Customs doesn't even know what half the shit is. If I order a quarter-pound of palladium for $4,000 from China, but pay tariffs on 4 ounces of lead (say, $5), do you really think customs can tell the difference? They open the package, see a chunk of metal, and go "okie dokey". Yes, sometimes they'll whip out an XRP gun and double-check the alloy, but not for a completely random & arbitrary 4-ounce package.
This will happen for every. single. product.
They may not inspect the package but they still have to collect duty on it.
I live in Canada where our de minimis exemption is like $20. Generally when a package comes to in it is help at the border where a broker certifies it for customs. Below $20 there's no broker.
Now you need brokers etc for every single package. Def more paperwork even if they keep the same inspection ratio.
Customs used to check everything and tax/duty any parcel over $20 until ~2011 or so.
Not sure if it was because of cutbacks, rationalization (it’s a lot of paperwork to collect a couple bucks even with their, at the time, $6.95 fee), or a part of their reinvention as gun carrying “law enforcement” and consistent tax collection being beneath them.
I'm not saying US customs will inspect everything. My point is on $800 packages they're moving from a very low level of scrutiny to some scrutiny and at scale that matters. They'll need to add staff to handle the new process and make the new process.

It’s at their discretion, just like someone bringing in more than their exemption of beer and deciding not not to charge duty.
