Frequently asked
How do stacked US tariffs affect my import costs?
A product from China may face base duty (e.g., 3.4%) plus Section 301 tariff (25%) plus Section 232 steel/aluminum surcharge (25%), totaling 53.4% before MPF and HMF fees. On a $50,000 shipment, that is $26,700 in duties alone. This calculator layers all applicable tariffs to show your true landed cost.
Can I reduce tariff liability through classification changes?
Yes. Reclassifying under a different HS heading can reduce duty by 5-20 percentage points (e.g., "parts" vs. "finished goods"). Country-of-origin shifts via substantial transformation in a third country may eliminate Section 301 tariffs entirely. This tool shows the cost difference across alternative classifications before you consult a customs broker.
