Take another look at the box pictured in the CBP press release:
Securing America's Borders

There is no Apple branding on it at all. There is however bold (and red) OnePlus branding.
Compare this to the Apple (white) packaging:
Apple AirPods are more than just great wireless earbuds that are thoughtfully designed. Including the way they are packaged.

Now have a look at the actual product:

I would say that nobody that is even remotely experienced with actual AirPods (and cares at all) would mistake these for an Apple product.
I think this answers your question.
