Calculate stacked tariffs (MFN, Section 301, Section 232, additional) and compare alternative sourcing.
| Country | Tariff | Labor |
|---|---|---|
| Vietnam | 10% | Low ($180-280/mo) |
| Mexico (USMCA) | 0% (Free) | Medium ($400-600/mo) |
| India | 10% | Low ($150-250/mo) |
| Taiwan, China | 10% | Medium ($700-900/mo) |
Tariff rates are simplified to product category level and represent current rates as of Aug 2026, after the Supreme Court struck down IEEPA tariffs and a 10% Section 122 baseline took effect (USMCA-compliant goods exempt). Actual rates depend on specific HS codes (10-digit), country of origin, and applicable exclusions. Rates change frequently due to executive actions. This tool is for estimation only — consult a licensed customs broker for accurate tariff classification.
A US import can owe several duties at once. Every shipment is first classified under the Harmonized System (HS), which fixes the MFN (most-favored-nation) rate — the ordinary tariff the US applies to its trading partners. Trade-war measures then stack on top: Section 301 tariffs target specific countries and products (China, solar panels, EV batteries), Section 232 tariffs cover steel, aluminum, and autos on national-security grounds, and since the Supreme Court struck down the IEEPA tariffs, a 10% Section 122 baseline applies to most non-USMCA imports (USMCA-compliant Mexico and Canada goods are exempt). Each layer is computed on the same CIF dutiable value (goods + freight + insurance) and then added together, so the combined rate can be far larger than any single line. Because retailers typically mark goods up 2–3×, a 35% import-duty stack still lands as roughly a 14% increase at the checkout.
Sample: $50,000 of phones (HS 8517) shipped from China with $2,000 freight and $300 insurance. MFN duty on electronics is 0%; the stack is Section 301 (25%) plus the Section 122 baseline (10%), both on the $52,300 CIF value.
Maya imports $50,000 of electronics (HS 8517) from China into the US, paying $2,000 for freight and $300 for insurance. Electronics have no MFN duty, but China faces the Section 301 surcharge and the Section 122 baseline.
Calculate true landed cost including stacked US tariffs (Section 301 + 232). Free.
The Tariff & Trade War Cost Calculator models how layered US trade actions stack onto one invoice. Instead of a single duty rate, it breaks imports into four components: the baseline MFN rate, Section 301 tariffs on Chinese goods, Section 232 steel and aluminum national-security tariffs, and the additional 2025 China measures. You choose among ten product categories, each pinned to a representative HS code, from electronics (8517.62) and apparel (6109.10) to solar panels (8541.40) and EV batteries (8507.60), pick an origin among fourteen countries, and optionally fold freight and insurance into the dutiable value. The result separates each tariff layer, shows a combined rate, and, for electronics and apparel, compares alternative sourcing countries with tariff, labor cost, and lead time.
Importers and product managers sourcing from China use it to quantify tariff exposure before renewing purchase orders, since a Chinese electronics shipment can face a combined rate near 45% (0% MFN, 25% Section 301, 20% additional) and steel products up to 70%. Procurement teams evaluating reshoring run the alternative sourcing table, which contrasts Vietnam and Mexico (USMCA, tariff-free) against Bangladesh and India for apparel. Small manufacturers pricing 2026 catalogs translate duty into retail impact using the built-in 2-3x markup estimate. Consultants and journalists explaining trade-war mechanics use the stacked bar visualization, and students of supply chain finance trace how each legal authority contributes separately. Anyone needing a legally binding 10-digit HTS classification should still confirm with a customs broker.
(1) Enter the FOB product value, pick a category and country of origin, and toggle whether freight and insurance join the dutiable base; the sample scenario loads $50,000 of electronics from China with $2,000 freight and $300 insurance. (2) The engine adds optional freight and insurance to product value, then applies each layer independently: MFN duty, Section 301 (25% for Chinese origin), Section 232 where the category qualifies, and the 2025 additional rate, so solar panels from China sum 0%, 25%, 0%, and 50%. (3) Review total import duty, the combined percentage, landed cost, a stacked bar splitting the layers, and a consumer-impact note estimating retail price growth under typical 2-3x markup.
Mostly yes, because Section 301 and the 2025 additional tariffs key off country of origin, and thirteen of the fourteen origin options in this tool carry zero surcharge, paying only the category's MFN rate. The alternative sourcing table quantifies the trade: Mexico under USMCA ships tariff-free with a five-day lead-time advantage but medium labor cost, Vietnam adds 7-14 days at low cost, and Taiwan adds 3-5 days at medium cost. Two warnings matter. Origin follows substantial transformation, not the port of shipment, so routing Chinese goods through Vietnam rarely changes their classification and transshipment is fraud. And MFN rates still apply everywhere, such as the 12% on apparel, so the calculator keeps that floor visible when you compare scenarios.
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.
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.
