On September 2, 2026, U.S. Customs and Border Protection (CBP) issued an advance notice of proposed rulemaking (Notice), titled Heightened Import Disclosures for Supply Chain Visibility (Docket No. USCBP-2026-1058; RIN 1685-AA47).

The Notice, issued as part of Executive Order 14411, “Strengthening Customs Enforcement,” aims to enhance transparency across supply chains and strengthen efforts to detect and prevent illicit imports, including illegal transshipment. To achieve this, CBP is exploring significant changes to import filing and record keeping processes.
