How to Determine Your Class
To find the correct freight class for your shipment:
- Calculate density to set the class: measure L × W × H (in inches), convert to cubic feet, then divide weight by cubic feet. Example: a 24×24×6 in maple block at 60 lb is 2 cu ft → 30 PCF, typically mid-range within 70–125.
- Choose packaging by risk and weight: use a lined crate with blocking for heavy single blocks; use strong boxes with foam corners and edge guards for table tops to prevent face and edge bruising.
- Palletize for LTL: center the crate or boxed top on a 4‑way pallet, band and stretch-wrap, mark center-of-gravity if top-heavy, and avoid overhang to prevent reclass or damage.
- Document materials and pack type on the BOL: note “wood” or “wood-and-metal combined,” select “box” or “crate,” and list exact dims and weight so carriers apply the correct density class.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Density-driven rating lets dense hardwood blocks qualify for lower classes near 70, cutting LTL rates versus lighter, bulkier tops.
- Accurate specs for NMFC 39120 reduce reweigh/reclass fees and speed up quotes for butcher shops, meat processors, and restaurant suppliers.
- Crate/box alignment with the item’s rule lowers damage risk on edges and laminated faces, minimizing OS&D claims and reship costs.
- Clear non-hazardous status streamlines carrier acceptance and scheduling, improving on-time pickups during busy kitchen buildouts or remodels.
