If Donald Trump wins next month's U.S. presidential election, Mike Sagan's toy-making company will halve its China supply chain within a year.

KidKraft, which also makes outdoor play equipment, had already shifted 20% of its production out of China to Vietnam, India and elsewhere after Trump introduced 7.5%-25% tariffs in July 2018, midway through his first term.

Now Trump threatens blanket 60% tariffs on China, which Sagan sees as a game-changing "blunt" tool.
