On June 11 the Court of Appeals for the Federal Circuit stayed a lower court ruling that had found the 10% worldwide baseline tariff unlawful, letting the Trump administration keep collecting it while its appeal proceeds (June 11; AP News, Washington Post, The Hill). That 10% layer is the Section 122 tariff (Proclamation 11012) Trump imposed in February as a replacement after the Supreme Court struck down the earlier IEEPA tariffs — a distinct measure from the IEEPA refunds noted below.

For compliance teams, the practical read is clear: do not adjust landed-cost models or stop applying the 10% layer — it remains operative on all covered entries until the court issues a final ruling. Separately, seven new Chapter 99 HTS codes covering derivative steel and copper/aluminum articles landed in the US schedule on June 9, signaling continued regulatory build-out around the Section 232 metals framework.

What Changed This Period

United States. The Federal Circuit's June 11 stay means the 10% Section 122 baseline tariff stays in force for now (AP News, Washington Post, The Hill). The underlying Court of International Trade ruling (May 7) had granted relief only to its three named plaintiffs — two small businesses and the State of Washington — so collection from the broad importer base was never actually halted; the practical read is that nothing changes at the entry line for now.

On the HTS schedule side, the June 9 batch (records 35607 → 35614: seven added, four modified) added seven new Chapter 99 codes: 9903.82.20, 9903.82.21, 9903.82.22, 9903.82.23, 9903.82.24, 9903.82.25, and 9903.82.26. Codes .20–.22 cover derivative steel articles; .23–.26 cover articles of copper and derivative aluminum and steel articles at varying ad valorem thresholds. Provision 9903.82.22 carries country-specific carve-outs for Argentina, Ecuador, El Salvador, Guatemala, Japan, the Republic of Korea, Liechtenstein, Switzerland, Taiwan, the United Kingdom, and EU member states. Importers of downstream steel and copper-containing manufactured goods should audit whether their products now classify under one of these new provisions in addition to their base chapter codes.

On the AD/CVD front, notable Federal Register activity this period:

Also new this period: a Presidential Document on Strengthening Customs Enforcement (FR 2026-11595, June 10) — worth reviewing for operational mandates affecting any importer with high-volume informal entries.

On the macro side, the Treasury refunded nearly $22 billion in tariff revenue in May (Bloomberg, June 10) — the first swath of repayments of the IEEPA duties the Supreme Court struck down, roughly equal to the tariffs collected that month. These are court-ordered IEEPA refunds, not routine exclusion or drawback activity. Separately, EU exports to the US fell by roughly one-third year-on-year in Q1 2026 (Eurostat, via Euronews), a leading indicator that EU-origin supply chains are repricing and reshoring sourcing decisions.

Canada. No changes to the Canadian Customs Tariff schedule since the last issue.

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

One Practical Action

Pull every open entry line where the base chapter covers a downstream steel- or copper-containing article and check it against the seven new codes — 9903.82.20 through 9903.82.26 — added in the June 9 US HTS batch. The country-specific carve-outs under 9903.82.22 (Argentina, Ecuador, El Salvador, Guatemala, Japan, Korea, Liechtenstein, Switzerland, Taiwan, the UK, and EU member states) are easy to miss if your classification workflow only flags the umbrella derivative-steel provision. Run the TradeFacts.io API against your product catalog using Chapter 99 filtering to surface any items that may now require a secondary HTS annotation before your next entry summary is filed.
