Yes, that was my point. If you only tariff raw copper (which is what the parent thought), you could avoid the tariff by importing lightly process copper (e.g. a spool of 0000 wire instead of bar of copper).
Yet another tarrif level is often set on "semi-finished goods" too.
It does seem like these tariffs haven't really been thought through though, so I wouldn't be surprised if "hacks" existed.
