According to the International Maritime Organization (IMO) established guidelines, there are certain requirements for the use of FlexiTank to transport hazardous goods by sea. These guidelines include testing and certification requirements for the flexitank and its components, as well as requirements for packing, marking, and labeling of the hazardous material. Shipping lines and container owners’ association, also have their own regulations and requirements for the use of FlexiTank to transport hazardous goods which in most of the cases is not permitting movement of hazardous material by FlexiTank. Ultimately, the use of FlexiTank to transport hazardous goods should be considered as NOT PERMITTED and in some cases can be determined on a case-by-case basis, taking into account type of cargo as well as all relevant regulations and safety considerations.
