US President 
Donald Trump imposed new tariffs of 10% to 12.5% on imports from 60 countries — accounting for 99% of US imports — under Section 301 of the Trade Act citing forced-labor concerns. Per France 24, Trump imposed the duties Thursday replacing temporary levies that expire Friday after the Supreme Court struck down his earlier trade measures. Per Al Jazeera, the new tariffs come as existing 10% levies expire. Per the Guardian, more than 80 trading partners are affected. Per NPR, the US charges the countries with inadequately enforced bans on goods produced by forced labor. Per Japan Times, Trump rebuilds tariffs with forced-labor duties on 60 economies.
What's the scale? 10% to 12.5% tariffs on 60 countries accounting for 99% of US imports. The sweeping-scope operationalises substantive-global-trade-architecture impact.
What's the Supreme Court context? The Court struck down Trump's earlier trade measures. Section 301 forced-labor duties operate under alternative statutory authority.
What's Section 301? A US Trade Act provision allowing tariffs against countries that engage in unfair trade practices. The forced-labor-provision architecture extends substantive Section-301-flexibility beyond traditional-market-access disputes.
Which countries are affected? Deep-scope coverage. Japan Times: EU and Taiwan at 10% minimum, Japan at 12.5% minimum. Yonhap: South Korea at 12.5%. Guardian: Australia affected.
What's the Australia dimension? Australian trade minister Don Farrell framed the tariff regime as "unjustified and inconsistent with free trade agreement with US", per the Guardian. Substantive-treaty-compliance concern from a substantive-ally partner.
What's the "99% of US imports" framing? The 60-country coverage reaches 99% of US imports by value. Near-universal-scope operationalises substantive-general-tariff architecture rather than targeted-partner dispute.
Why "forced labor"? The framing operationalises substantive-human-rights-plus-trade-policy fusion. Substantive-enforcement-track for forced-labor bans has been variable across trading-partner architectures.
When does the 10% global duty expire? Friday. The forced-labor tariff replaces the expiring duty — maintaining substantive tariff-continuation architecture across the transition window.
What's the Korea response? Yonhap flagged the 12.5% South Korea tariff.
How does this compare to the Canada tariffs? Monday's 50% Canada tariffs operate on a substantially different scale than the 10-12.5% forced-labor category.
What's next? Country-by-country negotiation-track proceedings and substantive-legal challenges to Section-301 forced-labor framework will define the coming weeks.
