Standard Tank Container fitted with Baffles
T11 & T14 Tank Containers: Safe Transport for Chemicals, Food, and Classified Products
Standard tank containers with baffles ensure the safe and compliant transport of liquids. This is especially true for chemicals, food-grade products, and classified substances. Manufacturers design these containers to meet the T11 specification for non-classified products. However, transporting more demanding classified products, such as acids, requires the higher T14 specification. Upgrading standard tank containers with baffles to the T14 specification meets safety regulations. It also improves the ability to handle hazardous materials.
Tank Containers Built to International Standards
Standard tank containers with baffles meet a range of international standards. These include ISO, CSC, TIR, UIC, and UN Portable Tank rules. For example, US-DOT, IMDG, and ADR 6.7 regulations are also followed. Many standard tank containers with baffles hold dual certifications, such as ADR Tank 6.8. This flexibility allows these containers to adapt to various transport methods and product types. As a result, they meet the diverse needs of global logistics.
Baffled Tanks for Classified Products
When weight regulations prevent achieving the minimum loading degree of 80%, operators can add baffles to standard tank containers with baffles. For example, a 15,000-liter standard tank container with baffles typically includes one baffle. A 22,500-liter standard tank container with baffles uses two, and a 26,000-liter standard tank container with baffles typically has three. Adding these baffles improves safety during transport. It also ensures compliance with IMDG or ADR regulations. Additionally, it helps operators manage weight and cleaning hatch requirements more effectively.
Regulations for Safe Transport
To ensure safe transport, operators must fill standard tank containers with baffles to at least 80% of their capacity. If the tank does not have sections smaller than 7,500 liters, the fill must be reduced to no more than 20%. This practice helps maintain stability during the transport of liquids. For more details, refer to the IMDG or ADR regulations (sections 4.3.2.2 / 4.3.2.4). You can also contact our expert team for assistance with standard tank containers with baffles.

Details of Standard Tank Containers fitted with Baffles
An operator fits a 20”/DN500 manlid with 8 swing bolts. The operator also fits the manlid with a standard PTFE braided gasket, but they can optionally change it to other gasket materials
To achieve good cleaning performance at automated cleaning facilities, operators add 3 or 4 extra cleaning openings: a 12”/DN300 manlid, fitted with 4 swing bolts. The operators fit the cleaning hatch with a standard PTFE braided gasket, but they can optionally change it to other gasket materials.
Manufacturers fit the interior of the vessel with vertical corrugated stainless steel baffles (316L). These baffles cover 70% of the internal diameter, and their vertical shape makes it easy for operators to access and walk inside the tank.
The manufacturer fits the Unportable tank T11 with a 3-closure bottom discharge, supplied by a worldwide leading manufacturer. The discharge valve includes a high-lift internal valve that operators can close remotely via a cable on the side of the tank container, a butterfly valve as the second closure, and a 3” BSP spigot as the third closure.
Regularly we modify the connections on customer request to a cleanflow version or changing the BSP connection to a quick release coupling. Our team is here to assist.
Most tank containers are built for future fitment of a bottom cabinet (floor and door) for a clean operation and easier fitment of TIR seals.
The manufacturer fits a standard tank with a DN80/3” connection on top. On request, operators can add a connection for easy filling and discharge from the top, and our team can assist with installing a bottom-operated top discharge as one of the options.
To release air during loading and discharge, the manufacturer fits a ball valve on the top. The standard size is 1.5”/DN40 with a BSP connection. On request, operators can change this connection to a flanged version, a 2” valve, or a bottom-operated version.
For full bottom operation, operators can extend the airline to the bottom (GOVR), including a bottom-operated airline valve, piping to the bottom/rear of the tank, and a manometer with a second valve (dimensions and connections to be discussed).
The manufacturer fits a T11 tank container with a safety valve that opens at 4.4 bar (10% above the test pressure). In addition to the pressure-only version, operators can choose the pressure + vacuum version as an option. Each tank container is also prepared for the future installation of a bursting disc (needed for both T12 and T14 specifications).
The manufacturer makes the frame from mild steel to meet the ISO dimensions of a 20ft box container. The barrel connects to the frame and is part of the integral construction; therefore, operators do not need top rails but can add them upon request.
The manufacturer fits each tank container with a stick-on analogue thermometer, reading from -20°C to a maximum of 160°C. On request, operators can add a digital version or thermometers with a probe for more accurate product temperature readings.
The manufacturer fits each tank container with an anti-slip ladder at the rear side to provide easy access to the top of the container.
The manufacturer fits each container with an aluminum walkway to access the manlid, safety relief valve, and airline. The minimum layout includes one longitudinal walkway and transverse sections between the spill boxes. On request, operators can add additional walkways as well as spill box covers for a cleaner operation and easier fitment of TIR seals.
On request, operators can also fit one or two collapsible handrails, both top and bottom operated.
The manufacturer fits each tank container with a minimum of 8 steam runs to heat the product with warm water or steam. The covered area is 8 SQM. On request, operators can upgrade the number of steam runs to 12. Additionally, operators can add a water glycol/electrical heated system.
A small part of the fleet is non-insulated, while the majority has 50mm insulation and cladding. The insulation material varies, including PU, Rockwool, glass wool, or a combination. The cladding material is either aluminum, GRP, or stainless steel.
