Choosing the right transport vessel for chemicals, lubricants, and fuels impacts freight costs, product integrity, and unloading logistics.
Transport Methods Compared
- Road Tankers: Best for domestic/regional transport. Carries ~36,000L. Fast turnaround.
- ISO Tanks: Reusable stainless steel cylinders inside a 20ft frame. Carries ~24,000L. Safest for hazardous chemicals. Highly multimodal (truck to rail to ship).
- Flexitanks: Single-use bladders inside standard 20ft containers. Carries ~24,000L. Cost-effective one-way transport for non-hazardous liquids (e.g., base oils).
