The only motivation for policy makers to do this, is if it would appease swing voters. Voters need to be at least as interested in the human rights angle as the domestic employment angle, if we are to see tarrifs being used specifically as leverage to improve those global human rights.
Otherwise, in spite of gains in redundant manufacturing capacity (great for local employment, and for national security), it's likely there would be a degradation in workers' rights domestically in order to keep costs low. In order to avoid these outcomes, workers' rights and human rights need to be something that most voters believe are important.
