Why Tariff Calculators Are Suddenly Everywhere in 2026
Two major changes have made import duty a live concern for far more people than just professional importers. First, the $800 "de minimis" exemption — which used to let low-value parcels and e-commerce orders enter the US duty-free — has been suspended, so shipments that once cleared customs with no duty at all can now owe tariffs regardless of their value. Second, the U.S. Supreme Court struck down the 2025 "reciprocal tariff" regime that had been imposed under emergency economic powers; a new baseline tariff has since been applied under different legal authority, while separate sector-specific tariffs on steel, aluminum, automobiles, and auto parts remain in force.
How This Calculator Works
Landed Cost = Customs Value + Freight & Insurance + Duty Owed
Enter the declared customs value of your shipment (typically the price paid for the goods), any freight and insurance cost you want included in your landed-cost estimate, your expected baseline duty rate, and any additional sector-specific surcharge that applies to your product category. The calculator instantly shows your estimated duty and total landed cost.
Why We Don't Hardcode a Rate by Country
Actual tariff rates in 2026 vary enormously by product classification (HTS code), country of origin, applicable trade agreements (like USMCA), and ongoing trade actions and litigation that are still being resolved in court. A single lookup table risks showing you an outdated or simply wrong number for your specific shipment. Instead, this tool defaults to the widely-reported ~10% general baseline rate and lets you adjust it — use it to model different scenarios, then confirm your exact rate using the official HTS lookup tool or a licensed customs broker before you rely on the number for an actual shipment.
Sector Surcharges (Section 232)
Separate from the general baseline, Section 232 tariffs apply an additional surcharge (commonly cited around 25%, and higher for some wholly-metal articles) on steel, aluminum, passenger vehicles, and many auto parts, regardless of country of origin. If you're importing one of these categories, use the quick "Steel/Aluminum/Autos" preset or enter your own known surcharge rate.
What Counts as Customs Value?
Customs (declared) value is generally the price actually paid or payable for the goods themselves — not including international freight and insurance in most valuation methods, which is why this calculator keeps freight/insurance as a separate field and adds it back in only for the landed-cost total, not the duty calculation itself.
