Key Shipping Risks for Gravel
Be aware of these 4 common risks when booking LTL freight.
- !Gravel: Weight limit violations due to high material density causing frequent carrier adjustments and overcharge penalties.
- !Gravel: Contamination of cargo during transit from foreign debris or moisture affecting moisture-sensitive construction project requirements.
- !Gravel: Packaging failure from aggregate abrasion, leading to pallet integrity loss and potential load shift during transit.
- !Gravel: NMFC reclassification risks if moisture absorption significantly alters the declared shipment density during the shipping cycle.
Packaging Requirements (4 Steps)
Follow these steps exactly to avoid reclassification fees and damage claims.
- 1For safe Gravel transport: Utilize industrial-grade 5-mil poly-lined bulk bags to prevent sifting and moisture ingress during transport.
- 2For safe Gravel transport: Secure bulk bags onto heavy-duty heat-treated wood pallets using high-tension, UV-resistant polyester strapping.
- 3For safe Gravel transport: Apply dual-layer stretch wrap with an anti-slip top sheet to stabilize the load and prevent movement.
- 4For safe Gravel transport: Attach high-visibility weather-resistant placards to all four sides of the pallet for safe handling identification.
