How do Tariff Commission decisions interact with Customs authorities?

• A. Tariff Commission findings inform Customs duty assessments, enforcement, and may require adjustments in tariff schedules; Customs enforces the measures directed by the Commission's rulings.
• B. Customs enforces the measures directed by the Tariff Commission's rulings.
• C. Tariff Commission writes separate laws for Customs.
• D. Customs determines remedies without Commission input.

Answer: (A)

Tariff Commission decisions provide the framework that Customs must apply in practice. The Commission studies tariffs, trade remedies, and tariff classifications and issues rulings or recommendations. Customs then implements these decisions in the clearance process: applying the specified duty rates, enforcing the measures, and adjusting tariff schedules or classifications as directed. This linkage ensures that the Commission’s findings actually affect duty assessments and how imports are regulated. For example, if the Commission recommends a higher duty or the imposition of an anti-dumping measure, Customs enforces that duty at entry and collects the revenue, or applies the added restrictions. The other options miss this coordinated flow—the Commission guides the measures, and Customs enforces and adjusts administration accordingly; they do not write separate laws for Customs, nor operate independently without Commission input.
