Notes
Note 23701: NOTE-Corners, edges and sides of articles must be protected by interior packing forms necessary to afford adequate protection against damage from the normal rigors of the less-than-truckload environment.
How to Determine Your Class
To find the correct freight class for your shipment:
- Measure outside dimensions and weight of each box or crate, then calculate density (lb per cubic ft) to place the freight within class 85–400. Example: 48x36x2 in at 18 lb = 2.0 cu ft, 9 PCF.
- Match packaging to the board type: double‑wall cartons with rigid foam for standard markerboards; wood crates or Package 2532 for porcelain‑on‑steel or glass whiteboards and oversized chalkboards.
- Shield edges and faces with corner protectors, honeycomb edge guards, and foam sheets; separate hardware/markers in a small inner carton to prevent surface scuffs.
- Palletize upright on an A‑frame or vertical crate, band and stretch‑wrap, mark Do Not Lay Flat, and avoid pallet overhang to reduce fork and crush damage.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate density calculations can reduce the freight class and lower LTL rates, avoiding unnecessary high‑class charges for light, bulky boards.
- Spec‑grade packaging (boxes, crates, or Package 2532) minimizes breakage and OS&D claims on fragile porcelain or glass boards, cutting replacement and reship costs.
- Clear labeling and standard prep speed carrier handling and cut the risk of reclass or inspections, improving on‑time performance.
- Smart consolidation—bundling multiple boards with slip sheets and edge guards—improves cube utilization and decreases cost per board on a single skid.
