Are dividends from Syfe's portfolios subjected to US withholding tax?

Syfe Core and Syfe Select portfolios are ETF portfolios. For US-listed ETFs, such as the equity-based ones, there is a 30% withholding tax on dividends. This would be applicable even for Hong Kong-based investors who buy these ETFs on their own.

Some of the ETFs, such as the gold ETF, do not pay dividends and so do not incur any withholding tax.
