ISO tank rental cost is not a single figure. A quote for ISO tank shipping from India is made of rental or lease, positioning, cleaning, loading charges, ocean freight and port costs, and each can be quoted separately or hidden inside a lump sum. This article does not give rates. It shows what each line covers so you can compare quotes properly.
For background on the tank itself, read how ISO tank shipping and cleaning work.
What is inside an ISO tank quote?
Ask the forwarder or tank operator to break the quote into these lines, and to say which are included:
- Tank lease or rental for the trip, usually charged per day or per round trip, with a stated number of free days.
- Positioning of the empty tank from the depot to the Gujarat plant, which depends on where the nearest depot is.
- Pre-load cleaning and the cleaning certificate, which is required for the product you are loading, not a generic wash.
- Heating or steam if your product must stay above a certain temperature, and the cost of keeping it there on the voyage.
- Ocean freight, plus any dangerous goods surcharge if the product is classed under the IMDG Code.
- Port, terminal and customs handling at both ends, including export documents on the Indian side.
- Return of the empty tank, cleaning after discharge and repositioning, which many operators bill to the buyer.
What drives the cost up or down?
Three things move an ISO tank quote more than any other. The first is the product: a food-grade or high-purity chemical needs stricter cleaning and often a tank kept for that use. The second is whether the tank must come back empty to India or can be reused in the destination market. The third is time. Every extra day waiting at the plant, the port or your site is charged as detention against the tank.
Tank availability also changes with the season and trade direction. A quote that was open for weeks may not hold, so ask how long it is valid and what happens when it lapses. A real quote for your product and route comes from a sourcing review, not from a table.
What is the ISO tank minimum quantity?
A standard 20-foot ISO tank typically holds somewhere between 20 and 26 cubic metres, so the quantity is a full tank load rather than a pallet count. The weight in tonnes depends on the density of your product, and the legal payload is also limited by the tank rating and road weight limits at origin.
Liquids in tanks are normally filled to at least about 80% of capacity, or kept very low, to avoid the load surging in transit. In practice that means a partly filled tank is often not allowed, so your minimum is close to a full tank. If your demand is smaller, compare flexitanks for chemicals or drums and IBCs, which suit smaller lots.
Questions that expose a thin quote
Chemical freight also takes different time to different markets; our note on chemical freight time to Europe and the US helps you plan the free days.
- How many free days are included at the plant, at the port and at my site, and what is the daily charge after that?
- Who owns or leases the tank, and who is responsible if it is returned dirty or damaged?
- Is the cleaning certificate specific to my product, and who issues it?
- Is the dangerous goods surcharge included, and does the shipping line accept my product on this service?
- Who pays to return and reposition the empty tank?
