Container capacities shown are practical loadable planning figures (20ft ≈ 28 m³ / 28,000 kg; 40ft ≈ 58 m³ / 26,500 kg; 40ft High-Cube ≈ 68 m³ / 26,500 kg), not theoretical maximums — real fit depends on carton dimensions, stacking and how the container is loaded. LCL is charged on the greater of volume (per CBM) or weight (per 1,000 kg). Always confirm with your freight forwarder before booking. Educational tool, not shipping or customs advice.
