| 1 | Common frame size | Many tank containers use a nominal 20-foot ISO frame. | Check the unit’s approved drawings and applicable ISO dimensions. |
| 2 | Typical 20-foot frame dimensions | A common 1CC container envelope is approximately 6.058 m × 2.438 m × 2.591 m (L × W × H). | Dimensions refer to the frame envelope; verify the specific unit and configuration. |
| 3 | Tank capacity | Capacity is design-dependent; many standard liquid tank containers are in the approximate 17,500–26,000 L range. | Confirm rated capacity, payload, and filling limits for the intended cargo. |
| 4 | Tank shell material | Stainless steel is widely used; grades such as 304/304L or 316/316L may be selected according to cargo compatibility. | Material choice should be checked against chemical compatibility and cleaning requirements. |
| 5 | Design and test pressure | There is no single pressure rating for all tank containers; requirements depend on the tank design and service classification. | Compare the nameplate and design documents with the required cargo and transport rules. |
| 6 | Insulation and heating | Insulation and heating systems are available on some designs but are not universal features. | Specify the required temperature range and heating method for the cargo. |
| 7 | Tank-container design standard | ISO 1496-3 covers specifications and testing for series 1 tank containers. | Confirm which edition and requirements apply to the unit being supplied. |
| 8 | Container safety approval | The International Convention for Safe Containers (CSC) establishes safety requirements for covered containers used in international transport. | Check the safety approval plate and examination status. |
| 9 | Dangerous-goods compliance | Applicable rules depend on the cargo and route; international sea transport may be subject to the IMDG Code. | Confirm the required tank instruction, approvals, markings, and route-specific regulations. |
| 10 | Valves and fittings | Manlids, discharge valves, vents, and other fittings vary with the tank design and cargo service. | Review fitting materials, connection types, and operating procedures before procurement. |
