Logistics & Transport Recommendations

Pallet Packaging Rule

Safe stacking limit: 39 pieces per pallet to stay within the 2,500 lbs standard wood pallet rating.

NMFC Item Guidance

Reference code: 112000 (Fiberboard Pressed). Rated under Class 55 based on 48 PCF density.

  • Shipment utilizes 0.7% of a standard 53ft trailer's 45,000 lbs legal cargo payload (44,680 lbs capacity remaining).
  • Standard GMA pallet recommendation: Maximum 39 units per pallet to remain within the 2,500 lbs safe working limit.

Shipping, Packaging & Stacking Specifications for MDF Board

Transport & Palletizing Rules

Significantly heavier than solid pine or plywood. A single 4x8 ft 3/4" sheet weighs ~96 lbs.

Typical Industrial Applications
  • Cabinet doors & trim
  • Speaker enclosures
  • Flat-pack furniture (IKEA style)
  • Decorative wall moldings
Critical Handling Cautions:
  • Extreme susceptibility to water swelling; edge swells up to 50% if exposed to wet trailer floors
Material density and metallurgical weight benchmarks correspond to standard test specifications from ASTM International and density rating tables from NMFTA.
