TDI reacts with moisture and water. It comes under cyanide group of cargoes and is highly toxic. It can ingest through the skin. And not the physical contact but even its vapors can ingest through the skin. And after all these, TDI may require heating as its melting point is high. So many dangerous elements in one cargo and that's why it is important to handle it carefully. Handling TDI cargo But in spite of being so dangerous, there are hardly any cargo-specific guidelines for carrying this cargo on ships.

    Thanks for the write-up. It`s really a good read and also looks promising market. I went through a toluene diisocyanate market report at valuemarketresearch.com that evaluated the market across various segments. A deep dive into it might be profitable.
