Tank Container Exporter & Product for United States

A UN Portable T11 tank container is the primary standard workhorse for non-hazardous and moderately hazardous industrial chemicals, lubricants, and solvents. It operates with bottom-discharge valves and a test pressure of 4.0 bar (typical working pressure 2.65 bar). In contrast, a T14 tank container is mandated for highly toxic, corrosive, or hazard-critical liquids (such as specific inhalation-hazard chemicals, sulfuric acid, or chlorosilanes). T14 vessels require a 6.0 bar test pressure, top-discharge only configurations with no bottom shell penetrations below liquid level, and enhanced shell wall thickness per 49 CFR and IMDG code specifications.

Yes. All tank containers destined for North American deployment are engineered and dynamically tested in strict compliance with the Association of American Railroads (AAR) Standard AAR-600. This includes structural testing against longitudinal rail impact loads exceeding 4G to 6G deceleration, ensuring the end-frames, tank saddles, and corner castings withstand the unique shunting and coupling stresses of US freight rail systems (BNSF, Union Pacific, CSX, Norfolk Southern).

The US Federal Bridge Gross Weight Formula restricts standard 5-axle tractor-trailer combinations to a maximum gross vehicle weight of 80,000 lbs (approximately 36,287 kg). Because an empty chassis and day-cab tractor weigh roughly 26,000 to 30,000 lbs, the usable payload for the container and liquid contents is typically limited to 44,000 to 48,000 lbs (20,000 to 21,700 kg). When carrying dense chemicals (specific gravity > 1.2), shippers select smaller volume tanks (e.g., 17,500 L to 21,000 L) to avoid violating highway axle weight limits, whereas lighter products use 24,000 L to 26,000 L capacities.

Absolutely. Our dedicated food-grade liquid containers comply with US FDA regulations (Title 21 CFR) and international sanitary protocols. These vessels are manufactured from medical/food grade 316L stainless steel, feature mechanical internal polishing up to 320 grit (Ra ≤ 0.4 μm) or electropolishing, dedicated CIP (clean-in-place) dual rotary spray balls, sanitary butterfly or diaphragm valves, and tamper-evident locking mechanisms preferred for juices, wine, high-proof spirits, and edible oils.

Standard OEM/ODM production runs typically require 4 to 8 weeks depending on vessel customization, specialized internal lining requirements, and third-party inspection schedules. Our manufacturing centers are situated approximately 100 km from Tianjin port, allowing rapid coastal transit. Maritime transit times to US West Coast ports (Los Angeles, Long Beach, Seattle) range from 16 to 22 days, while transit to US Gulf and East Coast gateways (Houston, Savannah, Norfolk, NY/NJ) spans 28 to 35 days via direct ocean container liner services.
