IMDG Compliant. Carrier Refused. Twenty Years of IMO Guidance on Class 7 Radioactive Cargo and Why It Has Not Worked In December 2018 I wrote about carriers and ports refusing IMDG-compliant Class 7 radioactive cargo despite advisory guidance from the IMO.

Radioactive Cargo by Sea: When IMDG Compliance Is Not Enough When a charterer offers radioactive cargo, IMDG compliance is only half the question. The half that determines whether your P&I covers you is governed by the UK Nuclear Installations Act 1965 — not the IMDG Code. This article explains the Excepted Matter test, what the four major clubs require, and what happens when a cargo declared "fissile excepted" turns out not to be Excepted Matter at all.... https://shashikallada.com/2026/08/03/radioactive-cargo-sea-pi-cover-excepted-matter/
