| Material | Bulk density | Source |
|---|---|---|
| Sodium bentonite (spherical) | 0.85–1.05 g/cm³; 0.95 kg/L reference | Factory TDS (tapped method on spec table) |
| Tofu (pea fiber) | 597 g/L ≈ 0.597 kg/L | CTI third-party batch report |
| Cassava (yuca) | 600–650 g/L ≈ 0.60–0.65 kg/L | Factory TDS |
| Silica gel crystal | ≈ 0.75 kg/L | Factory TDS reference |
Why this matters: freight is paid per container, so the number of bags you actually fit decides your per-bag freight cost. Bentonite is weight-limited (the box is not full when the weight cap is hit), while tofu and cassava are volume-limited (the box fills before the weight cap). The full explanation is in our bulk density guide and the liters vs kilograms explainer.
