Key Shipping Risks for Lumber
Be aware of these 4 common risks when booking LTL freight.
- !Lumber: Moisture absorption causing warping, rot, or mold growth during transit in non-climate-controlled trailers.
- !Lumber: Physical damage from forklift tines puncturing bundles or crushing edges during cross-dock operations.
- !Lumber: Banding failure resulting in load shifting, creating safety hazards and potential structural damage.
- !Lumber: Reclassification disputes due to inaccurate density reporting if dimensions are not calculated after wrapping.
Packaging Requirements (4 Steps)
Follow these steps exactly to avoid reclassification fees and damage claims.
- 1For safe Lumber transport: Bundle materials tightly using heavy-duty steel or polyester strapping at 24-inch intervals along the length.
- 2For safe Lumber transport: Wrap bundles in moisture-resistant, UV-stabilized plastic stretch film to protect against environmental contaminants.
- 3For safe Lumber transport: Utilize heat-treated wood dunnage beneath bundles to ensure 4-inch forklift entry clearance for mechanical handling.
- 4For safe Lumber transport: Apply high-visibility labels on all four sides indicating weight, bundle dimensions, and 'Do Not Stack' warnings.
