A federal trade court ruled this week that President Trump's sweeping 10% baseline tariffs are not authorized under U.S. trade law, opening the door to a cascade of legal challenges against the broader tariff architecture — and immediate uncertainty for every importer currently pricing goods under those rates (New York Times, Yahoo Finance/CBS News). The ruling does not instantly zero out duties, but it signals that a significant share of the tariff stack in place since early 2025 may be legally vulnerable. At the same time, Trump threatened the EU with tariffs of "much higher" than current levels if no trade deal is signed by a new July 4 deadline, even as EU negotiators failed to reach agreement among themselves this week (BBC, Politico EU). Compliance teams face a rare double-pressure scenario: existing duty liabilities may be contested in court while new exposures are being announced simultaneously.

What Changed This Period

United States. The court ruling against the 10% blanket tariffs is the headline legal event; the New York Times and CBS News both reported it as a direct challenge to the administration's primary tariff mechanism, with future court challenges to Section 232 actions now considered more viable as well. Separately, Trump stated that auto and truck tariffs on EU-origin goods will rise to 25%, tied to the July 4 trade deal deadline (BBC, finance.yahoo.com). On the Federal Register front, Commerce published final antidumping results for cut-to-length carbon-quality steel plate products from South Korea (FR 2026-09131) and final results plus partial rescission for thermal paper from South Korea (FR 2026-09132), both effective this period. Commerce also published preliminary countervailing duty results for wood mouldings and millwork products from China (FR 2026-09218), and preliminary antidumping results for strontium chromate from France showing zero dumping margins for the 2023–2024 period (FR 2026-09220). ATF proposed a rule that would amend the definition of "importation" for firearms activities in Foreign Trade Zones and customs-bonded warehouses — relevant to any importer using FTZ programs for firearm-related goods (FR 2026-09162). The ITC declined to institute a changed-circumstances review for coated paper from Indonesia (FR 2026-09240).

Canada. No tariff schedule changes were recorded in the TradeFacts.io Canadian Customs Tariff feed since the last issue. Separately, the Canadian government announced C$1.5 billion ($1.1 billion) in aid for firms hurt by U.S. steel tariff changes, and a Canada–U.S. trade deal reported to include tariff-rate quotas on steel collapsed before finalization (Bloomberg, Politico).

Mexico. No changes to the TIGIE schedule were recorded since the last issue.

One Practical Action

If your entry summaries include duty paid under the 10% blanket tariff — particularly on goods not covered by a separate Section 232 or Section 301 order — flag those entries for potential protest now. The court ruling cited by the New York Times and Yahoo Finance suggests the statutory basis for those charges may not hold. Pull your CBP entry records for the past 180 days, identify lines where the 10% rate was the operative column, and consult your customs counsel on protest deadlines (generally 180 days from liquidation). Acting before liquidation closes your window is the most time-sensitive compliance step this week.
