Wood Pellet Storage: How to Keep Pellets Dry, Safe, and Sellable
Wood pellets absorb moisture fast. Warehouse humidity, stacking limits, off-gassing, and FIFO rules for wholesale pellet storage.
Wood pellets are hygroscopic — they pull moisture from the air. A well-made A1 pellet ruined by six weeks in a damp warehouse becomes a claim you can't defend.
Warehouse conditions
- Relative humidity below 65%
- Roof and wall integrity — no leaks, no condensation
- Concrete floor with vapour barrier
- No direct contact with exterior walls
Stacking limits
Big-bags: two high maximum. Pallets of 15 kg bags: three high maximum. Overstacking crushes lower bags, generates fines, and fails re-inspection.
CO off-gassing
Fresh pellets in enclosed silos emit carbon monoxide. Every enclosed storage must be ventilated and have CO monitors before human entry. This is a documented industry fatality risk.
Stock rotation
Strict FIFO. Certified pellets have a 12-month practical shelf life in dry storage; older stock is sold first or blended into industrial-grade contracts.
Pellet Industries ships ENplus A1 and industrial biomass pellets worldwide in 15 kg bags, big-bags, and bulk vessel loads.
