They’re air freighting the goods but doing so in bulk, so it ends up being far less than what the customs fees would be. If they were shipping them in bulk to a US warehouse without a designated customer, they’d have to pay customs. But rather, they arrive at a repackager which manages to skirt these regulations - at the expense of the taxpayer and competition who follow the rules.

In other words, they’ve found a loophole to avoid customs on goods with otherwise high tariffs, pocketing some of the money for themselves and using the rest of the savings (and arguably difficult to return lower quality merchandise, we are talking about fast fashion) to undercut competition. I’d think that SV would worship this type of “disruption”.
