NMFC 90340 – Roofing Slate | Class N/A

To find the correct freight class for your shipment:

1. Reference NMFC 90340 on the BOL and describe the commodity as roofing slate; note packaging form (pallets or wood crates) and include accurate piece counts.
2. Palletize tightly with edge protectors, top caps, and steel or polyester banding; prevent overhang and use 4-way pallets rated for the slate’s weight.
3. Avoid double-stacking; block and brace inside trailers, or request tarps for open-deck moves to keep packaging intact and minimize chafing.
4. Mark shipments as fragile stone and non-hazardous; provide actual weights and photos during quoting to reduce inspections and speed carrier approval.

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

• Correct commodity entry (NMFC 90340) helps prevent reclass fees and accelerates pricing since no density-based class is published.
• Proper crating or palletizing reduces breakage on brittle stone, lowering claims and returns while protecting project timelines.
• Clear packaging details (pallet vs crate, counts, weight) enable better carrier selection and can cut accessorials like rehandling or refusal.
• Using carriers familiar with stone freight improves handling at cross-docks, reducing dwell time and delivering steadier transit performance.
