I don't mind paying an extra 10% on small electronics imports (mostly ESP32 CPUs and related modules for hobby projects). I mean, I do a bit but I rarely order more than $100 of goods at a time, it's just an annoyance rather than a real problem.
The language of the order getting rid of the exemption seems to reclassify all Chinese post as formal post to get around the exemption.
That means the amount of dues is still calculated as a (fraction of a) percentage, but there is a minimum of about 30 dollars. That means a $10 order of components or LEDs can end up costing you $42 to actually get it through the mail.
When you go beyond those thirty dollars, the rate isn't too steep, though, so you can still order in large quantities.
I DO mind not getting my orders delivered.
