Some liquids cannot travel in a general-purpose T11 tank. The dangerous goods regulations assign them a higher portable tank instruction, most often T14, T20 or T22. Wholesale Industry takes these as sourcing requests, because the tank has to match the product entry exactly.
| Code | Minimum test pressure | Typical build | Typical service |
|---|---|---|---|
| T11 | 6 bar | Bottom outlet allowed | General chemicals and non-hazardous liquids |
| T14 | 6 bar | Top discharge, no bottom outlet | More hazardous liquids, including many corrosives |
| T20 | 10 bar | Thicker shell, top discharge | Toxic and highly corrosive liquids |
| T22 | 10 bar | Thickest shell of the group, top discharge | The most hazardous liquids carried in this tank class |
The table is a guide to why the codes exist, not a selection chart. The instruction that applies is the one printed against your product in the dangerous goods list, together with any special provisions for lining, relief devices or filling. A higher code can generally stand in for a lower one, never the reverse.
Gas tanks such as T50 for liquefied gases and T75 for cryogenic liquids are different vessels altogether and can be requested here too. Say so plainly, and include the product and pressure, so the request is routed correctly. All tank requests start from ISO tank containers.

It is listed against the product in the dangerous goods regulations that govern your route, such as 49 CFR in the United States or the IMDG Code at sea, along with any special provisions. Your safety data sheet or dangerous goods adviser can confirm it. Send the UN number with your request.
Generally yes, because a higher instruction can substitute for a lower one, provided the lining, gaskets and fittings suit the product. Remember that a T14 tank usually has no bottom outlet, so your site must be able to unload from the top.
