Shares in Link will not be subject to witholding tax wherever you hold them, and FWIW I think HSBC expat only allows for US and UK sharedealing anyway. Likewise stocks or ETFs that are UK based like Shell or a FTSE 100 tracker will be paid without any witholding tax wherever you hold them.
US stocks and ETFs listed in the US like VOO and QQQ, or in HK like 3140, are subject to 30% witholding tax wherever you hold them.
