Bizarre, tax/tariff evasion or "Mistake" does seem like the most likely explanation - yet US$1.4m is too little to bother evading tax on really. I mean that could be a refit on a boat or something -- $1.4Mn is literally nothing.
In the case of Norfolk Island, it was apparently some mislabeled shipments from Timberland (based in New Hampshire, NH <-> NI) and from two companies based in Norfolk, UK.
For Heard & McDonald Islands, it was mislabeled machinery that actually originated in Austria and Germany.
Now it is 1.4 mln, in future this could be 1000 more, if this will help with overcoming tariffs. Check what happened with Germany export to Kazakhstan in 2022.

Can you elaborate? Tried searching for it, all i found is that Kazakhstan reported 500M exports to Germany, when it was actually 7B. But you were talking about Exports from Germany to Kazakhstan, which I wasn't able to find.
Of course, several of these islands with 10% tarrifs are ex-colonies of various EU countries. Of course any french manufacturer will send goods to the islands (0%) then from there to the US (10%) rather than pay 20%. It's obvious, then the US will notice and the island will go to 20% and so on. It's all completely hateful.
