Most of that $600 is BOM inputs where most of high end components worth $$$$$ is ultimately captured by US / western suppliers (i.e. chips, sensors, screens for iphones). The actual value of export from PRC in terms of material and labour is $, but still counted as $$$$$+$. Though iphone/high tech unique since US plays hand - sanction $$$$$ PRC components so Apple can't integrate them and raise PRC share of Apple BOM, which IIRC grew to ~20% and on way 40%+ (prc memory + screen) and now <20%. This is something PRC stats has started adjusting for.
No, I should have been more clear relative to original comment. I was pointing out even % Apple charge customs, i.e. imports from PRC, large % is still ultimately not value captured by PRC.
For full priced iphone, i.e. $1200, Apple captures or offshores another big slice of $800 in Ireland for intangibles like software related IP. But within the $400-600 BOM for physical device / import unit cost for customs, ~80% are western components, i.e. western value capture.
