The Office of the United States Trade Representative has proposed new Section 301 tariffs covering 60 trading partners, according to a JD Supra report. The proposal signals a wider use of the statute beyond its original China-focused investigations and opens a new cost-side variable for brands mapping 2026 sourcing budgets.

What Section 301 covers in practice

Section 301 of the Trade Act of 1974 empowers USTR to impose duties on imports when it finds a trading partner maintains unfair or discriminatory practices that burden U.S. commerce. The mechanism allows tariff rates above the standard Most Favored Nation column and was the legal basis for the 2018–2019 China tariff rounds, which raised duties on broad swathes of textile and apparel HTS lines. A new action against 60 economies suggests USTR is broadening its target list rather than concentrating on a single jurisdiction.

For sourcing teams, the first question is product scope. Section 301 actions have historically distinguished between consumer goods, intermediate inputs, and capital equipment, and the proposed list may carry similar carve-outs. Garment, footwear, and accessory buyers with diversified country-of-origin matrices are likely to face the most immediate re-pricing exercise once tariff schedules are published.

Why the country count matters for sourcing

A 60-economy proposal changes the calculus for buyers who moved production out of China during the 2018–2020 tariff window. Vietnam, Bangladesh, India, Indonesia, Cambodia, and Mexico all absorbed significant cut-and-sew and finished-goods volume in that period. If any of those origins feature on the new list, the diversification strategy that many brands and retailers documented as their post-China playbook would partially unwind. Compliance teams will need to revisit preferential-trade and FTA claims, since Section 301 duties typically stack on top of normal customs treatment and can override otherwise-applicable preference programs.

Lead-time planning also shifts. Apparel and footwear programs already run on 90–180 day calendars with confirmed fabric commitments. New tariff exposure shortens the window for origin changes that do not disrupt inventory, and it raises the cost of carrying dual sourcing across regions pending clarification of which HS codes the proposal targets.

What the proposal does not yet say

The JD Supra notice references the proposal but the available text does not enumerate the 60 jurisdictions, the proposed ad valorem rates, the effective date, or the exclusion process. Sourcing professionals should treat the announcement as a signal to begin scenario modeling rather than as an actionable tariff schedule. USTR typically opens a Federal Register notice with a public comment window and a hearing schedule before any duties take effect, and the eventual list often differs materially from the initial proposal.

The notice also does not state whether the action responds to specific unfair-practice findings (such as forced-labor concerns, digital-service taxation, or intellectual property enforcement) across the named economies. The legal predicate matters because it determines whether products can be exempted through compliance programs and whether retaliation from trading partners is likely.

Practical next steps for buyers

• Pull the most recent 12-month customs entry file and rank suppliers by country of origin and HTS chapter to identify exposure if major apparel and footwear origins appear on the final list.
• Re-price at-risk programs using a range of Section 301 rate scenarios and compare the margin impact against the cost of an origin shift.
• Confirm whether current vendor contracts pass through tariff cost or absorb it, since the answer reshapes negotiations on new PO terms.
• Track the Federal Register notice and USTR hearing calendar; exclusion requests historically require supplier-side documentation filed within a defined window.

Brands and sourcing teams should expect the proposal to harden into a formal investigation list within weeks. The next data point to watch is the published economy roster and the accompanying product coverage, because those two variables determine whether the 60-economy action becomes a margin event or a sourcing-architecture reset.
