# Tariff Trends 2026: Expert Insights on the Evolving U.S. Tariff Landscape

This webinar covers the U.S. tariff landscape as of September 16, 2026, with a focus on the escalating U.S.-Canada trade dispute.

Topics include the first-ever use of Section 338 to impose 50% duties on Canadian-origin goods, the September 15 product additions and removals, and import bans starting September 29 on motorcycles over 800cc, whey products, molasses, nonalcoholic beer, and small-format alcoholic beverages. It also covers stacking rules, drawback and Chapter 98 eligibility, Canada's dollar-for-dollar retaliation, and where negotiations stand.

Jenn Park walks through stronger CBP enforcement: the September 18 IOR validation deadline on CBP Form 5106, new CTPAT requirements for foreign importers of record, the trade fraud task force memo, a 148% jump in CF 29s, and transshipment fraud.

Calum Coulter closes with a CAPE update: $135 billion in refunds accepted, $122 billion transmitted, ACH rejection issues to check in your ACE account, and CAPE phase three launching October 6 for CIT plaintiffs with importer-specific orders of relief.
