged powder, or cast moldings—since each may use a different specific NMFC item within the gypsum group.
2. Protect edges and faces from crush and moisture. Example: 4x8 gypsum board stacked on a skid with corner protectors, top/bottom cover sheets, stretch wrap, and a poly moisture barrier.
3. Select packaging that matches the product: bagged powder on heat‑sealed multiwall bags and shrink‑wrapped pallets; ornate cast pieces in foam-lined crates with “Fragile/Keep Dry” and “Do Not Top Load” labels.
4. Document handling limits on the BOL (keep dry, no top load, do not clamp). Include piece count, pallet dimensions, and photos to prevent reclass or OS&D disputes.

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

• Lower damage and claims by preventing edge crush and moisture exposure—critical for fragile gypsum board and decorative castings.
• Accurate item selection within the gypsum group avoids reclass fees and preserves quoted LTL rates.
• Clear packaging and labeling reduce dock handling time and carrier exceptions, speeding pickups and deliveries.
• Consistent moisture protection prevents jobsite rejections and costly reships, stabilizing project schedules and budgets.
