you can fly a few hundred million dollars worth of chips in a single flight. You need not be concerned. The impact from temu shipments is several orders of magnitude higher.

e.g. you can get 572 a15 dies per 300mm wafer at 90% yield. These likely weigh a few hundred grams.

By my rough calculations a million iPhones of a15s is about 200kg of silicon. excluding packaging, which would dwarf this mass entirely.
