Top 5 Customs Issues Set to Challenge Supply Chains in 2026

ArentFox Schiff has released analysis identifying five critical customs and trade compliance issues expected to define 2026, signaling a year of heightened regulatory complexity for supply chain professionals. The outlook reflects mounting trade policy uncertainty stemming from potential tariff escalations, evolving border enforcement protocols, and shifting regulatory frameworks that will directly affect import/export operations, clearance timelines, and compliance costs across North American trade corridors. For supply chain teams, this advisory underscores the need for proactive customs strategy refinement.

Organizations must reassess tariff classification accuracy, supplier documentation protocols, and contingency planning for potential duty rate changes or new origin rules. The five-point framework from ArentFox Schiff likely addresses high-priority areas such as forced labor compliance, de minimis thresholds, Country of Origin Marking (COOM) requirements, broker capacity constraints, and the ongoing impact of trade agreement negotiations. The implications are substantial: delayed clearances, increased duty exposure, and potential supply chain disruptions if companies fail to anticipate regulatory shifts.

Supply chain leaders should engage customs specialists, audit compliance readiness, and establish scenario planning for multiple tariff and regulatory outcomes to mitigate operational and financial risk in the coming year.
