Notes
Note 137391: NOTE-Mirrors must be protected by packing forms or other packaging materials necessary to afford adequate protection against damage.
How to Determine Your Class
To find the correct freight class for your shipment:
- Confirm the product is a mirror shipped in a closed box; this NOI item applies to boxed mirrors only. If crated or loose, choose a different NMFC.
- Measure the outer box (L×W×H in inches) and weigh it. Compute density: weight ÷ (L×W×H ÷ 1728). Use that density to select the class between 110–500.
- Review Notes items 79022 and 137391 for required packaging details and any exceptions (e.g., framing, multiple pieces, separators). Use rigid cartons, corner/edge protection, and glass-safe cushioning.
- For tall or heavy boxes, palletize upright against a support, then stretch wrap and band within the pallet footprint. Mark boxes “Glass/Mirror,” “Fragile,” and orientation arrows to reduce handling risks.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate density entry minimizes reclass/reweigh disputes and unexpected freight rate increases.
- Optimized packaging that reduces void space can raise density, often achieving a lower-cost class within the 110–500 range without compromising protection.
- Proper boxing and palletizing lower breakage and OS&D claims, cutting replacement costs and service delays.
- Non-hazardous status broadens carrier options and simplifies scheduling, often speeding up transit and pickup windows.
