Sorry, I didn't mention it earlier, since you seemed upset by Customs in general. This certainly appears to be a false positive, and it will most likely get resolved in favor of the importer, unless there's some trademark action we're all unaware of. The shipment is still gonna be delayed though, and that delay is not likely to be compensated; it's a risk in the system (along with many other risks of loss or delay in international shipping)
It would probably be better for CBP not to publish their seizures like this until they had gone through the process.
I'm not particularly upset by Customs in general, but I get upset when they stretch or abuse their already far reaching authority and privileges. Mainly because I strongly believe that all extreme powers come with extreme responsibility and require extreme accountability in order to not end up being used for all the wrong reasons.
This action, including its publication, smells like brutally political, shortsighted, and very likely unlawful (though Customs lives mostly by definition outside the usual legal territory, so there goes accountability).
Part of me stopped caring about it a long time ago, when it became clear that the USA is hellbent on accelerating its inevitable demise (as a defacto empire), as long as it can make powerful companies and politicians a few quick bucks along the ride.
On the other hand, it still hurts to see stupid things like these happen, while most people appear clueless about the consequences. I know it will be ordinary American citizens that ultimately will pay a price for this, with time.
That still pisses me off .. and hopefully it will always remain doing so.
