NMFC 123830 - Brick-Drying Kilns | Class Density-Based

To find the correct freight class for your shipment:

1. Measure the outer box or crate (L×W×H) and weigh the packed unit, then compute density in lb/ft³ (weight ÷ cubic feet) to assign the proper Item 170 class; e.g., 1,200 lb on 64 ft³ = 18.75 pcf.
2. Crate for machinery: block and brace kiln frames, isolate burner trains and recirculation fans, protect control cabinets, and leave forklift pockets; use cross-bracing to prevent racking during LTL transfers.
3. Mark center of gravity, lift points, and “Do Not Tip.” If the kiln section is long or top-heavy, request extended forks or a liftgate and include a handling diagram for dock crews.
4. Consolidate loose parts—stacks, rails, refractory modules—inside the crate using banding and foam or VCI wrap. Add a detailed packing list with model and serial numbers for receiving.

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

• Accurate density data under Item 170 prevents reclass fees and surprise rate increases, stabilizing your kiln shipping budget.
• Purpose-built crating for kiln shells and controls reduces damage risk, cutting claims and avoiding costly production delays at brick plants.
• Clear NMFC alignment speeds quotes and approvals, improving lead times when moving equipment between OEMs, dealers, and brickyard sites.
• Selecting machinery-capable LTL carriers (with low transfer counts) improves on-time delivery and lowers handling risk for heavy kiln sections.
