01 · The brief

The bill amends the Tariff Act of 1930 to require manifests for vessels, vehicles, and aircraft arriving in the United States to include specified cargo details and to make certain manifest information publicly available.

It adds each HTSUS subheading for cargo classification, expands required country-of-origin and last-transit reporting, broadens the term “aircraft” to include civil, military, and public contrivances, and makes the changes effective 30 days after enactment.

Passage20/100

Contentious disclosure/security tradeoffs, industry pushback, and lack of compromise features lower prospects despite limited fiscal impact.

CredibilityMisaligned

Relative to its intended legislative type, this bill makes direct, specific statutory changes to require public disclosure of enumerated manifest fields and to extend manifest requirements to vehicles and aircraft, but it provides minimal implementation detail, no funding or resource provisions, and no safeguards or accountability mechanisms.
