US-China Trade: November 10, 2026 Deadline Approaching — New USTR Forced-Labor Tariff Adds Complexity

The US-China trade architecture as of August 13 is a layered structure that requires careful mapping by trade counsel: the Kuala Lumpur Arrangement (November 2025) suspended the heightened IEEPA reciprocal tariffs through November 10, 2026; a 20% fentanyl-related tariff remains in effect; country-specific reciprocal tariffs under the post-Supreme Court Section 122/301 framework are in effect; and USTR imposed a new 12.5% forced-labor tariff on all Chinese goods effective July 24, 2026, citing China's "failure to impose and effectively enforce a prohibition on the importation of goods produced with forced labor." The forced-labor tariff is legally grounded in Section 301 — a route that survived the Supreme Court's February 2026 IEEPA ruling — and creates a new layer of import duty that applies on top of the existing tariff stack. For clients with supply chains involving Chinese-origin goods, the tariff stack now includes the baseline, the fentanyl tariff, the post-IEEPA reciprocal tariff, and the forced-labor tariff, with the November 10 deadline presenting the risk of the reciprocal tariff layer snapping back if no further arrangement is reached. The legal planning implication is a November scenario analysis: what does the tariff stack look like on November 11 if negotiations fail, and what supply chain, sourcing, and contract adjustments need to be in place by then?
