Apple... it's said that around 80% of Apple products, most phones, most laptops etc are manufactured in China. It's not just Apple... an estimated 7 out of 10 American-owned smartphones (Androids as well as Apple) are Made In China.
WalMart .... estimates are that 70% of all their inventory comes from (or has been coming from) China.
L.L. Bean.... believe it or not, despite their Maine folksy branding and origin story, around 65% to 75% of LL Bean's entire catalog is Made In China.
Amazon.... approximately 70% of everything sold on Amazon is sourced from China.
What others? I believe many shoe/footwear companies are similar, even some rather upscale brands.
