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.
So if Foxconn is assembling a phone from components, they are paid for just that. The export is labor, not a fully valued finished phone.
