NMFC 33570 - Misc. Building Materials | Class N/A

To find the correct freight class for your shipment:

1. Pin down the exact product and form—bagged mortar mix, concrete pavers, rolled underlayment, or mixed construction pieces—before quoting or tendering.
2. Match packaging to the material: poly-lined bags for powders, tight shrink wrap and banding for bricks or pavers, corner boards and top sheets to shield abrasive edges.
3. When combining SKUs, build segregated tiers by weight and hardness, label each layer, and list NMFC 33570 plus clear item descriptions on the BOL.
4. If a dedicated NMFC item exists for your material, use it; otherwise reference this grouping and provide dimensions and weight if requested to avoid reclass.

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

• Faster rate discovery when the exact material code is unclear, reducing back-and-forth and accelerating quotes.
• Lower risk of reclass and surprise charges through precise descriptions and packaging aligned to building-material handling.
• Fewer damage claims by unitizing heavy, abrasive products correctly, cutting touch points and edge impact.
• Better trailer utilization by palletizing dense items compactly, helping control LTL spend on mixed construction loads.
