The only people who don't recognize a muscular customs enforcement regime is imminent are those not paying attention.
The de minimus loophole, which is the only reason the floodgates to Chinese gear opened wide, will cease to exist in its current form.
The Chinese suppliers know this. It's their primary motivation for opening US warehouses. The direct shipping from China model will be coming an end, because just like it wasn't practical 20 years ago due to the high likelihood of getting seized, it's going to return to that. Plenty of European countries are already "No reship" "High risk" locations because they're not dealing with the surge of small packs from China de minimus enabled in the US, overwhelming custom's ability to screen them.
It's the shipping equivalent of 100 people mobbing a retail store and all rushing through the doors with stolen goods. The crackdown has been slow in coming, but the pieces are all in place, and with the election behind us it's going to be full speed ahead.
And to preempt the clown car that'll be pulling up, I said the end of "Cheap and Easy", not "unavailable at any price".
