| NMFC | Description | Class |
|---|---|---|
| 170510.00 | Shingles, zinc, in boxes or crates | 70 |
How to Determine Your Class
To find the correct freight class for your shipment:
- Quote Class 70 for zinc shingles when they’re boxed or crated, and mark the BOL with NMFC 170510 and non-hazmat to streamline carrier handling.
- Protect soft zinc edges: use double‑wall cartons or wood crates with corner guards, non‑acidic interleaves, and moisture wrap; example: 24‑gauge tiles boxed, banded, and palletized.
- Palletize evenly with low center of gravity; cap and strap each layer, keep total height under 48 inches, and add ‘Do Not Double Stack’ for thin interlocking profiles.
- Document piece counts per box/crate and total weight, and photograph packaging before pickup to support claim defense and speed dock checks.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Predictable costs: fixed Class 70 reduces reclass risk and delivers faster, cleaner LTL quotes.
- Lower damage exposure: rigid boxes/crates and edge protection minimize scuffs and bending on zinc surfaces, reducing replacement and labor spend.
- Operational speed: clear NMFC 170510 notation and non-hazardous status shorten inspections and cut detention or rework delays.
- Better cube and consolidation: uniform cartons/crates stack efficiently on pallets, improving trailer utilization and decreasing per‑shipment freight rates for roofing projects.
