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.

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 tariff is a percentage tax on the customs value of imported goods, paid at the border before the goods release. Importing $100,000 of goods under a 25% Section 301 tariff costs $25,000 extra in duty — landed cost rises by that amount unless you renegotiate supplier pricing. The calculator prices that duty into your per-unit economics so you can see the real margin after the border, not the invoice before it.
Legally the importer of record pays Customs; economically the burden is shared and shifts with bargaining power. Studies of the 2018-19 China tariffs found near-complete pass-through to US import prices — exporters rarely cut prices enough to absorb it. Practically: with a commodity supplier you eat it or pass it on; with a long-term factory relationship you can negotiate a split, source from a third country, or apply for exclusions where they exist.
Every product has a 10-digit HTS code determining its base rate (Column 1 general), and additional duties stack on top by origin and program: Section 301 (China), Section 232 (steel/aluminum and derivatives), IEEPA-based actions, and reciprocal tariff schedules have all layered since 2018. Classify your product first — misclassification is the most common (and penalized) error — then check the current action list for your origin country; the calculator applies the rate you establish for the landed-cost math.
The main levers: tariff engineering (classifying or designing products into lower-rate categories — legally done constantly), first-sale valuation (duty on the factory's price rather than the middleman's), foreign trade zones and bonded warehouses (defer or eliminate duty on re-exported goods), duty drawback (refund for imported goods later exported), and USMCA-qualifying sourcing for North American trade. What you cannot do is undervalue invoices or misstate origin — penalties run 2-10x the underpaid duty.
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.
