For dense bagged chemicals like calcium chloride, a shipping container fills up by weight long before it runs out of space. Knowing the practical payload helps you order in clean full-container-load (FCL) quantities and avoid paying to ship air. These are planning estimates — your supplier confirms exact loading for the grade, packaging, and shipping line.
The weight limit comes first
A standard 20ft container has a large internal volume but a payload cap typically in the region of 26–28 tonnes once the container's own weight and route limits are considered. Because calcium chloride is dense, you reach that weight limit while the box is only part full — so weight, not volume, sets the order size.
Typical 20ft planning figures
| Packaging | Indicative quantity per 20ft | Notes |
|---|---|---|
| 25 kg bags | ~25–27 MT | Floor-loaded or palletised |
| 50 kg bags | ~25–27 MT | Fewer handling units |
| 1 MT jumbo bags | ~20–24 MT | Faster handling; some space unused |
Palletised vs floor-loaded
- Floor-loading bags maximises payload but is slower to load and unload by hand.
- Palletising speeds handling and protects bags, but pallets consume some payload and space.
- Jumbo bags are quick to move with a forklift but leave more unused volume.
Plan around landed cost
Ordering to the container's weight limit spreads freight across the most product, lowering cost per tonne delivered. Confirm the exact MT, packaging, and whether the load is palletised or floor-loaded with your supplier before booking.
