Customs Enforcement Trends to Watch in 2026

Young CompanyFTZ News

Customs enforcement is shaping how imports enter the United States in 2026, and businesses that stay informed are better positioned to manage risk. After several years of elevated tariffs and regulatory pressure, U.S. Customs and Border Protection is maintaining a firm enforcement posture focused on revenue protection and data accuracy.

For importers, customs directly affect cost, timing, and operational stability across the supply chain.

What Customs Enforcement Trends Should Importers Watch in 2026

Customs priorities in 2026 build on patterns established in 2024 and 2025, with continued scrutiny in high-risk areas.

Tariff-sensitive imports remain a priority

Imports subject to Section 301 and Section 232 measures continue to receive enhanced review. CBP enforcement summaries show that misclassification tied to tariff exposure remains one of the most frequent audit findings, particularly for steel, aluminum, electronics, and automotive components

Valuation and origin reviews are expanding

CBP is increasing focus on related party valuation and country of origin claims. Several enforcement cases over the past two years involved undervaluation schemes and unsupported origin declarations, resulting in significant penalty assessments.

Data-driven targeting is accelerating

CBP continues to expand its use of data analytics within the Automated Commercial Environment. Entry patterns, inconsistencies across filings, and supplier trends are increasingly used to trigger document requests and post-entry reviews, especially for high-volume importers.

Foreign Trade Zone oversight remains strong

Imports moving through Foreign Trade Zones continue to face focused compliance reviews. The FTZ Annual Report for 2024 highlighted increased CBP attention on inventory controls, admission accuracy, and reconciliation practices as zones play a larger role in tariff management.

Recent Enforcement Examples

In 2025, CBP announced multiple enforcement actions related to steel imports that were improperly classified to avoid duties. Other cases involved consumer electronics importers penalized for undervaluation tied to tariff exposure. These actions reinforce CBP’s emphasis on accuracy where tariffs are involved.

How Importers Can Prepare

As importers enter 2026 they should take these proactive steps:

  • Review tariff exposure by product and supplier
  • Validate HTS classification and origin documentation
  • Strengthen valuation support and recordkeeping
  • Align customs, sourcing, and logistics teams

Enforcement expectations are steady, not temporary. Preparation remains the most effective defense.
